(Bloomberg) --Three million miles of natural gas pipelines criss-cross the U.S., and the fight against climate change could render them all obsolete.
The last two weeks alone illustrate the stakes. President Joe Biden canceled the permit for the $9 billion Keystone XL oil pipeline on his first day in office, a clear signal any new fossil fuel pipeline project in the U.S. will face long odds.So pipeline owners are eyeing another, possibly future-proof fuel: hydrogen.
Unlike natural gas, hydrogen can be burned without pumping carbon dioxide into the air. Run it through a fuel cell to generate electricity and the only waste is water; produce hydrogen using electrolyzers powered by solar plants or wind farms and it becomes a way to store massive amounts of renewable energy—far more than any of today’s batteries can hold. And the best part for pipeline companies: getting it where it needs to be, in bulk, could require the same basic infrastructure that now carries natural gas - Link
