Two-stage gasification technology – Torrgas

Scale-up of biomethane production

Torrefaction is a method to produce biofuel from woody residues. The Torrgas process converts these residues via a two-stage gasification technology into a biofuel. The process has no tar and slag formation. Activated carbon is produced in the first step in the gasification process, which can be used for applications such as water purification, soil improver, or bio-composite. The second step creates syngas, that can be converted into green gas and hydrogen via gas conditioning and synthesis. In addition, pure CO2 can be separated from the syngas for use in the soft drink industry and greenhouse horticulture. The Torrgas project aims to realize a 20 MW commercial gasification installation based on woody residual flows in Delfzijl in the Northern Netherlands. The project consists of the construction of a gasification installation, a gas cleaning and a methanation system. With the aim of supplying green gas to the natural gas network and steam to the local steam network. Gasunie New Energy is developing this installation in close collaboration with Torrgas and other project partners. The final preparations will be made in the second half of 2020 with the aim of starting construction of the installation in Delfzijl in 2021. The plant is expected to become operational in the first half of 2021.
