Advancements in the Implementation of Hydrogen Fuel

Amongst global efforts to combat greenhouse gas emissions, hydrogen fuel has emerged as a viable solution in transitioning to a more sustainable and climate-friendly fuel source.

Because of its ability to be produced with zero or near-zero carbon emissions, many regions have begun investing in hydrogen technologies, which has further accelerated industry innovation and job opportunities on a global scale.

Accelerating Hydrogen Fuel Deployment Through H2Hubs

On October 13th, 2023, the U.S. Department of Energy (DOE) announced the allocation of $7 billion dollars to develop seven Regional Clean Hydrogen Hubs (H2 Hubs) strategically located across the U.S. as part of the Bipartisan Infrastructure Law.

The H2Hubs will accelerate the commercial-scale deployment of low-cost hydrogen to meet the nation’s climate and energy security goals.

The H2Hubs are anticipated to generate a combined output of three million metric tons of hydrogen each year, contributing to almost one-third of the 2030 U.S. production goal while reducing emissions from hard-to-decarbonize industrial sectors.

Additionally, the H2Hubs are projected to decrease carbon dioxide emissions by 25 million metric tons annually, as well as generate and maintain tens of thousands of jobs nationwide while promoting healthier communities.

Hydrogen Fuel Provisions in the I-Codes

Model codes and standards must be updated to address safety gaps when hydrogen is blended into the natural gas supply. The Code Council is currently in the process of developing the 2027 International Codes® (I-Codes), which includes code proposals developed by the PMG and Fire Code Action Committees that address the blending of gaseous hydrogen with natural gas in the built environment.

Gaseous hydrogen fuel at least 95 percent by volume and no more than 1 percent oxygen, has had code requirements included in the International Fuel Gas Code® (IFGC®) and many other publications for years. The working group’s scope was to expand the minimum safety provisions to address natural gas including gaseous hydrogen admixtures.

Hydrogen Working Group

The PMGCAC Hydrogen Working Group was composed of representatives from academia, national and international associations, national testing laboratories, manufacturers of appliances/equipment/piping systems, contractors, engineers, natural gas energy suppliers, standard development organizations, building and fire officials and other stakeholders.

This group assessed existing I-Code requirements related to hydrogen use, considering current industry practices and safety needs in the built environment.

Through collaborative efforts, rigorous code proposal development and proactive regional outreach, the Code Council is ensuring codes address the global paradigm shift towards a safer, more sustainable and efficient hydrogen-fueled future.

Center for Hydrogen Safety (CHS) Hydrogen Hubs Working Group
Read details▼

Worldwide, there's a noteworthy surge in activities and substantial funding allocated toward advancing hydrogen hubs.

As these initiatives proceed, there will naturally arise inquiries about safety protocols and optimal practices. In the realm of hydrogen safety, the preeminent global authority is the Center for Hydrogen Safety (CHS). To meet the needs of these developing hubs CHS is establishing a Hydrogen Hubs Working Group that will be open to any CHS member that is a part of a global hub.

The Hydrogen Hubs Working Group will provide a forum for hub participants to:

  • Discuss safety topics and issues
  • Participate in a community to resolve shared problems.
  • Develop resources that can be used among working group members
  • Highlight and promote significant hydrogen safety issues to outside entities
