PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

EPFL scientists have developed an Earth-abundant and low-cost catalytic system for splitting CO 2 into CO and oxygen—an important step towards achieving the conversion of renewable energy into hydrocarbon fuels. Using only Earth-abundant materials to catalyze both reactions, this design keeps the cost of the system low.

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

The only by-products are liquid water and a stream of high-purity, pipeline-ready CO 2. 8RH2-produced ammonia will provide a transportable low-carbon source of hydrogen, a low-cost and scalable solution to accelerate the global transition to net-zero.

Thai researchers find waste chicken fat a good low-cost feedstock for renewable diesel

Green Car Congress

In a study investigating the effect of the water and free fatty acid (FFA) content in waste chicken fat from poultry processing plants on the production of renewable diesel (not biodiesel), researchers in Thailand have found that both higher FFA and water content improved the biohydrogenated diesel (BHD) yield. 1, a water content 0?4

Biofeedstock company Proterro hits milestones with bioreactor for sucrose produced via cyanobacteria; commissioning pilot plant

Green Car Congress

Using CO~2, sunlight and water, Proterro lowers the cost of sugar production to around $0.05/lb This process yields a fermentation-ready sucrose stream, rather than a mixture of sugars, allowing simple, low-cost downstream processing. —Kef Kasdin.

GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

Furthermore, the removed CO 2 is permanently stored, unlike, other methods like the production of fuels or seltzer water that re-release CO2 when the product is used. Approximately 4 tonnes of CO 2 is absorbed in this process for every tonne of carbon nanotubes produced.
