Technology has matured enough to produce effective wind turbines. The next technological challenge is how to store intermittent electricity generated by these wind turbines. The most promising technology is power-to-gas: use electricity from wind to split water in H2 and O2 molecules and burn (reunited) them at a later point in time.
This project produces 163 bar hydrogen, without the need of an external compressor. The resulting hydrogen can be directly fed into the existing natural gas network.
