20150710-5061 BSN HYDROGEN BUSES In the Hawaii Center for Advanced Transportation Technologies garage in Kakaako, shuttle buses are being converted to be used with hydrogen. Stanley Osserman (Dir. at HCATT) stands next to the shuttle bus. The hood is lifted up to show the fuel cell that has replaced the traditional gas engine in the shuttle bus. Hydrogen and air are mixed together with platinum acting as a catalyst that produce electricity to power the shuttle bus. There is no carbon emissions (as with traditional gas engines) as water vapor is the waste product. The shuttle buses will eventually be used at Volcanoes National Park. The bus also has a lithium battery to store some energy. The project involves the National Park Service, Dept. of Energy, UH’s Hawaii Natural Energy Institute and HCATT. They are just waiting for the hydrogen fueling station to be built. PHOTO BY DENNIS ODA. JULY 10, 2015.

20150710-5054 BSN HYDROGEN BUSES In the Hawaii Center for Advanced Transportation Technologies garage in Kakaako, shuttle buses are being converted to be used with hydrogen as the fuel. Stanley Osserman (Dir. at HCATT) shows the fuel cell (he has his hand on it) that has replaced the traditional gas engine in the shuttle bus. Hydrogen and air are mixed together with platinum acting as a catalyst that produce electricity to power the shuttle bus. There is no carbon emissions (as with traditional gas engines) as water vapor is the waste product. The shuttle buses will eventually be used at Vocanoes National Park. The bus also has a lithium battery to store some energy (the battery is directly behind him. It is not installed yet, but will be placed under the fuel cell). The project involves the National Park Service, Dept. of Energy, UH’s Hawaii Natural Energy Institute and HCATT. They are just waiting for the hydrogen fueling station to be built. (Note: the silver contraption on the lower part of the picture is a sulfur scrubber that was installed as it removes the sulfur in the fog that is in the air at Volcanoes National Park. This sulfur scrubber is not normally in the engine compartment) PHOTO BY DENNIS ODA. JULY 10, 2015.
