Aurora Energy Research says in a new report that maximum green hydrogen project profitability could be achieved when solar and wind power plants are combined with electrolysers.

Chinese battery manufacturer BYD has launched an expanded portfolio of energy storage systems designed for the commercial and industrial solar markets. At The smarter E in Munich last month the company also provided a sneak peak at a new high-voltage storage system expected to be launched later this year.

German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron. They confirmed that the performance losses are caused by a bulk defect in the material, and found that the right combination of light and temperature can “heal” earlier damage and even lead to small improvements in overall cell efficiency.

The hydrogen electrolyser subsidiary of German giant Thyssenkrupp has opened a new office in Perth, Western Australia in a bid to capture some of the region’s green hydrogen frenzy.

German researchers have developed a new shape-stabilised phase change material with the ability to store up to five times more thermal energy than commercially available phase change materials (PCMs).

The S5-EO1P(4-5)K-48 series off-grid PV inverter has an efficiency of 96.7% and supports parallel operation of up to 10 units, which allows for a system capacity of up to 50 kW. According to the manufacturer, the device is compatible with all top-tier brands of lithium-ion and lead-acid batteries.

Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.

West Australian company Vulcan Energy Resources, backed by mining magnate Gina Rinehart, has signed a geothermal heat energy offtake agreement with a major German energy supplier, MVV Energie. Vulcan is planning to eventually secure a lithium supply from the same deep brine source in the Upper Rhine Valley, Germany.

Bosch’s new solid oxide fuel cell prototype has an electrical efficiency of more than 60% and an overall efficiency above 85%. It also has a targeted power output of 10 kW and can produce up to 3 kW of thermal energy.

UK-based analyst Exawatt and Germany’s Nexwafe published a white paper this week that takes a close look at the current state of PV manufacturing worldwide, and how Nexwafe’s innovative wafer production tech might fit into it. They said that if the potential of its Epiwafer can be realised, the PV industry may yet see “another revolution in wafer manufacturing.”
