Hydrogen Fuel - A Promising Solution for Global Warming
Recently, global warming caused by greenhouse gases has received grave concerns all over the world.
Fossil fuel combustion, which accounts for 80% of anthropogenic emissions of greenhouse gases (mostly carbon dioxide) into the atmosphere, is the biggest cause of global warming by human activities.
Therefore, it is urgent to implement strategies to reduce carbon dioxide emission from conventional energy systems.
Hydrogen has an energy content much higher than that of fossil fuels, thus, it can be both a potential fuel and an ideal energy carrier (storage medium).
This fuel is a very promising candidate to substitute fossil fuels in the future because it is clean and renewable when being produced from renewable energy sources such as wind, solar, wave, geothermal and biomass sources.
Electricity generated by these renewable energy sources can be used to electrolyze abundant water for hydrogen production.
In addition, this futuristic fuel can also be produced by processing biomass products, including all energy crops such as corn and sugar, agricultural wastes, industrial organic wastes, and municipal wastes.
There are two main processes for hydrogen production from biomass, namely, gasification and pyrolysis.
These two processes are very potential because biomass is renewable and abundant.
Hydrogen exhibits its most advantageous characteristics when being used in a fuel cell to produce energy.
Hydrogen fuel cell is an electrochemical device that combines hydrogen with air oxygen in the presence of a catalyst to generate electricity and release only heat and water vapor as final emission products.
Thus, the production and application of this fuel cell type can effectively mitigate and eliminate global warming disaster.
Moreover, a hydrogen fuel cell is two to three times more efficient than a conventional internal combustion engine because the fuel cell does not burn fuel but instead it converts directly chemical energy stored in the fuel into electrical energy.
