Artificial intelligence (AI) can play a key role in combating climate change, including by application in the renewables industry. Dustin Zubke is watching this week’s International Conference on Learning Representations workshop to find out how, after the Addis Ababa conference was moved online because of the Covid-19 pandemic.
The cataclysmic bushfire season ravaging the nation is a reminder of the risk climate change poses to Australia’s economic and social prosperity. An international roadmap to freedom from fossil fuels by 2050 produced by the U.S.’ Stanford University says Australia needs another 280 GW of solar and tens of billions of dollars of investment to turn down the heat.
Researchers in Denmark have developed water-based nanofibers coated with a biological PV substance which can be easily injected into the body. The developers say excitable cells in the heart and brain could be regenerated by being electrically stimulated with the solution.
Researchers at Sweden’s Lund University have discovered a mechanism by which iron-based solar cells lose up to 30% of their charge. Understanding how the loss occurs, say the researchers, will be the first step to closing the loophole and developing more efficient solar cells based on the abundant material.
An international team of economists says power-to-gas may already generate hydrogen at costs competitive with fossil fuel power plants in Germany and Texas, provided certain production output levels are not exceeded. If medium and small power-to-gas is competitive, large-scale should be viable by 2030.
The water-based battery relies on a reversible chemical reaction that stores electrons in the form of hydrogen gas. Despite encouraging first results, the prototype developed by the research team now needs to be further developed.
Mimicking a compound eye of a fly, Stanford University scientists have packed tiny perovskite cells into a hexagon-shaped epoxy resin scaffold, improving the material’s durability when exposed to moisture, heat and mechanical stress in a breakthrough that may open the door to the awaited improvement in perovskite’s operational stability.
Scientists at the Department of Energy’s SLAC National Accelerator Laboratory have published research revealing unusual atomic motions in perovskite materials exposed to light. The discovery, says Stanford, could prove crucial to further increasing the efficiency potential for perovskite solar cells.
