NW Natural Gas has initiated a pilot program in Portland to blend small amounts of hydrogen into its consumer gas. This program serves as a step towards finding cleaner alternatives to methane, a potent greenhouse gas commonly used for heating, cooking, and industrial processes. Hydrogen, a promising candidate for a sustainable fuel source, offers the potential to reduce greenhouse gas emissions without significant infrastructure modifications.
Partnering with Seattle-based Modern Hydrogen, NW Natural will utilize the company’s methane pyrolysis technology in a three-year pilot project. This innovative process breaks down methane into solid carbon and hydrogen gas. The solid carbon collected during this process will be used for asphalt production, while the hydrogen will be blended into NW Natural’s supply of natural gas.
Blending small amounts of hydrogen into the existing natural gas infrastructure allows for emission reductions without compromising the integrity of current pipelines. While pure hydrogen can present challenges due to its higher leak-prone and ignition tendencies compared to methane, blending hydrogen at a 0.2% rate minimizes these concerns. According to a U.S. Department of Energy report, the maximum safe proportion of hydrogen can reach up to 15-20% depending on the materials and construction of the pipes.
NW Natural’s pilot program highlights the potential of hydrogen as a cleaner alternative in the energy industry. As the utility envisions higher blending rates in the future, this initiative paves the way for more extensive use of hydrogen in consumer gas supplies. By embracing hydrogen as a replacement for methane, NW Natural demonstrates its commitment to a greener future, reducing greenhouse gas emissions and combating climate change.
