Successful test with innovative renewable energy source at Amer power plant
Den Bosch – A consortium consisting of Topell Energy, three electricity companies, Essent, Nuon and GDF SUEZ and ECN has successfully completed a large scale co-firing test with torrefied pellets at the Amer power plant in Geertruidenberg. The co-firing test was conducted under the ‘Top consortium for Knowledge and Innovation Bio-based Economy’ (TKI BBE)’ initiative. After this successful trial, some of the parties are now discussing the next steps to mobilise larger quantities of torrefied pellets for the production of green electricity, in view of the requisites of the Dutch Energy Agreement which will come into force in 2015.
Alternative to conventional wood pellets
In the trial, a total of 2,300 tons of ‘biopellets’ have been successfully transported, handled, co-milled and co-fired to produce green electricity. Rob Voncken, CEO of Topell Energy comments on the process: “The co-firing test took place in percentages ranging between 5% and 25% (on one mill) between 1st November and 30th December 2013 at the Amer power plant.
No adverse effect on milling and burning was detected in any of the tests. The trial therefore confirms that high quality ‘biopellets’ can be produced and co-fired at large commercial scale. Together with its high energy content and density, this confirmation makes torrefied biomass a potential better alternative to conventional wood pellets to substitute fossil fuels.’
Bio-based chemicals and materials
Kees de Gooijer, director of the TKI BBE programme, says:
“I am very pleased with the positive outcome of the co-firing trial. They constitute a convincing proof that torrefied biomass can contribute meaningfully to the Energy Agreement targets of the Dutch government – 25 PJ of electricity generated from biomass by 2020 – aimed at promoting green electricity and at phasing out fossil fuels.
“We also view this torrefaction technology as an important enabling technology for the future production of bio-based chemicals and materials”.
Essent is the largest producer of (renewable) energy in The Netherlands and delivers electricity, gas and heat to private and business customers. The company regards the Netherlands and Belgium as its home market. The total production capacity of Essent/RWE in The Netherlands is 4,500 MW, about 1.600 MW is currently under construction. In 2012, Essent was accounted for more than a fifth of all sustainably produced electricity in the Netherlands. The company employs 3,500 people (FTE).

About Topell Energy
Topell Energy is a Dutch clean technology company. Topell Energy has developed a cutting edge process for the production of high value solid bio-fuel from woody biomass. This process is known as torrefaction and the solid bio-fuel is usually referred to as torrefied biomass, black pellets, or biocoal.
Torrefaction of biomass results in ability to use lower quality feedstock, reduced logistics costs as well as lower capex at the power plant for handling bio-fuel. Torrefaction is instrumental in unlocking the potential of biomass for energy production. Besides this, torrefaction also creates the opportunity to accelerate the use of biomass as feedstock for large scale gasification to produce bio-based chemicals and materials.
Topell Energy operates a commercial scale demonstration plant in Duiven, The Netherlands. The company is preparing the worldwide roll-out of its torrefaction technology by licensing its technology to bio-fuel producers.
About TKI BBE
The Dutch government has identified nine ‘top sectors’ in which national companies have a world-wide lead. The chemicals and energy sectors are two of them. The Top consortium for Knowledge and Innovation Bio-based Economy (TKI BBE) is an agency which coordinates the cross-sector programme to realize the Dutch bio-based economy.
The Dutch government is channelling funds through the TKI BBE to support projects which contribute to the green production of heat and power. The large scale co-firing test referred to above is part of a programme conducted by a consortium which obtained subsidies from TKI BBE over the course of 2013. Aside from the parties mentioned in this press release, the consortium also includes the Universiteit Twente, TU Delft, Torrcoal and Biolake.
Nuon is an energy company whose 4.800 employees serve 2.1 million consumers, businesses and organisations in the Netherlands. Its key commitment is to supply energy that is reliable, affordable and as clean as possible. Nuon produces and supplies gas, electricity, energy-related products, heat and natural cooling and helps customers to reduce their energy use. The company is part of Vattenfall.
