From these requirements, and seeking to preserve a safe, government action is based on four pillars: energy conservation, increased use of renewables, nuclear fleet renewal and development patterns production of cleaner energy from fossil fuels.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">This last point is of course referring to technologies Capture and Storage (CCS). The United Kingdom was already planning to rely on such devices by linking them to central power generation from coal. Now, following an announcement by Chris Huhne, Minister of Energy and Climate Change, dated November 8, 2010, power plants fueled by natural gas are also concerned by the use of these technologies. This announcement is fully willing to give up important ways of generating electricity safe, clean and relatively inexpensive.<span id="more-11234"></span></p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">The program of the coalition government acknowledges the commitment of governments to support the construction of four demonstration facilities systems CCS on coal plants. After the general review of public spending, the government announced that 1 billion would be used to fund £ the first draft. The method of funding the other three demonstration projects, which could take the form of a tax dedicated to<strong> CCS technologies</strong>, will be decided in spring 2011. Initially, the demonstration program only to relate to the coal plants (including carbon dioxide emissions are about twice those of gas power plants: 800 400 gCO2/kWh gCO2/kWh cons), they are seeing by otherwise subject to very strict limitations on emissions (Emission Performance Standard). In practice these limitations, which must still be encrypted, will want a way to ban the construction of new coal plants that are not provided with facilities of CSC.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">The opening of this demonstration program to gas power plants followed the advice given to government by the Committee on Climate Change (CCC committee on climate change) through a letter addressed to Chris Huhne in June 2010. In this document, the committee recalled that the area of energy production had to adopt a model significantly less carbon emitter by 2030, otherwise the 2050 targets set in the Climate Change Act (emissions Greenhouse gas emissions reduced by 80% between 1990 and 2050) would be more realistic. In this context, they called on the government to adopt a more coherent and therefore work on the adaptation of CCS technology for gas plants now. Their position did not however claim to the same requirements as compared to emissions for coal plants, the need for conventional gas plants is obvious to maintain the security of energy supply during the transition from UK towards a system of energy production cleaner.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">Various demonstration projects of CCS technology could potentially be fired plants to coal or gas. The government’s decision, if it follows the opinion of the CCC, is also based on an analysis of expected benefits of this new approach. Indeed, the Minister of Energy and Climate Change expects that this decision confirms the leading position occupied by the United Kingdom in the development of technologies to capture, transport and storage.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">The measure announced by the government does not, however, gas plants and coal on an equal footing. Chris Huhne did not actually intend to apply the same requirements in terms of emissions for these two modes of energy production, and what the short or medium term. The recommendation of CCC providing that the new gas power plants built after 2020 should be equipped with CCS systems in particular has not been followed.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">The CCC has nonetheless welcomed the announcement, which was not the case of large companies in the energy sector as RWE and E. ON They fear that, despite the insistence of the Minister on the fact that it is not intended to limit emissions from gas plants, he almost expected the establishment of such regulations in the future. For them, the uncertainty on this point could, pushing investors constitute an obstacle to building new power generating electricity from natural gas. The country’s energy supply would be at risk because, as mentioned above, gas plants are expected to play a crucial role in the transition to a production system more reliable electricity and low carbon emitter. Moreover, it does not seem obvious to those companies which put in place systems for capturing carbon gas plants is a sustainable competitive way of reducing emissions of greenhouse gas emissions in Britain.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">The United Kingdom plans to use a system of power generation in which fossil fuels retain an important place alongside renewables and nuclear power generating renewed. The use of carbon capture and storage of carbon for power plants operating from fossil fuels seems to register as a “miracle” solution relatively inexpensive, clean and reliably supplying UK consumers. The country also has significant advantages since the geological deposits of hydrocarbons in the North Sea, depleted, are privileged places for the storage of carbon dioxide from production of electricity. In these circumstances it seems logical that the country wants is already developing such devices for gas-fired plants to take advantage as soon as possible the potential for reducing emissions of greenhouse gases that leaves glimpse.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">–</p><p style="font-size: 11px; color: rgb(51, 51, 51); ">Carbon Capture and Storage</p><p style="font-size: 11px; color: rgb(51, 51, 51); ">1. Capture</p><p style="font-size: 11px; color: rgb(51, 51, 51); ">
Carbon dioxide is captured by different methods at the Central Electricity Generation<br>- Capture post-combustion carbon dioxide is taken from the flue gases from the combustion of hydrocarbons. This method is easily adaptable to existing plants.<br>
- Pre-combustion capture: the fossil fuel is processed upstream of the combustion in order to obtain carbon dioxide and hydrogen. The first is taken and only the second is burnt, producing water vapor.<br>- Capture by oxy-combustion air is treated upstream of the combustion so that it is done in the presence of pure oxygen. The fumes from the combustion are then of water vapor and carbon dioxide, easily separable by condensation to remove the second.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">2. Transportation</p><p style="font-size: 11px; color: rgb(51, 51, 51); ">Transport carbon dioxide captured prior to storage locations is done either by ship or by pipeline. The difficulties inherent in this step lies in the precise control of transport conditions, ie pressure and temperature.</p>
<p style="font-size: 11px; color: rgb(51, 51, 51); ">3. Storage</p><p style="font-size: 11px; color: rgb(51, 51, 51); ">The storage of carbon dioxide should be in sites where the gas is not captured previously in contact with the atmosphere for a very long time. There are three main options:<br>
- Deposits of oil or gas at the end of exploitation: these tanks which are well known geological features and favorable gas storage, in which the captured CO2 can occupy the volume left free by oil extracts.<br>- The non-mineable coal seams: the carbon dioxide can be stored in the pores of the carbon present in these veins.<br>
- Deep aquifers: the geological formations saturated with saline water exist in the world and have a storage potential of carbon dioxide high. However, the effect of CO2 storage in these formations is still the subject of research to be better understood.</p>
