Thermal Processes For the Production Of Hydrogen


Thermal processes:
Natural Gas Reforming
Steam Methane Reforming
Hydrogen is produced from methane in natural gas using high-temperature steam
Methane reacts with the steam in presence of a catalyst to produce hydrogen
This process accounts for about 95% of the hydrogen used today in the U.S.
Partial oxidation
Produces hydrogen by burning methane in air
Gasification
Process in which coal or biomass is converted into gaseous components by applying heat under pressure and in the presence of steam
A subsequent series of chemical reactions produces a synthesis gas which reacts with steam to produce more hydrogen that can be separated
Renewable Liquid Reforming
Biomass is processed to make renewable liquid fuels, such as ethanol or bio-oil, that are then reacted with high-temperature steam to produce hydrogen
This process is very similar to reforming natural gas

Process Of Hydrogen Production


There are three general categories of Hydrogen production
Thermal Processes
Electrolyte Processes
Photolytic Processes

i will explain these processes in later posts

Production Of Hydrogen


Production
The biggest challenge regarding hydrogen production is the cost
Reducing the cost of hydrogen production so as to compete in the transportation sector with conventional fuels on a per-mile basis is a significant hurdle to Fuel Cell's success in the commercial marketplace

Hydrogen Efficiency




Major advantage of a hydrogen fuel cell is its efficiency. An internal combustion engine uses less than 20 percent of the chemical energy in gasoline, making it a relatively inefficient process. A fuel cell, by contrast, is considerably more efficient, utilizing roughly 60 percent of the energy available in hydrogen.



Conversion Of Energy

 The processes which convert energy into useful forms have limited thermodynamic efficiencies, typically only 10-40%. This means that typically 60-90% of the input energy becomes waste energy. Often significant waste materials are also produced.
