Scientists in Czechia have conducted a techno-economic analysis of a green hydrogen production system powered exclusively by photovoltaic and wind energy. The system uses surplus energy for water treatment and, according to its creator, can achieve a levelized cost of hydrogen of $3.12/kg.

SolarDuck and Tokyu Land have installed a floating solar demonstration unit in Japan. This project is billed as the nation’s first offshore floating solar power plant on the surface of the ocean and will be used to power electric vehicles and boats.

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.

State-owned utility Egyptian Electricity Holding Company is requesting expressions of interest for the design, building and operation of a 8.2 MW solar plant and 2 MW/4MWh battery energy storage system, located at the site of an existing microgrid in western Egypt.

An “Australian first” demonstration of aggregated flexible demand in residential settings will be rolled out in South Australia, with the state’s principle electricity distributor to deliver smart energy upgrades for 500 households as part of a pilot program to coordinate power usage and support the grid.

A collaborative project led by German battery supplier Varta aims to develop industrial-scale sodium-ion battery technology. The final product of the three-year, €7.5 million ($8.08 million) project will be a small series of round cells for electric vehicles and stationary storage systems.

Sunrun, a US-based residential solar installer, says nearly 1,800 customers have already signed up to its PowerOn Puerto Rico virtual power plant (VPP). The program deploys stored solar energy from customers’ batteries to the grid, preventing power supply shortfalls on the island.
