The Pyrolysis-Bioenergy-Biochar Pathway to Carbon-Negative Energy
An integrated pyrolysis-bioenergy-biochar platform can provide multiple pathways for production of sustainable, carbon-negative fuels, power, chemicals, products, and biochar.
Two pathways are being studied:
- A biochar & biofuel scenario, in which bio-oil is hydrotreated and then refined to produce both gasoline and diesel.
- A biochar & bio-power scenario, in which a solid fuel prepared from bio-oil, known as Lignocol, is used as a substitute for coal in power generation.
We are performing techno-economic analysis to assess economic performance of pyrolysis plants and life-cycle assessments to determine net GHG emissions. In partnership with Stine Seed Farms and Frontline Bioenergy, we are engineering, optimizing, and demonstrating a 50 ton/day modular pyrolyzer.
Pilot-Scale Pyrolyzer
APSIM Biochar Module
We have designed, built, and are testing a biochar module within the Agricultural Production Systems sIMulator (APSIM), a widely used cropping systems model. This effort systemizes the science underlying complex soil-biochar-crop-climate interactions and provides predictions of agronomic and environmental responses to biochar applications.
Biochar Application
To further evaluate the impact of biochar amendments on various cropping systems, soil quality parameters, and environmental outcomes, we are also conducting laboratory, greenhouse, and field plot studies.
Biochar Test Plots
This effort includes researchers from Iowa State University, University of California, Berkeley, and Indiana University – Purdue University Indianapolis and is funded by the Global Climate and Energy Project (GCEP) at Stanford University.
