Nominee for EBA Conference Poster Award 2016 Power-to-Gas by Biomethanation- From Laboratory to Megawatt Scale

摘要

The share of renewable energy on total energy production has been rising. Wind and solar produce electricity intermittently and generally independent of demand. Bulk energy storage by an integrated Power-to-Gas system is the most promising solution toaddress the need for such challenge. In the Power-to-Gas process, low-cost and stranded electricity from wind and solar is utilized to convert carbon dioxide into methane, the principal component of natural gas (Sterner 2009, Gotz 2015).This renewable gas can then be injected into existing natural gas pipeline infrastructure and stored for days, weeks and even months without losses. It can also be used in the transportation sector or in industrial processes.
