As Boris Johnson announces that HS2 is to forge ahead with a new streamlined plan, the debate will continue to rage. The overall costs, suggested by some, to be nearer to 160Bn rather than the latest projection of 106Bn being the biggest contention, with other considerations, such as the loss of woodland also being sited.

The major justification for HS2 is to increase economic growth with its deployment providing an extra 15Bn a year by 2037. Many a fine phrase is quoted about productivity and skills deployment in the usual misty way of government, leaving the majority of us completely in the dark as to how this economic growth will actually happen. What is apparent is that in the main the argument for HS2 is about getting people rather than produce more quickly from the North to the South and joining up the largest of the Northern cities, in order to feed those area’s growing need for the skilled labour and so increase economic growth. This suggests the type of skills required are not the highly paid industry professionals but rather those of us that earn a living wage for skills that lie in their physical abilities to make real the dreams of the professional. The concept that those most needed individuals would be able to afford to commute to the cities that require them, saving the extra travel minutes that will be available by using HS2, seems to say the least unrealistic.

What we hear little of with regard to HS2 is its impact on the transportation of freight. With the prospect of our trade deals more likely to move across the Atlantic rather than the channel it would seem that distribution from our ports and airports will be critical. Given the right planning an improved rail infrastructure could be very positive in addressing the transportation of goods and help to alleviate the severe commercial congestion on our roads. Planning is the important factor where this is concerned and many fear that it has not been properly thought through in relation to HS2.

The question ‘Will HS2 stimulate economic growth?’ was asked as part of a report by the Economic Affairs Committee which was ordered by the House of Lords in 2015, the following is the conclusion to that section of the report which can be read in full from this link.

Evidence we have heard shows that investing in transport infrastructure does not necessarily lead to economic growth. Improvements in transport infrastructure need to be carefully chosen and linked with other policies to ensure that money is spent where it can be most effective in stimulating growth.

We heard evidence that London was likely to be the biggest beneficiary from HS2. This has been the case with similar projects in other countries where the largest cities have benefitted the most, including in France where Paris was the biggest beneficiary from the TGV. This does not mean other cities may not receive some economic benefit from HS2, which could stimulate growth and play a role in rebalancing the economy if coupled with appropriate policies to foster economic growth.

HS2 must not lead to a reduction in investment in improving other areas of the UK rail network. Investment on lines such as the East Coast Main Line north of Leeds, or rail services elsewhere in the country, could play an important role in stimulating growth outside of the South-East. Any reduction as a result of HS2 could mean these areas lose out.

Stations located outside city centres as proposed for Sheffield Meadowhall and the East Midlands Hub HS2 stations are less likely to bring economic benefit to the cities in which they are situated. Where stations cannot be located in city centres they must be properly connected into regional transport networks to ensure the maximum benefit is derived from them.

It is important that stations are linked into local transport networks in order to reduce the risk that HS2 brings little or no economic benefit to nearby areas. We agree with the Growth Task Force that the Government should provide leadership nationally to ensure that the right steps are taken to prepare cities with stations for HS2.

As noted in Chapter 2, concerns have been raised that the full cost of complementary projects required to maximise the benefits of HS2 have not been captured. The cost of any additional work undertaken in cities to ensure the maximum benefit is derived from HS2 and who is to pay for it needs to be made clear to ensure the right decisions are made.

Rail freight is important to the UK economy, but it has largely been ignored during the development of plans for HS2. The Government should set out in more detail how HS2 will benefit rail freight and how it will address the concerns raised by the freight industry.

This is largely reported from a personal and perhaps uneducated viewpoint, but surely the taxpayer, who will ultimately pick up the bill for HS2, has a right to ask simple questions of the government and receive straightforward answers.

It is well documented that Mr. Johnson has a great fondness for grandiose infrastructure schemes such as the airport on the Thames and a bridge to Ireland, perhaps HS2 will prove the construction legacy of his leadership. As so many other individuals in power have suggested, history will tell the story, each hoping that the story would favour rather than damn them to posterity.

Commenting on this month’s figures, Rhys Gadsby, Glenigan’s Economic Analyst, said: “The latest Glenigan Index reveals a subdued start to the New Year for construction. The value of underlying project starts dropped 11% during the three months to January. Political uncertainty and delay ahead of the general election contributed to the fall. The more certain political environment should now enable postponed public-sector projects to proceed to site and will hopefully lift investor confidence over the coming months.

“Private Residential starts weakened further during the three months to January. Private housing starts fell by 12% against the preceding three months on a seasonally adjusted basis and were 18% down on a year ago. Social housing starts dramatically slipped back, falling by 46% against the previous three months and were 45% down on a year ago.”

“Overall non-residential projects slipped 3% against the preceding three months on a seasonally adjusted basis and were 1% lower than a year ago. Offices, education and community & amenity grew by 12%, 7% and 30% respectively against a year ago. Growth in these areas was largely offset by weakness in other non-residential sectors. Health starts slipped back during the last three months, falling by 31% on a seasonally adjusted basis, and decreasing by 21% against a year ago.

Retail and hotel & leisure starts were 19% and 10% lower respectively than a year ago.

“Civil engineering starts edged 2% higher against the previous three months on a seasonally adjusted basis but were significantly down on a year ago (22%). Utilities work rose by 6% against the preceding three months on a seasonally adjusted basis but was 27% lower than a year ago.

Most regions saw a decline in starts on a year ago. The North West, North East and the South West saw the sharpest declines, with the value of underlying starts falling by 52%, 51% and 29% respectively. There were also double-digit declines in starts in the East & West Midlands, and Yorkshire & the Humber. However, London, Wales and Northern Ireland were bright spots, with starts increasing by 14%, 63% and 27% respectively against the same period a year ago.

Benita Mehra resigned from the Grenfell inquiry after it was revealed that she had links to Arconic, the US company that made the aluminium composite material (ACM) panels that were on the tower.

Last week it was reported that Ms Mehra ‘has links to the company which made the cladding blamed for accelerating’ the fire. Earlier this month, the chartered engineer replaced Professor Nabeel Hamdi on the inquiry panel, with campaign group for the bereaved and survivors Grenfell United believing this was ‘snuck out just before Christmas’.

Grenfell United were ‘angered’ and disappointed that Professor Hamdi, an academic ‘with expertise in housing, design and planning’, was replaced by an engineer, and claimed it had not been ‘given an explanation for the change’. The group undertook research of Ms Mehra and revealed she had run the Women’s Engineering Society, which received a £71,000 grant from the charitable arm of Arconic – the Arconic Foundation – three months post Grenfell.

Arconic’s polyethylene filled panels had already been found by the inquiry to be ‘the principal reason why the flames spread so rapidly up the building’, and the grant was the ‘largest’ received in 2017 by the society. Grenfell United said this was a ‘clear conflict of interest’, with Ms Mehra’s appointment a ‘slap in the face’ for hopes of justice. It called for her to stand down before the second phase as it would examine ‘how the Arconic cladding panels were chosen, their safety testing, marketing and promotion’.

An inquiry spokesperson had been ‘confident that Benita Mehra’s former presidency’ of the society did ‘not affect her impartiality as a panel member’, while a Cabinet Office spokesperson said there were ‘robust processes’ to ensure that ‘any potential conflicts of interest are properly considered and managed’, adding that ‘the Arconic Foundation donated to a specific scheme which provides mentoring for women in engineering and is unrelated to the issues being considered by the inquiry’.

 

Error, group does not exist! Check your syntax! (ID: 4)

 

Mr Johnson had said that officials had ‘not identified any concerns’ with Ms Mehra’s appointment, and she had ‘confirmed that she is not aware of any conflict of interest’. An Arconic spokesperson said the foundation was ‘independently endowed and managed’ to ‘advance science, technology, engineering and mathematics education and training worldwide’, and create access to those fields for women internationally, with the 2017 grant ‘purely on this basis’.

Mr Johnson later told survivors he would investigate Ms Mehra’s role, at a pre arranged meeting with community representatives at Downing Street. Mohamed Ragab, whose nephew Hesham Rahman died in the fire, noted Mr Johnson ‘said he had no idea about this woman dealing with this company’, and ‘would have to investigate and find out what is going on’.

An anonymous attendee commented that Mr Johnson ‘didn’t seem to know who she is’, and promised that ‘this would be definitely be investigated’, as well as that ‘anything that causes us discomfort should not be allowed to happen’. The Guardian reported over last weekend that Ms Mehra had stepped down over the connections to Arconic ‘less than 48 hours before’ the inquiry resumed, Mr Johnson announcing that he had accepted her resignation.

He added that ‘as the inquiry’s phase two hearings begin, we remain completely committed to getting to the truth of what happened, learning lessons and delivering justice for the victims’, while Ms Mehra’s resignation letter to him stated she had made ‘a regrettable oversight’ and was resigning ‘with deepest regret’. She added it was apparent that the link to Arconic ‘has caused serious concerns to a number of the bereaved, survivors and resident core particpants’.

However, she stressed she had ‘never spoken to anyone’ at Arconic and that her only role had been to review the initial proposal. Mr Johnson’s private secretary Emily Beynon accepted the resignation but said that the Cabinet Office ‘having made further inquiries into your case, have said that they continue to believe that there is no conflict of interest that would have prevented you from taking part in the Inquiry’.

Grenfell United said she had done ‘the dignified thing by resigning’, and that it ‘helps lifts growing anxiety ahead of phase two’, but added: ‘The government should never have put families in this situation, they failed to carry out basic checks and understand the importance and sensitivities around a fair and proper process. We still have questions for both the inquiry team and Cabinet Office to answer, as to how this situation was ever allowed to happen.

‘The government promised two panel members and must now urgently find a new panellist, to bring expertise on community relations to the inquiry. We do not need the pretence of diversity for the sakes of diversity. The panel does not need another technical expert where we already have ample provision.’

Urban Exposure continues Midlands push with £43m loan for development in central Derby

 

Urban Exposure plc (“Urban Exposure” or “the Company”), a specialist real estate financier and asset manager, has provided a loan worth £42.9m to a joint venture vehicle with BBS Capital (“BBS”) and Wavensmere Homes (“Wavensmere”). The loan will help to fund the development of 474 residential units known as Nightingale Quarter at the site of the former Derbyshire Royal Infirmary in Derby City Centre.

 BBS has joined forces with James Dickens’ Wavensmere Homes and Grahame Whateley’s Cedar Group to deliver the development. BBS’s investment management business has coinvested in the city centre scheme, supported by the £42.9m development finance facility provided by Urban Exposure. The site was once home to the Derby Royal Infirmary, it will deliver 349 apartments and 125 town houses over 3 phases, work began on-site in mid-December.

The Nightingale Quarter is well located to the southeast of Derby City Centre, fronting on to London Road, Osmaston Road and Bradshaw Way. The site is adjacent to Royal Infirmary Hospital and is a 5-minute walk from the Intu Derby Shopping Centre, and Derby Midland Train Station.

The first phase of sales will launch at the end of February 2020, with the first houses slated for delivery by the end of September 2020.

Commenting, Randeesh Sandhu, CEO of Urban Exposure, said:

“We are delighted to be supporting a project that will be transformative for central Derby, supporting the delivery of much needed housing for the local population. The site has been disused for several years, which makes it all the more pleasing to provide Derby’s residents with an opportunity to live in a thriving new community in an exceptional location.

 

We are also pleased to be working with BBS and Wavensmere who have an excellent track record and a clear desire to work on further developments in the midlands, a region where Urban Exposure has significant experience and has now provided £150m of development finance in the past eighteen months.”

 

Nick Spencer of BBS commented:

 

“We have worked with James and Grahame for some time in an advisory capacity but are delighted to have agreed this joint venture to deliver an urban regeneration project of this nature.  The Nightingale Quarter will offer Derby residents the best of urban living in a carefully designed community which will offer a large proportion of green space and on-site leisure amenity whilst also paying homage to the historic nature of the site.”

Construction on Expo 2020 Dubai’s crown jewel, the world’s largest 360-degree projection dome, is complete.

The steel trellis that makes up Al Wasl’s dome, with sand-coloured screens, has been fitted with more than 200 projectors and is wide enough to fit two Airbus A380s.

Al Wasl – meaning connection in English – is the World’s Fair centrepiece, connecting the districts, and will host its main ceremonies.

With this, Expo-led construction of permanent structures has been completed on the Dubai South site and testing of lighting has begun across the three main theme districts divided into Opportunity, Mobility and Sustainability zones.

All infrastructure and major landmarks – including fidget-spinner shaped Mobility Pavilion and the disc-shaped Sustainability Pavilion – have all been completed, expo officials said during a tour of the site on Monday.

“Al Wasl is really the jewel of the site because it will be the central hub,” said Katy Granville, who works with the Expo’s community engagement team.

“This is where the biggest celebrations will take place. When you see the crowned dome as you drive into work every day, it’s really a symbol of all the work being done and we are most proud of it.”

During the six-month expo, images will be beamed via projectors on to surface of the translucent dome and will be visible both within and outside the site.

The massive dome’s architectural design is linked to the country’s history and heritage. The outer cover resembles the world fair logo which was inspired by an ancient golden ring found in the Saruq Al Hadid site by Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai. Artefacts uncovered at the site date back to the Iron Age.

Meticulous and careful engineering precision was needed last year to raise hundreds of tonnes of moulded steel and fit the crown of the dome to the top of Al Wasl plaza.

With nine months until expo opens, on October 20, about 40,000 workers are on site operating cranes, transporting material and fitting out interior work.

Clusters of date palms have been planted in roundabouts and line several paths leading to the theme districts.

A media tour of the site on Monday showed work being completed on the iconic white UAE pavilion, the largest on the expo site, which resembles a falcon in flight.

Dozens of tourists and residents also gathered to be part of a tour of the sprawling area as part of the World’s Greatest Show in the Making Tour launched to familiarise people with the offerings.

Extensive work is under way on the Saudi Arabia pavilion that spans an area equal to two football pitches.

Surrounding Al Wasl Plaza is a 55-metre high observation tower where visitors will be able to catch a bird’s eye view of the site and Jubilee Park, one of the main green lungs that will host open-air concerts with a capacity for 15,000 people.

On another end of the 4.38 sqkm site, about 2,000 flats are being readied at the Expo Village for staff who must live on site for until the fair ends in April.

Hectic work was also under way in the winged metal structure of the emirate’s largest metro station. Part of the Roads and Transport Authority’s Route 2020 project, the station will connect the expo to the city’s main metro line and ferry more than 20,000 passengers every hour in each direction.

After reviewing costs and alternative plans, the chancellor is expected to support the scheme.

Chancellor Sajid Javid is set to throw his weight behind the controversial HS2 rail project.

Mr Javid is minded to support the high speed train initiative at a meeting with Prime Minister Boris Johnson and Transport Secretary Grant Shapps on Thursday.

 

Error, group does not exist! Check your syntax! (ID: 4)

 

The PA news agency understands that having reviewed costs and alternatives the Chancellor will “broadly back” the high-speed line from London to Birmingham, Manchester and Leeds.

Mr Shapps has insisted that no decision on the controversial infrastructure project – the biggest in Europe – will be announced this week.

It has been estimated the scheme, which was allocated £56 billion in 2015, could cost up to £106 billion.

The Prime Minister told the Commons on Wednesday that a decision on the project would be made “very shortly”.

Some £8 billion has already been spent on the scheme.

He said: “I just want to reassure all of my honourable friends and everybody, whatever persuasion they may be about HS2 across this Chamber, that there will be an announcement and a decision very shortly.”

The meeting comes as Mr Javid has put pressure on Cabinet colleagues to identify where cuts of 5% could be made in their departmental budgets.

In a letter, co-signed by Mr Johnson, the Chancellor urged ministers to identify projects that could be abandoned ahead of his first Budget as Chancellor in March.

The intervention was seen at Westminster as a bid to find resources to fund Tory election promises on infrastructure, health and law and order.

Whitehall’s spending watchdog said this month that HS2 is over budget and behind schedule because its complexity and risks were under-estimated.

The National Audit Office (NAO) warned that it is impossible to “estimate with certainty what the final cost could be”.

Phase One between London and Birmingham was due to open in 2026, but full services are now forecast to start between 2031 and 2036.

Business chiefs in the north of England have argued that pushing forward with HS2 is key to boosting transport links across the region and providing increased capacity on the overcrowded rail network.

Construction firms warn that scrapping it would cause major damage to the industry.

However, opponents insist HS2 is too expensive and the money would be better spent elsewhere, while several environmental groups say it would cause huge damage to natural habitats and ancient woodland.

More rough sleepers will be helped off the streets and into safe accommodation thanks to an extra £112 million funding for councils, Housing Secretary Robert Jenrick MP has announced on the 28 January 2020.

This funding is a 30% increase this year and will be used by local authorities, charities and other organisations to fund up to 6,000 bed spaces and 2,500 support staff across the country.

This will help vulnerable rough sleepers get the support they need to rebuild their lives. It could mean a roof over their head, access to specialist mental health or addiction services, or advice on how to secure a home in the long term.

 

Error, group does not exist! Check your syntax! (ID: 4)

 

Housing Secretary Robert Jenrick MP said:

No-one should have to face a night on the street and we have a moral duty to support those who need help the most. It is encouraging to see more people getting the support they need, but there is always more to do.

We are focusing relentlessly on this issue and our efforts have already led to the first nationwide fall in rough sleeping in a decade – and the areas funded by our Rough Sleeping Initiative have seen rough sleeping numbers fall around a third more than they would be without this vital programme, but we need to go further. That is why we are providing this funding so vital work can continue as we set out to end rough sleeping once and for all.

Homelessness Minister Luke Hall said:

There are people all over the country working tirelessly to improve the lives of the most vulnerable in our society. Our Rough Sleeping Initiative is proving to be successful, and this funding will mean this vital work can be continued as we set out to end rough sleeping once and for all.

The Rough Sleeping Initiative was launched in 2018 to ensure local areas were given the boost they needed to provide these vital services for those living on the streets.

This will give people access to a roof over their head when they need it most – as well as the help they need to recover from a life on the streets.

We have seen the first nationwide fall in rough sleeping in a decade – and this comes as the government is facing a significant challenge following a large increase in the number of non-UK rough sleepers coming to the UK.

For example in Westminster it’s estimated that 49% of those sleeping rough are non-UK nationals and work continues across government to support these individuals.

Government funding for rough sleeping has already helped thousands of people to improve their lives and get off the street. This is a coordinated effort across housing, addiction support, mental health services and policing.

We intend to continue to bring all parts of government together to end rough sleeping by the end of this parliament.

For example, Southwark Council is working in partnership with all NHS local agencies to help end rough sleeping in their area. The council has placed a housing navigator within the 3 local NHS hospitals to coordinate a joint health and housing response to ensure no patient is discharged to the streets.

The council, through Rough Sleeping Initiative funding, has also employed one nurse to work in partnership with the outreach team to ensure any person sleeping rough has access to health care. The rough sleeper will also automatically qualify for council housing following the referral from the nurse.

This partnership has ensured 41 people sleeping rough have been now been rehoused with support into suitable accommodation.

The funding will be used by councils to:

  • Create street-based services including outreach teams who will locate and support rough sleepers directly on the streets and offer them access to services
  • Establish first stage accommodation such as hostels, Somewhere Safe to Stay hubs and emergency access beds which provide warm and dry shelter, rapid assessment, and support to people who are already – or at risk of – sleeping rough
  • Set up housing support providing stable, affordable accommodation and intensive wrap-around support to help people who are sleeping rough recover from complex issues and sustain their tenancies
  • Introduce specialist support workers including Rough Sleeping Coordinators, navigators, and specialist health and care staff

The funding follows the Prime Minister’s drive to tackle homelessness and the announcement of over £260 million for local authorities. This will help people who are homeless or at risk of losing their homes improve their lives and get back on their feet.

Did you know the average British person spends 22 hours a day inside? That’s around 90% of their overall day. The reasons cited for this are many, from adverse weather conditions to work commitments. Developing technology is partly to blame, with TV’s, smart devices and consoles proving too addictive for many to peel themselves away from for prolonged periods of time. But technology is also part of the solution, transforming the great indoors into a healthy environment in which we can thrive. Joe Bradbury of buildingspecifier.com discusses:

On a typical weekday the average Brit spends just 8-10% of their time outside (less than two hours) and most of this is spent moving from one building to another on foot or by car. Unfortunately, this is also true of our children too; 36% of parents think their kids are not spending enough time outside, whilst 1 in 6 are uncertain themselves of how much time outdoors is actually sufficient.

Studies show that over half of parents worry that their young ones are spending significantly less time out than they themselves did when they were children, indicating an overall shift in behaviour as a society.

Whilst it is critically important that we all get outside as much as we can and appreciate nature in all its splendour, it is also vital that our technology moves with the times to ensure the indoor environments we inhabit are not taking a toll on our health and wellbeing.

Invisible threat

Sat comfortably inside our homes, offices and schools we pay little mind to the invisible threats posed by poor quality air. But those harmful gases, chemicals, toxins and pollutants that we unwittingly breathe are responsible for many of the migraines, skin and eye irritations, allergic reactions and general tiredness that plague us all from time to time.

Experts agree that poor indoor air quality in UK homes is at a scale and magnitude that needs immediate national-level attention and action.

Both built environment and medical professionals recently came together to highlight the true danger of poor IAQ, which alarmingly is responsible for around 40,000 deaths throughout Britain each year. The Royal College of Physicians, the Royal College of Paediatrics and Child Health, BRE and the ARCC network released a report revealing the lack of robust, longitudinal, shared Indoor Air Quality (IAQ) profiles, associated health consequences and datasets across the national housing stock.

Recommendations included revising building regulations and reducing pollutant emissions from construction materials and home improvement products.

Professor Stephen Holgate, Special Advisor on Air Quality to the Royal College of Physicians said “There is a growing body of evidence that suggests volatile organic compounds (VOCs), are also being produced by synthetic building and furnishing materials. At the same time, insulating homes without adequate ventilation can trap a potentially toxic cloud coming from everyday household products such as air fresheners and cleaning products.

“We need to strike a balance between talking to technologists to develop solutions for those able to improve the situation within their own means and ensuring effort is going into “making normal better.”

The report also called for nationwide monitoring and pooling of data required for outdoor and indoor air pollution including encouraging widespread installation of real time sensors that detect indoor pollutants.

It is said that time is a great healer; however, when a serious issue (such as poor indoor air quality) is ignored then in time the damage it can inflict on our bodies can be fatal. Prolonged exposure to serious pollutants found throughout British buildings leads to the development of certain kinds of cancers long-term health concerns.

On average, 3 people a day die from asthma. There are 5.4 million people (1.1 million children and 4.3 million adults) in Great Britain known to be suffering from the condition… and they are just the ones that came forward for treatment. An untold number battle through their symptoms

undiagnosed. The UK has some of the highest asthma rates in Europe. Every day, the lives of three families are devastated by the death of a loved one to an asthma attack, and tragically two thirds of these deaths are preventable.

Indoor air quality is essential in the treatment and prevention of Asthma, along with many other respiratory conditions.

Tech that can help

If you work in the construction industry, you may have already been specifying devices aimed at improving IAQ, such as air filters and heat pumps as part of your workload. But for those who have yet to come across them, allow me to explain how they work:

MVHR (Mechanical Ventilation with Heat Recovery) provides fresh filtered air into a building whilst retaining most of the energy that has already been used in heating the building. Heat Recovery Ventilation is the solution to the ventilation needs of energy efficient buildings. Mechanical ventilation with heat recovery (MVHR), heat recovery ventilation (HRV) or Comfort ventilation are all names for the same thing. A heat recovery ventilation system properly fitted into a house provides a constant supply of fresh filtered air, maintaining the air quality whilst being practically imperceptible.

MVHR works by extracting the air from the polluted sources e.g. kitchen, bathroom, toilets and utility rooms and supplying air to the ‘living’ rooms e.g. bedrooms, living rooms, studies etc. The extracted air is taken through a central heat exchanger and the heat recovered into the supply air. This works both ways; if the air inside the building is colder than the outside air then the building will retain its nice and cool temperature.

An airtight building with effective filtration and ventilation is proven to reduce particle penetration by 78%.

 

In summary

Everyone is at risk from indoor air pollution. As a civilisation, we of course need to treat the causes of this pollution, by cleaning up our act and lowering our carbon footprint. In the interim however, the construction industry will play an invaluable part in treating the symptoms of our misdemeanours, developing and installing technologies that will allow us all to breathe a sigh of relief whilst indoors.

As an industry, we have the power to ensure the safety of the users and occupants of buildings nationwide. We still have a way to go, but Britain is taking valiant steps towards a sustainable and healthy future and addressing the pressing issue of poor indoor air quality across the country is paramount. Do not underestimate your role in this sea change as a building specifier… what you can offer is a breath of fresh air!

 

Considering all of the water in the oceans of the Earth, it’s no surprise that researchers the world over are hammering away at the challenge of extracting renewable energy from the sea. Now a team based in Australia has come up with a solution that leverages osmotic pressure to do the trick. In an odd twist, recycled Kevlar could also come into play.

Renewable Energy From Seawater: Great Idea!

For those of you new to the topic, osmosis refers to the passage of water through a membrane. The electricity angle comes in with the seawater.

Think salt and ions, and you’re on the right track.

If sea water is separated from fresh water by a membrane, the two sides will seek a balance. That puts pressure on the membrane, and pressure can be converted to energy.

That sounds simple enough, but the devil is in the details. The Australian team, based at the Institute for Frontier Materials at Deaking University, explains that osmotic membranes “must combine high mechanical properties with high surface charge, nanochannel density, scalability of production, and environmental resilience.”

Renewable Energy From Seawater: Bone Edition

Researchers have been messing around with osmotic pressure to generate electricity since at least the 1970s, but much of their work stayed in the lab.

The potential for commercial application has begun to pick up in recent years, thanks in part to advances in fabrication methods that enable researchers to assemble new materials at the nanoscale.

The Australian project is a good example of how quickly the field of osmotic energy (aka osmotic power or “blue” energy) could accelerate from here on out.

The team was inspired by osmotic activity in the human body. In particular, the researchers took note of the strong-weak contrast between bone and soft tissue, coupled with the contrast in their ability to transport ions.

Bone is very strong, so a new material based on bone structure could make a strong membrane. Unfortunately, bone is very bad at transporting ions.

Soft tissues like cartilage and kidney membranes are very good at transporting ions, but their structure would make for a very weak membrane.

The solution was to create a composite membrane using nanoscale layers of each material. The research team chose fibers of aramid to stand in for soft tissue, and boron nitride platelets for bone.

Renewable Energy From Recycled Kevlar?

If you caught that thing about boron nitride, that’s important in terms of the commercial success of the new membrane because it is relatively cheap.

Boron nitride platelets form a powdery substance that is widely used to control heat in consumer electronics, batteries, and many other applications.

The aramid angle is even more interesting. Aramid refers to the kind of synthetic fibers that go into making Kevlar vests and other high performance gear.

Aramid recycling is already a thing, and the team anticipates that the use of recycled aramid fibers in their new membrane will also help keep costs under control.

More Renewable Energy From The Ocean

For complete details on the new membrane you can look up the study, titled “Bioinspired Nanocomposite Membranes for Osmotic Energy Harvesting,” in the journal Joule.

For those of you on the go, one of the key findings is that the new membrane demonstrates “high stiffness and tensile strength even when exposed to repeated pressure drops and salinity gradients.”

The new membrane also displays promise in the areas of power density and range of temperatures:

“The total generated power density over large areas exceeded 0.6 W m−2 and was retained for as long as 20 cycles (200 h), demonstrating exceptional robustness. Furthermore, the membranes showed high performance in osmotic energy harvesting in unprecedentedly wide ranges of temperature (0°C–95°C) and pH (2.8–10.8) essential for the economic viability of osmotic energy generators.”

The team still has some work to do in terms of optimizing the performance, so don’t look for that new membrane on the shelves of your local hardware store any time soon.

The important thing is that osmotic systems expand the range of options for harvesting energy from the ocean — as opposed to, say, drilling into the ocean bed for oil and natural gas.

Offshore wind turbines are already firmly established in the renewable energy marketplace, and floating wind turbines are coming up fast. Wave energy and tidal energy devices are also in play, and the US Department of Energy is hot on the trail of other emerging forms of ocean energy.

Meanwhile, Stadkraft has an osmotic energy facility in operation since 2009. CleanTechnica is reaching out to the company for an update, so stay tuned for more on that score.

Global OTEC Resources has announced that islands in the Maldives can apply to be off-takers of its first OTEC demonstration barge which is set for launch next year.

Applications are now open until January 31, 2020, to buy energy produced by an England-based clean energy systems developer.

Ocean thermal energy conversion (OTEC) is an application of solar energy in which the heat that the ocean captures from the sun’s rays is used. It is a technology for converting some of the energy that the tropical oceans absorb from the sun, first into electricity and then into fuels.

Global OTEC Resources are offering energy rates comparable with existing diesel infrastructure and potential off-takers will be required to submit a bid for the kWh unit cost they are prepared to pay.

The demonstration barge will house a 150 KW OTEC plant that will generate 1,185 Mwh annually.

According to the company, this scaled-down system could provide local islands, such as Fenfushi, with 100 per cent of its yearly electricity demand. For island resorts, it would provide between 20 per cent to 50 per cent of average energy requirements.
