CEG and TSE trial 1,000 tonnes of Renewable Black Pellets at TSE’s Naantali power station in Finland

Clean Electricity Generation Ltd (CEG) and Turun Seudun Energiantuotanto Oy (TSE) are
pleased to announce the successful logistics, handling and combustion trial of over 1,000
tonnes of CEG Renewable Black Pellets at TSE’s coal-fired power unit Na2 in Naantali power
plant, Finland. The pellets, produced from sustainably sourced biomass, served as a drop-in
substitute for fossil coal in the co-firing trial.

CEG Renewable Black Pellets were produced at CEG’s High Temperature Torrefaction facility
in Derby, UK, and transported by ship to Naantali, Finland. In Naantali, the pellets were stored
outdoors, in the power station’s existing coal yard, uncovered and exposed to rain and normal
autumn weather conditions. The pellets were then conveyed, using legacy coal conveyors, to
the unit Na2 power block’s coal silos and mills, and ultimately the coal-fired boiler unit Na2.
During the trial, TSE employed the plant’s existing infrastructure designed for fossil coal; the
equipment was not modified for biomass.
