Delaware Ph.D. student hopes to solve energy woes with renewable hydrogen production
Hydrogen fuel is a fickle mistress. On one hand, it teases us with the promise of renewable energy and a cleaner tomorrow. On the other hand, it's most often produced with natural gas as the source -- hardly the clean break from fossil fuels that many had envisioned. Fortunately, there are other methods to harness this abundant element, and a doctoral student at the University of Delaware may have created a worthwhile process. Similar to previous research we've seen -- which relies on ceric oxide and energy from the sun -- Eric Koepf has designed a reactor that combines zinc oxide powder, solar rays and water to derive hydrogen as a storable energy source. Most intriguing, it's thought that the zinc oxide byproduct from the reaction will be reusable -- a potential gateway to sustainable energy. Koepf will spend the next six weeks in Zurich at the Swiss Federal Institute of Technology, where his reactor prototype will be put through its paces to determine its efficiency and effectiveness. If successful, his advisors envision that one day, we may see giant versions of Koepf's reactors producing hydrogen on an industrial scale. We certainly won't fault them for dreaming big.
New solar machine could generate hydrogen fuel, food for your future vehicle
We're hesitant to file this one in the folder marked "Awesome Things That'll Never Happen," but it's definitely on the watch list. A new prototype solar device has been concocted to convert sunlight into fuel, much in the same way a plant does. Eco-minded folks will probably understand that conventional photovoltaic panels "must use the electricity they generate in situ," and thus, cannot deliver energy at night; this here device takes a rather unorthodox approach, using the sun's rays along with ceria (a magical, marvelous metal oxide) to "break down carbon dioxide or water into fuels which can be stored and transported." In theory, at least, the device could be used to create hydrogen and / or carbon monoxide, with the former being obviously useful for fueling up hydrogen-based cars of the future. Sadly, the existing prototype is horribly inefficient -- only around 0.7 percent of the solar energy can be converted into fuel -- but researchers are adamant that they can boost that to nearly 20 percent in time. We'll check back in a decade or so to see how things are progressing.
