Ibis Power has developed a rooftop system that combines solar with wind turbines designed for medium-sized structures and high-rise buildings. It claims its PowerNEST system can produce six to 10 times more energy than standalone rooftop solar. The company has already installed five projects in the Netherlands.

Australia-based energy investment manager Quinbrook Infrastructure Partners has sold a 49% stake in a massive $1.9 million (USD 1.2 billion) solar PV and battery energy storage project being developed in the United States to a Dutch pension asset manager.

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.

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.

The fire affected an area of around 5,000 square meters but did not damage the solar panels. The local fire brigade was able to control the fire in around two hours.

Researchers in the Netherlands investigated the potential for integrating power electronics in solar cells in the form of diodes, transistors, capacitors, and inductors. They believe that this kind of PV cell may initially find applications in PV-powered Internet-of-Things (IoT) devices and later, as the economy of scale kicks in, in large-scale applications.

With Australia’s presence felt strongly at the World Hydrogen Summit in Rotterdam last week, state governments are working to secure European markets through partnership agreements. Yesterday, New South Wales signed an initial agreement with Denmark which will see the distant pair support one another on matters of decarbonisation technology and trade. Just a few days earlier, Queensland’s government signed an MoU with the Netherland’s Port of Rotterdam to collaborate on opportunities to develop a hydrogen export supply chain.

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

The Genap Energy Cover uses HyET Solar Powerfoil thin-film solar modules, rated at 12.0% efficiency, for agricultural water storage and reservoirs, with an initial focus on the greenhouse and horticulture markets in the Netherlands. Genap said a 12kWp test setup had a generation density of 60W/m2, rising to 120W/m2 within a year, with an eventual target of 165W/m2.

A new underwater battery storage technology is coming from Netherlands-based Ocean Grazer to address the issue of offshore long-duration storage. The company’s Ocean Battery is touted as innovative yet simple, based on existing technology, and capable of enhancing marine life along the way.
