Energy Storage

Sinovoltaics has released its latest energy storage manufacturers ranking report, based on balance sheet assessments and publicly available financial information. It lists US-based Tesla as number one, followed by South Korean’s LG Energy Solution, Taiwan-based Kung Long Battery, China’s Mustang Battery, along with US-based Solid Power in the top five.

The authorities in Ireland have opened a €20 million ($21.5 million) fund for energy research and innovation. It will support projects contributing to the nation’s clean energy transition, such as heat decarbonization and energy storage.

UK scientists have proposed a way to combine photovoltaic-thermal energy with Stirling engines and battery storage in residential buildings. Despite the high upfront costs, they said the cost-effective hybrid co-generation system could significantly reduce CO2 emissions.

The Japanese authorities selected 30 battery storage projects in the procurement exercise. The selected developers and plant owners will be awarded a 20-year fixed revenue.

BSES Rajdhani Power’s new 20 MW/ 40 MWh project is India’s first utility-scale, standalone battery energy storage system to secure regulatory approval under Section 63 of the Indian Electricity Act, 2003. The project is supported by a concessional loan from the Global Energy Alliance for People and Planet (GEAPP).

Modeling shows that shifting just one-third of the electricity consumption of commercial and institutional buildings in Australia to the middle of the day, coinciding with peak solar supply, would create almost 12 GW of new peak capacity in the National Electricity Market.

A group of Chinese researchers has made a first attempt to integrate pumped hydro with compressed air storage and has found the latter may help the former to better deal with large head variations.

The US Department of Energy says it is aiming for “clean” hydrogen production costs of $2/kg by 2026 and $1/kg by 2031.

A study led by Russia’s Skoltech and China’s HPSTAR suggests that rubidium and cesium additives could improve the efficiency of hydrogen batteries. Researcher Dmitrii Semenok tells pv magazine that “it is a question of changing the approach to the search for promising hydrogen storage materials.”

New research from Sweden suggests that low platinum fuel cells for hydrogen vehicles, when scaled up for the same number of cells, may achieve similar or higher efficiencies compared to commercial fuel cells. Their modeling is expected to act as a bridge between material science research and vehicle implementation.
