Low Carbon Subsidies for All!

Through the queens speech the coalition government announced a series of energy market reforms, in the form of the energy bill, that they hope will provide an adrenaline boost to the flagging industry, mainly in the form of complex subsidies. However, as has been apparent with most announcements regarding the energy industry from the government, there are still large areas of policy shrouded in mystery.

The system the government is trying to implement works around low-carbon electricity (from renewable or nuclear sources) can sign long-term contracts to supply at a preferential rate, so effectively legislating against carbon emissions. While this on the face of things looks like a step in the right direction the head of climate change at WWF-UK had some harsh criticism of the legislation, while saying it was a step in the right direction he indicated that it did not nearly go far enough.

One significant implication of the legislation is that it will effectively subsidise the Nuclear Industry as it is a low carbon source of electricity, which is at odds with the coalition agreement, that there would be no state subsidies for nuclear power. Incentives have been shared across, what the government has been to classify as, low-carbon industries; though surely a worry is that the renewable industry will be stifled in the UK, compared against more established technologies.

If we take a look at the German Company Strabag’s development of serialised wind turbine installations, and the speed of that development, we can see what can be achieved focus is placed on renewable energy. This goes to highlight that while the renewable industry is growing in this country at a very healthy rate more can be achieved with greater support.

The Nuclear industry by its very nature is a slow developing beast with small evolutionary design changes targeted towards safety rather than taking revolutionary design steps. This approach being taken to ensure that we have the safest plants possible, as we are dealing with radiation sources after all. If we take a look at the development on the EPR plant at Flamenville in France we can see how slow Nuclear can progress.

The government is worried, and so should we all, about the impending likelihood of black outs and, with the nuclear renaissance faltering, needed to promote growth within the energy sector. With the energy bill they hope to achieve that, unfortunately as the bill seems to be lacking in detail in some areas and over complex in others, the likelihood of success is uncertain.

The future energy balance in the UK must be made up from a mixture of renewable and nuclear in order to be anywhere near the targets set for 2050 on reducing carbon emissions and we must develop a smart grid in order to deliver electricity to where it is needed. That is why clear direction is needed from the government on such issues and while the UK may not ever be a major contributor to global nuclear technology we still have the opportunity to be world leading in renewable/clean technology.

CCS a Panacea for Climate Change...

This week the UK government announced a new initiative to promote the development of Carbon Capture & Storage (CCS) technology, after the total flop of the last scheme. The CCS roadmap can be split into three distinct parts: the first provides research and development funding, the second grants for the construction of plants and the third funds the running costs, which makes this an attractive scheme for industries looking to develop CCS.

Heralded by the government and fossil fuel companies as a panacea for CO₂ reduction; they say it’ll enable polluting fossil fuel plants to run with ‘zero’ carbon emissions (an 80-90% reduction), a view many will question. Now I will try and answer some key questions: what are the merits of CSS, will it actually work on an industrial scale and what part does it have to play in reducing global warming and aiding theUK in meeting its 2020 and 2050 targets?

As you may know, the idea behind CCS technology in power generation is to enable the stripping of CO₂ from the emissions from fossil fuel fired power plants (pre or post combustion) and to then store it , normally very deep underground or under the sea. The technology behind CCS is largely unproven on an industrial scale and the storage component is an unknown element. The injection of CO₂, and essentially the storage of CO₂, has been used to prolong the life of oil wells in enhanced oil recovery but if this method of storage is stable is unknown.

What has to be remembered is that with CCS we are still producing vast quantities of CO² by burning non-renewable fossil fuels, it doesn’t reduce emissions we’re just storing them away. We do not know how reliable the storage of CO₂ is, and whether or not it will escape or dissipate and rise to the surface adding to global warming in the future. Also, it’s virtually impossible to measure the success of the storage solution and/or any CO₂ escape from deep sea storage. This is also not to mention the problems that may be caused to the pH level of the sea and the effects that it may have on sub-sea ecosystems.

Ok, so if there are so many uncertainties surrounding CCS, and potential pitfalls, what place should it have as one possible solution to reach our 2020 and 2050 emission targets? Well while I do not under any circumstance see this as a long term solution to reducing emissions, especially as we will run out of fossil fuels before long, I do think in the short term it does have a key part to play if we want to have any hope of achieving the targets set for 2020 and 2050 as we are woefully behind with our development of low carbon and renewable energy.

While this new scheme will be welcomed by investors and will aid in meeting the UK’s targets in reducing CO₂ emissions we all have to remember that it still involves burning a fast depleting finite resource where security of supply is a significant concern. CCS isn’t the solution to climate change, or the energy gap, but it may have a supporting role.
