Linking process integration and energy market scenarios to evaluate biomass saving measures at pulp mills
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2004

This paper presents a methodology to analyse total system costs and CO2 emission consequences for energy efficiency measures at a process plant when biofuels are saved and sold on the energy market. Process integration measures and energy market scenarios are linked for a rational treatment of for example electricity prices, fuel prices, and policy instruments. Promising process integration measures are analysed using a set of energy scenarios in order to cover different possible future developments. For each scenario marginal biomass utilisation and marginal electricity production is identified, assuming that a process integration measure is a distortion to the baseline defined by each scenario. The scenarios used emanate from a large energy market model covering the Nordic countries from 1995 to 2050. The methodology is applied to a pulp plant located in Sweden. Results show that there are several options to find in-house process integration measures at pulp mills to increase biofuel market supply at competitive costs. Even so, CO2 emission consequences for the measures are very dependent on scenario used. In some cases CO2 emissions may even increase.
