Liquid hydrogen and fuel cell powered UAV sets new endurance record

By Damir Beciri
12 May 2013

ion-tiger-flightResearchers at the U.S. Naval Research Laboratory (NRL) broke the endurance record for small electric Unmanned Aerial Vehicles (UAVs) by developing a vehicle powered by liquid hydrogen fuel and a fuel cell. This flight shatters their previous record of 26 hours and 2 minutes set in 2009 using the same vehicle, but with gaseous hydrogen… »

empa-hydrogen-carYou can often read about hydrogen powered vehicles that could be used in near future, but there was a project active since 2009 that intended to take hydrogen drives out of the laboratory and onto the streets in order to gain experience on using them under practical conditions. The subject of the pilot trial is… »

One Comment11 December 2010

ren-groupThere are many efforts to invent ways to make water desalination a low energy consumption process. Water purification usually requires a lot of energy as well, while utility companies need large amounts of water for energy production. Their goal is to find a low-energy-required treatment technology. Researchers from the University of Colorado Denver College of… »

Artificial photosynthesis system converts water into hydrogen

By Damir Beciri
One Comment20 October 2009

artificial-photosynthesis-3The energy available in sunlight is a resource we’ve only begun to really get a handle on. Current photovoltaic-cell technology, typically a semiconductor-based system, is expensive, not very efficient, and only does instant conversions from sunlight to electricity. But an artificial photosynthesis system or a photo-electrochemical cell that mimics what happens in plants could potentially… »

Biosolar hydrogen production with green algae

By Damir Beciri
1 October 2009

green_algae_chlamydomanas_reinhardtiiA fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. In order to produce energy, fuel cells use oxygen and hydrogen. Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. It’s also the most plentiful known element in the universe. Despite its simplicity and abundance,… »
