Carbon capture and storage gets a bad rap from its associations with ‘clean coal’. But the technology could prove vital in cutting emissions from other industries like steel, cement and chemicals.
Storing waste CO2 in rock? Results from a test site at a geothermal plant in Iceland show that CO2 mixed with water can be turned into minerals in locations with basalt volcanic rock.
New analysis reveals carbon capture at coal power plants is significantly more expensive than thought, making renewables and natural gas power generation more attractive.
For more than a decade the coal industry’s favoured response to climate change was carbon capture and storage, or CCS. CCS is still the main defence, but the absence of functioning projects is making it ever more threadbare.
Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
Divestment campaigns aim to halt the use of fossil fuels, but the climate can be also stabilized through ‘recarbonization’ techniques, such as reforestation and changing agricultural practices.
