With some of the highest rooftop solar PV penetration in Australia the outback town of Alice Springs will soon play host to the Northern Territory’s first resident Virtual Power Plant with the project partners exploring how best to bolster the reliability of the local grid and pave the way for the increased penetration of renewable energy.

CHN Energy has linked a 100 MW floating PV plant to an existing 4.1 MW tidal energy system in China’s Zhejiang province. The tidal power station was commissioned in 1980 and is the fourth-largest system of its kind in the world.

An international research team has proposed the use of water from high-altitude rivers and regenerative braking in electric trucks to store electricity for reuse in power networks, or for transport purposes.

New South Wales transmission network owner Transgrid has commenced construction on its section of the $2.3 billion Project EnergyConnect, the high-voltage electricity transmission interconnector that will link power grids across three states, unlocking gigawatts of planned renewable energy projects.

Aurora Energy Research says in a new report that maximum green hydrogen project profitability could be achieved when solar and wind power plants are combined with electrolysers.

Huaneng Group has finished building a 300 MWh storage project in Changzhou, in China’s Jiangsu province. The state-owned company has already started operating the facility, which is situated in a salt cavern.

Trina Solar will eventually start selling TOPCon and heterojunction products, even though it built its first large-scale TOPCon project four years ago. The company says it is now making progress on TOPCon module production, despite supply chain issues.

United States-based data company Global Energy Monitor has launched a new open-source tool that lists Australia’s large-scale solar plants alongside those from another 147 countries.

North Carolina State University (NCSU) has developed an energy-efficient strategy for room-temperature hydrogen release from liquid hydrogen carriers, which uses less rhodium. Elsewhere in the world, Airbus launched its Zero Emission Development Centre in the UK, Toshiba ESS teamed up with Fusion Fuel to target Australian and European markets, and Corfo signed agreements to finance three renewable hydrogen projects with GNL Quintero, iCAP, and Air Liquide in Chile.

JA Solar said the smallest solar panel in its new n-type product line has a power output of 435 W and a power conversion efficiency of 22.3%. The largest module in the series has an efficiency rating of 22.4% and 625 W of nominal power. Their temperature coefficient is -0.30% per degree Celsius.
