Application of pyrolysis products
Temperature Influence on Negative Emission Solar-Driven Biomass Pyrolysis Plant for Bio-Fuel and Biochar Coproduction: A Techno-Economic Analysis
Short Introductive summary
Conventional pyrolysis processes sustained by combustion of part of the feedstock/products are limited by the loss of part of the biogenic carbon as CO2, increasing costs and environmental impact. Within the Horizon Europe project PYSOLO, a 10 MW solar-driven fast pyrolysis plant integrated with a particle-based solar tower is proposed. Solar-heated particles act as heat carriers supplying the energy for the endothermic process, enabling flexible and continuous operation with thermal storage. Varying the pyrolyzer operating temperature affects both product yields and solar tower efficiency, revealing a trade-off between conversion performance and solar system design. This study optimizes the pyrolysis plant operating temperature by minimizing the bio-oil Minimum Fuel Selling Price (MFSP) benchmarking the system against a conventional pyrolysis plant, obtaining higher carbon efficiencies, higher negative CO2 emissions and lower MFSPs.
