Researchers In Denmark have been looking hard at the amount of biomass that will be available for biofuels after 2030 is going to become tight. This is what they say in a peer-reviewed paper in Environment Science Technology, produced by the American Chemical Society.
We show that toward 2030, regardless of whether a globalor European perspective is applied, the amount of biomass, which canbecome available for bioethanol or other energy uses, will bephysically and economically constrained. This implies that use ofbiomass or land for bioethanol production will most likely happen atthe expense of alternative uses. In this perspective, we show that forthe case of a new advanced bioethanol technology, in terms of reducinggreenhouse emissions and fossil fuel dependency, more is lost thangained when prioritizing biomass or land for bioethanol. Technologypathways involving heat and power production and/or biogas, natural gasor electricity for transport are advantageous.
There’s more, but you have to subscribe. The bit that interests me is the parts about heat and power production, that is static power generation. I guess there could be real benefits in this area because potentailly at least you could build power plants in the middle of agricultural areas. There would be transmission losses, but this would probably be less than the energy needed to transport liquid fuels around.
