4 Torrefaction and gasification. Essential steps towards modular biobased solutions

5 Biomass gasification will play an important role in our circular decentralized biobased society. ; Drivers towards circular, decentralized biobased society: More competition; Lower cost infrastructure; More efficient use of resources; Sustainable

6 Dilemma s that need to be resolved for the creation of a sustainable biobased economy. Logistic dilemma s: Low energy density Regional supply chains Biodegradable/rotting Lack of scalability; 10 MWth requires mt of fresh biomass (i.e truck-loads) Biomass properties dilemma s: Heterogeneous feedstock Low grindability High moisture content Variability is a huge challenge for an 8000 hours/year, continuous and stable operation Economical dilemma s: Low value creation by conversion to energy Bankability of projects Modularity Low prices fossil alternatives Price, supply and quality security Gasification dilemma s: Low Temperature(<700 C): tars, no slag High temperature (>1000 C): slag, little or no tars Mid temperature ( C): slagging and tars

7 Solution 1: Biomass is not a fuel torrefied biomass is. A wide variety of feedstock can be converted into a high performance commodity. Y Y Y Y Y Y Tough Fibrous Hydrophilic Biodegradable Heterogeneous Poor energy density N N N N N N All ligno-cellulosic feedstock(wood, herbaceous,etc) can be torrefied and turned into stable biocoal Typical thermal efficiency torrefaction process is approxamitely 90% Bulk energy density feedstock: 1-3 GJ/m 3. Torrefied biomass: GJ/m 3

8 Solution 2: mitigate three fundamental process risks which are often encountered in traditional biomass gasification. Torrgas unique process design mitigates three fundamental risks which are often encountered in traditional biomass gasification: 1. Feed continuity: torrgas delivers a stable and efficient operation by applying homogeneous, high energy density, moisture free torrefied biomass. 2. Slagging (melting ash): which has significant negative impact on both the Capex and Opex of a gasifyer: torrgas technology circumvents slagging by immobilizing char. 3. Expensive tar cleaning: this is avoided by complete cracking of tars in the second step gasification.

9 Solution 4: high value creation and market flexibility in final products. Engineered carbon combined with tar, nitrogen free syngas. Engineered carbon Tar, nitrogen free syngas 1. Activated carbon market: water and flue-gas cleaning. 2. Soil Enhancer (biochar): a high-carbon soil supplement that retains water, microbes and nutrients. 3. Metallurgical char: high purity biochar can produce high purity steel with low carbon footprint. 4. Petcoke replacement for producers (Titanium, Silicon Carbide) requiring low sulfur petcoke. Syngas 5. BBQ-briquettes: the high carbon content / low volatile content makes it an ideal recreational fuel. 6. Filler in compounding industry (cars, construction)
