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

Green Car Congress

Traditionally, CO 2 is stripped from water-rich solvents and sent off site to be converted or stored underground. 2021), “Integrated Capture and Conversion of CO2 to Methane using a Water-lean, Post-Combustion CO2 Capture Solvent.” The new process gives off excess heat, too, providing steam for power generation.

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport. These could then be burned as needed. and Xiong, Y.

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

When powered by renewable solar or wind energy sources, the electrocatalytic CO 2 reduction reaction (CO 2 RR) is a promising approach to produce value-added chemicals/fuels and store renewable energy to achieve the goal of net-zero-emissions. C 2+ alcohols are desirable due to their high energy densities and large global market capacities.

In addition, storage of gaseous fuels and separation of by-products can be complicated—we want to get to the point where we can cleanly produce a liquid fuel that can also be easily stored and transported. —senior author Professor Erwin Reisner. The researchers are now working to further optimise the system and improve efficiency.

DOE’s Carbon Utilization and Storage Atlas estimates at least 2,400B metric tons of US CO2 storage resource

Green Car Congress

The United States has at least 2,400 billion metric tons of possible carbon dioxide storage resource in saline formations, oil and gas reservoirs, and unmineable coal seams, according to a new US Department of Energy (DOE) publication.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Over the long term, hydrogen-methane technology offers a further advantage: it allows surplus wind and solar power generated during peaks to be stored, and these surpluses will see a sharp increase as the share of this renewable energy grows. —Professor Buchal. —Prof.

Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Gasoline is liquid at room temperature and, therefore, much easier to handle than its gaseous short-chain siblings—methane, ethane and propane—which are difficult to store and prone to leaking back into the skies.
