‘Radical’ solar technology breakthrough allows energy to be stored for up to 18 years

Solar energy that lasts 18 years in a bottle? Researchers at Sweden’s Chalmers University have built a molecule that absorbs sunlight, holds it as a liquid, and releases it as electricity only when a catalyst says go. To prove it works, they charged the liquid with Swedish sun, shipped it to a partner lab in China, and three months later powered a tiny chip — just 800 nanometers thin — that turned the stored sunlight into electricity. Output is still small, but the concept is validated. If it scales, it points toward a future where clean energy isn’t tethered to grids or mining-heavy batteries, but travels quietly in a jar to wherever people need it.
