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

Green Car Congress

The process is constrained by the (low) cost of electricity. Initial scaling is efficiently applied to available concentrated, hot sources of CO 2 , such as eliminating the CO 2 emission from industrial smoke stacks and simultaneously forming valuable CNT wool. —Johnson et al.

Porsche, Siemens Energy and partners advance climate-neutral eFuels development; Haru Oni pilot in Chile

Green Car Congress

Electrolyzers will use wind power to produce green hydrogen. The Haru Oni pilot project in Magallanes Province takes advantage of the excellent wind conditions in southern Chile to produce climate-neutral fuel with the aid of green wind power. Enel is a co-funder of the plant, with a focus on wind power and electrolysis.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

In both electric- and hydrogen-favoring cases, availability of low-carbon electricity and hydrogen prolonged the use of petroleum-fueled ICE vehicles. For example, the study found that the availability of carbon capture and storage (CCS) technology has a major impact on the lowest cost passenger vehicle fuel and technology choice.

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

Green Car Congress

The novel SMART-DAC technology is a natural wind driven process that captures CO 2 directly from air using membrane gas absorption with a liquid absorbent and regeneration of the absorbent by electrodialysis. Biochar can potentially make a major contribution to the UK target for Greenhouse Gas Removal (GGR) of 35M tonnes of carbon (MtC) p.a.
