Biochar - systems analysis for climate change

Reference number
Coordinator Kungliga Tekniska Högskolan - KTH Avdelningen för industriell ekologi
Funding from Vinnova SEK 3 230 800
Project duration November 2016 - December 2021
Status Ongoing
Venture 2015-06858-en

Purpose and goal

Biochar is produced by heating of biomass with limited air supply (pyrolysis). Energy is released and char is produced, which sequesters carbon and reduces climate impact. The project aims at establishing a method for systematic evaluation of environmental impacts from systems that integrate biochar production through pyrolysis into current or future energy systems. In three case studies the environmental impacts and energy balance are calculated with life cycle assessment methodology.

Expected results and effects

In the project, environmental and energy impact of three biochar systems will be calculated in a life cycle perspective. A method will be developed for analysing and describing biochar systems, relevant or feasability studies of biochar projects. In Sweden, different pyrolysis and biochar systems are being planned, investigated and built by different actors, and this project will use the

Planned approach and implementation

A group of stakeholders, inkluding owners of production units, planners, biokol users and researchers will define the systems to investigate in each case study (feestock, conversion technology, biochar use, energy use). The energy balance and environmental benefits and risks will be evaluated by the researchers, using life cycle assessment. The results wil lbe commincated with the group, and conclusions drawn as preparation for the next case study.
