Comments Off on New nanomaterial pulls hydrogen from seawater to power fuel cells

Hydrogen can be obtained from seawater to power fuel cells , but the process is typically costly because of the electricity required. Researchers created a nanomaterial that can do the job more efficiently. According to the University of Central Florida (UCF), the advance “could someday lead to a new source of the clean-burning fuel .” UCF assistant professor Yang Yang has been working on solar hydrogen splitting for almost a decade. In the process, a photocatalyst sets off a chemical reaction with energy from light . But the photocatalysts don’t work as well in seawater – they don’t stand up well to salt and seawater’s biomass. Yang’s research team came up with a new catalyst that’s not only good for splitting purified water in a laboratory, but can better endure seawater and even harvest light from a broader spectrum. Related: Scientists develop new way to generate electricity via seawater Yang said, “We can absorb much more solar energy from the light than the conventional material. Eventually, if it is commercialized, it would be good for Florida’s economy. We have a lot of seawater around Florida and a lot of really good sunshine.” He said in many cases it’s better to use the sun’s energy to create a chemical fuel than to generate electricity with solar panels . Hydrogen gas can be transported and stored easily. UCF said it’s relatively cheap and easy to make the catalyst, which is comprised of a hybrid material. The journal Energy & Environmental Science published the research the end of September. Scientists from Pacific Northwest National Laboratory in Washington and Tsinghua University in China collaborated on the study. Yang and his team plan to continue researching how to scale up the catalyst fabrication, and to work on splitting hydrogen from wastewater with the catalyst.

Comments Off on The Puerto Rico nursery still up and running thanks to solar power

Solar power is helping flower grower Hector Santiago get back on his feet in Puerto Rico after Hurricane Maria devastated much of the United States territory’s electricity grid . Six years ago, he sank $300,000 into 244 solar panels , and said everyone told him he was crazy because of the cost. Today, he has power and is rebuilding his nursery. Santiago’s Cali Nurseries , which sells decorative plants and poinsettias to firms like Cosco and Walmart, suffered tremendous losses during the storm. Hurricane Maria damaged plants and greenhouses , ripping off roofs and flattening trees. Santiago told The Washington Post his losses amounted to an estimated $1.5 million. Related: Puerto Rico electricity crisis sparks interest in renewable energy But he’s been able to begin rebuilding his Barranquitas farm with the help of electricity thanks his investment in solar energy. The storm damaged 25 percent of the photovoltaic panels, but there’s still enough energy to start rebuilding his operation. The power allowed him to keep pumping water from wells, as the business’ 19 employees cleaned up and repotted plants. Santiago was unable to get back to his farm for five days following the hurricane, and when he finally returned he found his employees hard at work, as they had been since the first day. He told The Washington Post, “I just started crying, I choked up, when I saw them working like nothing had happened. They give me the strength to not give up and to do whatever I have to do to continue with my business.” The devastation in Puerto Rico has resulted in an increased interest in renewable energy . Solar installation firm owner Henry Pichardo, who works out of Bayamon, said Hurricane Maria could boost his business by 20 percent per year. He said he’s been flooded with inquiries after the storm. He told Reuters, “People are going to become more conscious of how they are living, and invest more in solar.” Via Reuters and The Washington Post Images via Hector Alejandro Santiago Rodriguez on Facebook and Cali Nurseries on Facebook

Comments Off on Breakthrough Producing Hydrogen from Water + Sunlight

Image: Angewandte Chemie, Wiley Sunlight + Water = Hydrogen Gas Scientists at the University of East Anglia, led by Dr. Thomas Nann, report a breakthrough in the production of hydrogen from water using the energy of sunlight. Amidst all the hype about a potential hydrogen economy, which would rely upon the highly energetic and clean burning hydrogen atom, one of the big questions has been whether sufficient hydrog..
