Earlier work has shown that capturing CO2 from pulp mills can be a cost effective way of reducing mill CO2 emissions. In this paper it is investigated if the cost efficiency is improved if one uses a BIGCC with fuel production or a heat pump to supply the extra energy needed for the capture process. Heat pump can be interesting alternative for CO2 capture in pulp mills and the evaluation shows results at the same levels as the most cost efficient alternatives in the previous studies. The study also shows that it is better to produce the fuel in stand-alone plants and use the waste heat for electricity production. Another conclusion is that with high CO2 prices CO2 capture can be a very lucrative investment.
