Electricity

Energy storage has long been regarded as something close to a holy grail. Of course, there are ways of storing some forms of energy – using pumped water or compressed air for instance. There are conventional batteries – and there have been advances in their capacity over the last few years. But the search for storage systems which are simultaneously economic and practical for use at scale in the modern energy market has long been a source of frustration.

Recent advances made by scientists in the US suggest, however, that real progress is now being made and that major breakthroughs are close. The whole of the energy sector should be watching because any such breakthrough could transform the economics of the whole industry. Read more

The subtle redesign of Germany energy policy agreed by the government in Berlin last week sends some important signals not for the German market but for the rest of Europe. Far from damaging the renewables business the move could be the salvation of the sector. Other countries, the UK included would do well to adopt similar measures. This would be the most effective way of responding to the urgency expressed in the latest IPCC report. Read more

The full-scale competition review of the UK’s energy market which will be announced later this week is a challenge the industry should welcome. The inquiry will absorb a huge amount of time and effort over the next year but it offers the chance both for the industry to clear its name by removing the cloud of public suspicion over pricing policies and simultaneously for individual companies to examine their own strategic positioning in a market which is changing rapidly.

Of course, the competition review will add to uncertainty and will reinforce the reluctance to invest in new generating capacity, which is already evident, but the sense of doubt will exist in any case, and the review may help to produce some longer-term clarity. In the short term the government will have to find a new mechanism to ensure that supply is adequate to meet demand – and doing so with an expensive plan for emergency electricity supplies. But that is a separate issue from this fundamental analysis Read more

George Osborne in his Budget speech on Wednesday talked, correctly, about US industrial energy costs being half those of the UK. The situation has deteriorated rapidly over the past five years. His proposed response is worth quoting directly:

“We need to cut our energy costs. We’re going to do this by investing in new sources of energy: new nuclear power, renewables, and a shale gas revolution.”

This must be a speechwriter’s joke. A line written in where the content bears absolutely no relationship to reality. New nuclear at £92.50 a megawatt hour will double the current wholesale price of electricity. New offshore wind on the Department of Energy & Climate Change’s own figures, which many feel are too low, will cost more than £120/Mwhr. These are not secret figures. They are well known in the Treasury, as is the risk of generating capacity failing to meet demand. There was no mention of that little problem. Read more

This week’s meeting of the European Council in Brussels will be a significant test of the EU’s relevance and unity in dealing with the consequences of what is happening in Ukraine. Over the years as indigenous production, especially of gas, has declined Europe has allowed itself to become more and more dependent on Russian supplies. Last year Europe imported 160bn cubic metres of gas – a quarter of its total requirements. Even if Russia were a normal country that level of dependency would look high. Now, with Russia ignoring the strong messages from the German and American governments urging restraint in Ukraine, and massing troops on the border, reducing that degree of dependence is a matter of urgency. Read more
