About

ION Engineering is a clean technology company that develops post-combustion carbon capture technology for emissions reduction from industrial sources, particularly natural gas power generation. The company provides solvent-based carbon capture solutions designed for high capture efficiency and sustainability, offering design, engineering, and maintenance services to ensure project success. ION technology focuses on reducing the energy penalty and cost associated with carbon capture, making it economically viable for widespread deployment at power plants and industrial facilities. The company approach addresses the challenge of capturing CO2 from existing flue gas emissions, enabling retrofits of current infrastructure rather than requiring entirely new plant designs. Founded in 2008 and headquartered in Boulder, Colorado, ION Engineering has raised approximately $70.1 million through Series A funding from investors including Chevron, Carbon Direct Capital, SK Materials, and the U.S. Department of Energy.
