Electrocatalysis 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 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...
متن کاملProspects on Fuel Economy Improvements for Hydrogen Powered Vehicles
Fuel cell vehicles are the subject of extensive research and development because of their potential for high efficiency and low emissions. Because fuel cell vehicles remain expensive and the demand for hydrogen is therefore limited, very few fueling stations are being built. To try to accelerate the development of a hydrogen economy, some original equipment manufacturers (OEM) in the automotive...
متن کاملComparative Study on Hydrogen Economy Policy of China and Korea
In this paper, we compare the hydrogen economy policy of China and Korea. We point out that the two countries have their respective advantages such as strong motivation from necessity, national support by law and diversity in regional policies for China and leading strength from government, academic support by universities and participating energy of enterprises for Korea. Also China and Korea ...
