- The European Union aims to increase bioenergy use. Co-firing biomass with coal represents an attractive near-term option for electricity generation from renewable energy sources (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. The total technical potential for RES-E frombiomass co-firing amounts to approximately 50–90 TWh/yr, which requires a biomass supply of approximately 500–900 PJ/yr. The estimated co-firing potential in EU27 amounts to 20–35% of the estimated gap between current RES-E production and the RES-E target for 2010. However, for some member states the national co-firing potential is large enough to fill the national gap. The national biomass supply potential is considerably larger than the estimated biomass demand for co-firing for all member states. About 45% of the estimated biomass demand for co-firing comes from plants located close to the sea or near main navigable rivers and indicates the possibility for biomass import by sea transport. Thus, biomass co-firing has the potential to contribute substantially to the RES-E development in EU27.

- The European Union aims at an enhanced use of bioenergy. Co-firing biomass with coal represents an attractive near-term option for electricity generation from renewable energy sources (RES-E). The purpose with this study is to assess the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plantinfrastructure in the EU27 Member States (MS). The technical potential for RES-E from biomass co-firing amounts toapproximately 50-90 TWh/year, which requires a biomass supply of approximately 500-900 PJ/year. The national biomass supply potential is considerably larger than the estimated biomass demand for each MS. However, actuallymeeting the possible co-firing biomass demand will require a substantial increase compared to the present primaryproduction of biomass in many MS. The implementation of biomass co-firing will be influenced by e.g., the availability and cost of different biomass resources as well as related transport and handling issues, the development of policies and competing options. Longer term, the biomass co-firing potential will be influenced by the development of carbon capture and storage. In the future work the RES-E generation from co-firing will be compared to the RES-E targets for 2010. The possibility for biomass import by sea will also be indicated.

- 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.

Towards Energy Efficient Housing – the importance of local energy planning
- 2009
-
Ingår i: Proceedings of International Forum on Energy Efficiency in Housing, 23-25 November 2009, Vienna, Austria.

Konferensbidrag (refereegranskat)abstract
- A strategy for local energy planning must be in place in order to transform the local energy system and must comprise all relevant sectors and decision makers, i.e. include the residential sector with its relevant stakeholders. Thus, the housing sector cannot be treated inisolation but should rather be part of an analysis which takes a municipal energy systems perspective. This paper reports from an EU IEE (Intelligent Energy Europe) supported work named PATH-TO-RES which develops a methodology to be used as support tool for local energyplanning. The work uses a number of local case studies (Göteborg (SE), Valencia (ES), Dunkerque (FR), Gdansk (PL) and Arnhem and Lochem (NL)) to develop a step-by-stepassessment which can evaluate and define Pathways to renewable and efficient energy systems.A Pathway is a cost efficient way to bridge over from the present energy system to a sustainable system. In short, the proposed methodology starts with a detailed description of the present system (energy infrastructure as well as decision makers and stakeholders) and, based on this, anumber of steps are defined with the aim to serve as check points to ensure that one or more Pathways can be formulated which describe how the local energy system can be transformed to comply with goals and targets.In order to describe the energy systems of the six case studies in a common way, a schematic model called a RES-diagram (RES=Reference Energy System) has been applied, from which the structure (i.e. components, flows and connections) and energy balance of the systems can bedetermined. In the six municipalities studied considerable variation of population, land area and scale and characteristics of the existing energy systems exist. Differences and similarities between the six systems are highlighted and the paper discusses pre-requisites and conditions for municipal energy planning, based on energy systems of the case study regions.

Assessment of the potential for CO2 capture in European heavy industries
- 2009

Konferensbidrag (refereegranskat)abstract
- This study aims to assess the role of CO2 capture and storage (CCS) technologies in reducing CO2 emissions from the European industry sectors. Emphasis is here placed on three branches of industry with promising prospects for CCS; mineral oil refineries, iron and steel, and cement production. A relatively small number (~270) of large installations (>500 000 tCO2/year) dominates emissions from these three branches. Together these installations emit 432 MtCO2/year, 8% of EU’s total greenhouse gas emissions. If realizing the full potential of emerging CO2 capture technologies some 270-330 Mt CO2 emissions could be avoided annually. Further, several regions have been singled out as particularly suitable to facilitate integrated CO2 transport networks. The best matches between sources and sinks are currently found in regions bordering the North Sea.
