New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

The researchers combined a copper electrocatalyst with an ionomer [polymers that conduct ions and water] assembly that intersperses sulfonate-lined paths for the H 2 O with fluorocarbon channels for the CO 2. Here, we present a catalyst:ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron transport.

Yamaha and Sumitomo demo on-board thermoelectric generator for CO2 reduction

Green Car Congress

a Sumitomo Corporation Group company, jointly demonstrated a new waste heat recovery system based on a thermoelectric generator (TEG), which generates electrical power via exhaust gas heat. The existing water pump on the vehicle was used to supply coolant to TEG unit. An additional test achieved the target gas temperature.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

Audi’s e-gas plant. Audi has opened its e-gas plant in Werlte, making it the first automobile manufacturer to develop a chain of sustainable energy carriers. The Audi e-gas plant, which can convert 6MW of input power, utilizes renewable electricity for electrolysis to produce oxygen and hydrogen. Click to enlarge.

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.

H2 Green Steel and BMW Group sign final agreement on delivery of CO2-reduced steel

Green Car Congress

In a pioneering move, both companies have therefore agreed to have 40% of the pre-consumer steel scrap of the volumes returned to H2 Green Steel's electric arc furnaces for re-cycling. The direct reduction reactors have been up and running for more than 50 years in places where natural gas can be procured cheaply.

Audi in new e-fuels project: synthetic diesel from water, air-captured CO2 and green electricity; “Blue Crude”

Green Car Congress

Audi’s latest e-fuels project is participation in a a pilot plant project in Dresden that produces diesel fuel from water, CO 2 and green electricity. The sunfire plant, which operates according to the “power-to-liquid” (PtL) principle, requires carbon dioxide, water and electricity as raw materials. The Audi e?gas

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

Thirty percent of the energy in the US comes from natural gas. —Zetian Mi, U-M professor of electrical engineering and computer science, who co-led the work with Jun Song, professor of materials engineering at McGill University. It can use the sun’s energy or an electrical current to break down the carbon dioxide and water.
