Summary
Tampere Electric Company (Tampereen Sähkölaitos Oy) is to deliver carbon-negative district heating to its customers in the Hiedanranta city district of Tampere via its district heating network.
This will be the first occasion that carbon-negative district heating is being produced commercially in Finland, and the utility is purchasing the heating from Carbofex Oy company, which will produce the district heating alongside biochar, its main product. Hiedanranta will act as a development platform in the project.
Carbon-negative equals climate positive
Carbon-negative sometimes referred to as “climate positive” goes a step beyond the measures taken to be carbon neutral (ie net zero carbon emissions) and means more carbon dioxide is being removed from the atmosphere than is being produced. Meanwhile, district heating networks are regarded as one of the most energy-saving ways of heating homes in densely populated areas.
The Carbofex factory heats up wood from the Tampere region and turns it into a mineral, in this case biochar. This happens through pyrolysis. When biochar is used as a soil amendment, for example in landscaping work, it will sequester (isolate) carbon permanently in the soil. The production process also produces waste heat, which will be used for district heating.
