Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]
Direct capture of CO2 from seawater: new research cuts costs, ready for pilot in 2025
Direct capture of CO2 from the air is already established in pilot phase in sites around the world, but costs are very high. So it is puzzling that capturing CO2 direct from the sea is yet to be tested properly. After all, the concentration of CO2 in seawater is more than 100 times greater than in the air, pointing at a process that should be much more efficient. David Chandler at MIT looks at research there that has uncovered cheaper and more … [Read more...]
New thermoplastic blades for coastal Tidal Energy turbines
Large-scale tidal power turbines provide an option for clean energy generation that doesn’t depend on the weather, like wind and solar. Research led by NREL is using, for the first time anywhere, thermoplastic composite blades that will improve fatigue performance over typical epoxy blades, can be manufactured faster and more energy-efficiently, and can be recycled. The test site is located in New York City's East River, installed in Verdant … [Read more...]
