Green hydrogen is hydrogen gas produced through the process of electrolysis, where water (H₂O) is split into hydrogen (H₂) and oxygen (O₂) using electricity generated from renewable energy sources such as wind, solar, or hydropower.
According to BIS the Global Green Hydrogen Market, was valued at $828.2 million in 2023, and it is expected to grow with a CAGR of 67.19% during the forecast period 2023-2033 to reach $141.29 billion by 2033.
Green Hydrogen Overview
Green Hydrogen refers to Hydrogen produced using renewable energy sources, specifically wind, solar, or hydropower, in a process known as electrolysis. Unlike conventional methods that rely on fossil fuels, such as natural gas or coal, green hydrogen production involves splitting water molecules into hydrogen and oxygen without emitting carbon dioxide (CO2), aligning with sustainability goals.
The electrolysis process, powered by renewable energy, distinguishes green hydrogen as an environment-friendly alternative. This cleaner production method has the potential to significantly impact sectors with high emissions, including transportation, manufacturing, and energy production, contributing to the global transition toward a low-carbon economy.
Green Hydrogen stands out as a versatile and clean energy carrier, offering a sustainable substitute for traditional fossil fuels. Its application extends to addressing the intermittency of renewable energy sources by providing a means of storage and transportation.
Market Drivers Challenges and Opportunities
Green hydrogen, produced using renewable energy sources like wind, solar, or hydropower, holds great promise for reducing carbon emissions and transitioning to a more sustainable energy system.
Drivers Includes
1 Environmental Concerns and Regulations:
- Climate Change Mitigation: The need to reduce greenhouse gas emissions is a significant driver, as green hydrogen produces no carbon emissions when used as a fuel.
- Government Policies and Incentives: Governments worldwide are implementing policies, subsidies, and tax incentives to promote the adoption of green hydrogen.
2 Technological Advancements:
- Electrolysis Technology: Improvements in electrolysis technology, which is used to produce green hydrogen by splitting water into hydrogen and oxygen using renewable electricity, have made the process more efficient and cost-effective.
- Fuel Cell Technology: Advances in fuel cell technology are making hydrogen a more viable option for a variety of applications, from transportation to stationary power generation
Challenges includes
- Cost of Production: Producing green hydrogen is currently more expensive than producing hydrogen from fossil fuels (gray hydrogen) or even blue hydrogen (which includes carbon capture and storage). The high cost is primarily due to the expense of electrolyzers and the electricity required from renewable sources.
- Efficiency: The process of electrolysis, which splits water into hydrogen and oxygen, is not highly efficient, leading to energy losses. Further losses occur during the storage, transportation, and conversion back to electricity or other forms of energy.
- Storage and Transportation: Hydrogen is a low-density gas, making it challenging to store and transport. It requires high-pressure tanks, cryogenic temperatures, or chemical carriers, all of which add to the complexity and cost.
- Renewable Energy Availability: The production of green hydrogen depends on the availability of surplus renewable energy. The intermittency of renewable energy sources like wind and solar can affect the continuous production of green hydrogen.
- Public Acceptance and Awareness: There is limited public awareness and understanding of hydrogen as an energy carrier.
- Safety Concerns: Hydrogen is highly flammable and requires careful handling and safety measures.
