Feasibility Study on Gasification of Hybrid Willow(ST6743-1)

Alfred University


A compact gasification process that lends itself to small, modular installations, but also may be utility-scaled, has been developed. The process was developed to convert a wide range of solid feeds, including low-quality coal or wastes, into fuel gas and valuable by-products like foam glass or aggregate. The gas can be used for site heating or electricity generation via a microturbine.

Project Description

This feasibility study determined an innovative high temperature air blown gasification process can convert willow and agricultural residues to medium grade fuel gas.


The gasifier has the potential for better conversion efficiency compared to a conventional gasifier. Unlike other gasifiers that need to use oxygen to help reactions reach completion, this gasifier can use high temperature air, a more economical choice for converting low grade feedstocks to gas.

Project Results

The work brought the technology to a stage ready for prototypic demonstration testing by exploring technological aspects of co-gasifying willow and other fuels, and practical, economical, and regulatory aspects of constructing and operating a gasifier. In addition, work explored retrofit applications for existing natural gas power plants, including surveying generators and identifying suitable candidates, possibly with interest in integrating with integrated gasification combined cycle (IGCC) systems to make fuel gas from coal.
