With over 40,000 kilometers of long-distance transmission lines and more than 470,000 kilometers of distribution grid, Germany''s natural gas pipeline system is very well developed. Moreover, as a key transit country for gas supplies to its neighbors, it has the most expansive storage capacity of all EU members with a working gas volume of
Green hydrogen could contribute to climate change mitigation, but its greenhouse gas footprint varies with electricity source and allocation choices. Using life-cycle assessment we conclude that if electricity comes from
The figure below shows the forecast of the global range of levelized cost of hydrogen production for large projects through 2050. According to Bloomberg New Energy Finance, if these costs continue to fall, green hydrogen could be produced for $0.70 – $1.60 per kg in most parts of the world by 2050, a price competitive with natural gas.
