Hydrogen buses less efficient than battery models

Italian researchers have compared the performance of hydrogen and electric buses in northern Italy. Meanwhile, Australian company Worley has collaborated with Princeton University to devise a 10-point action plan for Europe’s renewable hydrogen sector.


Flexible indoor perovskite solar cell achieves 32.5% efficiency

Italian scientists have developed a flexible indoor perovskite solar cell with 32.5% efficiency. Their design uses a PET substrate combined with a tetrabutylammonium bromide layer over the perovskite absorber. This additional layer effectively reduces defect density and enhances the stability of the underlying 3D perovskite structure.

Melbourne researchers target MW scale with proton battery technology

A team of engineers at Melbourne’s RMIT University have developed a rechargeable ‘proton battery’, claiming the technology has the potential, with further development, to store more energy than currently available lithium-ion batteries.


Italian startup offers solar kits packed in barrels

Italian manufacturer Barrel claims that solar kits packed in barrels are ideal for remote areas and conflict zones. Its standard packages consist of 6 kW solar modules, a 5.6 kW single-phase hybrid inverter, and 3.55 kWh of lithium battery energy storage capacity.

Japan’s Inpex secures 50% share in Enel’s Australian solar portfolio

Japanese oil and gas giant Inpex has struck a deal to buy 50% of Italian utilities giant Enel Group’s Australian renewable energy platform, Enel Green Power Australia, handing it joint control of a solar farms portfolio that includes 254 MW of installed capacity and another 170 MW of renewables under construction.

Swiss team sets record solar-to-hydrogen rate

Researchers from Switzerland’s École Polytechnique Fédérale de Lausanne have unveiled a new solar dish plant design, while Plug Power has delivered its first electrolyser system to Europe.

Battery hydrogen vs. battery flywheel

Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels combined with batteries could be the cheapest option for power smoothing.

Customisable sticker to turn solar panels into advertising billboards

An Italian startup has created a fully recyclable sticker that can be used to cover solar panels on rooftops or facades. It replicates high-definition images that can help to improve the aesthetics of solar arrays or turn PV facades into advertising billboards.

Weekend read: A sustainability swan song

Pioneering PV researcher Martin Green has received an abundance of accolades over his 50-year career of fundamental solar research with teams at the University of New South Wales (UNSW). That contribution was further recognised on Sept. 26, when he picked up the WCPEC-8 Award in Milan, Italy. Green spoke with pv magazine about the role of technologies such as PERC cells and his efforts to advance non-toxic thin film semiconductors for the tandem cells of the future.

FFI teams up with European heavyweight on green hydrogen for Australia, Latin America

Australian green hydrogen developer Fortescue Future Industries and Italian gas and electricity giant Enel are set to partner on making green hydrogen cost-competitive with fossil fuel alternatives this decade.
