The interesting angle

Founded 2007 as an in-house engineering partner of CSU's Energy Institute at the Powerhouse Energy Campus; has completed 450+ projects for DOE, DOD, national labs, and private companies; named to the 2024 Global Cleantech 100 and ranked #24 on Time's Top GreenTech Companies list; functions as an outsourced R&D team for other climate tech startups rather than selling its own product — worth disambiguating from the similarly-named "C-Zero" (Santa Barbara methane pyrolysis startup)
