LIVERMORE, Calif. A study by researchers at Sandia National Laboratories concludes that a number of existing gas stations in California can safely store and dispense hydrogen, suggesting a broader network of hydrogen fueling stations may be within reach.
The report examined 70 commercial gasoline stations in the state of California and sought to determine which, if any, could integrate hydrogen fuel, based on the National Fire Protection Association (NFPA) hydrogen technologies code published in 2011.
The study determined that 14 of the 70 gas stations involved in the study could readily accept hydrogen fuel and that 17 more possibly could accept hydrogen with property expansions. Under previous NFPA code requirements from 2005, none of the existing gasoline stations could readily accept hydrogen.
The current code, known as NFPA 2, provides fundamental safeguards for the generation, installation, storage, piping, use and handling of hydrogen in compressed gas or cryogenic (low temperature) liquid form.
This work is aligned with Hydrogen Fueling Infrastructure Research and Station Technology (H2FIRST), a new project established by the Department of Energy's Office of Energy Efficiency and Renewable Energy.
Science, risk-informed analysis can accelerate H2 station deployment
The development of meaningful, science-based fire codes and determinations such as those found in the report will help accelerate the deployment of hydrogen systems, said Daniel Dedrick, hydrogen program manager at Sandia. "This work shows that we can reduce uncertainty and avoid overly conservative restrictions to commercial hydrogen fuel installations by focusing on scientific, risk-informed approaches.
"It turns out that the number of fueling stations able to carry hydrogen can
