Batteries

Puerto Rico has reached 1.3 GW of residential solar and 185,000 residential batteries, with Wood Mackenzie expecting three more GWh of residential storage by 2029. Utility-scale solar and storage projects are gearing up, as described by an attorney with McConnell Valdés.

Spain’s Ministry for Ecological Transition says a new €2 billion ($2.3 billion) funding package is designed to accelerate industrial capacity, expand renewable deployment, and boost the country’s long-term energy resilience.

A US research team has developed all-solid-state sodium batteries that retain performance down to subzero temperatures. The systems utilize a special chloride-based solid-electrolyte-coated cathode.

In a major milestone for the two-year-old Series A startup and the broader stationary energy storage sector, US-based Peak Energy has signed a supply agreement potentially worth more than $500 million.

Last year, German network operators received 9,710 connection requests for battery storage systems planned for commissioning at the medium-voltage level. These requests correspond to a total of 400 GW/661 GWh. At the transmission network level, large-scale battery storage projects with a combined capacity of 51 GW have already been approved for development in the coming years.

While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far faster than expected. Solar PV, wind power, and battery technologies have already reached price levels that models once placed many decades ahead – a misplaced pessimism that risks misdirecting billions in climate investment and could distort long-term defossilization strategies.

The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.

The PPA price for pure photovoltaic projects has fallen by 20% over the past year, making such contracts less competitive. However, clear structures for bankable hybrid PPAs are now beginning to take shape, says Pieter van der Meulen, Senior Account Manager at LevelTen Energy, in an interview with pv magazine.

From ESS News China Petroleum & Chemical Corporation (Sinopec) and South Korea’s LG Chem have signed a joint development agreement to advance key materials for sodium-ion batteries, as the technology moves closer to mass commercialization. Under the agreement, the two companies will collaborate on developing cathode and anode materials for sodium-ion batteries, targeting applications in […]

The Chinese firm says its new EnerCube product is designed for commercial and industrial applications. It has a capacity of 2,250 kWh.
