ARS Technica (Oct 04, 2018): Company that sucks CO2 from air announces a new methane-producing plant

• "The plant consists of three air collectors that are more energy-efficient than Climeworks' first ambient air collector. "The plant will filter up to 150 tons of CO2 from ambient air per year," Climeworks said in a press statement. "Simultaneously, an alkaline electrolyser (1.2 MW) locally generates 240 cubic meters of renewable hydrogen per hour by making use of excess on-site photovoltaic energy." A catalyst then combines the CO2 and the hydrogen into methane gas in a reactor built by a French company called Atmostat. The methane "is then liquified and used to fuel natural gas lorries," Climeworks says."
