A Harmony Project at the centre of a personal commitment
“This Harmony Project is the achievement that I am most proud of in my entire career,” he says with enthusiasm. It is the first time that we have been able to transform an electric power plant into an entirely ecological power plant.”
After having defined wood as the best solution, in a heavily wooded region of northern Switzerland, there were still technical problems to be overcome. “Our biggest problem was how to measure the amount of energy in the wood, with suppliers being paid for the energy their wood provides, not the quantity,” Roland Dietler explains. An on-board measurement system on lorries was therefore designed, to calculate the amount of energy before and after delivery to customers, a world first. The Swiss engineer is proud of his work: “It was a very large-scale project, one of the largest low-emission gas boiler projects. The complex included a biomass boiler, three gas boilers, a steam turbine and a huge biomass bunker,” he says.
Roland Dietler does not see the energy transition solely from a professional point of view. He has been a Greenpeace member for 30 years, so it is a lifelong commitment for him. “I would like to see the green revolution unfold in my lifetime, meaning that we no longer use oil at all. We have already been able to do without it and I hope we will be able to do without it for a long time. We have to agree to change our state of mind with regard to energy.”
About: ENGIE x DSP Nutritional Products Harmony ProjectThe Sisslerfeld wood-fired power station, located in the canton of Aargau on the German border, is a flagship project for the transition to zero-carbon energy. This “as a service” project for industry, which includes an investment of 60 million Swiss francs, reduces CO2 emissions by 50,000 tonnes a year. This power plant, built to replace an old fossil-fuel plant and inaugurated at the end of 2018, produces 267 GWh of heat and 42 GWh of electricity per year from wood chips from the surrounding forests, within an average radius of 80 to 100 km. The DSM Nutritional Products factory buys heat from this plant.
