Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.

UK to award £54M to 15 projects developing innovative carbon removal technology

Green Car Congress

The UK government is awarding £54 million to 15 projects to develop technologies that remove carbon emissions from the atmosphere. The carbon dioxide can then be permanently stored or used in various products or applications. The biochar is rich in carbon and can be used as a fertilizer. Cambridge Carbon Capture Ltd.,

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

The WTG CO 2 emissions vary from 180% (nearly twice) to a reduction of 75% compared to that of the business as usual scenario without carbon sequestration. With the cost of carbon emissions being appropriately included, this electricity to synthetic fuel pathway will be even more economically competitive. Stubbins, and Paul J.
