Plug power (plug) which took over General Hydrogen and Cellex are presently using their Forlift Fuel Cells in a large Distribution Center in Ohio. They are having positive results. Deka Battery out of Penn. State is in partnership with Nuvera out of Mass. They are close to mass producing the Fuel Battery for Forklifts in North America. There are a handful of others working the bugs out on this future device that will eventually power the Lift Truck industry. Like any thing else, it will take time to set up the infrastructure for parts, service, training and of course getting hydrogen to the lift trucks. Currently their are several ways to get hydrogen. Truck it in just like propane, install a massive tank to receive liquid gas and use a cryovac system to create pressurized gas (BOC, Air Products), place a reformer in the facility by using the natural gas to make your own presurize gas and other options that our currently being developed. Go to fuelcellsworks dot com to get tons of info about Fuel Developements. Hope this helped. I have been researching Fuel Cell technology for quite some time and Hydrogen is our #1 element on this earth and we will never run out of it. As for lead, acid, fuels and other materials, you will notice that they keep going up. We are using up these resources faster than we may think and when they are gone, they are gone from this earth. Hydrogen will be the power for every machinery in the future since there may be no alternative. You will also have wind, tide, current, solar and other free sources of power mixed with hydrogen power. Cool stuff.

Hydrogen Fuel Cells are here to stay. Implement and proceed with safety in mind
