Carbon Capture Plan Collapses – A Set Back or an Opportunity?

The Government's plans for carbon capture and storage (CCS) were dealt a major blow yesterday with the collapse of plans to fit CCS equipment to the Longannet power station in Fife. The Government has commitment to fund up to four CCS demonstration schemes, however the collapse of the Longannet scheme means it will now have to start from scratch - there are no other potential CCS schemes currently under consideration.

Yesterday's announcement was prompted by ballooning costs for the scheme. The Government had committed £1 billion of funding for the project, but the length of the pipeline needed to transport carbon dioxide from the plant to undersea reservoirs meant that the project would cost at least £1.3 billion, prompting the plant's owner, Scottish and Southern Energy, to pull out.

The Government has clearly stated that it is the technical difficulties at the Longannet plant, rather than with CCS as a whole, that has made the scheme non-viable. However, there is no doubt that this is a serious blow to the Government's plans and delays the process of rolling out CCS by several years.

The Government often states that it is not in the business of picking technology winners, but plans for the transition to a low carbon economy (drawn up under the previous Government) do rely heavily on CCS to help de-carbonise the UK's electricity supply. A de-carbonised and expanded electricity supply can then be utilised in sectors currently dominated by fossil fuels such as space heating and transportation, hence the Government's strong support for battery electric cars (you read my views on these on page 9 of this magazine).

However, CCS is still a technology that is untested at an industrial scale and has little chance of ever being considered 'cheap'. A full scale rollout of CCS essentially involves the creation of a shadow energy industry to capture, transport and dispose of the unwanted carbon emissions. The construction and running costs of such a industry are likely of a similar magnitude to the fossil fuel industry it would shadow, costs that will have to be born by UK citizens and businesses either through fuel bills or taxation. Whilst costs can no doubt be reduced CCS will always be hugely more expensive than the cheap energy baseline – coal or oil fired generation without CCS.

Technologies such as solar, wind and, dare I say it, nuclear energy all start from a position of producing zero carbon emissions, and crucially have significant scope to reduce their cost through research and development and economies of scale. Unless the UK wants to be wedded to a future of expensive energy then perhaps the Government should take a chance and offer up the enormous £1 billion per plant that they've committed for CCS to research and development in a broader range of energy technologies. This would perhaps be a bigger gamble compared to plumping for CCS, but holds out the promise of cheaper low carbon energy in the longer term.

MPs Blast Government Over Air Pollution Failures

Parliamentary Select Committees are rarely kind to Governments. With a remit to scrutinise the Government's record they normally pick policy areas where heals are being dragged rather than shining examples of success. But even against this background accusing the Government of 'putting the health of the nation at risk' is quite strong stuff. This statement is contained in a new report from the Environmental Audit Committee (EAC), 'Air Quality: A Follow Up Report'. The document is a successor to the EAC's 2010 ' Air Quality ' report, a wide ranging examination of the previous Government's record on air quality. The new report is shorter and more focused, examining what's changed since the previous report was published and making suggestions for key policy changes. As with any select committee report the Committee invited submissions of evidence from organisations and individuals, in his case attracting 26 written submissions. They also heard in

The Green Deal - is it any good?

The Green Deal launched this week in a blaze of publicity, unfortunately much of it negative. The scheme has been the Conservative’s flagship home energy efficiency policy since before they even came to power, so the big question is: is it any good? The short answer is that it’s good for some, but not for others. At its heart the Green Deal is a loan scheme for energy efficiency and renewable energy measures, but rather than homeowners paying back the loan directly to the bank the repayments are made via a charge on their electricity bill. The two key innovations of the Green Deal are that the repayments should not exceed the anticipated savings on your energy bill (i.e. your bills will be lower afterwards, even with the loan repayments) and that the loan stays with the property rather than you (if you move the new owner takes over the repayments). The Green Deal is an attempt to address one of the big problems with some energy efficiency and renewable energy measures. Upg

Sunset for Solar Panel Subsidies

Subsidies for solar photovoltaic panels are set to be slashed after the Department for Energy and Climate Change (DECC) launched a consultation on halving the main ‘generation tariff’ available through the popular Feed in Tariffs (FiTs) scheme. The proposed cut will apply to new installations only: individuals and businesses who are already receiving the subsidy will continue to get the full rate. The Government’s reasoning for the proposed cut is a fall in the cost of the solar panels themselves. Whilst this is true, it is largely the result of a glut in the supply of solar panels which would be expected to reverse as the manufactures scale back production in response - the actual costs of producing them is little changed. Behind the scenes though the cuts reflect increasing nervousness by the Government around the impact of ‘green’ commitments on our fuel bills. The cuts may bring to an end a boom in solar installations where solar photovoltaic panels became the best investme
