UK to award £54M to 15 projects developing innovative carbon removal technology

Green Car Congress

The money will help projects further develop their greenhouse gas removal technologies, which include a machine that can pull carbon dioxide out of the air, a plant to convert household waste into hydrogen for use in the transport industry, and a system to remove carbon dioxide from seawater. Biohydrogen Greenhouse Gas Removal Demonstration”.

ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources. Earlier post.).

Construction starts on “Flybus” demonstrator; low-cost flywheel energy storage hybrid projects 20% savings in fuel consumption

Green Car Congress

Central to the project is the use of a compact high-speed flywheel as an energy store, recycling the kinetic energy that would otherwise be wasted whenever the vehicle brakes. Flywheel hybrids, just like electrical hybrids, recycle the kinetic energy that would otherwise be wasted when the vehicle brakes.

Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. However, it is currently limited by high cost. Repurposing tropical forest would harm biodiversity.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). are expected to be widely available only as supercritical CO 2 in pipelines destined for geologic storage.
