RNG and Hydrogen Gas Interconnect

Renewable Natural Gas (RNG) or Hydrogen Gas NW Natural Pipeline Interconnect Services

An interconnect receipt point facility provides pipeline access for a new source of natural gas or hydrogen gas to be sold to the energy marketplace after being interconnected to NW Natural's distribution system. At NW Natural, we promote the injection and use of RNG (biomethane) and hydrogen gas for our customers. We are committed to interconnecting renewable energy projects that provide safe and reliable renewable energy that supports our region's climate goals.

How to start

Read and complete the RNG Producer Inquiry Form or the Hydrogen Gas Producer Inquiry Form which NW Natural will use for the initial evaluation of your RNG or hydrogen gas project’s potential connection to our system. Once the initial evaluation has been completed, we will schedule a time to meet and discuss the project in greater detail and answer any questions you may have.
