XPrize in Carbon Removal Goes to Enhanced Rock Weathering

Cars That Think

The XPrize Foundation today announced the winners of its four-year, US $100 million XPrize competition in carbon removal. Contestants in the carbon removal XPrize had to demonstrate ways to pull carbon dioxide from the atmosphere or oceans and sequester it sustainably. How Does Enhanced Rock Weathering Remove CO2?

First Supercritical CO2 Circuit Breaker Debuts

Cars That Think

Researchers this month will begin testing a high-voltage circuit breaker that can quench an arc and clear a fault with supercritical carbon dioxide fluid. The greenhouse warming potential of SF 6 is nearly 25,000 times as high as that of carbon dioxide, he notes. In Georgia Techs design, supercritical carbon dioxide quenches the arc.

How Significant Will The European Emissions Rollback Actually Be?

The Truth About Cars

Europe is relaxing CO2 emission targets after receiving feedback from automakers. European Commission President Ursula von der Leyen issued an announcement earlier this month that manufacturers would receive a two-year extension for meeting the planned tighter CO2 emissions rules for 2025. Everything else will remain the same.

Government to offer £3,750 to EV buyers

EV Info

The spokesperson said bands (which could expand beyond two) are determined by how much CO2 is emitted in an EV’s production, assessing the energy used in vehicle assembly as well as battery manufacturing. Scores are relative to an index based on the carbon intensity of different [power] grids.” And no Chinese made EVs.

“A Bundle Of Cash!” Australia’s new CO2 reduction scheme can be lucrative for EV brands, predicts local XPeng importer

EV Central

While legacy auto makers ponder the financial impact of Australia’s new CO2 reduction scheme, the local importer of Chinese XPeng electric vehicles says there is the potential for EV-only brands to make a bundle of cash. Exceeding the CO2 emissions target will cost brands up to $100 per gram of CO2 per vehicle imported.

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

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The most compact form of captured carbon is through its transformation to solid carbon.

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

Electrochemical reduction of carbon dioxide (CO 2 ) is a promising approach to solve both renewable energy storage and carbon-neutral energy cycle. In order to improve the economic feasibility in applications, electrocatalytic CO 2 reduction with high activity, selectivity, and stability toward multi-carbon products should be realized.
