Fraunhofer ISE produces hydrogen via PEM electrolyser with seawater
Fraunhofer ISE scientists have optimised a technical concept for a hydrogen plant at sea. They claim that their design is “technically and economically viable.”
Study shows n-type bifacial TOPCon cells more prone to degradation than p-type
Dutch scientists have reported higher degradation risk for n-type TOPCon cells with EVA encapsulant due to potential moisture degradation. Front-side metallisation makes n-type cells more vulnerable than p-type cells, according to damp heat tests.
Weekend read: ‘Solar crime’ on the rise
With copper prices rising, inflation driving up the cost of living, and organised criminal gangs stepping up operations in the United Kingdom and across Europe, solar project owners need to be more conscious than ever of security, reports Max Hall.
Plug-and-play PV system for garden fences
German PV product supplier Green Akku says that its new PV system can be vertically attached to fences. It reportedly generates more solar power, even in winter.
Hybrid wind-solar power system for residential applications
Dutch startup Airturb has developed a 500 W hybrid wind-solar power system featuring a vertical axis wind turbine and a solar base hosting four 30 W solar panels. The system can be used for rooftop or off-grid applications.
Battery hydrogen vs. battery flywheel
Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels combined with batteries could be the cheapest option for power smoothing.
Final panel installed as Australia’s largest solar farm nears full capacity
Three years after French renewable energy developer Neoen first broke ground at the site of its Western Downs Green Energy Hub in Queensland’s Western Downs region, the last of the more than one million panels has been installed as the 400 MW solar farm nears 100% completion.
SMA unveils new commercial battery storage solution
Germany’s SMA has developed a modular lithium-ion solution for commercial storage applications. It comes in two versions, with capacities of 32 kWh and 56 kWh. The two variants feature SMA Sunny Tripower Storage X battery inverters, with up to 8,000 complete charge cycles.
Fluence introduces utility-scale battery for transmission networks
Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets. It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.
Altech reveals 1 MWh sodium chloride battery GridPack design
Western Australian battery technology company Altech Batteries has included “game-changing” sodium chloride technology in the design of its new battery 1 MWh GridPack which is expects will be up to 40% cheaper to produce than the dominant lithium-ion alternatives.
