Columbus-based pH Matter develops and manufactures carbon-based materials and catalysts for fuel cells, batteries, electrolysis and other emerging energy applications. Co-founded by Paul Matter and Chris Holt, the company combines materials research with electrode processing, electrochemical testing and commercial-scale production. Its catalyst work has earned U.S. Department of Energy recognition, and in 2024 pH Matter received $7.2 million in DOE funding to scale fuel-cell materials for heavy-duty transportation and hydrogen generation.
NAWAHNAWAH develops, architects, and manufactures vertically aligned multi-walled carbon nanotube materials and related architectured nanomaterials. Its products support next-generation composites, fuel cells, electrolysers, and catalyst systems, with manufacturing plants in Rousset, France, and Dayton-area Ohio, USA.ENGLEWOOD, OH
NeoGraf Solutions, LLCTracing its graphite work to a Cleveland carbon company founded in 1881, NeoGraf Solutions manufactures specialty carbon and graphite materials from its headquarters in northeast Ohio. Formed as a stand-alone company in 2017, it combines in-house research, development and manufacturing to make flexible graphite sheets, powders and related materials for demanding uses such as thermal management, industrial sealing and fuel-cell flow-field plates. Its products have supported applications ranging from smartphones and marine batteries to the Hubble Space Telescope and International Space Station.LAKEWOOD, OH
AvCarb Material SolutionsWith roots in aerospace engineering stretching back more than 60 years—including heat shields used on Apollo lunar missions—AvCarb Material Solutions manufactures engineered carbon materials for clean-energy systems, transportation, and other demanding applications. The Lowell company is particularly known for gas diffusion layers developed through decades of collaboration with fuel-cell manufacturers, alongside woven carbon materials used in high-energy friction systems and fishing-reel drag washers. AvCarb is certified to ISO 9001:2015.WADSWORTH, OH
Stratus MaterialsFounded in early 2022 by battery expert and Carnegie Mellon professor Dr. Jay Whitacre, Pittsburgh-based Stratus Materials develops and produces LXMO™, a lithium manganese-rich, cobalt-free cathode material for lithium-ion batteries. The company is building domestic supply for electric vehicles and energy storage, producing LXMO on a 1-ton-per-year pre-pilot line while moving toward a 30-plus-ton pilot operation. Its materials are designed as a drop-in alternative for existing battery manufacturing processes.PITTSBURGH, PA
