City's first hydrogen filling station opens at new 'green' University research building
Drivers of hydrogen cars will be able to fill up their tanks in Nottingham for the first time later this week, following the launch of an innovative sustainable energy research facility at The University of Nottingham. Read more
A Teesside-based business at the cutting edge of technology has scored a world first by designing a ground-breaking environmentally-friendly fuel cell to power a lighthouse. The historic South Gare lighthouse at the mouth of the River Tees leads to one of the busiest ports in the UK and was thought too exposed to use a fuel cell. But the Centre for Process Innovation (CPI), based at Wilton on Teesside, has worked with its partners to develop the innovation, which can operate in some of harshest weather conditions. The South Gare site is regularly lashed by high winds and rough seas but the lighthouse, built in 1884, plays a pivotal role in the success of Teesport, one of the UKs three busiest ports. The hydrogen fuel cell has been powering the South Gare light, which can be seen from 25 miles out to sea, for several months.
The prospect for the wide spread use of hydrogen as a portable energy carrier is dependent on finding a clean, renewable method of production. At Penn State University, a research group headed by professor of electrical engineering Craig Grimes in the Materials Research Institute is "only a couple of problems away" from developing an inexpensive and easily scalable technique for water photoelectrolysis - the splitting of water into hydrogen and oxygen using light energy - that could help power the proposed hydrogen economy.
Most current methods of hydrogen production split hydrogen from natural gas in a process that produces climate changing greenhouse gas while consuming a nonrenewable resource. A more environmentally friendly approach would produce hydrogen from water using the renewable energy of sunlight.
In a paper published online in Nano Letters on July 3, 2007, lead author Gopal K. Mor, along with Haripriya E. Prakasam, Oomman K. Varghese, Kathik Shankar, and Grimes, describe the fabrication of thin films made of self-aligned, vertically oriented titanium iron oxide (Ti-Fe-O) nanotube arrays that demonstrate the ability to split water under natural sunlight.
A unique discovery being published today by University of Tennessee Knoxville scientists has led to a $1.2 million grant to help overcome roadblocks facing the wide-scale use of hydrogen as a national energy source. Hanno Weitering, a professor of physics and joint faculty member between UT and Oak Ridge National Laboratory, found that by adding small amounts of the element bismuth to an extremely thin film of lead atoms, he could fine-tune the stability and physical properties of the newly made "quantum alloy." The approach can be also applied to hydrogen fuel cell storage research.
In what looks like an example of modern-day alchemy, scientists at Purdue University in Indiana have come up with a way of turning water in hydrogen using an aluminium alloy. If the process is replicable on a large scale, it could have a massive impact on the market for hydrogen fuel cell-powered cars, which could use the technology as a source of on-board hydrogen generation. The process relies on the use of aluminium pellets, which are mixed into liquid gallium (a metal that liquefies at just over room temperature) to produce a liquid aluminium-gallium. When water is added to the compound, the aluminium reacts with the oxygen to form a gel as well as free-standing hydrogen, which can be collected and used to power a fuel cell.
A group of scientists are going to present their breakthrough in hydrogen storage this Wednesday. In contrast to previous storage mechanisms, this method binds hydrogen to a pellet which is completely safe to handle at room temperature. While bound in this medium no hydrogen loss occurs, enabling hydrogen to be stored cheaply for indefinite periods. When needed, the extraction of hydrogen is relatively simple.
