Australian oil and gas giant Woodside is continuing its exploration of renewable energy, partnering with United States-based concentrated solar power entity Heliogen to build a 5 MW solar thermal demonstration plant in California which is expected to be capable of delivering clean energy with nearly 24/7 availability.

Scientists in the United States have developed a method to compare the performance and number of defects in different perovskite cell materials. Based on simulations and work with prototype materials, the group finds that all-inorganic materials have higher potential efficiency than their more widely researched organic-inorganic counterparts.

Fortescue Future Industries has revealed it will partner with North American hydrogen technology company Plug Power to build the world’s largest green energy infrastructure and equipment-manufacturing facility in Central Queensland.

The ESS battery systems have a prescribed design life of 25 years, but the battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance.

Closed-loop pumped-hydro storage offers more chances to minimise environmental effects on water sources and overcomes the problem of finding suitable sites. According to an Australian research team, closed-loop systems could prevail on open-loop systems in the future and this trend is confirmed by another group of scientists from the United States.

Multiple factors affect lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.

As solar deployment increases, concerns about price cannibalisation continue to be more and more relevant. Large-scale solar generation during midday hours may result in curtailment or unprofitable wholesale power prices. As supply increases, the economic viability of solar PV projects could fall into question.

Buildings are considered to be a major driver of emissions. In addition to the predicted billions of square meters of space that will be built across the world over the next decade, most developments standing today will still be around in 2050. Thus, retrofitting existing structures is seen as a key sustainability target. In the fourth quarter of 2021, pv magazine’s UP Initiative will focus on the role that solar and energy storage can play in greening the world’s urban spaces.

U.S. start-up EnerVenue has secured funding to build a gigafactory to produce nickel-hydrogen batteries for large scale renewable and storage applications. The battery has an efficiency ranging from 80 to 90%, depending on the cycle rate, and its energy density per square foot is equal to, or better than lithium-ion batteries, according to the company.

The sustainability claims of a crowdfunded ‘e-textile’ range launched by Art by Physicist are borne out by the fact each garment will be printed on demand.
