Australian maritime hydrogen company Poseidon Marine H2 says it expects to have a hydrogen-powered boat in Australian waters within the next 18 months after bringing on board the principal engineers from Dynamic Efficiency.

China’s largest state-owned grid operator and power utility plans to deploy the world’s biggest battery fleet and almost quadruple its pumped hydro storage by 2030, thus supporting the nation’s switch to renewable energy sources.

Scientists in Australia have developed an optimisation framework for building-integrated photovoltaics that allows the selection of design variables according to user preferences. Their model considers PV-related features such as tilt angle, window-to-wall ratio (WWR), PV placement, and PV product type, as well as objective functions and constraints such as the net present value and the payback period.

Silicon carbide (SiC) has promised inverter makers higher power density, higher efficiency, and a total bill of materials that comes in closer to its more established rival in silicon. Has SiC finally arrived? Tristan Rayner spoke to the people at the forefront of the wider-bandgap material to find out the back story and what’s next.

Fortescue Future Industries’ plans to establish a 2GW renewable energy infrastructure-manufacturing facility and a separate 50,000 tonne green hydrogen production facility in Queensland have reached a major milestone with state-owned network operator Powerlink agreeing to connect the project sites to its transmission network.

The deployment of standalone power systems in the National Electricity Market is expected to accelerate after the Australian Energy Market Commission this week published new rules allowing distributors to install the renewables-based technology in the five market jurisdictions.

British start-up Gravitricity secured funds from the UK Department of Business Energy & Industrial Strategy (BEIS) to build its second gravity-based storage project. The feasibility study is expected to be finalised by the end of this year.

Looking to deepen their hydrogen collaborations, the UK government last week spoke with Australian politicians. Meanwhile Australian engineer Worley has entered into an MoU with ABB and IBM to develop an “integrated, digitally enabled solution for facility owners to build green hydrogen assets more quickly, cheaply, and safely.”

BlueScope Steel, the country’s largest steelmaker, is refining and progressing its plans to decarbonise its steel making process – considered to be one of the greatest opportunities for green hydrogen use.

India and Australia have signed a letter of intent to cooperate on scaling up the manufacture and deployment of ultra-low-cost solar and “clean” hydrogen.
