Public concern about the safety of nuclear plants is driving research into ways to make the fuel rods more able to survive the kind of unexpected calamity experienced in Fukushima in 2011. Following the tsunami, hydrogen explosions were caused by the conventional zirconium-based fuel cladding interacting with the high temperature steam produced when the safety system failed and coolant water heated up. Writing for MIT, Leda Zimmerman describes … [Read more...]
EU Recovery Package mustn’t sideline Green R&D
Today (Wednesday 27 May) the EC releases its COVID-19 Recovery package and Multiannual Financial Framework. The Green Deal and net-zero ambitions are expected to be a substantial part of it. Eleonora Moro and LĂ©a Pilsner at E3G draw attention to Research & Innovation (R&I, or R&D), often in danger of being seen as a luxury in times of crisis because the big wins are not immediate. Already, the EU could do much better. Looking at … [Read more...]
Wireless recharging of EVs as they drive?
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars. Stationary wireless EV charging has already been piloted and promoted by companies like Connected Kerb in the UK and car manufacturers. Experiments with the mobile version have also been conducted. Clearly, the less often an EV has to stop to recharge the better. But this has run into the problems of energy conversion … [Read more...]
Recyclable Wind Turbine Blades: thermoplastic, next-generation
When wind turbine blades are decommissioned they are usually scrapped and thrown into landfill because they cannot be recycled. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades. As wind installations increase so will that number. It's because most blades are constructed from epoxy or other thermoset resins. So National Renewable Energy Laboratory (NREL) researchers are using a thermoplastic resin, … [Read more...]
Floating Offshore Wind Turbines: utility scale by 2024?
Floating wind turbines can access deeper waters that the usual fixed offshore ones. There the wind speeds are greater and more consistent. It opens the door to even greater efficiency and cost reductions. America’s National Renewable Energy Laboratory (NREL) has summarised a webinar by their Offshore Wind Research Platform Lead, Walt Musial. Other main take-aways include: floating platforms have long been engineered and proven by the oil and gas … [Read more...]
