Energy efficient negative emissions from agricultural sector

Agricultural and farming sector account for 13% of the total greenhouse gas emissions in Sweden, mainly containing CH4 and N2O. This project proposes a novel direct air capture (DAC) concept to mitigate CH4, N2O and CO2 emissions at lower energy demand and without affecting the practices in agriculture/farming.

Two cows in the field. Agricultural and farming sector account for 13% of the total greenhouse gas emissions in Sweden.

We aim to develop techno-economic-environmental-policy framework in close interaction with stakeholders (farmers and policymakers) to analyze the opportunities with DAC against other negative emission technologies (NETs) like BECCS. This is interdisciplinary collaboration between KTH, SLU and Uppsala Universities.

Method

The important methodologies will be thermodynamic modeling & simulation for
techno-economic analysis, life cycle analysis (LCA) to assess and optimize environmental impact, and stakeholder interviews and policy analysis to explore social acceptability and policy incentives.

Project plan

  1. Phd Project 1: Process design and techno-economic analysis (KTH)
  2. Phd Project 2: Socio-economic conditions and policy analysis(UU)
  3. Phd Project 3: Life cycle assessment and energy systems modeling (SLU) 
     

Project duration and financier

Project is financed by the Swedish Energy Agency and is estimated to run 2020 - 2024.
