Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. If implemented in the UK alone, the system could deliver cost savings of £1.28 billion in 5 years while reducing overall UK emissions by 2.9%.

Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials.

Study finds limiting warming to 2 °C would require at least a $200/t carbon tax globally

Green Car Congress

A study by University of Chicago economist Esteban Rossi-Hansberg, the Glen A. Lloyd Distinguished Service Professor in Economics, and José-Luis Cruz of Princeton University assesses the local social cost of carbon (LSCC) and how that cost aligns with the carbon reduction pledges countries made under the Paris Agreement.

CATL launches “condensed battery” with an energy density of up to 500 Wh/kg for aircraft; automotive version this year

Green Car Congress

At Auto Shanghai, Chinese battery giant CATL launched what it calls a “condensed battery”—a type of semi-solid state cell with an energy density of up to 500 Wh/kg. CATL says the cell can achieve high energy density and high level of safety at the same time, opening up a new electrification scenario for passenger aircraft.
