Hydrogen Benefits and Considerations. Hydrogen can be produced from diverse domestic resources with the potential for near-zero greenhouse gas emissions. Once produced, hydrogen generates electrical power in a fuel cell, emitting only water vapor and warm air. It holds promise for growth in both the stationary and transportation energy sectors.
Electrolysis is a process that splits hydrogen from water using an electric current. Electrolysis is commonly used in high school science classes to demonstrate chemical reactions and hydrogen production. On a large, commercial scale, the process may be referred to as power-to-gas, where power is electricity and hydrogen is gas.
hydrogen-powered electricity turbines that can generate electricity at times of peak demand to help firm the electricity grid as a substitute for natural gas for cooking and heating in homes.
They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a polymer electrolyte membrane fuel cell, a catalyst
Hydrogen can be produced from diverse, domestic resources. Currently, most hydrogen is produced from fossil fuels, specifically natural gas. Electricity—from the grid or from renewable sources such as wind, solar, geothermal, or biomass—is also currently used to produce hydrogen. In the longer term, solar energy and biomass can be used more
As hydrogen is believed to be a combustible gas with rather high energy density, power-to-hydrogen applications are gaining momentum. The hydrogen produced by an electrolyser can then be methanated into methane and injected to the natural gas grid, or stored, providing a balancing service to the energy market.

hydrogen has only one proton and one electron. Hydrogen gas is a diatomic molecule—each molecule has two atoms of hydrogen (which is why pure hydrogen is commonly expressed as "H. 2 "). At standard temperature and pres sure, hydrogen exists as a gas. It is colorless, odorless, tasteless, and lighter than air. Like electricity,
Hydrogen fuel cells (HFCs) convert the hydrogen into electricity to power passenger vehicles, trucks and buses. Larger HFCs can deliver back-up power to a whole building, replacing diesel generators.
