Scientists just found a new way to split water into hydrogen and oxygen that’s cheap and effective – and it could mean we’re able to produce an abundance of clean hydrogen fuel in the future.
Hydrogen is a fantastic source for clean energy, but the challenge is making enough of it to be efficient and practical price. A newly developed catalyst now reportedly addresses both issues, boasting more efficiency for a lower cost than existing solutions – and it can run for 20 hours straight.
