A Spanish scientist has developed a system that reportedly produces hydrogen on-site without expensive electrolysis. The prototype utilises a water tank that is initially filled with water, ferrosilicon, and sodium hydroxide.

Spanish energy and construction giant Acciona plans to massively expand its investment in Australian renewable projects over the next five years, following the new federal government’s pledge to upgrade national electricity transmission networks.

Developed by researchers in Spain, the battery uses renewable electricity to melt low-cost metals such as silicon or ferrosilicon alloys to produce and store latent heat, which is in turn used by a thermophovoltaic generator to produce power. According to its creators, the device may store electricity at a cost of €10 per kilowatt-hour (AU$14.6/kWh) for a 10MWh system.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh (AU$0.18/KWh)

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.

A consortium led by Australian financial group Macquarie Asset Management will acquire French solar developer Reden Solar. The $3.7 billion (€2.5 billion) transaction is expected to be finalised in the third quarter of this year.

Spanish renewables group Gransolar says backing from international financier will “supercharge” its growth plans in Australia.

Spanish renewable energy company Acciona is using a robot dog, instead of drones, to monitor a solar park in northern Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the different PV plant components, as it walks between the panel rows following a programmed route.

Gelion’s zinc-bromide Endure batteries will undergo commercial tests at the 1.2 MW Montes del Cierzo testing field Spanish renewable energy company Acciona Energía operates in Navarra, in the north of Spain.
