Hydrogen Sustainable Infrastructure Guidelines (H2SIG)

Summary

The Hydrogen Sustainable Infrastructure Guidelines (H2SIG) provide a framework for evaluating the sustainability of hydrogen infrastructure projects in the United States, leveraging the Envision® sustainability framework. This effort addresses the lack of specific sustainability assessments for H2 projects, engaging 20 organizations and 7 focus groups to prioritize 18 Envision credits most applicable to H2. The guidelines highlight opportunities for significant environmental and economic benefits. For instance, the Southeastern Pennsylvania Transportation Authority plans a $2 billion to $2.4 billion investment to replace its 1,400-bus fleet with a 4:1 FCEB to BEB mix by 2040, aiming for up to 95% reduction in GHG and air pollutant emissions, and a 66% reduction in operational energy consumption from 1,767 TJ/Year to 737 TJ/Year. Case studies like SunLine Transit's $18.8 million investment in 5 FCEBs and a 900 kg H2/day PEM electrolyzer, and the Port of Long Beach's tri-generation system producing 2.35 MW of electricity, 1,270 kg H2/day, and 5,300 liters of water/day from biogas, demonstrate practical applications and high potential for Envision scores. Global electrolyzer capacity has already grown by ~475% since 2019, with a projected 10% CAGR until 2030, underscoring the urgent need for such sustainability guidelines.
