  • Biofuel Making via Gasification Most Efficient, But Sector Prefers Drop-ins

    BeWhere Sweden webBeWhere Sweden. Illustration by courtesy of Elisabeth Wetterlund, Bio4Energy and the Swedish Knowledge Centre for Renewable Transportation Fuels.In a medium-term perspective until 2030, biomass gasification would be the most cost-efficient option for rolling out advanced biofuel production on a large scale in Sweden, a new research report based on energy system modelling confirms. However, attached analysis of stakeholder advice shows, central actors in the sector have turned their backs on biofuel-making options that require large investments.

    Instead, they appear to favour drop-in fuels made from bio-based hydrocarbons, which properties are similar to those of standard petrol and diesel and can be produced in existing oil refineries. Such advanced drop-ins are being made on a pilot scale by Bio4Energy member RISE Energy Technology Center at Piteå, Sweden and their partner Suncarbon. So-called de-polymerisation of the wood polymer lignin could be a basis for this type of process.

    The report, ending a project called BeWhere - Stakeholder analysis of biofuel production in Sweden, is based on an international energy system model called BeWhere, but which has been adapted to national conditions.

  • Biofuels Report from 2013 Government Investigation Available in Short Form

    Compared with the full report, a few updates had been made regarding the estimate for future sustainable outtake of forestry residues as feedstock for biofuel production, Lundgren said. Moreover, the estimate for annual domestic biofuel production by 2030 had been lowered from 25-35 terawatt hours (TWh) to 22-32 TWh. This was because the estimate for future potential outtake of tree stumps had been reduced, he added.

    The Gothenburg-based f3 Centre published both the report and its summary.

    "f3 took the initiative [for us to draft] the summary because the report we wrote were a couple of hundred pages long. Not something people read in a coffee break, perhaps".

    Both papers are intended to guide researchers and decision-makers working to pave the way for ridding Sweden's transport fleet of its dependence on fossil fuels and meet the country's greenhouse gas reduction targets.

  • Clean-burning Cooking Solutions, Electricity, Being Developed for Africa

    The world needs clean-burning stoves for use in countryside households in third world, the Umeå Renewable Energy Meeting (UREM) 2016heard today. Many such households, for instance in Sub-Saharan Africa, rely on burning of untreated wood or agricultural residues inside the home and in simple appliances with few or no checks on polluting emissions.

Boman leads a cross-disciplinary project in which Bio4Energy researchers from Umeå University and the Swedish University of Agricultural Sciences collaborate with the Stockholm Environment Institute and African non-governmental organisations, of which the World Agroforestry Centre in Kenya, to evaluate current so-called clean-burning cookstoves and develop medium-sized facilities for electricity production in the Kenyan countryside.

  • Clean-burning Cookstoves, Technology for Local Electricity Production to Be Developed for Africa

    CB cookstoves GroupA project for Africa: Christoffer Boman and colleagues will develop a clean-burning cookstove and propose solutions for local electricity production via biomass gasification. Photos by courtesy of Christoffer Boman.Development of clean-burning technology for household cooking and medium-scale electricity production in Sub-Saharan Africa is the focus of a new multiannual project by Bio4Energy researchers in collaboration with African actors, the Swedish Environment Institute (SEI) and the Swedish University of Agricultural Sciences.

    As the researchers acknowledge in an application for funds to the Swedish Research Council Formas, which has now been granted, almost one fifth of the world population still lacks access to electricity, according to the International Energy Agency. Moreover, indoor air pollution caused by biomass burning for cooking and heating either using poor appliances or simply building a fire indoors cause about two million deaths per year in Southeast Asia and Africa.

    While great strides have been made by high-profile initiatives such as the Global Alliance for Clean Cookstoves, "many uncertainties still exist regarding the performance of different cooking solutions… [and] emissions from these systems and the relation to air pollution and health effects need to be better elucidated", according to the project application.
  • Conditioning with Reducing Agents Shown to Raise Yields in Advanced Biofuel Production

    CM slurry AS231115Carlos Martín and Bio4Energy colleagues have developed a one-step biomass conditioning-and-conversion process which could bring cost-efficiency to cellulosic ethanol production. Photo by Bio4Energy.Bio4Energy researchers have invented a process which could bring greater certainty of cost efficiency to industrial biorefineries that choose to base their operations on lignocellulosic input materials such as wood from spruce or pine trees.

    Currently the U.S.A. and Italy are among few countries in the world to host industrial biorefineries for the production of ethanol based on cellulose via the biochemical conversion route using industrial enzymes and yeast. However, these biorefineries mainly use agricultural residue as feedstock in their operations.

    While advanced bio-based production is seen as a great opportunity in several richly forested countries in the boreal belt, industrial operators there are up against a practical problem. A large part of the Canadian, Swedish and Finnish forest resource is made up of coniferous tree species whose woody composition is highly complex and requires harsh treatment before rendering its cellulose, hemicellulose and lignin components in separate parts, which is a requirement in most bio-based production. This harsh pre-treatment means toxic elements are left in the biomass slurry resulting from the process, whose impact must be reduced for efficiency to be achieved in the conversion step to fuels and chemicals.

  • Deepening Ties Among Members Focus of Industrial Network Seminar by SP Processum, Bio4Energy

    SP Processum and Bio4Energy gave a joint seminar for the SP Processum member companies and Bio4Energy's Industrial Network, yesterday at Örnsköldsvik, Sweden. Seventy-five people from industry, business incubators, academia, research institutes, consultancies and regional and national Swedish authorities came, listened to presentations, workshopped and networked. The focus was on deepening and widening the cooperation between the actors in the network, to uphold and strengthen the position of northern Sweden as a leading region for development of biorefinery based on wood or organic waste. 

    Several speakers took the opportunity to reach out, or even to urge, members of northern Sweden's biorefinery business community to dare to take the step and cooperate to develop innovations.

    One said: "If you think the real reason I am here is to market my offer you are right... We are bringing in new technology and infrastructure and I am asking you: 'Shall we dance?'".

  • Discovery of Mechanism behind Organisation of Plant Cell Wall Raises Hopes for Biorefinery Development

    Plant biologists have long tried to come up with a method for making trees produce large amounts of easily extractable biomass for making renewable products such as biofuels and "green" chemicals. Indeed, international conferences such as Lignin 2014 have seen scores or well-respected scientistsbiologists and chemists alikebrood the reasons why successful attempts to increase biomass production have led to the making of sample plants whose stems and branches sag in sad poses or to increased difficulty at the steps of extracting and separating the main components of wood: cellulose, hemicellulose and lignin.

    Whereas most of these attempts were aimed at trying to increase the production of biomass within the plant cell, a team of scientists based in Sweden and the UK came up with the idea to try to lay bare the processes responsible for the organisation of the cells in the plant's secondary cell wall. Thus the focus is no longer on maximising biomass production, but rather on finding out the exact way in which a plant goes about building its cell walls from within and who is responsible for doing what in that process. The researchers found as many as 605 proteins hard at work, performing specific and mostly non-overlapping tasks to control aspects of the cell wall's organisation such as its thickness, homogeneity, cortical position and patterns.

    "We tried to unravel the processes organising the cell. [What we found is that] the cell wall needs to be placed and organised specifically for wood cells to work. We have identified genes or proteins implicated in the control of this mechanism", said This email address is being protected from spambots.

Photo by courtesy of Umeå University.A new professor in Bio4Energy since the start of its second programme period 1 January 2016, environmental chemist This email address is being protected from spambots. You need JavaScript enabled to view it. has started his mandate by winning a prize for having cooperated successfully with a number of organisations. It is awarded by the Faculty of Science and Technology at his home institution, Umeå University (UmU), and will be handed to him at award ceremony 21 May. Two days prior Tysklind will be giving a public lecture entitled Samverkan – avgörande för utveckling av smart miljöteknik.

    Since cooperation across organisations and disciplinary borders is what Bio4Energy is about, and since Tysklind is part of its new research platform Bio4Energy System Analysis and Bioeconomy, which is task is precisely to provide a system's perspective on processes and products that are developed in the cluster, the award is felt to be timely.

    "During many years we have been making an effort to cooperate widely with different organisations in society. Now that one thinks about it they are incredibly many. Lately we are [reaching out specifically to] organisations that promote sustainable development and green technology and environmental technology. It has resulted in [the university's] investing in a new area of research on Green Technology and Environmental Economics", Tysklind said when asked why he thought he had received the prize.
