Native American lands boast serious PV potential in the United States but getting projects off the ground hasn‘t always been easy. Different tribes are willing to take power generation into their own hands and the landscape could be shifting, thanks to funding from the US Inflation Reduction Act (IRA) and other programs.

Portable solar generators are making their way from the fringes of solar and energy storage to become a mainstream consumer item. The rise has been charged by a range of factors that have created massive brands. Where did the sector emerge from, who was buying before, who is buying now, and what’s next? Tristan Rayner reports.

The Japan Organization for Metals and Energy Security (Jogmec) and Germany’s H2Global Foundation have agreed to cooperate on clean hydrogen, while officials from Japan and South Africa met this week to discuss hydrogen collaboration opportunities.

Zaha Hadid Architects has unveiled the world’s first green hydrogen refueling network for recreational boats at marinas in Italy, while a German-Czech consortium has announced the development of a drivable hydrogen motorcycle.

H2 Green Steel has secured funds to produce green steel in Sweden, while ZeroAvia has locked down support to develop a mobile liquid hydrogen (LH2) refueling truck for heavy-duty applications.

Diesel generators have been the workhorse of disaster relief for decades but as the frequency of extreme weather events rises, so do calls to decarbonize the emergency response. Sustainability may not be the only benefit to using solar in a crisis, as pv magazine discovers.

Scientists have used remote sensing to analyze the effect solar farms have across 116 sites worldwide. They found that the cooling effect is higher during the daytime, with albedo decreasing by 0.016 for most facilities.

Thresholding methods have commonly been used to characterize the soiling accumulated on glass coupons. Researchers led by the Sapienza University of Rome have identified 16 automatic thresholding methods that may be used for analyzing soiling on PV panels.

Solar Insure tells pv magazine USA that the financial stability of rooftop solar companies in California is now in question. Despite this, a state appeals court recently reaffirmed a number of anti-solar decisions.

A global research group has designed a novel PV module cooling system based on multiple cooling sources. The proposed system was able to reduce a PV system temperature by up to 16.7 C and increase power output by over 9%.
