A project to develop a hydrogen fuel cell powered multi-rotor unmanned aerial vehicle (UAV), has beaten its original test flight target of 60 minutes with a 5 kg payload, setting an exciting new benchmark for flight time and payload in the commercial UAV industry.
An accelerating need to find energy sources to substitute decreasing fossil fuels means that hydrogen will probably have a significant role in the future.
Researchers developed a nanostructured composite material, which can be used as a catalyst for electrochemical splitting of water to synthesize hydrogen.
A team of researchers from the Institute of Chemical Technology (ITQ), Valencia’s Polytechnic University (UPV) and the Superior Council of Scientific Investigations (CSIC) have created ceramic membranes which make it possible to form compressed hydrogen from methane in a cleaner, inexpensive way.
HyperSolar, the developer of an innovative technology to create renewable hydrogen using sunlight and any source of water, recently announced it has successfully developed a vital component made of earth-abundant material which will lower the overall cost of its process to produce renewable hydrogen.
It has been known for long in the scientific community that cerium is the best element to employ when splitting water into oxygen and hydrogen — a key method in developing hydrogen gas for fuel. However so far it is not clear as to why cerium is so successful.
Lehigh Researchers are working together with colleagues in China and at three national laboratories in the United States in order to develop a gold-based catalyst that they think could enhance the efficiency and performance of fuel cells that are hydrogen powered.
One recent solution to the traffic congestion that troubles coastal cities is maritime transportation. But with urban passenger ferries running in tourist areas and sensitive environments, hydrogen fuel cell-powered passenger ferries offer a noiseless, zero-emission alternative to conventional diesel vessels.
Christopher J. Kiely, Harold B. Chambers Senior Professor, Materials Science and Engineering at Lehigh University, along with an international team have created a new low-temperature catalyst for making high-purity hydrogen gas while using up carbon monoxide (CO) at the same time.
Although the buildup around hydrogen fuel cells has subsided, researchers continue to hunt for new technologies that could permit such devices to gain a stronger foothold.
