The transport sector accounts for about a quarter of total carbon dioxide emissions and is expected to be the highest source of greenhouse gases by 2035. Fortunately, using a new class of porous material, researchers designed an onboard compact system that captures 50% of CO2 emissions from long-haul semi-trucks—before it reaches the atmosphere. The system captures otherwise wasted exhaust heat using it to separate the CO2 and regenerate the MOF (porous materials called metal-organic frameworks) materials. They’re promising for carbon dioxide capture because they don’t react chemically with the gas, storing it in their cage-like structure, making it easy to separate the gas using little energy. The system designed captures half of the otherwise emitted CO2 at 96% purity, while needing only 7.6 percent extra engine power to operate and with a volume less than 1.5 cubic meter.
