PROJECT - Gasification plant for Huntsman site?


A major waste-to-energy demonstration project could be built at the former Huntsman Tioxide plant in Grimsby - depending on the soon-to-be-decided outcome of a competition run by the Energy Technologies Institute (ETI). 
 
Dutch company Royal Dahlman is working with Grimley Smith Associates on the project to produce electricity using a gasification process, from domestic or commercial waste.
 
The scheme has been shortlisted in a £2.8-million competition run by the ETI, which last April selected Royal Dahlman as one of three technology proposals based upon:

- Full integration of waste segregation, gasification, gas clean up and power generation.
- Typical UK waste as fuel.
- Technology that is commercially viable at 5 to 20 MWe scale.
- Robust operability.
- An overall net electric efficiency above 25%.
 
The plant design is based upon MILENA gasification and OLGA gas cleaning (tar removal) technology. Both are patented inventions of ECN, further developed in cooperation with Royal Dahlman.
 
The design produces a clean gas with a high methane content, while its high energy value allows for efficient utilisation in a gas turbine combined cycle (IGCC), the Dutch company claims.
 
The proposed demonstration plant will have an net electrical output of 7MW, which is commercially viable in the UK. This plant will be the stepping stone to bigger and even more efficient waste fuelled IGCC plants.
