Fuel cell and Hydrogen - AC fuel cell coming to age of acceptance ? In the late 1990's and up to 2003 I worked with fuel cell plates for GM using Titanium plates within them but industry was looking for a cheaper material than Titanium and the processes needed to manufacture them - units we made parts for were about the size of a small overnight suitcase and developed around 200 HP Seems these units now being marketed for heavy truck use have went well beyond this - also nice to see in note the product is made in the US even though other areas of the world are the final destination. ------------- Faith isn't a jump in the dark.

OK, I'll bite, just WHERE do they get the hydrogen for these hydrogen fuel cells ? ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

n the early stages, [we're focusing on vehicles] that operate on a back-to-base model. So this can be urban transit buses that run a lot of hours a day and come back to a depot, concrete trucks that go out of a plant and come back in to a depot, cold chain logistics delivery type trucks that go out a refrigerated warehouse and do all their deliveries around a city and come back, refuse trucks that go out of a depot and come back. The use case for hydrogen in these kind of scenarios is really very compelling, because you're not dependent on the wider build-out of a hydrogen network to create viability at the fleet level. You just need one piece of hydrogen infrastructure. ------------- Like them all, but love the "B"s. |

95% of ALL commercially available Hydrogen comes from Are ya Ready? Patience Here it Comes!!! Natural Gas!!! |

By Product in H2O in conversion as water vapor Already being used in ice land and they have a fuel station arrangement Methods of hydrogen production Main technologies for hydrogen production include natural gas steam reforming, partial oxidation and auto- thermal reforming of hydrocarbons or renewable fuels (e.g. bioethanol) as well as coal and biomass gasification, water electrolysis, thermo-chemical water splitting, and biological production processes. ------------- Faith isn't a jump in the dark.

How is hydrogen produced?To produce hydrogen, it must be separated from the other elements in the molecules where it occurs. There are many different sources of hydrogen and ways for producing it for use as a fuel. The two most common methods for producing hydrogen are steam-methane reforming and electrolysis (splitting water with electricity. Researchers are exploring other methods. Hydrogen production processes Source: U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, https://energy.gov/eere/fuelcells/hydrogen-production" rel="nofollow - Hydrogen Production (public domain) https://www.eia.gov/energyexplained/hydrogen/images/hydrogen_production_eere.png" rel="nofollow - Steam-methane reforming is a widely used method of commercial hydrogen production Steam-methane reforming accounts for nearly all commercially produced hydrogen in the United States. Commercial hydrogen producers and petroleum refineries use steam-methane reforming to separate hydrogen atoms from carbon atoms in methane (CH4). In steam-methane reforming, high-temperature steam (1,300°F to 1,800°F) under 3–25 bar pressure (1 bar = 14.5 pounds per square inch) reacts with methane in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. https://www.eia.gov/energyexplained/natural-gas" rel="nofollow - Natural gas is the main methane source for hydrogen production by industrial facilities and https://www.eia.gov/dnav/pet/pet_pnp_feedng_k_a.htm" rel="nofollow - petroleum refineries . https://www.eia.gov/energyexplained/biomass/landfill-gas-and-biogas.php" rel="nofollow - Landfill gas/biogas , which may be called biomethane, is a source of hydrogen for several fuel cell power plants in the United States. Biofuels and petroleum fuels are also potential methane sources. Electrolysis is a process that splits hydrogen from water using an electric current. Electrolysis is commonly used to demonstrate chemical reactions and hydrogen production in high school science classes. On a large, commercial scale, the process may be referred to as power-to-gas, where power is electricity and hydrogen is gas. Electrolysis itself does not produce any byproducts or emissions other than hydrogen and oxygen. The electricity for electrolysis can come from renewable sources such as hydro, solar, or wind energy. If the electricity for electrolysis is produced from fossil fuel (coal, natural gas, and petroleum) or biomass combustion, then the related environmental effects and carbon dioxide emissions are indirectly associated with electrolysis. Research is underway to develop other ways to produce hydrogen, such as Hydrogen producers, marketers, government agencies, and other organizations might categorize or define hydrogen according to the energy sources for its production. For example, hydrogen produced using renewable energy might be referred to as renewable hydrogen or green hydrogen. Hydrogen produced from coal may be called brown hydrogen, and hydrogen produced from natural gas or petroleum might be referred to as grey hydrogen. Brown or grey hydrogen production combined with carbon capture and storage/sequestration might be referred to as blue hydrogen. Last updated: January 7, 2021
