From the website of Germany’s global industrial giant Siemens, comes a very clear explanation of the role that electrolyzing hydrogen is already playing in making sure clean renewable energy actually gets used instead of wasted or curtailed.  Below are some key excerpts:

“When it comes to power generation and distribution, hydrogen is set to become increasingly important. It will not only store the power from excess electricity generated by wind and solar plants but will also serve as a fuel for cars. What’s more, it can be combined with renewably-produced carbon dioxide to produce a feedstock for plastics production.

And when it comes to storing the power produced by excess electricity, electrolysis is set to play a key role. Here, water is decomposed into oxygen and hydrogen gas by means of an electrical current.”
