New Concepts for Biofuels in Transportation: Biomass-Based Methanol Production and Reduced Emissions in Advanced Vehicles.

摘要

In this study, new concepts for methanol and hydrogen production from wood-based biomass were evaluated and the climate benefits that could be achieved from the use of these fuels in advanced vehicles were estimated. In the process concepts chosen for the techno-economic assessment, methanol or hydrogen production is integrated to CHP production of an existing pulp mill. The production of methanol from biomass requires a fairly advanced gasification and gas cleaning process in order to meet the requirements of the synthesis process. The hydrogen production process is somewhat simpler. However, the evaluation of the hydrogen production processes was, due to priorities set in the project, based on a more shallow evaluation. Two methanol production concepts were selected for evaluation: methanol production integrated to an existing pulp mill in Finland and in the Far East. Performance and costs of corresponding hydrogen production were also estimated roughly for the Finnish case.
