Power Plant CCS - Site and Blog for CO2 Capture and Sequestration
Here's an interesting site (and blog) dedicated to CO2 sequestration at power plants. Aptly called Power Plant CCS, it provides the latest updates on CCS at power plants worldwide. More interestingly, it has a special emphasis on researching the newest and novel methods for CCS at these plants.For instance, there are three novel approaches about which detailed inputs are provided: CO2 sequestration using mineral carbonation, algae-based CO2 capture,
Carbon Mitigation through use of Biomass instead of Coal .
Given that carbon capture and storage is likely to be one of the most important concepts that the world will be keen on researching, and also given that power plants have an urgent need to become less CO2 polluting, this is indeed an important site.
Good stuff.
