As part of a study of how a 100 per cent renewable energy system in the UK could work academics from UCL have found that EITHER doubling the amount of increasing international electricity interconnectors OR having one third overcapacity of renewable energy generating capacity will reduce the need for storage to support a 100 per cent renewable energy system for the UK by up to half. In a paper just published in the leading Applied Energy journal they say: ”we find that, compared to the reference scenario, increasing renewable capacity by 33%, or interconnections by 200%, can lower system storage capacity by up to 50%”. They also found that delivering heating through heat pumps is half the cost of delivering the same heating using green hydrogen.
Drunk on the latest fossil fuel energy crisis, the UK Government has handed the British public a giant nuclear hangover that will leave the country scrabbling for renewable energy solutions.
Boris Johnson has promised 40 GW of offshore wind by the end of the decade, which, when added to other renewable energy sources, will generate over three-quarters of current levels of UK electricity consumption. But this growth could be threatened by the nuked-up knee jerk reaction to the current natural gas price crisis that will plunge the energy budget into a massive deficit and leave the electricity system dangerously unbalanced. After fossil fuel prices subside back towards their more usual levels, this will constitute a giant hangover.
Amidst a global shortfall of gas supplies in relation to demand (and a global increase in gas prices) the anti-renewables lobbies are busy blaming a lack of wind and solar (wot solar too?) for the soaring energy prices. It’s nonsense of course to pin the blame on renewables for a combination of a global oil and gas crisis and the UK’s unique market vulnerability to natural gas supply squeezes on renewables, but that’s precisely what is happening. The truth is we’d be much more secure and greener with a much higher proportion of energy coming from renewables backed up with a revived storage network that successive UK Governments have allowed to run down.
As coal-fired electricity production started up yesterday for the first time in months to fill the gap on a low wind day the cheapest solution – investing in more solar, wind and also storage capacity – was being widely ignored. Yet that solution would be many times cheaper than investing in Sizewell C, which was the solution being widely touted. A big spike in wholesale power prices (that won’t last anyway) is being used to justify pouring many billions of taxpayers money down a nuclear black hole.
The Government’s newly published hydrogen strategy is looking like a plan to protect the gas industry. It will, in effect if not motivation, be mainly concerned with keeping the supply of unmitigated natural gas flowing in the UK under the guise of promoting ‘blue’ hydrogen.
Windfarms are being delayed and even operating ones forced to shut down sometimes because of delays in securing planning permission for electricity interconnectors. So could green hydrogen production be a solution to this problem? The hydrogen could be produced and used in systems that avoid the need to build interconnectors for the windfarms. The problem of delays in interconnectors is biggest in Germany, but it is also affecting the UK.
A gang of so called climate cost sceptics on the Tory backbenches are busy spreading rubbish about the allegedly high cost of a low carbon energy programme. In reality the most effective measures, including heat pumps and electric cars, will turn out to be very cheap and the cost of making sure it happens will be very low. Meanwhile the big fossil fuel companies are conniving with the climate sceptics by pretending to be in favour of low carbon policies. They do this by advocating the most expensive means of doing them and then they cynically expect the public to turn against the programme.
The Government is likely to become responsible for a huge bill for building Hinkley C power station. This is despite an insistence by the UK Government since they signed a deal with EDF to build Hinkley C in 2012 that electricity consumers will not have to pay for cost overruns for the project. Yet it is now looking increasingly likely that this will end up being the case. When the deal was signed in 2012 the Government agreed to pay a much higher than expected £92.50 per MWh (in 2012 prices), this price to be paid by consumers in their electricity bills (over twice the price given to recent offshore wind projects).
Professor Christian Breyer of LUT University in Finland and Jonathon Porritt will be speaking at a webinar on Friday September 3rd (noon start) on the subject of ‘100 per cent renewable energy in Europe’. This is in support of the effort to raise funds for the 100 per cent renewable energy model for the UK which is being organised by 100percentrenewableuk.
Please donate to the fund to pay for the model to be done here! We still have a long way to go to pay for the study to be done!
After an introduction by Jonathon Porritt, Professor Beyer will talk about ‘100 per cent renewable energy in Europe’. Then he will answer some questions on the subject. After then we shall conduct a fundraising auction for the signed copy of Jonathon Porritt’s book! Jonathon Porritt is founder of ‘Forum for the Future’ and is perhaps the leading British author on green politics. His latest book is called ‘Hope in Hell’.
Christian Breyer is leading the team that has been chosen by 100percentrenwable uk to do the 100percent renewableuk model.

There’s been a story circulating recently about how Orsted’s plans for a big offshore wind park are clashing with BP’s plans to test under-sea storage of carbon dioxide. Big oil looks like it might take precedence over offshore wind. But in reality, things are even worse than this. Big oil are grabbing the best undersea storage resources for disposal of carbon dioxide and depriving renewable energy of potentially vital hydrogen storage options.
There’s lots of information being pumped out by the anti-renewables lobby about how renewable energy causes great increases in the costs of upgrading electricity networks, but in fact there’s a lot of ways in which decentralised energy will actually REDUCE network costs. A recent study from California emphasizes how the cheapest path to clean energy is a mixture of large renewable energy projects and small decentralised renewables (mainly solar pv) linked to battery storage systems. Solar pv-battery systems can exist as a mixture of domestic systems and larger ground-mounted systems.
There isn’t yet a similar study for the UK (the big energy companies who fund these things won’t want the truth leaking out!), but there’s logic to suggest that much the same thing might be the case in the UK. Sure, the UK isn’t as sunny as California, although in winter there’s a lot of wind power. But in any case the untold secret of a decentralised solar-plus-battery system is that the batteries will soak up electricity produced from whatever sources so as to even out the pressures on the electricity network. By reducing pressure on the electricity network both transmission and distribution network costs can be reduced.
Even-handed analysis of data from Germany and the UK indicates that it is still easily possible to dramatically reduce carbon emissions whilst greatly reducing the amount of energy coming from nuclear power.
One thing not usually appreciated in the arguments about the impact of nuclear power plant retirements in Germany is that in reality much the same process has occurred, for different reasons, in the UK. In both Germany and the UK the falling proportion of electricity coming from nuclear power has gone along with dramatic reductions in carbon emissions from electricity in both countries.
The Government is discouraging the adoption of heat pumps through the very important ‘Energy Performance Certificate’ (EPC) system. The EPC system shows energy consumption for particular buildings and gives advice on how to reduce it. It is legally essential when selling properties. Incredibly, even when a property is entirely heated using ‘resistance’ electricity, and therefore especially suitable for heat pumps, the standard advice given for energy improvements fails to mention the most important single measure which is likely to be the conversion of the heating system to a heat pump. Various other piecemeal measures will be selected under the EPC system, but heat pumps are not explicitly promoted.
There is a surge in capacity of onshore wind and solar projects with planning consent in anticipation of more Government-backed contracts being available later this year.
With public attention focussed on offshore wind the increasing amounts of onshore wind and solar projects awaiting commercial opportunities are being ignored. Yet (on top of those projects already under construction) already there is enough renewable energy projects with planning consent to supply over 3 per cent of UK electricity generation.
