Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

Designed by Chinese provider Mibet, the mounting structure can be used for different crop types. The system offers a tilt angle of up to 30 degrees and can host either framed or frameless solar modules.

Western Australia-based Altech Chemicals’ plan to develop a high-grade alumina coating plant for lithium-ion batteries in Germany has taken a crucial step forward with the acquisition of an industrial site that could potentially house the facility.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm2, they achieved a record efficiency of 25.7% and high operational stability.

Fortescue Future Industries has acquired Williams Advanced Engineering for $310 million as it looks to capitalise on its critical battery technology to cut emissions from its mining vehicles. An offshoot of the Williams Formula 1 Team, Williams Advanced Engineering has already helped to develop an electric mining haul truck for Fortescue in 2021.

TOPCon solar cells are on their way to fully compete with PERC solar products, according to recent research from Germany’s Fraunhofer ISE. Efficiency gains for the TOPCon concept, however, are necessary to help it capture more market share, as production costs remain higher than those for PERC tech. A series of cost-driven strategies to make TOPCon modules advance were outlined in the study.

Fortescue Future Industries has taken another step toward its global green hydrogen ambitions with the signing of a Memorandum of Understanding with Germany polymer company Covestro for the equivalent of 100,000 tonnes of solar-sourced green hydrogen and its derivatives annually, starting as early as 2024.

While there are still many uncertainties as to the way in which hydrogen trade might evolve and change economic ties and political dynamics between countries, experts agree that green hydrogen can bring winds of change to the global energy arena. According to the International Renewable Energy Agency, significant geoeconomic and geopolitical shifts are just around the corner.

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.

Korea Zinc, non-ferrous metal smelting company, has agreed to invest $50 million in Energy Vault, a Switzerland-based gravity storage specialist, in order to use its tech to decarbonise its refining and smelting operations in Australia.
