Emissions & Generation Resource Integrated Database mix, and heat input. eGRID data also include plant identification, location, and structural information. The emissions information in eGRID include carbon dioxide (CO), nitrogen oxides (NO), sulfur dioxide (SO), methane (CH), nitrous oxide (NO),and carbon dioxide equivalent (COe). CO, CH, and NO are greenhouse gases (GHG) that contribute to global warming or climate change. NO and SO contribute to unhealthy air quality and acid rain in many parts of the country. eGRID's resource mix information includes the following fossil fuel resources: coal, oil, gas, other fossil; nuclear resources; and the following renewable resources: hydroelectric (water), biomass (including biogas, landfill gas
Carbon dioxide scrubber of carbon dioxide without expendable products. Regenerable systems allowed a shuttle mission a longer stay in space without having to replenish its sorbent canisters. Older lithium hydroxide (LiOH)-based systems, which are non-regenerable, were replaced by regenerable metal-oxide-based systems. A system based on metal oxide primarily consisted of a metal oxide sorbent canister and a regenerator assembly. It worked by removing carbon dioxide using a sorbent material and then regenerating the sorbent material. The metal-oxide sorbent canister was regenerated by pumping air at approximately through it at a standard flow rate of for 10 hours. Activated carbon can be used as
