SolarReserve chases even hotter molten salt

By Jason Deign SolarReserve, the solar thermal plant developer, is going after molten salt storage systems of more than 700ºC with a USD$2.4m award from the US government. The award, announced last Wednesday, comes from the US…


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…

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…

CSP benefits from energy storage

Concentrated solar power (CSP) has one key advantage over the ever-cheapening photovoltaic (PV) competition: the ability to directly integrate thermal energy storage (TES) and thus provide dispatchable energy. It’s perhaps with this in mind that…


SEGS I and II plants will include energy storage as part of a major overhaul.

30-year CSP plants to add storage

Concentrated solar power (CSP) has been in the United States for the best part of three decades. And it looks like two of the great pioneers of this expanding industry have plenty of life in…
