World Wildlife Fund supports plans to make CO2 capture and storage mandatory
Posted by gmarkets on 22 September, 2007
The WWF Climate Vision insisted that energy and climate policy deliver on climate, economic development and social progression objectives.
WWF’s climate vision emphasis: WWF Climate Solutions Vision (released 15 May 2007) outlines technological pathway based on:
· Decoupling energy services and primary energy production (energy efficiency & conservation);
· Accelerating low emission technologies (renewables & bio-energy);
· Displacing high carbon coal with low carbon gas; and
· Carbon capture and storage (makes biomass carbon negative).
Stop using fossil fuels:WWF is against the venting of CO2 from fossil fuel power generation! Coal, oil and gas are to remain significant features of current and future power generation. Action is needed urgently to review some technological solutions (CCS, natural gas, etc) as medium term bridging solutions to low carbon systems (renewables). The worst polluters need to close down their plant or make significant improvements.
Take out CO2 from atmosphere:WWF promotes action for carbon capture and carbon storage and accelerating plants which are more thermally efficient (making better use of waste heat from combustion). WWF noted that:
· Traditional power stations have typical thermal efficiency of around 30-38 per cent;
· IGCC has conversion efficiency factor of mid-40s but some plants offer up to 50 per cent;
· Supercritical have thermal efficiencies of 43-45 per cent; and
· Ultra-supercritical power plants can have 50 per cent efficiency.
Provide strong regulatory framework:WWF identified key components:
· Need to monitor carbon storage sites;
· Must monitor storage, quantify levels and declare any seepage;
· Operator to provide all available evidence indicating that they have a sound storage site;
· Critical information about dynamics of CO2 in underground storage sites; and
· Independent verification global standards.
Better economic integration: WWF highlighted the need to improve conversion efficiency with carbon capture and storage (CCS) as critical to engage effectively with emerging economies, including measures to:
· look into intellectual property rights or the development of CCS as a common good;
· require the storage operator to purchase permits in case of seepage as well as the cost of repair, clean up and other side environmental impacts; and
· ensure that the carbon price (in EU ETS) was sufficient to send appropriate market signals or to use another mechanism.
Future questions: WWF identified several areas which would require future investigation:
· What carbon price would be needed for the Clean Development Mechanism (CDM) to support upgrade and replacement power plant in emerging economies.
· Where are EUA permits raised?
· Capture, storage or both?
· Do oil companies sell space to power generators?
· What are the likely impacts on other sectors?
· Does CCS fit into carbon market timescale?
