Climatic trends, extreme conditions and sea level rise are already hitting many of Australia’s ecosystems, industries and cities hard. As climate change intensifies, we are now seeing cascading and compounding impacts and risks, including where extreme events coincide. These are placing even greater pressure on our ability to respond.

Elsewhere, Chinese researchers have synthesised ultrafine Pd100-xCux nanodot-modified TiO2 photocatalysts that display optimised energy barrier for interfacial hydrogen desertion, which reportedly exhibits excellent H2-evolution activity and stability, and Mitsubishi Heavy Industries has presented its plans to establish the Takasago Hydrogen Park, calling it the world’s first centre for validation of hydrogen-related technologies, from hydrogen production to power generation.

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.

Two industry experts have provided analyses of the current polysilicon price scenario in a chat with pv magazine and both agreed that polysilicon demand is still growing faster than supply. The price may decrease starting from the second quarter and reach more reasonable levels by the end of the year.

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.

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.”

Tindo Solar, Australia’s only solar panel manufacturer, has launched its first module designed specifically for utility-scale projects, the 545W Karra module. Australia-made, the module boasts a 23.1% cell efficiency with a low cell-to-module loss rate of 0.07%.

British analyst GlobalData has predicted residential and commercial rooftop panels will not return to a declining price trend until next year, with post-Covid logistics headaches the cause, rather than a polysilicon shortage.

TOPCon solar modules will gain more market share if their average efficiency, already higher than that of PERC panels, continues to improve, according to Stefan Glunz, PV research chief at Germany’s Fraunhofer Institute for Solar Energy Systems ISE. In an upcoming pv magazine webinar on the potential of TOPCon tech, Glunz will show how to reduce costs and increase efficiency.

The U.S. Department of Energy’s Ames Laboratory launched a new catalyst based on nitrogen and carbon to extract hydrogen from hydrogen storage materials at mild temperatures and under normal atmospheric conditions. Furthermore, South African President Cyril Ramaphosa said that the country is working on attracting new investments in electric vehicles and hydrogen and Norwegian consultancy and classification society DNV launched, together with 18 industry partners, a new Joint Industry Project (JIP) to enhance the standardisation for hydrogen production systems that use renewable energy-powered electrolysis to produce green hydrogen.
