One of the key challenges the world will need to face during the 21st century is global warming and the consequent climate change. Its presence is indisputable, and decarbonizing the gird emerges as one of the required pathways to achieve global sustainable objectives. Solar energy power plants have the potential to revert this situation and …
A guest post by Alina Gilmanova, who provides a unique perspective from her work inside China Recently some media, such as Energyskeptic, falsely accused CSP technology of being unreliable, full of glitches and having a low energy return. Their opinion refers to certain early development faults of the technology, mainly based on the US experience, …

Keeping storage tank corrosion rates to a minimum is considered vital for use of molten salts in storage devices for electricity. Stephen Mraz The next-generation of concentrated solar power plants will require high-temperature fluids, such as molten salts in the range of 550 to 750°C, to store heat and generate electricity. At those temperatures, however, …

The Cerro Dominador project has successfully carried out the molten salt pumping tests towards the receiver, being one of the latest milestones of this project that prepares its interconnection to the National Electric System, since it is the prelude to the synchronization of the plant, where the molten salt storage system makes it possible for …
Gonzalo Martín, General Secretary of Protermosolar, will analyze what the role of concentrated solar power plants will be in energy storage within a decade at the I Energy Storage Congress (ALEN’20). Currently, thermal storage in molten salts in solar thermal power plants reaches 7 GWhe in Spain. This type of storage can perform two main …
Clean solar energy with storage can help Europe reduce emissions and deliver a secure and cost-effective electricity supply. EU-funded research suggests that fluidised crystal particles trump molten salts as the heat transfer and storage medium. © Gilles Flamant Current state of the art concentrated solar power (CSP) plants use central receivers with several options for …
One conundrum for the two main Concentrated Solar Power (CSP) technologies is how to be both bankable and efficient. Parabolic trough CSP is often considered more bankable, while central tower plants are more efficient. Trough technology is about a decade older than tower and has built up experienced supply chains, making it more bankable, which …

As reported by the company developing the project, «the salts produced by the SQM mining company have the capacity to conserve the energy captured during the day by the plant and maintain it in a tank storage system.» The development of the Cerro Dominador thermosolar project met a new milestone: to finish smelting 46,000 tons …
