Electric vehicle batteries are packed with energy, with additional battery density and efficiency working to quell range anxiety for drivers. But with that capability lingers a concern from some that EVs may pose a fire risk and a challenge for first responders in the event of accidents. Western Australia’s Professor Ray Wills from Future Smart Strategies bought his first EV in 2012 and argues that in terms of safety, EVs remain an easily superior vehicle, and even the tiny fire risk that exists is an ever-diminishing issue.

Rystad Energy has joined BloombergNEF with a significant forecast for grey and blue hydrogen off the back of Russia’s invasion of Ukraine. According to the analysts, the impact of the war has sent prices of fossil fuel-tied forms of hydrogen production surging, leaving the gradual but consistent downward price trend of green hydrogen now looking remarkably competitive.

Analyst Wood Mackenzie has predicted soaring demand for electric vehicle devices will ensure supply will not keep pace with demand until some point in 2023.

Nextracker has today launched its new terrain-following, single-axis tracker built specifically for projects on sloped, uneven, and challenging sites. Nextracker believes its new NX Horizon-XTR line will be market-shaping, especially in countries like Australia where opposition to land disturbances of utility-scale solar is growing.

The new product is part of the company’s HiKu6 series based on 182mm wafers. Its temperature coefficient is 0.34% and its electrical characteristics are claimed to be compatible with the most common photovoltaic inverters thanks to current values below 14A.

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.
