Rinnai’s Chris Goggin explores how wider electrification of the UK domestic & commercial energy mix could influence decarbonisation efforts and customer choices of heating and hot water appliances.

Will Britain’s national electrical grid hold the capability of handling extra demand?

As part of the recent “Powering Up Britain” Govt document, wider electrification was specified as a key strategic aim in decarbonising the UK. Future domestic & commercial & industrial energy will be provided through several ways, one method of decarbonisation will focus on producing sustainably sourced and cheap electricity for UK customers.

There is a series of logical steps if NetZero is to be achieved by 2050. If the UK is going to proceed with decarbonisation through electrification, then providing the electricity for the mass use of electric vehicles will be key. To power an Electric Vehicle (EV) requires the widespread availability of charging points across the UK. There are over 33 million vehicles on the UK’s roads, the majority of which will require electricity.

Can current National Grid capacity cope with increase of electric vehicles AND the demand surge for domestic, commercial and industrial usage facilitated through wider UK electrification?

A BBC article published just recently has revealed that clean energy projects are being put on hold due to a lack of electrical grid capacity. Some renewable energy companies believe this lack of electrical grid capacity could potentially negate the progress of UK NetZero targets.

It has been estimated that the UK requires five times more solar power and four times as much wind generation than what is being presently manufactured. All of which will need to be connected to the national grid. The BBC report estimated that £200 billion of clean energy projects are waiting to be connected with 40% of these projects facing at least a year of further procrastinating.

UK decarbonisation aims are centred on the dispersal of clean and cheap electricity. However, relying on renewables in the short term to completely satisfy national energy supplies is not risk adverse. Renewable power yield relies on weather conditions that seasonally fluctuate.

Although possible, there are still theoretic and technical challenges that require addressing before the UK electric grid can be considered capable of handling both wider national electrification and the inclusion of EV’s on UK roads.

Electricity is generated through various renewable and non-renewable practises such as wind, solar, tidal, nuclear and natural gas. Although UK energy policy makers are keen on reducing and eventually phasing out fossil fuel usage altogether, natural gas has been recognized as a key decarbonising transitional fuel source, as it is used in times of low wind yield to produce electricity (wind being the second highest contributor to UK electrical generation at 25%).

UK policy makers have identified cheap and sustainable electricity as a main contributor to national decarbonisation efforts. As a result, the UK’s electrical capacity grid will have to be expanded. ‘Powering up Britain’ also states that energy independence can be achieved through potentially doubling Britain’s electrical capacity by 2030 whilst ensuring cost effective electrified power.

To provide continuity to UK home market energy supplies, a baseload of power is dispersed to communities throughout the UK. A baseload of power ensures that the minimum requirement of national demand is constantly met. Baseload energy demands are satisfied via energy sources that are cost effective and readily available, such as natural gas.

Dispatchable power are separate sources of energy that are utilized in times of peak demand. Throughout the calendar year the UK power grid will experience times of pressure where it is a necessity to incorporate additional energy to cope with demand and output.

Current capacity of the UK electrical grid stands at 334.2 TWh (terawatt-hour: a unit of energy equal to one trillion watts for one hour). It is estimated that with the inclusion of electric vehicles will create an additional 100TWh demand increase. That, in rounded terms, means an increase of about one third of current levels.

The UK electrical grid is designed to coincide with seasonal and daily peak times of demand. For example, in a seasonal context the demand for electricity is far higher in January then it is in July. Daily electrical demand rhythms are similar – evening demand is far higher than in mid to early afternoon.

Developments in technology, energy efficiency and inclusion of renewables mean that the UK electric grid needs to be positioned to deal with further output demand created by the anticipated but not guaranteed widespread EV adoption across the UK.

Work will also continue to develop V2G (vehicle-to-grid) technology that allows electric car owners to send excess un-used electricity back to the grid when demand is high further creating grid flexibility.

Inter-continental grid connections to countries such as France, the Netherlands, Ireland, Belgium and Norway are connected to the UK through sub-sea cables. This means the UK grid can access power from other nations in times of high demand and system stress, as well as import and export at financially beneficial rates.

The recent “Powering Up Britain” paper stated the UK government’s aim to accelerate delivery of strategic transmission upgrades by at least three years with the specific aim of reducing delivery time in half to UK customers. The Electricity Networks Commissioner will be advising the UK government on how to accelerate grid delivery and will present recommendations to ministers in June.

Rinnai understands the complexity of UK decarbonisation efforts and we are committed to informing UK customers on the detail and impact of current and future energy policy as well as shifts in the energy landscape that could affect customer cost.

Chris Goggin details construction projects and financial funding directly related to future widespread UK hydrogen usage. Customers of energy and all related products will be provided with insight into projects that involve hydrogen use and production by big business inside the UK and EU.

 

 


Future UK energy options will be clean, domestically sustainable and free from market interference. Low carbon alternatives will be gradually introduced in replacement of environmentally harmful fossil fuels. A form of future energy that fulfils a low carbon criteria and can be domestically manufactured is hydrogen.

The UK government has recently released their latest report detailing a future approach to hydrogen dispersal. In brief, present calculations for the use of hydrogen as an upcoming UK energy option will be limited to decarbonising hard to reach sectors of industry and transport. If scientific data that proves hydrogen adoption yields beneficial results, hydrogen could be used to heat domestic and commercial properties.

Various hydrogen projects are being pursued, constructed and installed by leading international energy companies such as Shell and BP as well as several other large UK energy operators.

Spanish renewable energy company Iberdrola will invest €170 million in constructing and developing a green hydrogen facility at Felixstowe, England’s largest port. Manufacturing capacity will be around 14,000 tons a year with the ambition to double this figure in the near future. All green hydrogen that is produced will be used to power port vehicles and machinery.

Norwegian state-owned oil and gas company Equinor has submitted a bid for UK governmental funding of £16 million with the aim of constructing a second blue hydrogen facility in the Humber region of England. A final investment decision will be made in 2025.

The Hydrogen to Humber (H2H) Production 2 site will be located close to Equinor’s H2H Saltend project – another blue hydrogen facility. Operations will begin in 2028 if the construction and approving processes are not complicated by unforeseen events.

Both Saltend and Humber projects will use natural gas to produce blue hydrogen and utilise CCUS technology (Carbon Capture & Underground Storage) that will detain a vast majority of created emissions. Equinor also received £8.4 million in governmental funding, a figure matched by private investments to begin Saltend construction.

Another big company hoping to deliver a hydrogen production facility is UK oil and gas company BP. BP has submitted plans to the UK government detailing their vision in constructing and running a green hydrogen hub that will supply clean energy to local industry, businesses and homes.

BP’s HyGreen Teesside project will be located in the Northeast of England. Production and distribution of green hydrogen will be targeted for 2025. MOU’s (Memorandum of Understanding) have been agreed with potential local buyers of end-product green hydrogen, signalling large demand.

One such MOU has been signed with Northern Gas Networks (NGN). BP and NGN will see 2,000 local homes and businesses powered by hydrogen from 2025. It is hoped that the installation of a regional hydrogen hub can assist in enabling a functioning hydrogen economy across the region and nation.

HyNet North West is a £750 million joint venture project that includes several big names such as Cadent, Essar Oil UK and Eni UK. Two blue hydrogen production facilities and CCUS technology will be constructed and inserted into Essar Oil’s Stanlow Refinery and be transported through yet to be assembled infrastructure.

HyNet’s hydrogen hub will contribute 80% of the UK’s 5GW low-carbon hydrogen target that will be utilized in industry, transport and domestic heating. All produced hydrogen will be distributed across Northwest England and North Wales. Operations could begin in 2025.

Two major European economies in The Netherlands and Germany have embraced hydrogen as a potential contributor towards decarbonising national energy resources. The Netherlands is in the process of retrofitting 136,000 km of natural gas pipelines to transport hydrogen for industrial and domestic consumption. The Netherlands “National Hydrogen Network” will be ready for operations in 2031.

Germany is encouraging large domestic industrial hydrogen transitions and residential hydrogen dispersal. German steel producer Salzgitter will spend €723m to replace industrial procedure involving coal with green hydrogen. The German government is also experimenting with trials that use hydrogen to heat properties.

European economies are keen on a switch to hydrogen. At present UK plans are not definitive on the role of hydrogen in the national energy transition, while an influx of data demonstrates the positive benefits of hydrogen usage into policymakers expanding its role in the UK energy transition.

RINNAI HYDROGEN BLENDS READY 20% CONTINUOUS

FLOW WATER HEATERS BEATS STORED WATER

SYSTEMS AT PREMIER LEAGUE CLUBS 

Property experts and contractors have completed the installation of a complete new hot water delivery system at a top London Premiership football club, replacing an outdated stored cylinder configuration with a practical and economic hot water solution. The renowned club replaced their old traditional system with a specifically designed new energy efficient Rinnai continuous flow delivery on demand water heaters that offer and are certified for Hydrogen blends of up to 20%.

Rinnai water heating systems have been installed in almost all top UK Premiership clubs in the UK. The latest installation was completed at a stadium which is less than 20 years old and was considered ‘state-of-the-art’ once completed. The club had initially utilised a traditional stored system where hot water is kept heated until required. The new system is capable of delivering over 9000 litres of temperature controlled hot water each and every hour, non-stop.

A premiership football club will have huge peaks of demand and the site simply cannot afford to run out of hot water on match days. The demand is for the kitchens, the catering, the hospitality, the toilets and the extensive wash and showering facilities.

Continuous flow systems heat water upon demand meaning that fuel is only used when the system is operational.

The installation completed at this London premiership club included a manifolded bank of 10 Rinnai Sensei N series 1600i continuous flow water heaters together with the Nexus scale protection and a BMS Integration. All units featured Rinnai commissioning to secure long term warranty guarantees.

For Rinnai Ricky Lewis, Associate Director Corporate Sales, said, “We were able to demonstrate that the Rinnai system can yield financial reductions of nearly 20% of the running cost, over 30% of the upfront cost, over 15% in carbon footprint, over 75% in space, over 85% in weight compared to heated storage systems, creating a highly practical and economic solution for the client whilst lowering onsite carbon.”

Rinnai continuous flow water heaters are an integral part of the organisations H1 initiative which aims to utilise natural gas, Hydrogen blends, Hydrogen, LPG and Bio-LPG to lower onsite emissions. Rinnai continuous flow units are typically 30kg – a one-man lift, making the entire installation process far easier. Two sizes are available – 47kW and 58kW. Both produce 774 and 954 litres per hour at a 50-degree rise respectively.

Rinnai H1 continuous water heaters and boilers offer practical and economic decarbonization delivered through technological innovation in hydrogen and renewable liquid gas ready technology. Rinnai’s H1 option is centred on hydrogen, as it is anticipated that clean hydrogen fuels will become internationally energy market-relevant in the future; Rinnai water heaters are hydrogen 20% blends ready and include the world’s first 100% hydrogen-ready hot water heating technology.

A GUIDE TOWARDS NET ZERO AND LOWER CARBON EMMISSIONS – UK ENERGY FOR THE FUTURE

 

 

 

Rinnai’s Chris Goggin lists a brief guide to national & local power variables that do, and might, in the future, supply the UK end-user and consumer. He looks at what is currently on offer and how that energy is manufactured and operates within the total UK mix of fuels.

 

As the UK is now firmly in an era of energy transition it is important that all interested parties – heating engineers, contractors, consultants and end-users – should be aware of what alternative energy is currently available and future options being actively considered.

Carbon heavy fuels are currently being phased out and replaced with a variety of low carbon alternatives. Instead of oil, natural gas and fossil fuel-generated electricity, renewable sources such as wind, wave and solar are being gradually introduced into the UK energy mix.

Biofuels such as BioLPG and RDME could also become UK market relevant along with green gasses such as hydrogen, which is supported by the UK hydrogen strategy and a myriad of pilot schemes across the UK. Energy policy in the UK is also planning to increase nuclear capacity with the construction of several new facilities, with the objective of providing low carbon electricity and potentially hydrogen. Following is a short exposition of each energy vector.

 

HEAT PUMPS

Heat pumps are an old but current technology – the first was invented by Peter von Rittinger in 1867. They can be considered zero carbon at the point of use. However, the carbon intensity of the system is dictated by the electrical grid generation method. A heat pump works by extracting heat from air outside and elevating its temperature using a compressor. Compressed heat Is then transferred into a body of water for heating and DHW.

Residual heat is stored in a hot water cylinder used for showers and baths. If installed correctly on to an appropriate property a heat pump will prove to be an energy efficient, effective tool of decarbonisation to the end-user.

Heat pumps are widely used in Scandinavian countries and other major European economies such as Germany. Mainstream UK media support heat pumps as do governmental grants that supply most initial purchase costs. Heat pumps are available with approved technology that encourages decarbonisation.

SOLAR ENERGY

 

Solar energy absorbs sunlight into photovoltaic panels which produces an electrical charge. This charge of electricity is then converted and transported into a domestic or commercial application. The UK government encourages domestic renewable energy installation. Homeowners can partly subsidise their solar panels through several governmental grants.
One example of UK homeowners incentivised towards solar thermal installation through a governmental scheme is the Smart Export Guarantee (SEG) which allows homeowners to receive payments for unused excess energy exported back to the national grid.

Solar power is viewed as holding the potential to contribute meaningfully towards the current and future domestic UK energy mix as well as multiple others across the globe. Only recently it was announced that Global renewable energy company – Low Carbon, has announced construction of 3 new large solar farms in Essex, Derbyshire and Buckinghamshire. Construction in Buckinghamshire will begin immediately. Once complete the facility will provide clean power to more than 7300 homes. Capacity of this site will be 23.4MW. Work on the 28.8MW Derbyshire and 23MW Essex locations will begin in the early new year – 2023. Similar installations are being constructed across every continent.

WIND ENERGY

Renewable wind energy is created when wind turbines are pushed by natural currents of air which is then converted into electricity via a generator. Current UK direction of onshore wind energy is convoluted. At present there is a ban on installing new onshore wind farms inside the UK. However, some media outlets report that the ban is lifted, others maintain the ban is still in effect. Offshore wind farm capacity is being expanded to meet future demand. There are several new installations being constructed inside UK and Irish waters.

Offshore wind facilities under construction and due to begin operations. Amongst the new sites to be introduced is the Dogger Bank Wind Farm off the coast of Yorkshire, Northeast England which will begin operations in 2025. £8.27 billion has been invested into this project and is a joint venture undertaken by SSE Renewables, Equinor and Eni Plenitude.

WAVE ENERGY

Wave energy is created once captured kinetic energy gathered by tidal movements pushes a turbine, which in turn produces electricity. Wave and wind energy rely on the same concept of utilising kinetic energy to generate power. Wave energy is considered 100% carbon neutral. Wave energy is expensive to produce and maintain but is also effective. UK policy adjustments in market and planning legislation could see wave power become expanded to meet future demand.

Further on-land construction work is continuing on the £35 million Holy Island Tidal Energy Scheme, in North Wales. 35 sq km of seabed will be used to generate as much as 240MW of clean tidal electricity, enough to power 180,000 domestic properties.

rDME

Renewable DiMethyl Ether – known as rDME – is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for quick and long-term sustainable production. rDME contains a similar chemical composition to Butane and propane and can be mixed with LPG in existing appliances to continue product operations.

rDME combusts cleanly and releases no “soot” emissions. It has many fuel properties that make it easily used in sites and appliances currently using diesel as a fuel. It has a very high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines.

Future capacity of rDME is set to rise sharply, further increasing the likelihood of rDME being introduced nationally at some stage soon. A demonstration plant is to be opened later this year, whist the first operational commercial site manufacturing rDME will be on-line in 2024 in Teesside.

LGP & BioLPG

LPG (Liquefied Petroleum Gas) is a low carbon fuel source that is supplied in two forms – propane and butane. BioLPG is 100% carbon neutral and produced through renewable feedstocks such as plant and vegetable waste. Both are considered future forms of carbon friendly energy.

LPG producers see a role for Bio-LPG in the future whether that be blended with LPG or BioLPG. The fuel can be theoretically drop in, meaning limited disruption and user familiarity. Companies have invested over £260 million to date in developing clean liquid gases, including bioLPG and rDME to market. During the transition to renewable liquid gases LPG will remain a valuable part of the low carbon energy mix.

As economies and industry attempt to decarbonise fuel supplies, demand for LPG and BioLPG will rise. Legislation amendments introduced by the US, EU and Japan could see both demand and produced volume of BioLPG increase.

NUCLEAR ENERGY

Nuclear energy occurs when a reaction from either uranium or plutonium is stimulated to generate electricity. The UK government is keen to expand nuclear capacity.

As of writing, it has been confirmed that the UK government will inject £700 million of taxpayer’s money in developing Sizewell C nuclear power plant. Doing so will provide 6 million homes with low carbon electricity for more than 50 years and strengthen national energy security.

HYDROGEN

Hydrogen is produced in various forms signalled by a spectrum of assorted colours: blue, green, pink, brown, grey, yellow and turquoise.

 

  • Blue hydrogen is formed once natural gas is heated with steam in a process called Steam Methene Reforming (SMR). Hydrogen and carbon dioxide are created as a result meaning that emissions must be captured and stored for blue hydrogen to become a low carbon fuel source.
  • Grey hydrogen uses Steam Methene Reforming without capturing any emissions.
  • Green hydrogen occurs once water molecules are split into oxygen and hydrogen using renewable energy to power an electrolyser which sits in a water basin. Green hydrogen is considered 100% carbon neutral and is regarded as a source of future clean energy.
  • Pink hydrogen is created through nuclear powered electrolysis whilst yellow hydrogen is produced through solar powered electrolysis.
  • Turquoise hydrogen is made using a process called methane pyrolysis which produces hydrogen and solid carbon.

 

An extensive list of major international energy companies, such as BP and Equinor has announced various projects costing billons that explore the introduction of hydrogen as a major contributor towards future global energy needs. Spanish renewable energy company Iberdrola are planning to develop a green hydrogen production facility at the UK’s largest port in Felixstowe. Iberdrola is prepared to invest £150 million in the project which is expected to be operational in 2026.

Closer to home the UK issued its Hydrogen strategy in 2021, with the objective of achieving 10GW of Low Carbon Hydrogen by 2030. The strategy is also seeing rapid developments in pilot schemes using 100% hydrogen across the UK.

Cost of living causing consumers to think again about retrofitting

 

RICS and YouGov survey shows homes therefore less likely to be able to cope with climate impacts or to mitigate rising energy costs

The cost of living crisis, has cast new doubt on the progress towards the United Kingdom’s Net-Zero ambition. Previous research from RICS* had found that homeowners were citing cost of retrofitting as a barrier, but despite new policy measures, new research from RICS and YouGov shows that consumers are now concerned about paying for the cost of living above upgrading their homes.

Retrofitting has obvious benefits, such as being able to maintain a constant temperature in the home, as well as increasing the desirability of your property – the December 2019 Residential Market Survey*, prior to the energy crisis, cited almost two thirds of the survey’s respondents believed that the willingness to pay for energy efficient homes would rise in the next three years.

However, the latest consumer research from RICS and YouGov shows that homeowners are unsurprisingly looking to concentrate spending on escalating household costs.

The new research backs up previous calls made by the institution in 2020 for more policy measures to incentivise industry and consumers to retrofit the UK housing stock. The research found that while 34% of homeowners said they would invest in green technology to lower bills in the future, 45% would be focusing on using any savings to pay for their existing living expenses, meaning more incentives and cheaper options must be made available if the country is to stay on track to meet target and green 15million properties*.

This latest research follows the RICS January 2020 Residential Market Survey* where members operating in the residential sales and lettings market stated that without strong market driven incentives, regulation was the policy lever with the greatest potential to improve energy efficiency outcomes. Alternatively, a tax policy could achieve a similar effect through a mix of stamp duty and a reduction of VAT on home improvements.

Currently, the Government’s ambition to hit Net-Zero carbon emissions requires significant numbers of private homeowners to retrofit their properties to make them greener.

51% who confirmed they hadn’t already installed new energy saving measures in their homes but would know how to, said it was because of the costs involved. And of the same group, even those who would consider it to make their home more attractive to prospective buyers, 40% said they’d only consider spending around £1000 to £5000 on energy improvements, which could pay for some solar panels** but wouldn’t cover the heat-pump.

As the cost of living continues to consume more household finances, measures are needed to avoid many properties failing to meet targets and becoming un-mortgageable. To review the potential impact that failure to support consumers would have on the housing market, most homeowners (55%) would consider installing energy saving schemes if they knew it would make their property more attractive when it came to selling up. With figures from Rightmove showing that greener homes can attract a higher premium, properties need more than an EPC assessment to help inform decisions**.

As EPCs aren’t the best measure for all properties, as some listed buildings can’t have triple glazing for example, RICS is recommending and working with lenders and government to look into ‘Retrofit Surveys’ which would enlist the expertise of a professional – such as a building surveyor- to provide detailed advice on what technologies homeowners could install to help inform their decisions. This is supported with 77% of homeowners saying they’d find this advice helpful when thinking of buying a new home.

Sam Rees, Senior Public Affairs Officer at RICS, said:

“The retrofitting of millions of UK homes will be essential to helping to meet our net zero ambitions, however homeowners’ immediate concerns are understandably with the rising cost of living, especially their energy bills. It is important to recognise that retrofitting and the cost of living are not mutually exclusive issues.

“A suitably retrofitted, low-carbon home can help with the long-term challenges of the cost of living and reducing high levels of energy consumption. Achieving this however is not cheap. With the UK Government giving financial support to homeowners to support them with rising energy prices, RICS is calling on the government to extend this support and provide additional financial incentives to homeowners to encourage retrofitting and ultimately helping to tackle the cause of high energy usage.

“Before any significant investment is made on retrofit measures, RICS urges homeowners and the government to ensure a retrofit assessment is undertaken on the property first – ensuring that no unintended consequences occur such as overheating or increased energy demand. This is critical to protecting consumers and RICS is undertaking significant research to support such assessments.”

The top energy saving measures homeowners who know how to make their home more environmentally friendly said they already had installed in their property were:

Double or triple glazed windows – 71%
Energy-efficient lighting – 69%
Loft/cavity wall insultation – 63%
Energy efficient appliances – 52%
Solar panels – 17%
Air source heat pumps 5%
Geothermal heating – 2%

All figures, unless otherwise stated, are from YouGov Plc. Total sample size was 4357 adults of which 2776 are homeowners. Fieldwork was undertaken between 31st May – 3rd June 2022. The survey was carried out online. The figures have been weighted and are representative of all GB adults (aged 18+).

** Solar panels typically cost between £2,900 and £6,700 according to the Energy Saving’s Trust.

Home energy improvements which cut emissions and bills for over 300,000 low-income families every year will only be done by trusted tradesmen, under new government plans.

The government’s new quality scheme, delivered by ‘TrustMark’, will increase protection for low-income and vulnerable households, helped with free energy-saving measures like insulation and new boilers, under the Energy Company Obligation (ECO).

Emissions from buildings account for nearly 25% of overall carbon emissions, which the government is committed to reducing. Just weeks ago, the UK became the first G7 economy to put into law a commitment that Britain will reach net zero greenhouse gas emission economy by 2050.

Energy and Clean Growth Minister Chris Skidmore, said “Driving up the energy efficiency of Britain’s homes is key to us reducing emissions from households, saving people money on their bills as we legislate to become a net zero emissions economy and end our contribution to global warming entirely.

“This new scheme will guarantee low-income households the peace of mind that workmen installing energy efficiency measures in their homes are trusted tradesmen.”

Around 15% of households take an energy efficiency measure each year, with over one million installing additional or replacement loft insulation and over one million upgrading to double glazed windows.

The new ‘Each Home Counts’ quality mark will help reassure households having work done on their homes that the companies have met the appropriate standards for installing insulation and new central heating systems in their homes.

Consumers who want energy efficiency measures installed on their own homes will be able to search the TrustMark website for trusted and certified tradesmen, checking their installers are recognised before they start work on their homes.

The new mark builds on the well-established government-endorsed ‘TrustMark’ scheme, which vets businesses. It ensures they meet industry standards, have good technical competence and trading practices, and have a commitment to providing good customer service.

Customers can already access free and impartial advice on reducing their energy bills, making their homes warmer and planning green home improvements from Simple Energy Advice.

Energy efficiency industry is worth £20.3 billion in Great Britain, employing nearly 150,000 and selling exports worth over £1 billion every year.

With government legislating for net-zero by 2050, what does this mean for UK energy markets and business models?

Getting to net-zero will require economy-wide changes that extend well beyond the energy system, leading to rapid and unprecedented change in all aspects of society.

Research published today by the UK Energy Research Centre shines a light on the level of disruption that could be required by some sectors to meet net-zero targets.

With many businesses making strong commitments to a net-zero carbon future, the report highlights the stark future facing specific sectors. Some will need to make fundamental change to their business models and operating practices, whilst others could be required to phase out core assets. Government may need to play a role in purposefully disrupting specific sectors to ensure the move away from high carbon business models, facilitating the transition a zero-carbon economy.

Sector specific impacts

The in-depth analysis presented in ‘Disrupting the UK energy systems: causes, impacts and policy implications’ focuses on four key areas of the economy, highlighting how they may need to change to remain competitive and meet future carbon targets.

Heat: All approaches for heat decarbonisation are potentially disruptive, with policymakers favouring those that are less disruptive to consumers. Since it is unlikely that rapid deployment of low carbon heating will be driven by consumers or the energy industry, significant policy and governance interventions will be needed to drive the sustainable heat transformation.

Transport: Following the ‘Road to Zero’ pathway for road transport is unlikely to be disruptive, but it is not enough to meet our climate change targets. The stricter targets for phasing out conventional vehicles that will be required will lead to some disruption. Vehicle manufacturers, the maintenance and repair sector and the Treasury may all feel the strain.

Electricity: Strategies of the Big 6 energy companies have changed considerably in recent years, with varying degrees of disruption to their traditional business model. It remains to be seen whether they will be able to continue to adapt to rapid change – or be overtaken by new entrants.

Construction: To deliver low-carbon building performance will require disruptive changes to the way the construction sector operates. With new-build accounting for less than 1% of the total stock, major reductions in energy demand will need to come through retrofit of existing buildings.

The report identifies how policy makers plan for disruptions to existing systems. With the right tools and with a flexible and adaptive approach to policy implementation, decision makers can better respond to unexpected consequences and ensure delivery of key policy objectives.

Prof Jim Watson, UKERC Director and Professor of Energy Policy, UCL said “The move to legislate for net-zero is welcome progress, but we need economy-wide action to make this a reality.
This includes policies that deliberately disrupt established markets and business models in some sectors – and address any negative impacts.”

Prof Jillian Anable, UKERC Co-Director and Professor of Transport and Energy, University of Leeds added “The UK transport sector is nearly 100% fuelled by fossil fuels, with only tiny niches of electrified and bio-fuelled vehicles.

Whilst politically challenging, the sector can only hope to reach ‘net-zero’ through whole-scale change that involves reducing hyper-mobility and fuel switching. This will lead to disruption to actors, global networks, governance and lifestyles.”
