Here is a rewritten version of the article in short, human-like sentences: **Electrolysis Efficiency Reaches New Heights** Scientists have set a new record for electrolysis. This process splits water into hydrogen and oxygen. The new method is much more efficient. It uses less energy to produce more hydrogen. This breakthrough could lower the cost of clean hydrogen. Hydrogen is a key fuel for a greener future. The technology is still in the lab. But it shows great promise for scaling up.
