Abstract
The purpose of this study is to describe possible benefits from coproducing methanol and electric power based on biofuels compared to separate production of methanol and electric power/district heat respectively. The aim is to describe the order of preference between the studied process alternatives and its sensitivity with respect to changes in e.g. fuel prices or interest rates. The conclusions are valid for the studied plant size, 400 MW biofuel capacity, which was chosen in order to get base material from previous studies for the calculations. Coproduction of methanol, electric power and district heat, utilizing a methanol synthesis and a combined cycle connected in series, gives slightly lower production costs for methanol and electric power than separate production of methanol/heat and electric power/heat respectively. This is the case when the methanol prices and the electric power prices are nearly the same as the production costs for separate plants. Examples of production costs are a little less than 0.3 SEK/kWh methanol and a little less than 0.4 SEK/kWh electric power when assuming 0.22 SEK/kWh as revenues for district heat, 0.12 SEK/kWh as costs for biofuel, 5 % real rate of interest and 25 years of depreciation.

Electric power prices with seasonal variations and with a high power price during the winter are beneficial for the economy of a plant producing electric power during the winter and methanol during the summer, especially if biofuels can be bought for a lower price during the summer period. The absolute production cost levels are especially sensitive to changes of the biofuel prices but also to changes of the capital costs and the costs of operation and maintenance. When assuming e.g. 0.09 SEK/kWh for the biofuel, methanol can be produced for 0.23 SEK/kWh and electricity for 0.32 SEK/kWh. (7 refs., 7 figs., 10 tabs.).}
