Solar energy has a simple but annoying weakness. It disappears when the sun does. Even the most efficient systems struggle with this basic reality—no sunlight means no power. Scientists have long ...

Saudi researchers built an electricity-free cooler using salt and sun. See how NESCOD could revolutionize cooling in extreme ...

Scientists at U.C. Santa Barbara have developed a new kind of “liquid battery” that can capture sunlight and release it later as heat, a breakthrough researchers say could help solve one of renewable ...

The sun can provide limitless heat for buildings and industrial processes. But using that heat on demand means capturing and storing solar thermal energy for when the sun isn’t shining. Researchers ...

Curved molecules that absorb sunlight, store the energy, and re-release it as heat are pushing the boundaries in solar thermal storage technology. The anthracene systems, derived from a by-product of ...

(Nanowerk News) Hydrogen is widely regarded as one of the cleanest fuels for the future, producing only water when used. However, generating hydrogen efficiently and sustainably remains a major ...

A phase-change photothermal foam stores solar heat to sustain water evaporation after sunlight fades, producing fresh water from hypersaline brine at low cost. The phase-change photothermal foam ...
