Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater from San Francisco Bay. Read the full article.
Researchers at Swansea University figured out a way to convert any kind of plastic waste into hydrogen fuel. The process involves adding a light absorbing material to the plastic and leaving it in a solution exposed to sunlight. The advantages to this process is it’s cheaper than recycling, helps to clean up billions of tons of waste, and can also be used to degrade all sorts of waste not just plastics. The hydrogen gas that’s produced from this process can be used to fuel cars, trains, and planes. Read more about it here.
