Why Us

Competitive Advantage


The Pennsaco technology has been thoroughly tested and United States Environmental Protection Agency validated, ensuring its practical application in a wide range of plant environments. Our process is tried and true, and its efficiency is well-documented through more than a dozen existing & new patents.


One system, two pathways.  Pennsaco has pioneered production of green hydrogen from waste through one system with two patented pathways that produce low cost, carbon negative, pressurized hydrogen at rates 30% greater than current state of the art.


Pennsaco’s management has decades of proven project experience capable of designing, building, and operating commercial plants for waste management and renewable energy.


Pennsaco’s technology is feedstock and product flexible, scalable, customizable to local needs, and serves multiple global markets worth trillions of dollars.


Pennsaco Technologies can be deployed anywhere in the world, advancing 12 of the 17 United Nations Sustainable Development Goals with each facility and generating billions of dollars of wealth creation.



Pennsaco overcomes two significant challenges in the production of complex hydrocarbons from biomass: the purity of gas streams and the reliability and scalability of equipment.
With patents for generating hydrogen and carbon monoxide outside typical thermal processes, Pennsaco produces high purity gas streams that can be combined into dozens of compounds.  Other systems generate adulterated syngas streams that require expensive separation and cleaning before they can be used.  The Pennsaco continuous flow process has a proven capacity of 75,000 tons/year, and is scalable to many times that volume.  By combining high thermal efficiency – up to 95% of feedstock BTU value captured – with patents for increasing BTU to megawatt conversion rates, Pennsaco’s system is energy self-sufficient.  Commercially proven trade secrets enable years of uninterrupted operations. A single site converts hundreds of thousands of tons of waste and CO2 that would otherwise end up as landfill or greenhouse gases. These inputs convert into hydrogen, biochemicals, advanced biofuels, activated carbon, and biochar as carbon neutral or carbon negative products.
