Europe’s race to decarbonize its energy system has intensified under mounting geopolitical pressures. This week, the European Commission approved sanctions banning new gas and LNG imports from Russia, reinforcing the urgency to diversify supply and accelerate the green transition.

The U.S. Department of Energy (DOE) has canceled $700 million in federal battery and manufacturing grants, marking the second wave of funding reversals this month and signaling a more stringent approach to industrial subsidies.

Tesla has issued a recall for 12,963 vehicles in the United States after identifying a potential battery connection defect that could cause sudden power loss while driving, according to the National Highway Traffic Safety Administration (NHTSA).

VSPARTICLE’s nanoporous catalyst layer technology has passed peer-reviewed validation, confirming performance benchmarks that could mitigate one of the most pressing bottlenecks in proton exchange membrane (PEM) electrolyzer scaling—the scarcity of iridium.

MIT researchers have achieved a tenfold increase in the energy storage capacity of electron-conducting carbon concrete (ec³), a material capable of turning buildings, bridges, and pavements into functional energy storage units.

In addressing the increasing need for efficient energy storage solutions, a recent study introduced an offline lithium-ion battery repair system that employs a dynamic strategy and hybrid topology, aiming to tackle common issues such as battery inconsistency, high costs, and single control methods in lithium battery packs.

As renewable energy penetration rises, balancing intermittent generation with reliable grid services remains a pressing challenge. Subsurface pumped energy storage (SPES) is emerging as a versatile solution, offering kilowatt-to-megawatt-scale power output from a single well while achieving storage densities over 30 times greater than conventional pumped hydro storage.

In a move that could test the commercial viability of natural hydrogen exploration in Canada, MAX Power Mining Corp. has defined the first deep-drilling target specifically designed to locate naturally occurring hydrogen gas within the country’s subsurface.

The U.S. energy storage sector recorded its strongest quarter on record in Q2 2025, adding 5.6 gigawatts (GW) of new capacity, according to the latest U.S. Energy Storage Monitor from the American Clean Power Association (ACP) and Wood Mackenzie.

Chile’s government has announced a recalibration of its green-hydrogen ambitions, signaling a shift in strategy as international demand softens. Speaking…
