Why the UK needs to clean up its power sector by 2035

This post is by Ben Westerman, freelance policy adviser at Green Alliance.

The International Energy Agency (IEA) recently released its roadmap on reaching a net zero global energy system by 2050. Its message was clear: current pledges by governments around the world fall well short of what is needed to reduce emissions fast enough to reach net zero by 2050 and prevent global temperatures rising above one and a half degrees.

Pursuing the hydrogen economy as a climate solution will be a big mistake

This post is by David Cebon, professor of mechanical engineering at Cambridge University.

There has been a lot of talk about hydrogen in the past year or two. Advocates for a ‘hydrogen economy’ make claims about how ‘green hydrogen’ (made by electrolysing pure water with renewable electricity) will power future energy systems. The idea is that green hydrogen will be generated at times of day when renewable electricity is cheap (ie when supply is high and demand is low). The hydrogen gas will be stored in underground salt caverns until needed and then either converted back into electricity and injected into the electricity grid or piped around the country to heat buildings and fuel lorries.

Five expert insights on Brexit and energy

1331541437_ca6433862f_bOn 13 November, we invited the EU’s former director general of DG Energy, Sir Philip Lowe, to speak to a small specialist audience about the likely impacts of Brexit on energy and climate policy. Sir Philip, who was in post from 2010 to 2014, is well qualified to comment: he has deep expertise across key EU institutions and is currently chair of the World Energy Council’s energy trilemma initiative. The meeting sparked interesting conversations, including around Sir Philip’s recent publication, Brexit and energy. This post reports the main insights from our discussion.  Read more

What Dieter Helm’s review and the industrial strategy might miss

2143563816_27d654bf2b_b.jpgNot all of the ten ‘pillars’ of the industrial strategy green paper will make it into the white paper expected by the end of this year.  Civil servants working on the final strategy say the innovation, skills, place, business and infrastructure pillars are the ones likely to remain and the content of the affordable energy and clean growth pillar will be embedded across the strategy.   If that can be done well it will better than having a standalone chapter, but if it is done badly, it will be a disaster for the UK’s low carbon transition.

Now renewables are the cheapest source of energy, it’s time to rethink UK policy

cleanThe results of the yesterday’s government auction for renewables procurement has taken the entire energy sector by surprise. Clearing 860 MW at £75/MWh in 2021 and 2.3 GW at £57/MWh in 2022, it revealed that the cost of offshore wind has dropped by 65 per cent in under five years. This result comes close on the heels of a report from Renewable UK, highlighting that the UK’s offshore wind industry has now increased its domestic content to 48 per cent and is in the process is providing almost 20,000 direct and indirect jobs. Heavy investment during the industry’s nascent years has yielded tremendous results and the UK can confidently stake its claim to be the global leader in offshore wind.

Why Big Energy Saving Week didn’t save much energy

StromzählerThis post is by Dustin Benton and Amy Mount.

After a summer of wiping the slate clean, the one remaining certainty about the government’s attitude to UK energy policy is that it is committed to minimising cost. This was the aim behind last week’s Big Energy Saving Week, the core ‘switch and save’ message being that customers can save money by switching suppliers. This was odd, given that switching has nothing to do with saving energy.

Gas from Norway, coal from Russia: eight graphs on the UK energy system

Gas tank and silosThis post by Robin Webster was first published on The Carbon Brief

The UK’s dependence on energy imports has increased to its highest level since 1976, according to statistics released by the Department for Energy and Climate Change (DECC). Here’s the story of the UK’s dependence on imported fuels in eight graphs.

DECC released the data at the end of March, about a month after the chief executive of energy regulator Ofgem warned that the country’s dependence on imported fuels could drive up consumer energy bills. Read more

A second chance for CCS?

This post is by Dustin Benton, senior policy adviser at Green Alliance. A version of this article originally appeared on the Guardian website.

Carbon capture and storage promises all the ease of continued use of fossil fuels without the carbon emissions. The UK should be a leader in its development. It has all the advantages of good geology, industry expertise, and public support, but as the National Audit Office reported two weeks ago, our demonstration programme has been plagued by delays, putting the whole programme back by half a decade. This has happened because the policy supporting CCS is based on outdated assumptions. Read more
