OHD (Oxidative Hydrothermal Dissolution)

Oxidative Hydrothermal Dissolution (OHD) is a novel technology developed at SIU that uses coal in an entirely new way - dissolving the coal in water at high temperature and pressure. OHD converts the coal to products that can be used to make fuels, or can be purified and used to make polymers like polyesters for a wide range of end products. OHD does not require expensive or toxic catalysts or solvents, produces very little carbon dioxide, and does not produce other potentially harmful emissions usually associated with conventional uses of coal (such as combustion for electricity generation).

SIU has licensed this technology to a spin-off company called Thermaquatica LLC, which is now pushing ahead with further development aimed at scale-up and commercial deployment.

Dr. Ken B. Anderson, a Professor of Geology, is founder and CEO of Thermaquatica Inc. He developed the OHD concept, and has served as principal investigator on grants funded by the State of Illinois to explore the concept, develop the fundamental technology, and he is now overseeing efforts to scale up the technology for commercialization. He is an organic geochemist with more than 20 years experience in coal science and related areas.
