Spain’s grid operator Red Eléctrica and regulator CNMC have launched real-time voltage control services, allowing renewable energy installations to provide dynamic grid support under a new regulatory framework.

Researchers at Ulm University and Friedrich-Schiller-Universität Jena have built a molecular system that captures solar energy in a water-soluble redox copolymer, stores it at more than 80% charging efficiency for several days, and releases it as hydrogen with 72% conversion efficiency whenever required.

Spain’s Fundación Ciudad de la Energía (Ciuden), a government energy research foundation, has completed operational testing of a 1 MW/8 MWh vanadium redox flow battery (VRFB) system at its Cubillos del Sil technology center, which it says is the largest vanadium flow battery in Europe dedicated to applied research.

The European Network of Transmission System Operators for Electricity (Entso-E) has published its final root cause report on the April 28, 2025, blackout in Spain and Portugal, finding failures across grid operations, generation, and regulations, and issuing 22 recommendations to strengthen European grid resilience.

The Silicon and New Concepts for Solar Cells (SyNC) research group at the Institute of Solar Energy (IES) of the Polytechnic University of Madrid (UPM) has produced high-efficiency two-dimensional solar cell prototypes using the “hot-pick-up” technique, with simulations suggesting the cells could meet up to 30% of a building’s energy needs when applied to facades.

The system enables measurements under controlled irradiance, spectrum, and temperature conditions. It can combine 0.4% spatial irradiance uniformity, 500 ms illumination pulses, and dynamic I-V acquisition to accurately test high-capacitance photovoltaic modules in a single pulse, according to Ciemat.

Atome says it has secured a $420 million debt package for a $650 million low-carbon fertilizer project in Paraguay producing 260,000 metric tons (MT) per year, while Asahi Kasei says it has begun installing a 1 MW-class electrolyzer at Finland’s first commercial hydrogen refueling station.

GlobalData says global renewable capacity will more than double to 8.4 TW by 2031, with PV reaching nearly 6 TW, a 13% compound annual growth rate from 2025 levels of 4.1 TW.

An Algerian research team has developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimizing water use in desert conditions. The system raised power output and reduced module temperatures, offering similar efficiency to continuous cooling but with far lower water consumption, pump operation, and costs.

BP and Iberdrola say their 25 MW green hydrogen project in Spain is nearing commissioning, while Moeve has approved a final investment decision for a 300 MW project in Spain.
