Sekab, the largest ethanol producer in Sweden, currently has a pilot plant to produce cellulosic ethanol. “We plan to have a development plant that is 40 to 50 times larger up and running in 2010” says Per Carstedt, Sekab’s Chief Executive officer in an interview with Ethanol Statistics. “We think that will take 2 to 3 years to operate and to build a new one, than you’ll have cost-competitive technology probably around 2013-2014.”
“But having technology is one thing, applying it large scale is another. For that you need a balance in demand and specifically in supply of biomass, since you cannot produce in a sustainable manner if you use more than the annual growth of biomass.”
Mr. Carstedt explains why supply and demand of biomass is ultimately more important than the technological issue. “As oil reserves are depleting the question becomes, how does it compare to other renewable energies, which depends on where we are in 10 years. Will we still have the capacity to expand the production from grains? If you don’t, what else do you have except cellulose? And at that point, you are only competing with yourself. At that stage, cost-competitive depends on the price of biomass, making feedstock development key. Subsequently, the question than turns to volumes. Are the residuals sufficient, or do we have to look to other fractions? This is a very step wise development.”
