United Kingdom-based SolarBotanic Trees will begin offering its solar trees in early 2023. The systems will use monocrystalline cells with an efficiency of up to 24%, encapsulated in a 3D shape.

German investment management company Aquila Capital has expanded its Antipodean asset base, inking a deal to buy a 220 MW/440 MWh portfolio of battery energy storage projects in South Australia from Spanish renewables developed Gransolar Group.

Solar-wind hybrid plants are rapidly becoming mainstream, and in booming markets like India and the US these hybrids are increasingly preferred to singular projects despite the higher installation cost. There is no shortage to the benefits of hybridisation, from a smoother power output profile to the cost saving of grid connection. But getting the balance right for new projects and retrofits remains a challenge. Blake Matich reports on this growing trend.

BMW Group said it is targeting the premium segment with its iX5 Hydrogen car, Topsoe revealed that it will invest US$267 million (AU$392m) to build the world’s largest SOEC electrolyzer plant in Denmark, and Bosch announced plans to invest US$200 million (AU$292m) in US fuel cell production.

Integrated clean home energy and smart appliances platform lets users run appliances on battery-stored solar energy in pre-determined time frames.

Dutch startup Elestor has secured funds to bring its hydrogen bromide (HBr) flow battery technology closer to commercial production. It said the system could achieve a levelised cost of storage below US$0.05/kW.

Germany has launched the world’s first operational hydrogen trains and US researchers have presented a novel design for a tubular PEM fuel cell. ABB and Hydrogen Optimized, meanwhile, have expanded their strategic ties and Slovakia has moved forward with a major gas-blending pilot project.

Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.

New Zealand and Germany have partnered up to provide NZ$2 million (AU$1.8m) each to three green hydrogen research projects, including one to develop more efficient anion exchange membrane electrolysers which promise to be cheaper and more sustainable to manufacture.

Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.
