Coskata's fully-integrated demonstration-scale facility, Lighthouse, represents the successful scale-up of Coskata's feedstock flexible technology, and was a critical step in the development and demonstration of the Coskata technology platform.  The facility is located in Madison, Pennsylvania.

Lighthouse was designed, engineered and constructed to enable a linear scale-up to Coskata’s first commercial production facility.

As one of the largest syngas fermentation facilities in the world, based on production capacity, Lighthouse has accumulated more than 15,000 operating hours. Lighthouse has produced ethanol from natural gas, wood chips, and simulated waste materials.
