Summary of "Rising to the Challenge of a Hydrogen Economy"

Core Content

This report provides an overview of the emerging hydrogen economy, highlighting the increasing importance of hydrogen in the global transition to a net-zero future. It draws on DNV's survey of over 1,100 professionals and in-depth interviews with industry leaders to explore the current state, future outlook, and key challenges and enablers of hydrogen development.

Main Points

1. Hydrogen's Growing Role in the Energy Transition

• Hydrogen is becoming a central component of the global energy transition, with many organizations viewing it as essential for achieving net-zero goals.
• The majority of energy professionals (74%) believe the outlook for a hydrogen economy has improved significantly in the past year, and 67% expect this trend to continue.
• Hydrogen is expected to grow rapidly, with its share of revenue and spending increasing from 8% and 9% in 2021 to 44% and 33% by 2025, and further to 73% and 57% by 2030.

2. Hydrogen Production Types

• Green hydrogen: Produced via electrolysis using renewable energy, it is the ideal long-term solution but currently too expensive.
• Blue hydrogen: Derived from fossil fuels with carbon capture and storage (CCS), it can serve as a transitional solution to green hydrogen.
• Grey and brown hydrogen: Traditional methods using natural gas and coal, respectively, are still dominant but emit significant CO₂.

3. Key Drivers of Hydrogen Adoption

• The need to replace carbon-intensive parts of business is the top driver for hydrogen adoption.
• Sustainability and profitability are the two most significant motivators for companies entering the hydrogen market.
• Over 84% of respondents believe hydrogen is critical to a low-carbon energy system.
• 73% think the Paris Agreement targets cannot be achieved without a large-scale hydrogen economy.
• 74% believe hydrogen is essential for achieving a zero-carbon economy by 2050.

4. Challenges and Enablers

• Challenges:

  • Infrastructure development is a major hurdle, with 38% of respondents identifying it as the top risk.
  • Cost reduction remains a key concern, particularly for green hydrogen.
  • Technical barriers in hydrogen adoption, especially in the steel industry, are significant.
  • Safety is a critical issue, with many respondents emphasizing the need for robust safety standards.

• Enablers:

  • Strong, stable, and supportive regulations are the top enabler for a successful hydrogen economy.
  • Carbon pricing is also a powerful enabler, with 80% of respondents stating that effective carbon-pricing regulations are needed before hydrogen can scale.
  • Reuse of existing gas infrastructure is seen as a cost-effective solution, with 78% of respondents supporting it.
  • Standardization and innovation in technology, particularly in electrolyzers and compression systems, are vital for reducing costs and increasing viability.

5. Industry-Specific Applications

• The steel industry is a major potential user of hydrogen, as it seeks to decarbonize its processes.
• Hydrogen can replace fossil fuels in energy and feedstock applications across various sectors, including transport, power generation, and chemical production.
• However, the cost and scalability of hydrogen remain major issues, especially for applications like international shipping, which may require several times the current renewable energy output to be powered.

6. Global and Regional Perspectives

• The report covers 80 countries and highlights the varying levels of investment, policy support, and industry interest.
• Countries like China are expected to play a significant role in accelerating the hydrogen economy due to its large market and energy demands.
• In Europe, there is growing confidence in reusing gas networks for hydrogen, with projects like the EU's Hydrogen Backbone showing potential.

Key Uncertainties

• The hydrogen economy faces several uncertainties, including the pace of infrastructure development, the cost of production, and the effectiveness of regulatory frameworks.
• There is a need for collaboration between governments, industries, and stakeholders to align supply and demand, and to ensure that hydrogen is integrated safely and efficiently into the energy system.

Conclusion

The hydrogen economy is gaining momentum, but its success depends on addressing significant challenges, including infrastructure development, cost reduction, and regulatory support. While green hydrogen is the ideal long-term solution, blue hydrogen may serve as a transitional option. The report underscores the importance of a balanced approach that integrates hydrogen with electrification, rather than viewing them as competing technologies.
