Who would want Abengoa’s assets?

By Jason Deign Abengoa, the Spanish renewable infrastructure developer, is thought to be hunting buyers for assets, including a large amount of storage, as it faces bankruptcy. The company filed for preliminary creditor protection a fortnight…

The case for concrete energy storage

By Jason Deign The Norwegian firm EnergyNest is expected to announce the outcome of a pilot of its concrete-based thermal energy storage (TES) product soon, potentially within days. In September the company’s CEO, Christian Thiel, told…

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…

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…
