The EU will be home to 30 million electric cars by 2030 and the European Commission is preparing tough targets for recycling these and other batteries. Yet the impacts of battery recycling, especially for the sizeable lithium-ion batteries of the electric cars soon filling our streets, has been largely unstudied. In a […]
A team of Nanyang Technological University, Singapore (NTU Singapore) researchers has designed a ‘smart’ device to harvest daylight and relay it to underground spaces, reducing the need to draw on traditional energy sources for lighting. In Singapore, authorities are looking at the feasibility of digging deeper underground to create new space for […]
A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid. The device resembles a large sponge that soaks up water but leaves contaminants – like lead, oil and pathogens – behind. To collect the purified water from the sponge, one […]
DNV, the independent energy expert and assurance provider has published the world’s first recommended practice (RP) for floating solar power projects following a collaborative joint industry project (JIP) involving 24 industry participants. The Recommended Practice (DNVGL-RP-0584) will provide commonly recognized guidance based on a list of technical requirements for accelerating safe, sustainable […]
In order to enable large-scale hydrogen production using solar energy, particulate photocatalysts are being researched as a simple and cost-effective solution to splitting water into hydrogen and oxygen. It is necessary to develop a photocatalyst that can efficiently use visible light, which accounts for a large part of solar energy, in the water decomposition […]
Materials called perovskites are widely heralded as a likely replacement for silicon as the material of choice for solar cells, but their greatest drawback is their tendency to degrade relatively rapidly. Over recent years, the usable lifetime of perovskite-based cells has gradually improved from minutes to months, but it still lags far behind the […]
