Hydrogen-producing rooftop solar panels nearing commercialisation

KU Leuven researchers have developed rooftop panels that capture both solar power and water from the air. Like traditional PV modules, hydrogen panels are also connected, but via gas tubes instead of electric cables. The researchers are now preparing to bring the tech to the mass market via a spinoff company.


Novel redox flow battery paves way for low-cost storage

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

Latest advances in sodium-ion battery research

Qingdao University researchers have synthesised high-performance titanium dioxide-based anode materials with excellent cycling stability, while German scientists have used operando techniques to observe how solvated sodium ions embed themselves in electrodes.

Globalised supply chains saved $103 billion in solar panel production costs

A new study has calculated that the globalised PV module supply chain has saved billions for PV installers in Germany, the US and China. It also found that if strong nationalistic policies that limit the free flow of talent and capital were implemented going forward, solar panel costs would be 20-25% higher by 2030.


UNSW researchers develop high yield, low cost, eco-friendly process to recycle Si-PV modules

A team of researchers from the University of New South Wales (UNSW) has proposed a cost-effective way to recycle silicon solar panels. Their process consists of module deframing, laminate shredding and material concentration using electrostatic separation, reducing their original weight by 2% to 3%.


NSW payments for hosting new transmission lines set to double

As it looks to replace its ageing coal-fired fleet and accommodate a growing share of renewables on its grid, New South Wales has pledged to nearly double the average payments landlords across the state receive for hosting high voltage transmission lines.


Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market

US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.

Wind, solar payback times under a year in some parts of world, says Rystad

Record energy prices, particularly in Europe, are driving demand for renewables and energy storage. That is changing the equation for utility solar and wind investment and shortening project payback times to under a year in some regions. Storage deployment, driven by recent policy developments around the world, is also expected to get a big boost through to 2030.

Sodium-ion battery anode made from toxic hogweed

Russian researchers have transmuted poisonous Sosnowsky’s hogweed into high-grade anode material for sodium-ion batteries. The obtained material has a Coulombic efficiency of 87%, which is on par with the best reported results for hard carbons synthesised from other raw materials.

Off-grid solar continues to expand

The off-grid solar sector has shown resilience in the face of pandemic-related challenges, with 70 million people gaining access to electricity from early 2020 to the end of 2021. However, the ability to pay for solar energy kits has taken a hit.
