    Recently the Prime Minister of India announced the launch of the National Hydrogen Mission on India’s 75th Independence Day.

    About Mission National Hydrogen Mission

    • It was proposed in the Union Budget 2021.
    • The government’s aim is to make India a global hub for the production and export of green hydrogen.
    • Green hydrogen energy is vital for India to meet its Nationally Determined Contributions.
      • It is a clean-burning molecule, which can decarbonise a range of sectors including iron and steel, chemicals, and transportation.
    • The initiative has the potential of transforming transportation.

    Major Activities to be carried out under the Mission

    • Creating volumes and infrastructure
    • Demonstrations in niche applications 
    • Goal-oriented Research & Development
    • Facilitative policy support
    • A robust framework for standards and regulations for hydrogen technologies

    Need and Significance of the Mission

    • Clean and More Efficient
      • Hydrogen is the lightest element and produces water on combustion.
      • It is about 2-3 times more efficient than burning petrol.
    • Transportation Sector Transformation
      • The transportation sector is one of the most polluting industries.
        • It contributes nearly 1/3rd of all greenhouse gas emissions.
      • Hydrogen fuel cell cars have a near-zero carbon footprint.
        • Thus, it can help India in achieving its emission goals under the Paris Agreement
      • Hydrogen Fuel cells are better than Battery electric vehicles.
        • They enable a refuelling time of just 5 minutes, compared to 30-45 minutes of charging for a Battery operated Electric Vehicle.
      • Also, cars get better energy storage per unit volume and weight, freeing up a lot of space for other things.
      • It is also effective for sectors that cannot be electrified like shipping and air travel.
    • Storage option for Solar and Wind Energy
      • Renewable energy that cannot be stored or used by the grid can be channelled to produce hydrogen.
    • Encountering Chinese Hegemony in Rare Earth Mineral
      • Hydrogen Fuel has the potential to reduce India’s demand for rare earth minerals used in the manufacturing of batteries for electric vehicles.
    • Energy from Waste
      • Bio and plastic waste can be converted into hydrogen. 
        • It will help to combat twin problems of waste management and energy security.
    • Reducing India’s Current Account Deficit (CAD) 
      • India imports 85% of its oil and 53% of its gas demand. 
      • Green hydrogen has the potential to reduce import dependency on fossil fuels.
    • Addressing uncertainty in global energy markets 
      • Due to instability in the Gulf Region, there is often a  spike in crude oil prices impacting Indian Energy security.

     

    About Hydrogen

    • 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, odourless, tasteless, colourless, and highly combustible diatomic gas.

     

    What is Hydrogen Fuel?

    • 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.
    • It can be manufactured by 
      • Electrolysis of water by using direct current.
      • Natural Gas Reforming/Gasification: 
        • Natural Gas on reaction with steam produces Synthesis gas.
        • Synthetic gas is a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide.
      • Fermentation: Biomass is converted into sugar-rich feedstocks that can be fermented to produce hydrogen.
    • It is then stored after mixing or converting to ammonia or synthetic gas for easy liquefaction and transport.

    Types of Hydrogen Fuel

    • Grey Hydrogen: 
      • Manufactured using Natural Gas without carbon sequestration
    • Brown Hydrogen: 
      • Manufactured using Coal without carbon sequestration.
    • Blue Hydrogen: 
      • Manufactured using Natural Gas with carbon sequestration.
    • Green Hydrogen: 
      • Manufactured using Renewable Energy.

    Instances of Usage 

    • Globally
      • Hydrogen’s potential as a clean fuel source has a history spanning nearly 150 years.
        • In 1937, the German passenger airship LZ129 Hindenburg used hydrogen fuel to fly across the Atlantic.
        • In the late 1960s, hydrogen fuel cells helped power NASA’s Apollo missions to the moon.
        • South Korea and Japan are focused on moving their automotive markets to hydrogen, and the potential of the fuel cell.
          • In 2017, Japan formulated the Basic Hydrogen Strategy.
          • It sets out the country’s action plan by 2030, including the establishment of an international supply chain.
          • South Korea launched its Hydrogen Economy Development and Safe Management of Hydrogen Act, 2020.
    • Indian Scenario-
      • Delhi is the first Indian city to operate buses running on hydrogen spiked compressed natural gas (H-CNG).
    • H-CNG is 18% hydrogen in CNG, produced directly from natural gas, without resorting to conventional blending. 
    • NTPC Ltd is operating a pilot to run 10 hydrogen fuel cell-based electric buses and fuel cell electric cars in Leh and Delhi. 
      • It is also considering setting up a green hydrogen production facility in Andhra Pradesh. 
    • The Ministry of Road Transport and Highways (MoRTH) issued a notification proposing amendments to the Central Motor Vehicles Rules, 1989.
      • It includes safety evaluation standards for hydrogen fuel cell-based vehicles.
      • It will act as a supporting regulatory framework.

    Challenges in harnessing Hydrogen Economy

    • Infrastructural Issues : 
      • A big barrier to the adoption of hydrogen fuel cell vehicles has been a lack of fuelling station infrastructure.
      • There are fewer than 500 operational hydrogen stations in the world today, mostly in Europe, followed by Japan and South Korea.
    • Energy-intensive process of Hydrogen generation
      • The energy needed to produce green hydrogen is relatively higher.
      • As the technology is in a naive state and the energy requirement for splitting water or Methane is high, it is costly at present.
    • High R&D requirement
      • The newer technology demands higher research input for making the process cheap and scalable.
    • Multiple regulatory authorities: 
      • Red tapism happens due to the involvement of multiple ministries and the lack of coordination between them.
    • Transportation of hydrogen: 
    • Hydrogen in gaseous form is highly inflammable and difficult to transport. Safety is seen as a concern
    • Difficulty in Detection  :
    • Hydrogen lacks smell, which makes any leak detection almost impossible thus increasing the potential dangers.

    Way Forward

    • There is a need to reduce electrolyser costs and supply chain logistics.
      • This will require funding.
    • Policymakers should also consider how to create legislative frameworks that facilitate the integration of the hydrogen-based sector.
    • Public investments need to be strategized and channelised well.
