The Koehler Group is to convert its power plant at the Koehler Paper site in Greiz, Germany, from pulverised lignite (coal) to fine wood fraction fuel.
The team at Koehler Renewable Energy, part of the Koehler Group, have developed an innovative technique that will allow a type of biomass to be used as fuel in the existing coal-fired power plant in a ‘completely new way’.
The plant’s conversion from lignite to fine wood fraction as the fuel is part of the group’s climate strategy, helping the company to produce more energy from renewable sources by 2030 than is required for its paper production operations.
In total, the conversion will save 24,000 tonnes of CO2 emissions per year at the site. Additionally, converting the fuel will also significantly reduce sulphurous emissions and pollutants compared with pulverised lignite.
Structural changes at the power plant and the additional engineering required are set to start in October and will be completed by May 2022. The plant is expected to start operating with the new, sustainable fuel in June 2022.
