Please, allow the students from the Washington Innovation for Sustainable Energy (WISE) club to present Project Mobius, a hydrogen power-to-gas system for Spokane’s Riverfront Park. The project is the club’s submission for the 2017-2018 Hydrogen Education Foundation contest “Designing a power-to-gas system“:
The team members include: Mathew Hunt, Lee Taylor, Ryan Hamilton, Timothy Eckhart, Ashley Mills, Chloe Nichol, Austin Anderson, Austin Dowell, Joseph Ostheller, Nicholas Potter, and Spencer Seeberger. The team was advised by Ian Richardson and Jake Leachman. External project stakeholders that provided advise on the project include Steve Wenke at Avista Corporation, Gary Higgenbottom from ITM-Power, William Fuglevand at Plug Power, and Kim Zentz of the Spokane SmartCity/Urbanova project and WSU.

The team selected Riverfront Park in downtown Spokane to be the location of the system due to the history of the site with the 1974 World’s Fair, which was the first environmentally themed World’s Fair. Avista has an available water turbine in a nearby diversion dam that can provide 576 kW of power to the electrolyzer, which will produce 225 kg of hydrogen per day. The hydrogen can be injected into the natural gas grid or used for fueling hydrogen fuel-cell powered vehicles. The project is estimated to displace over 2000 tonnes of carbon dioxide emissions every year, or the estimated emissions of 430 cars.
The shape of the electrolyzer container and the two adjacent 20′ hydrogen storage containers is a Mobius strip from the ’74 World’s Fair — to symbolize the never-ending recycling of energy epitomized by hydrogen from water.
Regardless of whether they win the competition, the team may have started the first large-scale public hydrogen project for the Pacific Northwest!
