The Fraunhofer Institute for Solar Energy Systems has achieved a new milestone in green hydrogen production. Its experimental photoelectrolysis installation converts nearly a third of sunlight directly into clean fuel. This breakthrough brings the technical feasibility of this emission-free technology closer.
Direct photoelectrolysis: panels that produce hydrogen 🔬
The system combines high-efficiency solar panels with an integrated electrolyzer, avoiding losses from intermediate conversion. By splitting water into oxygen and hydrogen without additional steps, it achieves that 31.3% efficiency. This is a world record for this type of configuration, surpassing previous marks by several points.
Hydrogen: that fuel that always arrives in 5 years ⏳
Every so often, a laboratory announces a record promising cheap and abundant hydrogen. Meanwhile, in the real world, we keep filling tanks with gasoline and debating whether the electric car is expensive. But no worries: in five years we will have hydrogen at the pumps, or perhaps nuclear fusion. Hope springs eternal.
