A report published by IRENA hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, found a study using an idealised grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology.

The world has installed its first terawatt of hardware on earth to generate electricity directly from the sun.

Scientists from the Massachusetts Institute of Technology have developed a system that can be operated at a voltage of around 12V, with a 95% recovery rate for lost power after cleaning. The waterless system can be operated automatically via an electric motor.

The International Renewable Energy Agency has outlined a series of technical considerations for green hydrogen tracking systems. According to the document, a degree of flexibility should be taken into account in the short term to ensure that the nascent green hydrogen market can develop.

Sodium-ion batteries are emerging as a viable alternative to lithium-ion technology. Industrial heavyweights CATL and Reliance Industries, following the acquisition of UK-based sodium-ion specialist Faradion, are bent on bringing the technology out of the lab and into mass production. Against a backdrop of soaring prices and predicted shortfalls of lithium-ion battery materials, sodium-ion chemistry has never been more tantalising.

The London-based analyst has published a series of clean tech predictions for the year which also highlighted the rising proportion of sub-5MW solar projects in the global market, and cheaper clean energy financing costs even as panel prices continue to rise.

With 90% of world economies committed to net zero targets, the disruptive nature of the energy transition is becoming clear. Climate targets require us to triple renewable energy capacity by 2030, phase out coal by 2040, end fossil fuel subsidies, and ensure support for a just transition. While hydrogen is sure to be a key technology in this energy transition, the exact role it will play is not yet clear, reports Felicia Jackson.

US analyst Clean Energy Associates made some notable predictions in its Q4 survey of the world solar manufacturing market, including echoing predictions made elsewhere that the new polysilicon production capacity coming online now will help arrest the spike in solar panel prices.

Fortescue Future Industries says the first electrolysers to be manufactured at the facility, early next year, are earmarked for use in Queensland at FFI’s planned green-hydrogen-to-ammonia project on Gibson Island.
