  • New Projects to Map Cost of Increasing Carbon 'Efficiency' of Advanced Biofuels

    Bio4EnergyArlanda SE AnnaStrom2020Some of the feedstock that goes into bio-based jet fuel products being developed goes to waste already in the production process. Bio4Energy researchers have set out to find out how much and what can be done about it. Photo by Bio4Energy. researchers are launching the second in a series of projects, to map the extent of the so-called carbon efficiency of advanced biofuels and calculate the cost of efficiency improvements. In this context, carbon efficiency is a measure of the extent to which the carbon in the bio-based starting material, or feedstock, ends up in the final energy product.

    Whereas the first project looks at a number of routes to produce biofuels for road transport, via specific value chains; the second is focussed on bio-based jet fuel technologies and resulting products.

    Biomass gasification employing Fischer–Tropsch technology and alcohols-to-jet, respectively, were two relevant tracks considered in this project in terms of using wood-based feedstock for jet fuel production in the short term, he explained.

  • Opportunity for Pulp Mill Operators to Make Climate-efficient 'Drop-in' Biofuels while Increasing Pulp Production Capacity

Both operations are in Sweden. Photos by courtesy of Per Pixel and Caroline Lundmark, respectively.A new report designed to lay bare the potential for coupling pulp production with biofuel making from pulping residue, shows that there is a double benefit to be had in doing so for pulp mill operators.

    First, production capacity could be increased at existing mills. Second, climate-efficient transport biofuel could be produced at a cost per energy unit that is on a par or better, compared with similar biofuels made from residues from forestry operations.

    The new fuels would be so-called drop-in biofuels, which means that they are functional equivalents of their petroleum fuel counterparts and thus can be directly blended in with these latter at any ratio.

    The researchers' report identifies two main technologies that would put the production cost of the biofuel at 80 euros per megawatt-hour (MWh) or about 65-to-75 euro cents per litre. It is the result of a collaboration project between Bio4Energy systems analysis researchers at the Luleå University of Technology (LTU) in Sweden, companies in the sector and researchers from the RISE Research Institutes of Sweden.
