OCOchem wins contract extension to develop electrolyzer to make non-corrosive deicers for U.S. Army

OCOchem wins contract extension to develop electrolyzer to make non-corrosive deicers for U.S. Army

OCOchem wins an extension of the contract to develop a large-scale prototype electrolyzer to make non-corrosive deicing chemicals for the U.S. Army.

OCOchem has received an extension of its $1.1 million contract to develop a non-corrosive, chlorine-free deicer to protect military equipment from damage caused by rock salt or road salt. This new chemical process could save US state and local governments over $100 billion in annual maintenance costs related to corrosion and protect the environment and water supplies.

The U.S. military, as well as state and local governments in cold-weather environments, use chemical deicers to melt dangerous ice on roads, walkways, and runways. U.S. military facilities throughout the world rely on deicers to keep their bases operational and mission ready 24/7.

However, the most common de-icing chemicals used today, due to their historically lower costs, are chloride-based salts. These salts have negative effects on the environment and surrounding infrastructure after they are applied, dissolved, and dispersed, said Todd Brix, co-founder, and chief executive of Richland-based OCOchem.

Such negative effects include corrosion of vehicles, equipment, and metal components (like rebar and joints) used in bridges and transportation infrastructure, soil and drinking water contamination from chemical runoff, and vegetation damage. According to a report issued by the General Accounting Office in 2016, corrosion cost the U.S. Department of Defense nearly $21 billion in FY2011.

Beyond the U.S. Army and Department of Defense, the annual estimated economic cost of the negative effects of chloride-based de-icing chemicals exceeds $100 billion in the civilian economy of the United States.

OCOchem has created a cost-effective process to produce a non-corrosive potassium formate deicer using recycled CO2 emissions, water, potassium sulfate, and clean electricity. This can help reduce the $561 billion spent annually in the US on corrosion and slow down the deterioration of infrastructure.

Although other potassium formate deicers exist and are commonly used in airports and for home use, they are made from fossil fuels. OCOchem’s process greatly reduces the price by using abundant recycled CO2 to make it affordable.

With the U.S. Army grant, OCOchem in August built the first large-scale prototype-scale mobile Carbon Flux Electrolyzer™ that produces potassium formate in a ready-to-use liquid brine formulation for use as a corrosion-free deicer. The formate electrolyzer can fit on the back of a military vehicle, making it directly accessible to bases throughout the world.

The prototype – a wonder of electrical, chemical, and mechanical engineering invented, created, and demonstrated at OCOchem’s Richland headquarters — is the world’s first formate electrolyzer of this size. It is 18 times larger than the initial prototype developed by Brix and his team.

The new deicer – if widely adopted by the military and civilian users – has the potential to not only save U.S. taxpayers more than $100 billion per year through reduced corrosion, maintenance, and replacement costs currently caused by using chloride-based deicers but to also:

  • Enhance supply chain resilience and reduce logistics costs and risks by allowing the new de-icing chemicals to be made on-site at U.S. military bases.

  • Lower potassium formate costs by more than 30%, enabling expanded use.

  • Create a shorter and more resilient U.S.-only supply chain that does not rely on chemicals imported from abroad. Potassium formate would be produced on-site using OCOchem’s Carbon Flux Electrolyzer™ and U.S.-sourced recycled CO2, water, and potassium sulfate.

  • Cut environmental and water supply contamination and salination by reducing chloride salt-based deicer runoff.

  • Reduce CO2 emissions by capturing and recycling CO2 from on-base emission sources, such as diesel generators, natural gas turbines, and heaters.

  • Reduce overall CO2 emissions by more than 100 million tons per year in the United States (2% of annual U.S. greenhouse gas emissions) if traditional rock salt deicers are entirely replaced with this approach.

Todd Brix, co-founder and chief executive of Richland-based OCOchem, said.

The potential impact of this novel lower-cost carbon-neutral deicing manufacturing process delivers a triple benefit to national defense readiness, civilian customers, and the environment.

“We are excited to continue our efforts to further scale our formate electrolyzer technology to a commercial-ready system for the U.S. Army so that the new low-cost corrosion-free deicer can be used at U.S. military bases throughout the world and be deployed in the civilian sector to more affordably enhance safe travel and to protect and extend the longevity of our natural and built environment.”

About OCOchem

OCOchem is a venture-backed clean-tech start-up developing and commercializing technology that uses recycled carbon dioxide in the chemical structure of formates and formic acid, which can then be used to create less expensive and more environmentally friendly chemical solutions and also be converted to green hydrogen.

OCOchem has received R&D funding from the U.S. Department of Energy and Defense, ARPA-E, and is an inaugural member of Halliburton Labs. Founded in 2017 in the Pacific Northwest, OCOchem operates its principal R&D laboratories in Richland, Wash.
