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

Researchers produce green syngas using CO2, water and sunlight

Green Car Congress

Researchers from the University of Michigan and McGill University in Canada report photochemical syngas synthesis using a core/shell Au@Cr 2 O 3 dual cocatalyst in coordination with multistacked InGaN/GaN nanowires (NWs) with the sole inputs of CO 2 , water, and solar light. This will significantly reduce overall CO 2 emissions.
