MIP Torrefaction


What is Microwave Induced Plasma Torrefaction?

The Plasmergy MIP Torrefaction process is a novel technology to enable low energy generation of “bio-coal” from biomass. The Torrefaction process uses low temperatures to heat wood, in the absence of oxygen, to produce a char-like fuel that, once pelletised, has properties similar to coal. The increase in the energy density of torrefied biomass as well its enhanced physical properties for fuel handling and storage, therefore presents the power generation sector with an attractive alternative to woody biomass for co-firing.



Technical & Commercial Advantages
Ability to torrefy biomass pellets directly
Rapid start-up and shut down of the technology
Avoid an energy intensive process step in the conventional torrified biomass pellet supply chain
Ability to integrate MIP Torrefaction technology into a wood pelleting facility
Applications and Markets

Co-firing plants in the UK typically generate up to 6% of their power using biomass. Aberthaw Power Station in Wales is typical of the industry in the UK and generates 1,555 MW of power for export to the grid, 55 MW of which is generated by co-firing coal with biomass. Using Aberthaw as an example co-firing plant and switching from woody biomass to our torrified pellets brings the following benefits.



24% increase in electricity generation
...when comparing against an equivalent volume of chipped biomass
45% reduction in required biogenic feedstock
...to produce an equivalent amount of electricity
Significant transport costs savings
...as a consequence of higher bulk density and energy density than chipped biomass as well as significant savings from transporting a dry fuel compared to wood (30% – 40% moisture)
Improved financial returns
...from incentives for renewable energy generation
