Green Hydrogen in Developing Countries Summary

Core Content

This report, prepared by the Energy Sector Management Assistance Program (ESMAP) of the World Bank, explores the potential of green hydrogen in developing countries as a sustainable energy solution. It outlines the opportunities, challenges, and future directions for integrating green hydrogen into energy systems, mobility, and industrial applications.

Main Points

Why Green Hydrogen?

• Green hydrogen is produced from 100% renewable energy sources and is a zero-carbon energy carrier.
• It offers a versatile solution for decarbonizing hard-to-abate sectors such as heavy industry, buildings, and transport.
• Green hydrogen can support sustainable development goals by improving energy security, reducing dependence on fossil fuels, and creating economic opportunities.

Why Now?

• The global commitment to climate change mitigation has intensified, leading to stronger policy support and investment in low-emission technologies.
• Renewable energy costs have decreased significantly, making green hydrogen more competitive with fossil fuel-derived hydrogen.
• Advances in electrolyzer and fuel cell technologies have improved efficiency, durability, and cost-effectiveness.
• The global shift toward electric mobility is opening new markets for hydrogen-based solutions, especially in long-range, zero-emission applications.

Why Developing Countries?

• Developing countries often have abundant renewable energy resources, which can be harnessed for local green hydrogen production.
• Green hydrogen can help address energy access and reliability in remote and off-grid areas.
• It supports the development of integrated energy systems and can be used in multiple sectors, including industry, transport, and power generation.

Key Opportunities

• Short-term: Fuel cells can provide decentralized power solutions for critical infrastructure and remote areas.
• Medium-term: Green hydrogen can support energy storage and firm power, enabling greater renewable energy integration.
• Long-term: Green hydrogen has the potential to decarbonize heavy industry and transport, especially in sectors where electrification is challenging.

Market Overview

• The global green hydrogen market is still in its early stages, with electrolysis and fuel cell technologies being key enablers.
• As of 2019, the global installed capacity of electrolyzers increased from 32.7 MW (2000–2013) to over 260 MW (2014–2019).
• Major electrolyzer orders include 10 MW (ITM, 2017), 20 MW (Hydrogenics, 2019), and feasibility studies for 250 MW (Netherlands) and 12 GW (Pilbara, Australia).
• The cost of green hydrogen production is expected to decline further with increased manufacturing capacity and automation.

Applications of Green Hydrogen

Energy Applications

• Residential: Fuel cells can provide power for homes and critical infrastructure.
• Back-up power: Used in telecommunications and emergency systems.
• Off-grid power: Enables remote areas to have reliable energy access.
• Commercial: Fuel cells are being used to power commercial buildings and facilities.
• Utility-scale: Can provide large-scale power solutions and support grid stability.

Mobility Applications

• Fuel cell electric vehicles (FCEVs): Increasing in number and becoming more cost-effective.
• Fuel cell electric buses (FCEBs): Deployed in countries like India and China, with declining costs.
• Shipping and trains: Hydrogen can serve as a clean fuel for heavy transport.
• Material handling and forklifts: Used in industrial settings, particularly in mining.

Industrial Applications

• Iron and steel: Green hydrogen can replace fossil fuels in high-temperature processes.
• Ammonia production: A promising area for green hydrogen use, with projects like the world's first wind-to-ammonia project.
• Refining: Hydrogen can be used in refining processes to reduce emissions.
• Glass, food, and other industries: Green hydrogen offers potential for decarbonization in these sectors.

Challenges

• Implementation capacity: Developing countries face a shortage of qualified engineers and technicians to handle hydrogen systems.
• Infrastructure requirements: Building the necessary infrastructure for production, storage, and transport of hydrogen is a significant challenge.
• Safety and risk management: The hydrogen value chain requires specific knowledge and capabilities to ensure safe handling and use.
• Cost: While costs are declining, further reductions are needed for green hydrogen to be competitive at scale.

Areas for Further Research

• Technology development: Continued innovation in electrolyzer and fuel cell performance.
• Policy and regulation: Creating an enabling environment for green hydrogen deployment.
• Economic and financial models: Understanding the cost structures and investment pathways for green hydrogen projects.
• Integration with existing systems: How to best integrate green hydrogen with current energy infrastructure and supply chains.

Conclusion

Green hydrogen has the potential to play a transformative role in the energy transition, especially in developing countries. With the right policies, investment, and technical support, it can provide a reliable, clean, and versatile energy carrier that supports multiple sectors and enhances energy security. The report emphasizes the need for further research and development, as well as the importance of development finance institutions and concessional funds in facilitating the deployment of green hydrogen projects.
