New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The solar-powered catalyst is made from abundant materials and works in a configuration that could be mass-produced. 1 under air mass 1.5 —Zhou et al.

Prometheus CEO outlines tech advances that could make CO2-to-fuels renewable gasoline and jet price-competitive with fossil fuels

Green Car Congress

Recent breakthroughs in separations and catalysis, along with long-trend reductions in solar and wind electricity costs, have significantly increased the potential for cost-competitive renewable fuels from direct air capture (DAC) of CO 2. The separation of ethanol and other fuel products from water. —Rob McGinnis.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

. … Initial scaling is efficiently applied to available concentrated, hot sources of CO 2 , such as eliminating the CO 2 emission from industrial smoke stacks and simultaneously forming valuable CNT wool. Larger scale C2CNT can be achieved through direct elimination of atmospheric CO 2 using solar heat and solar to electric PVs.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. SRI’s approach makes it economical to use carbon-neutral electricity, such as nuclear, hydro, or solar as a source of additional energy. Bottom: SRI process.

New black silicon-supported catalyst for photoreduction of CO2 to methane

Green Car Congress

Researchers at the University of Toronto have developed a catalyst comprising of black silicon nanowire supported ruthenium ( Ru/SiNW) for the photochemical and thermochemical reduction of gaseous CO 2 to methane (methanation) in the presence of hydrogen under solar-simulated light. 1 under 14.5 reduction of gaseous CO 2 by H 2.

Empa researchers investigating new process for production of synthetic methane

Green Car Congress

Such fuels, produced synthetically with renewable energy, can be transported via conventional routes and made available through the existing infrastructure. Methanization works by producing methane (CH 4 ) and water (H 2 O) by catalytic conversion from carbon dioxide (CO 2 ) and hydrogen (H 2 ). Schröter K., Dimopoulos Eggenschwiler P.,
