Yes, NW Natural has started blending hydrogen into gas sent to some Portland customers

NW Natural has commenced an innovative pilot program that blends hydrogen into the natural gas supply for select customers in Southeast Portland, initially at a 0. 2% rate. This initiative, launched in collaboration with Modern Hydrogen, employs a methane pyrolysis process that converts methane into hydrogen and solid carbon, promoting cleaner energy use. As natural gas is predominantly methane and contributes significantly to greenhouse gas emissions, the blending of hydrogen offers a promising path toward reducing environmental impact. Hydrogen combustion produces no harmful emissions, but its properties present challenges, including increased likelihood of leaks and potential degradation of existing pipelines.

The U. S. Department of Energy has indicated that the safe blending limit for hydrogen can reach up to 20% depending on pipeline materials. NW Natural's pilot program is part of a broader trend in utilities seeking to leverage existing gas infrastructure while transitioning to cleaner fuels. The utility envisions scaling up the hydrogen blending rate in subsequent phases of the project, reflecting a commitment to sustainable energy practices.

This development aligns with increasing discussions around hydrogen's role in the future of energy, particularly in urban settings like Portland.
