What is Hydrogen fuel?

• Hydrogen is the lightest and first element on the periodic table. Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2.
• At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas.
• Hydrogen fuel is a zero-emission fuel burned with oxygen. It can be used in fuel cells or internal combustion engines. It is also used as a fuel for spacecraft propulsion.

Occurrence of Hydrogen:

• It is the most abundant element in the universe. The sun and other stars are composed largely of hydrogen.
• Astronomers estimate that 90% of the atoms in the universe are hydrogen atoms. Hydrogen is a component of more compounds than any other element.
• Water is the most abundant compound of hydrogen found on earth.
• Molecular hydrogen is not available on Earth in convenient natural reservoirs. Most hydrogen on Earth is bonded to oxygen in water and to carbon in live or dead and/or fossilized biomass. It can be created by splitting water into hydrogen and oxygen.

Solution: c)

The commerce ministry’s arm Directorate General of Foreign Trade (DGFT) has introduced an online system for traders who seek tariff rate quota (TRQ) for imports, a move aimed at promoting ease of doing business in the country.
The TRQ is a mechanism that allows import of a set quantity of specific products. Tariff quotas are used on a wide range of products but most are in the agriculture sector. Cereals, meat, fruit and vegetables, and dairy products are the most common, and sugar is also protected in most producing countries.
