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. Though it is a greenhouse gas and requires careful supply chain management, methane has many applications, ranging from household use to industrial processes, said co-author and PNNL chemist Jotheeswari Kothandaraman.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

Audi’s e-gas plant. Audi has opened its e-gas plant in Werlte, making it the first automobile manufacturer to develop a chain of sustainable energy carriers. The Audi e-gas plant, which can convert 6MW of input power, utilizes renewable electricity for electrolysis to produce oxygen and hydrogen. Because there is not yet a widespread hydrogen infrastructure, the hydrogen is reacted with CO 2 in a methanation unit to generate renewable synthetic methane, or Audi e-gas.
