Abengoa solar thermal energy storage systems having proved successful in the US, the company is now marketing standalone systems using molten salt, batteries and flywheels.

Abengoa: could molten salt do peaker job?

By Jason Deign Abengoa, perhaps best known for massive solar thermal plant such as Solana and Mojave, is pitching standalone molten salt storage systems and solar generation-connected thermal storage as a replacement for gas peakers. The multinational infrastructure…

Study points to PCM breakthrough

The case for using phase-change materials (PCMs) for thermal energy storage is being bolstered through research using a modelling technique out this year. The technique, developed by a team in Catalonia, Spain, has uncovered a PCM…

Solar thermal energy storage loses its way

Too much salt is not just bad for your health. It could also harm the likelihood of thermal energy storage (TES) cost reduction across the entire concentrated solar power (CSP) industry. Right now, molten salt TES is…

The tricky art of storing heat from the sun

A Chilean renewable energy tender that closed in October could be the first in the world where energy storage becomes the deciding factor for success. Great news for the industry? Perhaps. But actually it’s not…


China is to build a concentrated solar power (CSP) plant with a thermal energy storage system in Delingha, the province of Qinghai. Qinghai already contains more than 60% of the Chinese solar photovoltaic installed capacity. Photo credit: SSE
