Researchers from the University of Wollongong have manufactured a nanomaterial that acts as a superior cathode for room-temperature sodium-sulfur batteries, making them a more attractive proposition for large-scale energy storage.
Researchers have made a finding they say could vastly simplify and reduce the production cost of perovskite solar cells. Working with mixed halide perovskites, the group found a disordered chemical composition can improve device efficiency.
Scientists at Princeton have found solar and wind energy offer the added environmental benefit of reducing water usage, by comparison with hydroelectric dams. Their findings, say the researchers, could have a positive impact on groundwater sustainability in drought-prone regions such as California, where they conducted a case study.
The Smart Energy Hub can operate in electrolysis mode to store renewable energy as hydrogen, or in fuel cell mode to produce electricity and heat from previously produced hydrogen or methane. Its developers are the French Alternative Energies and Atomic Energy Commission and start-up Sylfen.
Meet Afnan Hannan, CEO and co-founder of Okra Solar, an Aussie startup looking to eradicate energy poverty using solar minigrids that has already been recognised with a global sustainability award and a best IoT startup award.
Research from the United States has demonstrated how PV technology can be used to kill cancer cells. Although still at an embryonic stage, the findings of the study and initial test results suggest solar power could be an effective tool in relation to light-activated fluorescent dyes for disease diagnosis, image-guided surgery and site-specific tumor treatment.
