Presentation Transcript

  1. H2 in the Pipes:The Natural Gas System as a Hydrogen Enabler • Anna Chittum • May 20, 2019

  2. NW Natural Gas System • 160 year old Oregon company • Serve over 2.1 Million Oregonians – more than half the state’s population • Tightest system in the country 1

  3. NW Natural Gas System • How is the gas system relevant to hydrogen production? • Highly flexible sink • Mist Storage: 16 BCF of storage capacity • Equivalent to 20% of ALL the gas we sell for our sales customers in a year • 22,000 miles of pipe that can operate within pressure bands (as opposed to electric system) • Natural gas utilities in Oregon will likely be operating under policy and regulatory frameworks that allow them to procure renewable gas for their customers at a premium rate; renewable gas is inclusive of renewable hydrogen • Long term contracts and interconnection

  4. Impact of New Policy • Oregon H.B. 2020: The “cap-and-trade” bill • Passed out of its policy committee last week • Gas utilities can: • Buy renewable H2 • Invest in H2 fueling infrastructure • Oregon S.B. 98: The optional renewable gas program • Passed out of its policy committee earlier this session • Gas utilities can: • Procure renewable gas – inclusive of renewable hydrogen – toward optional volumetric targets • 2025: 10% 2035: 20% 2045: 30%

  6. Seasonal Energy Storage Opportunities Source: European Power to Gas/DNV GL Pacific Northwest energy needs are seasonal and concentrated in the winter Long-term storage: • Pumped storage: $2,875/kW • Power to gas: $800/kW fully installed and coming down Source: Dragoon 2018

  7. Is Hydrogen Safe?

  8. Is Hydrogen Safe? • Hawaii Gas: has about 15% hydrogen blended into gas system • U.K: HyDeploy at Keele University to test 20% hydrogen this summer • U.K: H21 Project with Northern Gas Networks to deploy a 100% hydrogen gas grid in Leeds • Several hydrogen safety efforts at national labs in U.S. and other research entities (GTI) • Canadian Gas Association literature review on hydrogen blending

  9. What is NW Natural Doing? • 2000: completely eliminated cast iron pipes • 2016: finished polyethylene pipe replacements • 2017: Low Carbon Pathway established • 2017: Commissioned white paper on P2G from Flink Energy • 2018: committed R&D funds to dedicated research around leak detection and odorant with Oregon State University • 2018: commissioned Deep Decarbonization study with E3 • 2019: submitting federal grant proposal to deploy pilot project, including safety work and pipeline blending research

  10. Pilot Project in Eugene • First power-to-gas project to generate renewable hydrogen and inject into commercial distribution line in United States • Install first public hydrogen fueling station in Oregon • Explore specific hydrogen safety issues, integration with renewable resources • Partners are many, but include the Eugene Water and Electric Board, Hitachi Zosen Inova, and Oregon State University • Goal: show how integration of gas and electric systems allows for greater flexibility and utilization of renewable resources
