    The breakthrough comes from giving electricity a shorter trip. Instead of sending solar power through conversion electronics before it reaches an electrolyzer, the design connects advanced solar cells directly to the water-splitting equipment. Fewer steps. Less energy lost along the way. Cost, durability, and scale, however, remain open questions.
