DOE launches Clean Fuels & Products Shot

Green Car Congress

The US Department of Energy (DOE) launched the Clean Fuels & Products Shot , a new initiative that aims to reduce greenhouse gas emissions (GHGs) from carbon-based fuels and products significantly. Biomass and waste conversion technologies designed to use green electricity and hydrogen to maximize carbon retention in products.

GTI quantifies opportunity to produce low-carbon renewable natural gas (RNG) from wood wastes

Green Car Congress

GTI has released a site-specific engineering design titled “ Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes ”. According to the analysis, California has the potential to produce tens of billions of cubic feet of RNG per year from the wastes that are now being used for biomass-based electricity. Source: GTI.

EPA finalizes greenhouse gas standards for LDVs MY 2023-2026

Green Car Congress

The Environmental Protection Agency (EPA) is finalizing the federal greenhouse gas (GHG) emissions standards for passenger cars and light trucks for Model Years (MY) 2023 through 2026. EPA is planning to initiate a separate rulemaking to establish multi-pollutant emission standards under the Clean Air Act for MY 2027 and later.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The novel use of carbon dioxide (CO 2 ) electroreduction to generate carbon-based products which do not contribute to the greenhouse effect has promoted the vision of carbon dioxide as a renewable feedstock for future clean fuel production. We conclude that CO 2 depletion causes a strong decay in the electrochemical reaction efficiency.

Supreme Court curbs EPA authority to regulate CO2 from power plants

Green Car Congress

The opinion holds that Congress did not grant EPA in Section 111(d) of the Clean Air Act the authority to devise emissions caps based on generation shifting—i.e., forcing a shift from higher-emitting to lower-emitting producers. Under our precedents, this is a major questions case. . … For the reasons given, the answer is no.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The researchers think that it could be recycling smokestack carbon dioxide into clean-burning fuel within 5-10 years. Thirty percent of the energy in the US comes from natural gas. The chief advance is that the team has harnessed relatively large electrical currents with a device that should be possible to mass produce.
