Hydrogen pilots

Hydrogen pilot at PSE’s Georgetown Training Facility – April 2021

PSE conducted its first hydrogen pilot at its Georgetown Training Facility in Seattle, in April 2021.

As a part of this pilot, the testing team performed a series of tests using 5%, 10%, and 15% hydrogen/natural gas blends and compared the results with 100% natural gas. For each of these scenarios, the system was tested for leaks, air quality after combustion, gas quality, and impact on the appliances used.

The tests allow PSE to become familiar with hydrogen natural gas mixes, protocols for its safe use, collect quantitative and qualitative data to infer system response, and understand the operational, safety, and customer use challenges associated with its use.
