Summary of "Hydrogen for Net-Zero"

Core Content

This report, published by the Hydrogen Council in November 2021, outlines the critical role of hydrogen in achieving global net-zero emissions by 2050. It emphasizes that hydrogen is a cost-competitive and scalable energy vector, particularly in sectors that are difficult to decarbonize such as steel, maritime, aviation, and ammonia production. The report also highlights the importance of hydrogen in enabling the integration of renewable energy into the grid, providing energy storage, and facilitating the transport of clean energy over long distances.

Main Points

• Hydrogen's Role in Decarbonization
  Hydrogen can abate 80 gigatons (GT) of CO₂ emissions by 2050, contributing 20% of the total abatement needed in that year.
  In 2050, 660 million metric tons (MT) of renewable and low-carbon hydrogen will be required, which is equivalent to 22% of global final energy demand.
  Annual abatement potential in 2050 is estimated at 7 GT of CO₂, which is equivalent to the combined emissions of the UK, France, and Belgium in 2019.

• Scaling Through 2030
  The report estimates that 75 MT of clean hydrogen must be deployed by 2030 to unlock its full potential.
  This would replace 25 MT of grey hydrogen in ammonia, methanol, and refining; 50 billion liters of diesel in ground mobility; and 60 MT of coal in steel production.
  Early growth will focus on Europe, Japan, and Korea, which are expected to account for 30% of new clean hydrogen demand.
  China and North America will follow with about 20% of the demand each.

• Investment Requirements
  The total capital gap for hydrogen deployment until 2030 is USD 540 billion.
  By 2030, the report estimates that USD 700 billion will be needed, which is about a third of the investments made in renewable energy from 2010 to 2019.
  This includes USD 300 billion for hydrogen production, USD 200 billion for infrastructure, and USD 200 billion for end-uses.

• Regulatory and Policy Framework
  A supportive regulatory framework is essential to unlock the momentum and turn hydrogen projects into actual investments.
  This includes carbon pricing, mandates, and de-risking of large initial investments.
  The report stresses the importance of government and industry collaboration to ensure the right policies are in place.

Key Information

• Global Hydrogen Demand by 2050

  • Mobility: 285 MT of hydrogen demand, contributing to 13 GT of CO₂ abatement.
  • Industrial Uses: 105 MT of hydrogen demand, focusing on feedstock and heating.
  • Steel: 35 MT of hydrogen demand, leading to 12 GT of emissions avoided.
  • Power: 65 MT of hydrogen demand, used for grid balancing and seasonal storage.
  • Aromatics: Early stage development with potential for decarbonization.

• Hydrogen's Systemic Role
  Hydrogen can connect and reshape power, gas, chemicals, and fuel markets.
  It enables energy storage, resiliency, and long-distance energy transmission.
  Hydrogen-based fuels like ammonia, methanol, and e-methane are promising for maritime and aviation decarbonization.

• Current Momentum and Challenges
  In 2021, over 520 hydrogen projects were announced, up 100% from 2020.
  However, only 13% of these projects have passed the final investment decision (FID), and 40% are in the feasibility or front-end engineering and design (FEED) stage.
  A significant investment gap remains, requiring a five-fold increase in hydrogen project announcements to meet the full abatement potential.

• Call to Action
  The report urges regulators and the industry to act quickly to stimulate demand, enable access through infrastructure, and create scale to reduce costs.
  It emphasizes that the necessary investments are within the order of magnitude of current financial flows into the energy sector.

Conclusion

Hydrogen is a key player in the global transition to net-zero emissions by 2050. It is essential for decarbonizing hard-to-abate sectors and enabling the integration of renewable energy. The report calls for accelerated investment and supportive policies to realize hydrogen's potential as a cost-effective and versatile decarbonization vector.
