Hydrogen Production- Thermal Process Natural Gas Reforming Natural Gas Reforming – Steam Methane Reforming- popular method for producing hydrogen – Efforts are focused on natural gas reforming for transition period only Biomass Gasification Biomass Gasification – Renewable sources such as agricultural crop residues, animal waste, and forest residues are used to produce hydrogen

Hydrogen Production- Thermal Process Continued Coal Gasification Coal Gasification – Coal converted into gasses by applying heat under pressure – Coal is an abundant and cheap resource FutureGen, prototype plant supported by government

Hydrogen Production- Electrolytic Process Hydrogen Hydrogen is harvested via fuel cells. There are a few different types, the most apparent being the PEM (Proton Exchange Membrane/ Polymer Electrolyte membrane) Another Another option is the Direct Methanol Fuel Cell – it has some cons, however…

How It’s Used Hydrogen has many uses – however, there are two distinct types Hydrogen has many uses – however, there are two distinct types Fuel cells can be used in cars and many other applications such as homes Fuel cells can be used in cars and many other applications such as homes Otherwise, a internal combustion engine can be fed in the same way that it is powered by petroleum Otherwise, a internal combustion engine can be fed in the same way that it is powered by petroleum

The Cons of Hydrogen Fuel !!!!!

Hydrogen Fuel – The Dark Side Cannot be harvested directly Cannot be harvested directly Too dependent on fossil fuels Too dependent on fossil fuels Cost issues Cost issues Feedstock (coal) can cause pollution Feedstock (coal) can cause pollution Technology to produce Hydrogen will take too long Technology to produce Hydrogen will take too long

Hydrogen is extremely clean fuel! oThe only byproducts are heat and water when used in a fuel cell! oIt is colorless, odorless, and non- polluting! oPure water vapor comes out of exhaust instead of carbon monoxide! oWhen combusted directly or with hydrocarbon fuels, very few emissions are produced!

Hydrogen can be stored for long periods of time If there is a hydrogen leak, it can be replaced with no harm done to the environment
