NWN Gas Power to Gas: Update
MWMC Staff attended a meeting on April 21, 2020 where NWN proposed a Power to Gas Project.
Power to Gas technology would use excess electrical power to produce gas.
The project would use off peak hydroelectric power to produce hydrogen through electrolysis at an onsite facility (approximately 50,000SF).
Hydrogen would then be mixed in a reactor with waste CO2 from the RNG processing (about 40% of the volume) to produce synthetic methane to be fed into the NWN gas system.
Synthetic Methane would have brown gas and California/OR LCFS value, but no Renewable Fuels Standard (RFS- RINs) value.
There is not an similar operating facility within the United States at this time.
NWN and others would provide the capital for the project and the split of revenue would need to be negotiated.

NWN Gas Power to Gas: Feedback
Staff found this technology fascinating, but believe it best to prove current RNG process prior to looking further into power to gas technology.
The power to gas technology utilizing hydrogen is just emerging, and staff thinks it would be suitable for further evaluation once the MWMC’s RNG project is up and running with a year
of successful operations.
Staff invites Commission feedback and discussion on this matter.
