Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a.

American researchers are proposing to use steel zip ties to attach solar modules to fences in animal farms as a low-cost racking solution for agrivoltaic applications. They found the proposed approach is technically and economically viable, provided careful wind load tests are conducted on the fences.

A Canadian research group has applied new guidelines for ground coverage ratios to 31 locations in Mexico, the United States, and Canada. It found the new formulae show that the factors affecting inter-row energy yield loss are highly dependent on latitude.

Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.

Scientists in China and Canada have developed an additive that forms covalent bonds with the organic materials in a perovskite solar cell, leading to fewer defects and greatly reduced degradation. Cells treated with the additive maintained 98.6% of their initial performance after 1,000 hours in testing. Xlynx Materials, a company spun out of the University of Victoria in Canada, is making the material available for further commercial trials.

Japan has announced plans to invest $150 billion in hydrogen over the next decade, while Malaysia has revealed that it will invest in solar and hydrogen under a new energy roadmap. Separately, Kansai Electric Power and Canada’s ATCO have agreed to collaborate on a feasibility study for green hydrogen supplies.

Plug Power has revealed plans to develop three green hydrogen production plants in Finland, while Statkraft is set to increase its investments in the German hydrogen market.

The perovskite solar race is heating up, with a cue of manufacturers forming to test products at the US Department of Energy’s (DoE) PV commercialization facilities, and academics on both sides of The Pond announcing new advances in recent months.

EVLO Energy Storage’s latest battery energy storage system (BESS) product, EVLOFLEX, is a fully integrated solution with configurable energy for 1.65 MWh, 2 MWh, or 2.5 MWh.
