Producing hydrogen fuel

Hydrogen gas can be produced using a wide variety of methods and raw materials making is probably the most flexible fuel on the earth. In a traditional plant setting, producing hydrogen gas can begin with raw materials such as coal, water, natural gas, algae or biomass (natural organic composting materials).

Gasification is the technique used for producing hydrogen gas from coal, biomass, or other solid material. It involves subjecting the material or feedstock to extreme heat, cooling it, separating the hydrogen gas, and purifying it for the use in hydrogen fuel car. Hydrogen gas as a fuel for electricity generation will produce much less pollution that regular coal-fired power stations.

Producing hydrogen gas using water is one of the greenest production procedures so far and can be done by several methods. Using electrical current, water can be separated into its component parts of hydrogen and oxygen. The power required can easily come from renewable, natural sources as the sun, wind and water. Nuclear energy or even the earth’s own geothermal energy may also be used.

In Thermochemical Water Splitting, water is heated at high temperatures with certain chemicals to create a chemical reaction that separates the hydrogen from the water. This process is usually found at nuclear power plants. The High Temperature Electrolysis process used for producing hydrogen gas is the same as electrolysis fueled by electricity except that this method utilizes heat generated by nuclear power generation directly.

Producing hydrogen gas using natural gas as the raw material is achieved through a process called Steam Methane Reformation. This is a two-step method, which burns the natural gas to create steam, which results in a synthesis gas from which the hydrogen can be separated. This method, though not as environmentally friendly as electrolysis is currently used to produce roughly ninety-five percent of all hydrogen in the United States.

By employing Photo-Biological Production, hydrogen can be obtained from algae or bacteria recovered from wastewater. When deprived of sulfur, algae produce hydrogen instead of oxygen. The greenest of all possible methods, this method’s feedstock is created from waste by-products and renewable wastes, and is heralded by environmentalists.

When compared to fossil fuel production, producing hydrogen gas clearly provides numerous benefits. No matter the exact production method used, plentiful sources of hydrogen make it clearly the fuel of the future.
