This report is developed as a part of the project “EMSA study investigating the safety of hydrogen as fuel on ships”. The overall objective of the project is to carry out a structured set of safety assessments and reliability analyses,delivering a Guidance document addressing ships using hydrogen as fuel. The purpose is to assist the industry and the regulators towards a safe and harmonised deployment of this relevant technology that could demonstrate an important step towards decarbonisation of the sector.

On March 11, 2024, the U.S. Environmental Protection Agency (EPA) published the much-anticipated Safer Communities by Chemical Accident Prevention Rule (SCCAP) Final Rule, an update to EPA’s Risk Management Program (RMP) 40 CFR Part 68, under the Clean Air Act Amendments of 1990 (CAA). This is the first substantial change to the rule since its inception in 1996.

The adoption of hydrogen (H²) as a clean, zero-carbon renewable energy source promises a global revolution, eliminating harmful emissions responsible for climate change. This white paper explores the opportunities and implications of an emerging hydrogen society. MSA Safety examines workplace safety risks and challenges posed when producing, handling, transporting, and storing alongside suggested best practices, safety measures, and detection technologies.

Natural gas was first used as a vehicle fuel as far back as the 1930s. The first natural gas vehicles, which ran on uncompressed natural gas, were called “gas bag” vehicles and were used to combat gasoline shortages during World War I [1]. During and after World War II, compressed natural gas (CNG) vehicles using fuel tanks mounted on the roof gained popularity in France and Italy [2]. Today, there are more than 24 million CNG vehicles in service worldwide, including CNG buses that continue the early tradition of mounting fuel tanks on the roof.  

The HSP has reviewed many safety plans for gaseous hydrogen. An emerging trend is the use of liquid (cryogenic) hydrogen in the commercial market, potentially near residential areas, for fueling hydrogen fuel cell vehicles. Finding a “qualified” person to determine liquid hydrogen code compliance is difficult, and the skills necessary of such an individual are not well defined in the codes and standards.
