The Hydrogen Stream: US startup unveils nanoparticle-based green hydrogen tech
SunHydrogen has provided a first look at the prototype design for its forthcoming nanoparticle-based green hydrogen technology, and Plug Power has secured a 5 MW electrolyzer order from Lhyfe. A Chinese-US research group, meanwhile, claims to have achieved a highly stable saline water electrolysis using Rhodium nanocrystals.
Improving n-type TOPCon solar cells
Scientists in China have studied the formation of contacts in tunnel-oxide passivated contact (TOPCon) solar cells, and the role of high-temperature annealing processes on the quality and performance of cells. Their findings could open up pathways for scientists looking to squeeze even more efficiency out this rapidly growing cell technology.
Photovoltaics for inland shipping vessels
Dutch researchers have looked at how PV systems could be used to power bulk vessels for inland shipping. They found that 7.18% and 5.78% of the energy demand of container ships and bulk vessels can be respectively supplied by solar panels.
Shipments of module-level power electronics could hit 100 GW by 2026
IHS Markit said it expects the United States, Germany, and the Netherlands to be the top three markets for cumulative shipments of module-level power electronics in the 2022-26 period. Cumulative shipments are set to hit almost 100 GW by 2026.
IEA says global heat pump installations to hit 600 million by 2030
The International Energy Agency (IEA) says that the deployment of 600 million heat pumps by 2030 could cover 20% of the annual heating requirements of buildings throughout the world.
Solar perovskite tandems and potential-induced degradation
Scientists have found that perovskite solar cells and perovskite-silicon tandems might be vulnerable to potential-induced degradation. They exposed tandem cell devices to PID stress and found that they lost as much as 50% of their initial performance after just one day.
Hydraulic robotic cleaning solutions for ground-mounted solar plants
France’s AX Solar Robot has unveiled two battery-free, hydraulic-powered cleaning solutions for ground-mounted PV plants. It is also distributing a modular battery-powered solution suitable for rooftop installations.
Essential tips for successful installations
Installing and servicing a residential solar setup requires know-how and expertise, from rooftop to hybrid inverter, and increasingly, home storage setup as well. In this pv magazine Webinar, we’ll look at Sungrow’s just released Power Guide, a handbook of tips that tackle commonly asked questions and requests from installers and the industry, with all the answers and support.
The Hydrogen Stream: Condensed hydrogen on smooth surfaces can sharply exceed liquid hydrogen density
A German-US research team has shown that hydrogen condenses on smooth surfaces at a very low temperature, forming a super-dense monolayer that reduces the volume to just 5 liters per kilogram of H2. Dutch researchers, meanwhile, have published a new study on hydrogen storage in porous rocks, and Itochu said it is moving forward with hydrogen plans in Japan and South Africa.
A game-changer for PPA markets
Extreme volatility and high prices recorded on energy markets, coupled with inflation, and soaring interest rates are impacting long term power purchase agreements. Still there is a way to the success and signing of contracts.
