Viability of a Hydrogen Fuel Based Economy
Some “alternates within alternates” are studied and possible improvement of our energy policies are explored. The viability of a hydrogen fuel economy is reviewed. Methanol, ethanol or ammonia versus hydrogen is one area of interest. Others include liquid hydrogen versus jet fuels, the use of geothermal, solar, wind or water energy for production of hydrogen gas versus development of deep earth...
متن کاملElectrocatalysis for the Hydrogen Economy
This chapter deals with the concept of “hydrogen economy”, which was introduced by John O.M’ Bockris in 1972. We summarize the fundamental principles and the progress for the reactions relevant to the hydrogen economy, namely the hydrogen and oxygen evolution for water electrolyzers, and the hydrogen oxidation and oxygen reduction for fuel cells. The activity of each reaction can be correlated ...
متن کاملHydrogen Economy - An Opportunity for Chemical Engineers?
Fossil fuels have provided a convenient and plentiful energy source, and have been used profitably in all sectors of the global economy. However, continued reliance on fossil resources must take note of, and may even be placed in jeopardy by several factors. First, worldwide oil demand continues to increase, and replacing the produced oil is technically and politically demanding and very capita...
متن کاملEngineering Challenges of the Hydrogen Economy
HE TERM “HYDROGEN ECONOMY” is the title of a recent book [Rifkin, 2002], but the concept of using hydrogen as fuel for transportation systems has been advocated by environmentalists and others for at least three decades. There is no universally accepted definition of the “hydrogen economy,” but it is generally viewed as the replacement of the vast majority of petroleum fuels used by transportat...
متن کاملIntegrating Hydrogen into the Uk Energy Economy
Hydrogen is likely to become a major new fuel for transport and district or domestic-scale combined heat and power systems in the 21st century. Depending on the specific production technology, hydrogen can displace fossil fuels and limit or completely displace the production of carbon dioxide. It may also enhance energy system security through increased storage capacity and reduction in the nee...
