On the possibility for co-generation of biofuels for transport and heat for district heating systems in EU25

Andrea Egeskog Julia Hansson Göran Berndes S. Werner

The gasification of biomass with subsequent conversion to liquid biofuels (BtL) results in considerable amounts of surplus heat. Some of this heat could be used in district heating (DH) systems. The aim of this study is to assess the potential for integration of BtL plants with the EU’s DH systems. The major parts of the DH systems are presently based on the use of fossil fuels. The fossil fuels are also dominating the EU transport sector. Thus, integration of BtL plants with the EU’s DH systems could contribute to EU goals of increasing the use of biomass for both heat and transport. The heat sink represented by the aggregated national DH systems is large enough to produce substantial amounts of biofuels for transport by co-generation. However, the potential contribution of the assessed option for meeting the EU target for biofuels for transport for 2020 is highly dependent on BtL plant configuration and competitiveness vs. other heat sources in the DH systems, e.g., CHP. It is found that integration of BtL with DH offers a substantial opportunity, but the attractiveness and possible impacts of expanding such systems need to be further analyzed.

The potential for biomass co-firing with coal in EU27

Julia Hansson Göran Berndes Filip Johnsson Jan Kjärstad

The European Union (EU) aims to increase the use of bioenergy. An increased production of electricity from renewable energy sources (RES-E) is also being promoted within the EU. Biomass co-firing with coal represents an attractive near-term option for increasing the production of RES-E. This study assesses the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plant infrastructure in the EU27 Member States (MS) and relates the potential to the national EU targets for RES-E by 2010. The possible contribution of RES-E from biomass co-firing to the RES-E target for 2010 for EU27 as a whole (expressed in absolute numbers) is about 10%. However, the contribution from the estimated co-firing potential to the gap between current RES-E levels and the RES-E target for 2010 is about 20-33% for EU27 (depending on assumptions made). For some MS the potential contribution is large enough to fill the gap. Biomass co-firing with coal has the potential to play an important role when increasing the amount of RES-E in EU27. However, considering how little time remains, it is unlikely that co-firing can actually make a considerable contribution to the 2010 RES-E targets.

On the role of forests and the forest sector for climate change mitigation in Sweden

GCB Bioenergy (2022)

Hans Petersson David Ellison Alex Appiah Mensah Göran Berndes Gustaf Egnell

Abstract We analyse the short‐ and long‐term consequences for atmospheric greenhouse gas (GHG) concentrations of forest management strategies and forest product uses in Sweden by comparing the modelled consequences of forest resource use vs. increased conservation at different levels of GHG savings from carbon sequestration and product substitution with bioenergy and other forest products. Increased forest set‐asides for conservation resulted in larger GHG reductions only in the short term and only when substitution effects were low. In all other cases, forest use was more beneficial. In all scenarios, annual carbon dioxide (CO 2 ) sequestration rates declined in conservation forests as they mature, eventually approaching a steady state. Forest set‐asides are thus associated with increasing opportunity costs corresponding to foregone wood production and associated mitigation losses. Substitution and sequestration rates under all other forest management strategies rise, providing support for sustained harvest and cumulative mitigation gains. The impact of increased fertilization was everywhere beneficial to the climate and surpassed the mitigation potential of the other scenarios. Climate change can have large—positive or negative—influence on outcomes. Despite uncertainties, the results indicate potentially large benefits from forest use for wood production. These benefits, however, are not clearly linked with forestry in UNFCCC reporting , and the European Union's Land Use, Land‐Use Change and Forestry carbon accounting , framework may even prevent their full realization. These reporting and accounting frameworks may further have the consequence of encouraging land set‐asides and reduced forest use at the expense of future biomass production. Further, carbon leakage and resulting biodiversity impacts due to increased use of more GHG‐intensive products, including imported products associated with deforestation and land degradation, are inadequately assessed. Considerable opportunity to better mobilize the climate change mitigation potential of Swedish forests therefore remains.

Bioenergy for climate change mitigation: Scale and sustainability

GCB Bioenergy (2021)

Katherine Calvin Annette Cowie Göran Berndes Almut Arneth Francesco Cherubini

Abstract Many global climate change mitigation pathways presented in IPCC assessment reports rely heavily on the deployment of bioenergy, often used in conjunction with carbon capture and storage. We review the literature on bioenergy use for climate change mitigation, including studies that use top‐down integrated assessment models or bottom‐up modelling, and studies that do not rely on modelling. We summarize the state of knowledge concerning potential co‐benefits and adverse side effects of bioenergy systems and discuss limitations of modelling studies used to analyse consequences of bioenergy expansion. The implications of bioenergy supply on mitigation and other sustainability criteria are context dependent and influenced by feedstock, management regime, climatic region, scale of deployment and how bioenergy alters energy systems and land use. Depending on previous land use, widespread deployment of monoculture plantations may contribute to mitigation but can cause negative impacts across a range of other sustainability criteria. Strategic integration of new biomass supply systems into existing agriculture and forest landscapes may result in less mitigation but can contribute positively to other sustainability objectives. There is considerable variation in evaluations of how sustainability challenges evolve as the scale of bioenergy deployment increases, due to limitations of existing models, and uncertainty over the future context with respect to the many variables that influence alternative uses of biomass and land. Integrative policies, coordinated institutions and improved governance mechanisms to enhance co‐benefits and minimize adverse side effects can reduce the risks of large‐scale deployment of bioenergy. Further, conservation and efficiency measures for energy, land and biomass can support greater flexibility in achieving climate change mitigation and adaptation.
