PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known. Using EEMPA instead reduces the energy needed to fuel such a reaction.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. The research was published in the ACS journal Industrial Engineering and Chemical Research. Skimmers don’t work in rough waters or with thin layers of oil. —Vinayak Dravid, who led the research.

million) STORE&GO research project. In this second stage, hydrogen from regenerative energy sources is converted into methane (CH 4 ), i.e. synthetic natural gas, using CO 2 from a bio-ethanol plant. This stored energy is then available as backup whenever there is an insufficient supply of solar and wind power.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The Swiss company Climeworks is building the world’s largest direct air capture (DAC) and storage facility for converting atmospheric CO 2 to rock in Iceland. Water from the Hellisheiði power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth.

Australian researchers develop new hybrid plasma electrocatalytic process to produce green ammonia

Green Car Congress

The method makes green ammonia from air, water and renewable electricity and does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound. And we saw tragically in Beirut recently how potentially dangerous storing ammonium nitrate can be. —Dr Lovell.
