Creation of Value Chains for Biochar as Alternative to Fossil Fuels in Industry in New Project

/in /by

A grouping of Bio4Energy experts on systems analysis have won a large grant to map out new value chains for the production of biochar, a type of charcoal, for use in industry or as a carbon sink.

Biocarbon – with the application biochar, which is a form of biomass pre-treated in high temperatures and in a limited-oxygen environment – is being extensively investigated as an alternative to fossil coal in industrial processes, such as in the iron and steel industry.

However, with each major new replacement product comes the need to ascertain that it is sustainable in terms of economics, as well as social and environmental impacts; and that it can form or fit into the context it is in.

In the new project, PhD students will work together to map out a comprehensive scheme for value chains from raw material supply to industrial markets for this renewable technology.

In the new project, three new PhD students will work together to map out a comprehensive scheme for value chains from raw material supply to industrial markets for this renewable technology. They will perform their work from the Bio4Energy partner universities Luleå University of Technology and the Swedish University of Agricultural Sciences (SLU), both located in northern Sweden.

The project is part of a national Graduate School in Energy Systems, funded by the Swedish Energy Agency and coordinated by Linköping University (LiU), Sweden.

In addition to new value chains for production, the project will deliver policy recommendations and create a pool of in depth knowledge about markets, tools for policy-making and technology.

“We are going to develop knowledge about raw material sources for biocarbon and inventory flows of biomass in Sweden”, said David Agar, senior lecturer at SLU.

“We will look at surplus sources in pulp and paper and saw dust, forestry residues…. It doesn’t mean that we have to stick only with the big industries. We could look at recycled products or waste”, Agar said.

When it came to the potential of biocarbon and biochar as an alternative technology to fossil fuels, Agar said that the project would map both potentials and limitations.

“You cannot expect to have exactly the same process. You have to have something to compensate for the high carbon content of fossil fuels. You have to have a very pure carbon source, with good heating properties”, he added.

Carbon source still needed despite electrification

While it is true that there is a sweeping electrification underway, there are still industrial processes that require either a fossil or alternative source of fuel or gas.

”In fossil fuel-free steel production the plan is to use electricity both in the process of direct reduction and in the electric arc furnace”, according to project leader Elisabeth Wetterlund, Luleå University of Technology (LTU).

Direct reduction is the removal of oxygen from iron ore or other iron bearing materials in the solid state, while an electric arc furnace is a type of furnace used in steelmaking to melt and refine steel scrap or other raw materials, transforming them into molten steel.

Professor Wetterlund explained that while both of these processes are powered by renewable electricity, the addition of a fossil or renewable carbon source is still required to complement the hydrogen that is used for the reduction.

“Despite the electrification we still need carbon to produce the kind of steel we want and create appropriate conditions inside the electric arc furnace. This is where biochar comes in, as a replacement for coal and coke-oven coke”, she wrote in reply to questions.

Systems’ Perspective Needed in Societal Transition Research: Course Start

/in /by

The application is open to Bio4Energy’s generic course Systems’ Perspectives on Biomass Resources. It is a training about systems analysis of bio-based technologies, processes and systems.

“You learn to develop a holistic perspective; to see the big picture. This is important for all researchers and not only when it comes to bioenergy, although this is the topic of this course”, said Elisabeth Wetterlund, professor at Luleå University of Technology (LTU), who is new course coordinator.

“You learn to develop a holistic perspective; to see the big picture. This is important for all researchers and not only when it comes to bioenergy, although this is the topic of this course”.

“It is both about learning to apply a systems’ perspective… and learning to put one’s own research into a wider context. This is particularly important when the research is about technology, phenomena or processes related to [societal] transition”, Wetterlund wrote in an e-mail reply to Communications.

Given that Wetterlund is also deputy manager of the research programme part of Bio4Energy, she should know.

Unique benefit that went from shut shop to open

The Systems’ Perspectives training is part of the Bio4Energy Graduate School on the Innovative Use of Biomass. At the beginnings of the research environment, the Graduate School was reserved for its own advanced student – PhDs and postdoctoral fellows.

In 2014, however, the Bio4Enery Board took the decision to open it to advanced students in Sweden and to interested professionals in the biorefinery and bioenergy sector. The reasoning behind it was basically that some things are too precious not to be shared.

“Bio4Energy has a national mission to contribute technology to produce liquid fuels… This is a strategic decision. We will embrace the rest of the country in a first step that is national. In a second step we should strive to build an international graduate school”, LTU vice-chancellor at the time, Johan Sterte, commented.

And so it was. With a growing membership and Bio4Energy establishing itself as a leading research environment—making methods and tools for developing advanced biofuels, “green” chemicals and smart bio-based materials—the decision was made to open the door to advanced students everywhere, so long as they were affiliated with an accredited institution of higher learning.

“You are in a context and together with others who do similar things as yourself; in this case bioenergy, biorefinery and the like… which gives a cross-disciplinary and multi-disciplinary perspective”.

First week of course is on location in northern Sweden

The first week and last day of course will be on location at Luleå in northern Sweden; 11-15 November and 11 March, respectively.

In between those dates, students will need to put time aside for distance learning in the form of online lectures and project work. Wetterlund, for her part, will be assisted in her coordinatorship by a very seasoned systems analysis expert, LTU professor Joakim Lundgren.

The two have taken turns with Robert Lundmark, economics professor at LTU, to teach and lead the course.

“You are in a context and together with others who do similar things as yourself; in this case bioenergy, biorefinery and the like… which gives a cross-disciplinary and multi-disciplinary perspective”, Wetterlund said.

Role of Forests in Reining in Climate Change, Producing Energy

/in /by

When it comes to the role of the forest in a perspective of climate change mitigation and energy production, a full picture including all aspects impacting their use and benefits is required to start to making sense of the “undeniably complex” discussion taking place in the media and politics.

All aspects of the forest as an economic resource, a provider of recreational value and its capacity for carbon sequestration should be considered, according to an academic expert on the matter.

Professor in Economics Robert Lundmark, Luleå University of Technology, tries to do just that, in a new report from independent nonprofit organisation Centre for Business and Policy Studies (SNS), headquartered in Stockholm, Sweden but with a 30-country-strong membership, according to its website.

Centering on the case of Sweden, with its history of forestry and timber exports, Lundmark starts by discussing the economically profit-bearing aspects of forestry. Timber and renewable energy production both bring revenue to an important business sector and prop up the Swedish economy.

He goes onto billing production of bio-based (or “green”) chemicals as having a beneficial social impact; along with forests or forested areas set aside for recreation or tourism activities.

Biodiversity and its protection and the forest’s capacity to act as a carbon sink, are among environmental considerations, he holds.

All these aspects should be included in a total analysis, according to Lundmark; for any estimates of appropriate trade-offs between the different areas to make sense.

“This is existing knowledge put in a different perspective… It is a balancing act to arrive at an optimal utilisation of forests. We need to consider all societal values or we can easily go wrong”.

Role of science, politics, markets

He stresses, however, that the role of science is to provide assessments and that of politics to correct missteps due to market “failure”.

“A functioning market guarantees an efficient allocation of forest resources. That is how it works in the trading of goods and services. The role of politicians is to correct market failures, for instance in cases where forest owners are not paid for preserving all benefits of the forest. That is why we highlight the discussion about internalising the cost of goods and services”.

A quick check of the Oxford Languages gives that to internalise in an economic sense, means to incorporate costs as part of a pricing structure, especially social costs resulting from the manufacture and use of a product.

Forests as a carbon sink

The assessments that scientists do are still important, because any attempts at cutting greenhouse gases must be cost efficient, according to Lundmark.

“We see that compensation would be required for change to be made on a large scale. Today forest owners are not compensated for leaving the trees in the forest” to promote longer rotation periods.

He says that the starting point is to recognise that forests and their trees are a finite resource and one that becomes more and more in demand along with economic growth.

“It is undeniably a complex debate with many dimensions to account for: Forest management, ecology, social and economic aspects and technical aspects. All of them must come into consideration when we estimate benefits and trade-offs”, Lundmark said.

Three-year Project Could Set Steelmaker Well on Way to Hydrogen-based Operations

/in /by

Industry and academia are teaming up to enable a phase out of fossil fuels in Sweden-based steelmaking industry. Steelmaker SSAB will be collaborating with Luleå University of Technology (LTU) and the metal industry’s research institute Swerim.

After many years of preparatory work, and a multitude of projects, nearly SEK50 million (€4.1 million) will be invested over three years by the European Union and the Swedish Agency for Economic and Regional Growth, according to a press release from LTU. The feasibility of using biogenic carbon sources in hydrogen production is already being demonstrated in studies by Bio4Energy scientists and others.

However, the present project could give the industry a decisive push in laying bare an efficient and economically viable path ahead for transitioning from fossil coal to “green” hydrogen, using biocarbon.

“We [want to arrive at] the best way possible to implement biomass into the flow of steelmaking… We have to make an optimal overall process: An optimised value chain as a whole”, said Kentaro Umeki, professor at LTU Energy Technology.

Four Bio4Energy research leaders are involved. Umeki and Fredrik Granberg are experts at thermochemical conversion of biomass, while Joakim Lundgren and Andrea Toffolo will be collaborating with others to assess biomass availability and possibly also where best to localise facilities geographically for its pre-treatment.

“The industry wants to scale up. This is a push from them. They have several years to build a full-scale plant. They are discussing with engineers” about the way in which to go about it, Umeki said.

The overall project is called FINAST, which is the Swedish acronym for Research and Innovation in Norrbotten for Advanced Green Steel Production and Manufacture. It is headed up by professor Jens Hardell at LTU Machine Elements.

“I think that the FINAST project is a fantastic example of Bio4Energy and CH2ESS joining forces”, said professor Lundgren; with reference to LTU’s Centre for Hydrogen Energy Systems Sweden. It has the aim to integrate production, storage and transport of hydrogen in an optimal way and includes process integration in relation to the electrical power system.
