Technology and R&D

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.

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.

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.

Western Australian energy storage company VSUN Energy has inked a deal with aspiring renewables developer North Harbour Clean Energy which will see the two companies collaborate on the development and installation of vanadium redox flow battery projects and vanadium electrolyte supply.

The World Intellectual Property Organisation says China accounted for 69% of the patents filed for transport-related fuel-cell tech in 2020, with road transport significantly dominating applications.

Green Gravity, a startup proposing to use old mine shafts for gravitational energy storage, has raised $1.4 million in its first formal capital raise. The company, headed up by former BHP executive Mark Swinnerton, is now finalising its concept engineering in preparation for its demonstration plant. “I think we’re going to get the ‘and’ here,” Swinnerton told pv magazine Australia, referring to the technology’s potential to provide low cost firming (and more) by using yesterday’s infrastructure to solve today’s problem.
