MaHyTec is producing a hydrogen-powered riding lawn mower for market. The mower is a bi-cylinder 500ccm engine unit which burns hydrogen (no fuel cells), which keeps the price lower than it would otherwise be. H2 storage is at low pressure (about 3 bar) to give the mower between 3 and 4 hours of operation per [...]

December 5th, 2011 Aaron Turpen from GreenCarCongress Researchers at the University of Oregon (UO) have developed a boron-nitrogen-based liquid-phase storage material for hydrogen that works safely at room temperature; is both air- and moisture-stable; releases H2controllably and cleanly at temperatures below or at the proton exchange membrane fuel cell waste-heat temperature of 80 °C; utilizes catalysts that are cheap and abundant [...]
Nissan’s New Fuel Cell Much Cheaper
October 16th, 2011 Aaron Turpen Nissan Motor Co has announced that their latest fuel cell stack for testing in hydrogen fuel cell vehicles is 1/6th the cost of its 2005 predecessor and provides double the power density. This incredible step forward is thanks to better structuring of the cells to cut its size in half and reducing the use of [...]
