The conversion of solar energy into hydrogen energy represents a promising and green technique for addressing the energy shortage and reducing fossil fuel emissions. A research team from City University of Hong Kong (CityU) recently developed a lead-free perovskite photocatalyst that delivers highly efficient solar energy-to-hydrogen conversion. Most importantly, they unveiled the […]
When record rainfall caused flooding in south-east Queensland last February, Steve McLean’s solar installers stayed off their roofs, blowing a $60,000 hole in his company’s budget and setting back what could to have been another record year for his business. “If we didn’t do a system for five weeks, you can imagine nobody else did. […]
Behind the “billionaire biffo” between Mike Cannon-Brookes and Andrew Forrest over the future of Sun Cable is a project that analysts are calling “visionary” but also “extremely ambitious”. In Australia’s first major business story of the year, Sun Cable was placed into voluntary administration on Wednesday. It signaled the company could not make debt payments […]
A novel technique called Underground Gravity Energy Storage turns decommissioned mines into long-term energy storage solutions, thereby supporting the sustainable energy transition. Renewable energy sources are central to the energy transition toward a more sustainable future. However, as sources like sunshine and wind are inherently variable and inconsistent, finding ways to store […]
Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable medical devices. University of Illinois Urbana-Champaign researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by any existing battery design. […]
Perovskite solar cells (PSCs) can be made with low-cost materials, are highly efficient, can surpass traditional silicon solar cells, and have the potential to revolutionize renewable energy. However, one of the current drawbacks preventing their widespread use has is their lack of operational stability. Now, scientists at EPFL and Sungkyunkwan University in […]
