Technology and R&D

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.

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.

Australian concentrated solar thermal power company Vast Solar has been shortlisted as a finalist for BNEF’s Pioneers 2022 program.

Conceived by scientists in China, the battery was built with a special hydrogel electrolyte made of polyacrylamide (PAM), zinc sulfate (ZnSO4), glycerol (GL), and acetonitrile (AN). The device showed high cycling stability of over 3,000 cycles, a high reversibility thanks to a Coulombic efficiency of up to 99.5%, and electrochemical performance of 185 mAh·g over 10,000 cycles.

Researchers at the Indian Institute of Technology Bhubaneswar have developed a solar power system that can be easily moved between farms to pump water for irrigation. The kit comprises solar panels and an inverter to power a surface-mounted pump.

Two of Australia’s most prominent energy players, Fortescue Future Industries and oil and gas giant Woodside Energy have been included on a shortlist of potential development partners for a proposed 600MW green hydrogen production and export facility planned for New Zealand’s South Island.
