Academics examine hydrogen as commercially viable storage

Using excess wind and solar to produce hydrogen, before storing it for later use, could keep costs down and stabilise the grid, according to new academic research.

Stefan Reichelstein, of Stanford University, and Gunther Glenk, of the Technical University of Munich, sought to uncover whether the sharp fall in renewable energy costs meant the production of hydrogen from renewable power through a power-to-gas process could become more economical.

The research, using data from the US and Germany, found that while renewable hydrogen is cost competitive in niche applications, the same can not be said for an industrial-scale supply. However, with recent market trends suggesting that this will change within a decade, Reichelstein said: “hybrid energy systems will significant advance the business case for both renewable power and carbon-free hydrogen.”
