The license is currently being negotiated to define the royalty structure and is expected to be finalized next month. Arch has been a shareholder of ADA since 2003 when the company spun-out as a separate public entity.

John Eaves, president and CEO of Arch, said: “As part of our commitment to clean energy, we are pleased to provide this additional investment in ADA, a leader in developing clean coal technology. We believe helping finance advanced technologies developed by ADA will enhance the environmental performance of our coals.”

ADA claims that it has been successful at developing technologies that improve the performance of coals from Wyoming’s Powder river basin (PRB). In addition to flue gas conditioning chemicals used to aid in the collection of ash from PRB coals, the company also developed a brominated activated carbon technology that provides a means of achieving 90% removal of mercury emissions from PRB coals and CyClean technology, a coal additive that improves combustion of PRB coals in cyclone boilers resulting in efficiency and reduced emissions of mercury and nitrogen oxides.

Mike Durham, president and CEO of ADA, said: “This investment will continue our long-standing relationship with Arch and allow the company to fund opportunities that have the potential for significant near-term increases in revenues and earnings such as CyClean.”
