Award finalist: Promus Energy

December 23, 2022

Washington’s Commissioner of Public Lands, Hilary Franz, will present the second annual David & Patricia Giuliani Clean Energy Entrepreneur Award on January 5th, atop Seattle’s Columbia Tower, at the Future of Carbon Policy Forum.

The award, named after our organization’s founder and his wife, recognizes meaningful advances in clean energy innovation. The inaugural winner was Kenworth Trucks, presented by Governor Jay Inslee. 

Join us there to find out which of these five finalists will win this year’s award:

Promus Energy makes Washington dairies more environmentally, economically, and socially sustainable, with equipment that anaerobically digests manure to produce renewable natural gas (RNG) and power for electric vehicles (EVs).

Promus is also one of three partners in Koe Energy LLC, which is a fully integrated, “cows to cars” company producing GHG-negative power for a rapidly expanding network of EV fast charging stations in Pacific coast states. 

According to Promus, dairies can be the source of substantial GHG emissions, water pollution, odor, pathogens, and other environmental and community problems. The Promus anaerobic digester removes carbon in the form of biogas that would otherwise be emitted from dairy lagoons into the atmosphere as powerful GHGs. Cutting off these baseline emissions makes the produced “fuel” (RNG or electricity from biogas) deeply GHG negative. The dairy shares in the value Promus gets from selling the carbon credits and commodity fuel. In the near future, Promus anticipates that low-carbon dairies will be rewarded for their environmental stewardship with premium pricing and market access for low-CI (carbon intensity) milk, cheese, and other products.

When Clean & Prosperous Washington Institute led a study mission to California, we saw first-hand how ranchers in the Central Valley are incorporating dairy digesters into their operations, and how that is a win-win proposition for the ranchers and the state. 

Will it be a win for Promus Energy? Join us on January 5th to find out!
