Researchers assessed properties of coal-bioenergy gasification systems combined with carbon capture and storage (CBECCS) in China that use crop residues as biomass inputs and found that a crop residue ratio greater than 35% could allow for generation of electricity with net-zero life-cycle emissions of greenhouse gases at a cost of approximately 9.2 US cents/kWh at a carbon price of $52 per ton; the findings suggest that CBECCS systems offer a carbon-negative alternative for electricity generation while also helping to reducing air pollution.
