CCS sidelined by tenuous financingJuly 7, 2013 5:51 pm Leave your thoughts
Carbon, capture and storage (CCS) has still not proven to be anything else than an inordinately expensive technology on an experimental level. Nevertheless the European Commission continues to embrace it.
New coal powered plants are still constructed in the EU and could still be operating in 2050, even though it would be totally inconsistent with the 80 percent CO2 reduction target for that time. Rather than phasing out fossil fuels, however, the European Commission is resolved to “decarbonise” power stations and heavy industry using carbon capture and storage (CCS).
This technology is regarded essential e.g. by the EU Commission for limiting global warming to 2°C if coal dependency is not abandoned. Yet the decarbonisation objective must be implemented worldwide, since
Estimates of the International Energy Agency (IEA) indicate that equipping 3,400 power plants and industrial facilities with CCS could provide 19 per cent of the total CO2 avoidance required by 2050. However action will be needed before 2030, since the maximum two-degree 1,000 billion tonne CO2 budget calculated by the ZÃ¼rich Technical Institute (ETH) for 2000 – 2050 would be exceeded by that time based on the current emissions trajectory. The necessary pace of implementation translates to a new CCS power plant or factory built every two days over the next 18 years. Adequate geological and logistical prerequisites for CO2 storage remain highly questionable at the scale required.
This perspective also neglects over 1,100 coal power plants counted by the World Resources Institute that are currently being designed or built without CO2 capture. Three quarters of the projects are located in
In a report presented in April 2013 to the “Clean Energy Ministerial” (governments representing 80 per cent of global CO2 emissions), the IEA has conceded that there are now only 13 large-scale CCS demonstration projects worldwide, and not one commercial plant with carbon dioxide separation.
The prospects for CCS are impeded in
The Swedish state power corporation Vattenfall forecast in 2001 that an “avoidance cost for a whole system” of “about 30 €/ton of CO2” could ultimately be achieved. CCS investments were to be offset by the EU Emissions Trading Scheme (ETS), affirmed by Directive 2009/29/EC to be “a predictable path” for controlling emissions. However, the IEA has since estimated CCS costs of US $50-65/ton of CO2 by 2030 for coal combustion and up to US $90 for gas-fired power plants. By contrast, ETS prices are languishing below €5/ton of CO2. The European Commission concluded on 27 March 2013, that at “current ETS prices well below €40/ton of CO2, and without any other legal constraint or incentive, there is no rationale for economic operators to invest in CCS”.
The Earth’s atmosphere will thus remain a no-charge CO2 repository unless alternative decarbonisation strategies can be implemented. Yet carbon taxes imposed for this purpose would restrict the development of EU energy-intensive industries, many of which are proving more cost-effective in
On 10 October 2012, the Commission responded to this challenge by announcing “a number of priority actions to stimulate investments in new technologies” for bringing industry back to
