Hinkley Point C delayed – meanwhile renewable energy outperforms coal in new statistics

Controversial plans to construct a nuclear power plant in the UK have been delayed following the government postponing any final decision until early autumn. Meanwhile, new official UK electricity statistics indicate that renewable technology is currently outperforming coal in terms of energy generation.

Prior to today’s announcement that the project would be delayed, French firm EDF were financing the majority of the £18bn Hinkley Point C project in Somerset, and final contracts were due to be signed this week.

However, Business Secretary Greg Clark has now said that the government will have to “consider carefully” before backing the original plans.

The project has raised serious concern over both environmental impact and ever-rising costs, which make it a costly carbuncle rather than a real asset to Britain. There are also questions being raised about the fact that the plant is being built by foreign governments. For example, around 30% of the £18bn cost is currently being provided by Chinese investors.

Stop Hinkley Spokesperson Allan Jeffery commented “Now even the financial press says Hinkley Point C has become a laughing stock.

“The cost keeps rising while the cost of renewables is falling rapidly, and the potential to make savings with energy efficiency is huge. We could replace Hinkley much more quickly and cheaply without the safety fears and without producing dangerous waste we don’t know what to do with.”

Renewables

In other energy news, the Government’s new annual energy statistics show that renewable energy sources are replacing coal as mainstream technologies generating power for British homes, offices and factories.

Today’s figures confirm that 25% of the UK’s electricity was generated from renewables last year – an increase of 29% on 2014. Nearly half of this (48%) came from wind power alone. 1 in 8 units of electricity generated in the UK came from wind.

In comparison, coal generated 22% of the country’s electricity – down from 30% in 2014.

RenewableUK’s Deputy Chief Executive Maf Smith said “The Government took the right decision when it announced the phasing out of coal. Now we can see renewable energy filling the gap, replacing old technology with new. 2015 was the first year that renewables outperformed coal.

“A quarter of Britain’s power is now coming from wind, wave and tidal power and other renewable energy sources. Renewables are now part of our energy mainstream, helping us modernise the way we keep the lights on by building new infrastructure for the generations to come.”

The contribution of offshore wind grew by 30% in 2015, while onshore wind grew by 23%. The Department for Business, Energy and Industrial Strategy, which published the figures, said this was due to increases in capacity, load factors and higher wind speeds.

The Government’s latest poll on the public’s views on energy, the Public Attitudes Tracking Survey, was also published today. It showed that 76% of people support renewable energy. 70% of people also said renewable projects provide economic benefits to the UK.

Wind turbines set to reach mega heights with new techniques

Wind turbine towers are set to reach heights of up to 170m with new construction techniques and materials, according to wind power engineering specialists K2 Management. Tower heights have grown steadily over the last decade as operators seek stronger wind speeds higher up in the atmosphere.

Based on work with various clients across the globe, K2 Management believes new technology developments like modular concrete structures mean turbine heights are likely to soar to up to 170m in the coming years – higher than London’s ‘Gherkin’, and almost as high as the Eiffel Tower. This compares to the tallest towers of 150m at present. There has been a 48% increase in average hub height since 1999, and based on its experience in the industry and its partnerships, K2 Management has insight on how to manufacture hybrid tower concepts up to 170m.

According to K2 Management wind resource experts, a 3 MW turbine located in a forest area for example, with an average wind speed of 6 meters per second, will meet 13 percent more wind speed if the turbine height doubled from 70 to 140 meters. Annual energy yield prediction would increase by almost 30 percent because of less surface aerodynamic drag and the viscosity of the air.

Therefore, going up to 170 meters from 70 meters will boost energy yield prediction by 35 percent on average. The more complex the terrain – for instance forests, hills, mountain, buildings – the larger the impact is in using taller turbine towers.

K2 Management CEO Henrik Stamer says “170m towers could become a common sight in the near future in markets like the USA and Germany as part of a new renewable skyline. We expect to see more of these mega designs as we help our clients get the most out of their wind projects.”

Through its network of experts across the globe, K2 Management possesses a unique vantage point overlooking the wind industry, allowing for a view into emerging trends. The Company is able to draw on this wide breadth of experience to identify ways of making wind projects more efficient.

Stamer adds: “As a company that is at the global cutting edge of technology we are helping push the limits of the wind industry in terms of power generation efficiency, cost-effectiveness and return on investment; and these new mega wind turbine towers are a case in point.”

World’s largest concentrated solar plant opened in Morocco

Morocco has launched the first phase of the largest concentrated solar power (CSP) plant in the world. When fully operational, the plant will produce enough energy for more than one million Moroccan households.

Inaugurated officially by His Majesty Mohammed VI of Morocco, the solar plant underlines the country’s determination to reduce dependence on fossil fuels, use more renewable energy, and move towards low carbon development.

The three-plant Noor-Ouarzazate CSP complex called NOORo expects to achieve over 500 megawatts (MW) installed capacity, ultimately supplying power to 1.1 million Moroccans by 2018. It is estimated that the plant will reduce the country’s energy dependence by about 2 and half million tons of oil, while also lowering carbon emissions by 760,000 tons per year.

Concentrated solar power is such a promising technology that the International Energy Agency estimates that up to 11 percent of the world’s electricity generation in 2050 could come from CSP. This is especially true in the Middle East and North Africa, a region with abundant solar resources and high hopes of eventually helping to meet the E.U.’s demand for energy.

“With this bold step toward a clean energy future, Morocco is pioneering a greener development and developing a cutting edge solar technology,” said Marie Francoise Marie-Nelly, World Bank Country Director for the Maghreb, “the returns on this investment will be significant for the country and its people, by enhancing energy security, creating a cleaner environment, and encouraging new industries and job creation.”

Despite the potential of CSP, relatively high technology costs, when compared to fossil fuel alternatives, deter utilities from investing. Concessional and public financing were key to lift this project off the ground. The Moroccan Agency for Solar Energy, the government agency focused on the country’s solar ambitions, secured over $3 billion needed for the Noor-Ouarzazate complex from the African Development Bank (AfDB), the Climate Investment Funds (CIF), European financing institutions and the World Bank.

“This launch shows that the low-cost, long-term financing provided by the CIF can serve as the spark that attracts the public and private investments needed to build massive CSP production facilities at an attractive cost for countries interested in developing solar energy,” said Mafalda Duarte, Head of the Climate Investment Funds.

Trailblazing projects on the African continent, like the Noor solar plant, are proving the performance of CSP. As well as the environmental benefits, the plant results in new, local jobs, and can lead to a high-performing sustainable energy economic sector for Morocco.

Yacine Fal, AfDB resident representative in Morocco, said “Noor solar complex is part of the innovative operations of AfDB in the energy sector in terms of financing and technology. It stands to serve as an example for Africa and the world about how to create effective pathways to greener and more inclusive economies through renewable energy”.

Green Gas plant to inject £60 million into local economy

Britain’s leading green energy company, Ecotricity, has submitted a planning application for a Green Gas Mill at Sparsholt College – a partnership that will inject £60 million into the local economy.

As part of the unique partnership, Ecotricity will finance and build the Green Gas Mill, with an initial £10 million investment, and will also help fund the development of a renewable energy centre, where the college can train the workforce necessary to support the green gas revolution coming to Britain.

Ecotricity introduced the concept of making green gas from grass in Britain early last year[i], and if the company’s application to Winchester City Council is accepted, the Green Gas Mill will pump £3 million into the local economy every year for the twenty years of its operation.

Dale Vince, Ecotricity founder, said: “We have to stop burning fossil fuels, and green gas will play a big part in helping us to achieve that in Britain – it’s good for our economy, because we’ll no longer need to import those expensive fossil fuels; it’s good for the environment, because it’s carbon neutral and creates new wildlife habitats; and it’s good for farmers, because it allows them to diversify, rely less on farming livestock, and build a more sustainable future.

“The world signed up to the limiting temperature rise to well below 2 degrees C at the Paris Climate Conference last year – that included a long term goal of being carbon neutral after 2050 and eventually carbon negative, which means taking more carbon out of the atmosphere than we put in. They’re big ambitions – and green gas is essential to that vision.

“Sparsholt is one of the first Green Gas Mills we’re looking to build in Britain – one of the first in what will be a green gas revolution in this country. And what’s particularly special is that, together with Sparsholt, we’ll be helping to train the green gas engineers Britain will need.”

The Sparsholt College Green Gas Mill, fuelled by locally harvested grass, could produce enough clean gas to power the equivalent of 4,000 homes every year.

Tim Jackson, Sparsholt College principal, said: “We’ve carried out public consultation over the past four months with local councils, farmers and residents – and the feedback has been a mix of those who are very positive to those with concerns about the impact on local roads and the visual landscape.

“I am pleased to say that we were able to provide facts and explanations to address most of the concerns and look forward to responding to more of those as these arise.

“The Green Gas Mill is the next step on the journey towards Sparsholt College developing our status as a ‘Centre for the Demonstration of Environmental Technologies’, which is being supported by Ecotricity and through a grant from the Enterprise M3 Local Enterprise Partnership.

“Creating our own green gas on site will massively cut our environmental impact and reduce our energy bills – which have made up an increasing portion of our budget over the past few years, money that could be better spent on educating our students.

“However, the fact we can share the financial and environmental benefits of this project with the local farming community is a massively positive outcome for the college.”

Up to eight specialist professional jobs will be created to run the Green Gas Mill, while the new supply contracts with farmers – providing the grass and rye feedstock required to supply the anaerobic digestion process – will also reinforce existing jobs.

Feedback from local residents has most frequently focused on concerns about extra traffic and the routes chosen to transport feedstock.

Tim continued: “We have addressed residents concerns in the planning application and can reassure people that the Green Gas Mill will only receive normal farm traffic such as tractors and trailers which are typical of the countryside.

“We will ensure deliveries don’t happen during peak traffic times, tractors stick to main roads wherever possible, do not go through Sparsholt village, and in fact even at the busiest times of year during harvest, feedstock movements would represent a very small proportion of existing college traffic and be well within the capacity of the highway network.

“The Green Gas Mill will be a key component in the College’s development of a Centre of Excellence that will produce specialist professionals to work for the green gas industry, training engineers, plant managers and technicians in what is a growth area across the agriculture, energy, waste, water and food processing sectors.”
