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

Green Car Congress

Researchers from Huazhong University of Science and Technology in China and George Washington University in the US report in a new paper in the ACS journal Accounts of Chemical Research that a range of important carbon nanomaterials can be produced at high yield by molten carbonate electrolysis.

Estonian startup UP Catalyst secures €2.09M; sustainable carbon nanomaterials and graphite from CO2

Green Car Congress

Estonian startup UP Catalyst, a company developing a method to produce sustainable carbon nanomaterials and graphite from CO 2 , has closed a successful pre-seed round of €500,000, in addition to €1.59 Most of the carbon materials on the market are produced by employing expensive and environmentally harmful methods.

Study: Fossil fuel CO2 emissions reached max daily decline of 17% in April

Green Car Congress

A preliminary analysis of global data has found that carbon dioxide emissions from fossil fuel sources reached a maximum daily decline of 17% in April as a result of drastic decline in energy demand that have occurred during the COVID-19 pandemic. Estimates were then compared against daily emissions data from the same period in 2019.

T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

T&E has commissioned Emissions Analytics to test three of the most popular PHEVs sold in 2019: a BMW X5 (longest EV range PHEV available), a Volvo XC60 and the Mitsubishi Outlander. Unless you drive them softly, carbon emissions can go off the charts. Governments should stop subsidising these cars with billions in taxpayers’ money.

Licht Group reports high-yield, low-energy synthesis of carbon nano-onions from CO2

Green Car Congress

Stuart Licht ( earlier post ) report a process for the high-yield, low-energy synthesis of carbon nano-onions (CNOs) by electrolysis of CO 2 in molten carbonate. High yield electrolytic synthesis of carbon nano-onions from CO 2 , either directly from the air or from smoke stack CO 2 , in molten carbonate. —Prof.

Researchers develop wave-energy-driven CO2 reduction system for production of carbon-based liquid fuels

Green Car Congress

Despite extensive research on improving the charging efficiency of the capacitor by the TENGs, further studies are still needed since the load capacitance of the capacitor and inherent capacitance of the TENG will depend on the targeted energy production and TENG design. In addition, Zi et al. —Leung et al.

Study finds that steel slag heaps could absorb significant amounts of CO2

Green Car Congress

Slag is rich in calcium silicates that dissolve in water; when atmospheric CO 2 dissolves in water to form carbonic acid, it reacts with the dissolved silicates to form stable carbonate minerals such as calcite, which nearly permanently sequesters the carbon. are reported. while average calcium (Ca) levels exceeded 30%.
