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.

Summary report of the Clean Hydrogen Joint Undertaking Expert Workshop on the Environmental Impacts of Hydrogen

This report provides an evaluation by members of the Hydrogen Safety Panel (HSP) of the June 1, 2019 hydrogen release incident at the Air Products and Chemicals Inc. (Air Products) hydrogen trailer transfill (transfill) facility located in Santa Clara, California. This review was requested by the California Energy Commission (CEC) in May 2020 and examines data from Air Products, and the Santa Clara Fire Department to provide an HSP perspective on the incident cause, response, and recommended follow-up actions. 

Mixing of hydrogen into natural gas, as a means of mitigating environmental concerns associated with the use of fossil fuels, poses a question of performance of appliances designed for use with natural gas, when fuelled by blends of hydrogen and natural gas. This study examines the performance of space and water heating appliances fuelled by methane as a natural gas proxy, and methane/hydrogen blends containing up to 15% hydrogen.

This document provides an example safety plan in Attachment A associated with hydrogen and fuel cells, where there is a significant flammability or explosive hazard from quantities, pressures, exposures, or other conditions. Hydrogen is unique among flammable gases in that small quantities may result in ignition or explosions. This example safety plan was developed by Pacific Northwest National Laboratories (PNNL) and its Hydrogen Safety Panel (HSP) members to assist entities working with hydrogen to ensure the protection of life, property, and the environment.

The Hydrogen Safety Panel was established by the U.S. Department of Energy (DOE) to provide independent safety reviews and guidance to contractors in the DOE Hydrogen and Fuel Cells Program. In September 2017, the panel set up a task group to compile select hydrogen incidents from the H2Tools.org Lessons Learned database (https://h2tools.org/lessons) in a publication form for written reference, that are most pertinent to various types of DOE contractor projects. This report is the result of the task group’s work.

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.
