1. Hydrogen based technologies
Experts from India and Japan discussed possibilities of collaboration for the promotion of hydrogen-based technologies as well as related innovations, trends, concerns, and solutions at a webinar on De-carbonisation: Exploring the Hydrogen Prospects and Innovative Technologies.
(Note: In the above context, a newer concept of Hydrogen Fuel cell is being provided here from the exam point of view by us.)
Prelims GS – Science & Technology
Hydrogen Fuel cell:
- A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water.
- Fuel cells are often compared to batteries.
- Both convert the energy produced by a chemical reaction into usable electric power.
- However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge.
- Fuel cells are a promising technology for use as a source of heat and electricity for buildings and as an electrical power source for electric motors propelling vehicles. Fuel cells operate best on pure hydrogen.

Mains GS3 – Science & Technology
Significance of Hydrogen-based technologies:
- Hydrogen enables high efficiency and zero or near-zero-emissions operations.
- Green hydrogen will be good for industrial processes, the production of chemicals, iron and steel, food and semiconductors, and refineries.
- Hydrogen could be a good alternative because of its capability of producing lower emissions and less pollution.
- The advantage of the hydrogen Energy system is that hydrogen gas is generated using a renewable energy source, instead of fossil fuels, it is stored in a safe way, overcomes challenges such as the intermittency of sunshine, and a clean, alternative power source.
