GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). The majority (about 60%) of those CO 2 emissions result from the production of lime. The majority of CO 2 emissions occurs during the decarbonation of limestone (CaCO 3 ) to lime (CaO).and

Testing solar radiation management as a geoengineering technique

Green Car Congress

Solar radiation management (SRM) is one of the geoengineering techniques proposed as a potential means of offsetting some of the anthropogenic radiative forcing of climate as a means to reduce climate change. To take geoengineering methods like solar radiation management seriously, we need to build realistic models. Earlier post.)
