Abstract
The purpose of the project is to select and validate technology concepts for the establishment of a Danish production of green synthetic fuels primarily for fuel cells. The feasibility of the selected concepts is assessed trough a techno-economical calculation, which includes mass and energy balances and economics including CAPEX and OPEX assessments. It is envisioned by the project partners that a production of green synthetic fuels, such as methanol, can 1) bring stability to a future electricity grid with a high share of renewable energy, 2) replace fossil fuels in the transport sector, and 3) boost Danish green technology export. In the project, two technology concepts were derived through carefully considerations and plenum discussions by the project group members: Concept 1): Methanol/DME Synthesis based on Electrolysis assisted Gasification of Wood. Concept 2): Methanol/DME synthesis based on biogas temporarily stored in the natural gas network. Concept 1) is clearly the most favored by the project group and is therefore analyzed for its techno-economic feasibility. Using mass and energy balances the technical perspectives of the concept were investigated, along with an economic breakdown of the CAPEX and OPEX cost of the methanol production plant. The plant was technically compared to a traditional

The plant was technically compared to a traditional methanol production plant using gasified biomass. The project group has decided to focus on large scale plants, as the scale economics favor large scale plants. Therefore, the dimensioning input of the concept 1) plant is 1000 tons wood per day. This is truly a large scale gasification plant; however, in a methanol synthesis context the plant is not particularly large. The SOEC electrolyzer unit is dimensioned by the need of hydrogen to balance the stoichiometric ratio of the methanol synthesis reaction, which will result in 141 MW installed SOEC. The resulting methanol output is 1,050 tons methanol per day. In comparison to a traditional methanol synthesis plant operating on biomass gasification without electrolysis, the plant methanol output is doubled and the methanol production efficiency is boosted from 59 % to 71 %. The total plant efficiency was 81.6 %. The economic analysis revealed that green methanol can indeed be produced at prices very close to the current oil price. In the scenario using the present energy prices and assuming that the critical plant components were readily available, the methanol production was found to be 120 USD/barrel equivalents, which is very close to the current oil price. It can be concluded that the present report has shown that green methanol can indeed be produced at competitive prices and be used as step towards expanding the share of renewable in the energy system and especially in the transportation segment. Therefore, producing methanol from using electrolysis assisted gasification it is possible to produce green methanol from biomass with this ratio: 1,000 t wood = 1,053 t methanol at 120-170 USD/barrel equivalent (1.5 - 2 times the existing oil price - February 2010).
