(i) The hydrogen economy is the economy where the dominant role of the fuel and energy carrier is performed by hydrogen along with the electricity.
(ii) Hydrogenation is the chemical reaction between molecular hydrogen (H2) and another element or compound.
It is carried out usually in the presence of a catalyst such as platinum, palladium or nickel.
It is used to convert a liquid oil into a solid fat.
(iii) Syngas gas is also known as Water gas.
It is a mixture of hydrogen (H2) and carbon monoxide (CO) that is used as a fuel gas.
Syngas is produced from a wide range of carbon containing feedstocks.
Syngas is used in the production of a wide range of chemicals.
(iv) The water gas shift reaction (WGSR) is a comparatively heat releasing reaction between steam and carbon monoxide (CO) to form hydrogen (H2) and carbon dioxide(CO2).
(v) Electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent (Hydrogen, Oxygen) into electricity through a pair of redox reactions is known as a fuel cell.
First fuel cell was invented by Sir William Grove in 1838.
