Sustainability Assessment of Innovative Energy Technologies - Integrated Biomass-based Production of Fuel, Electricity and Heat
Haase, M., Rösch, C.
The transformation of the energy system is crucial for the sustainable development of European countries. Innovative energy technologies can make an important contribution to increase the share of renewable energy, for example by using biomass instead of fossil resources. As part of the Helmholtz Initiative Energy System 2050 (ES2050), a cross-technology approach for the prospective sustainability assessment of technologies is developed. The paper presents the results from the indicator-based sustainability assessment of the thermochemical conversion of lignocellulosic biomass into fuel, electricity and heat (bioliq® process developed at KIT). The bioliq® process involves the decentralized pyrolysis of lignocellulosic residues into a transportable intermediate (biosyncrude) and the central production of syngas with subsequent fuel synthesis as well as the central production of electricity. The assessment system includes 13 environmental indicators, 2 economic indicators and 3 social issues and corresponding indicators. Assuming price projections and a conservative progress rate of 0.95 for investment expenditures, manufacturing costs of gasoline from straw are estimated with approximately 1,20 €/l for the year 2050. Comparing the yearly emissions from the industrial-scale production and use of bioliq® fuel and electricity to the emissions from the production and use of the same amount of conventional fuel and electricity (German electricity mix), the emissions of CO2-equivalents can be reduced by approx. 780 kt per year (62 %) for the year 2050. This estimate is based on a progress rate of 0.94 for agricultural machinery together with assumptions for future electricity and mobility mixes.
