Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water

Green Car Congress

The results, reported in the journal Nature Energy , represent a new method for the conversion of carbon dioxide into clean fuels. The wireless device could be scaled up and used on energy farms similar to solar farms, producing clean fuel using sunlight and water. —senior author Professor Erwin Reisner. Qian Wang et al.

Evonik and Siemens Energy commission pilot plant for conversion of CO2 to chemicals

Green Car Congress

Just as plants use solar energy to produce sugar, for example, from carbon dioxide (CO 2 ) and water in several steps, artificial photosynthesis uses renewable energies to produce valuable chemicals from CO 2 and water through electrolysis with the help of bacteria.

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

In a paper published in the journal Joule , they suggest that the results show great potential for the electrocatalytic conversion of CO 2 into value-added chemicals. Electrochemical reduction of carbon dioxide (CO 2 ) is a promising approach to solve both renewable energy storage and carbon-neutral energy cycle. (C

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

In the Solar Thermal Electrochemical Process (STEP), developed by Professor Stuart Licht and his group at GWU, solar UV–visible energy is focused on a photovoltaic device that generates the electricity to drive the electrolysis, while concurrently the solar thermal energy is focused on a second system to generate heat for the electrolysis cell.

CEMEX, Sasol and ENERTRAG partner to turn CO2 from cement plant into Sustainable Aviation Fuel

Green Car Congress

The consortium will source green hydrogen generated exclusively from wind and solar energy from ENERTRAG. To reach carbon neutrality, these emissions must be captured, stored, or repurposed in some way. Sixty percent of the carbon emissions in the cement production process come from the chemical reaction that occurs in cement kilns.

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

Green Car Congress

Partially because of this heat, the Brayton cycle has the potential to be much more efficient at turning heat from power plants—nuclear, natural gas or even concentrated solar—into energy than the traditional steam-based Rankine cycle. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

PSI team demonstrates direct hydrocarbon fuel production from water and CO2 by solar-driven thermochemical cycles

Green Car Congress

Solar-driven thermochemical cycles offer a direct means of storing solar energy in the chemical bonds of energy-rich molecules. This new concept, if high selectivity for hydrocarbons is achieved, inherently bypasses a second stage conversion, such as methanation or Fischer-Tropsch processes. doi: 10.1039/C6EE00862C.
