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.

The transaction, for which Shell did not reveal the purchase price, will see the energy company pick up a U.S. project development pipeline which reportedly runs to more than 18 GW of solar generation and energy storage capacity across 26 states.

Developed by a spin-off of Dutch research institute TNO, the battery is claimed to offer higher energy density, longer lifespan and increased safety compared to conventional lithium-ion batteries. It will initially be applied in wearables and electric cars.

Dutch renewables company Photon Energy has announced it will build “the world’s largest” solar-plus-storage project to date, teaming with Australian technology provider and project developer RayGen Resources to develop a facility that will deliver 300 MW of solar generation and 3.6 GWh of energy storage.

Vattenfall is leading a Dutch consortium in a research project to assess whether agrivoltaics is also compatible with strip cropping. The company’s head of Solar Development NL, Annemarie Schouten, spoke with pv magazine about the first 0.7 MW pilot project under development in the northern Dutch province of Flevoland.

Operated by Gasunie, the underground storage facility is located near Veendam in the province of Groningen and should be fully operational in 2026. Tests will be run until spring 2022.

Photon Energy reported raised revenue from sales of electricity in the second quarter of the year, compared with 12 months earlier, but said grid hold-ups at 14.6 MW of solar projects Down Under had affected performance.
