Tidskriftsartikel (refereegranskat)abstract
- Presently, the European Union (EU) is promoting bioenergy. The aim of this paper is to study the prospects for using domestic biomass resources in Europe and specifically to investigate whether different policy objectives underlying the promotion of bioenergy (cost-effective climate change mitigation, employment creation and reduced dependency on imported fuels) agree on which bioenergy options that should be used. We model bioenergy use from a cost-effectiveness perspective with a linear regionalized energy- andtransport-system model and perform supplementary analysis. It is found that the different policy objectives do not agree on the order of priority among bioenergy options. Maximizing climate benefits cost-effectively is in conflict with maximizing employment creation. The former perspective proposes the use of lignocellulosic biomass in the stationary sector, while the latter requires biofuels for transport based on traditional agricultural crops. Further, from a security-of-supply perspective, the appeal of a given bioenergy option depends on how oil and gas import dependencies are weighed relative to each other. Consequently, there are tradeoffs that need to be addressed by policymakers promoting the use of bioenergy. Also, the importance of bioenergy in relation to employment creation and fuel import dependency reduction needs to be further addressed.

Biomassa - en knapp resurs i globalt perspektiv
- 2007
-
Ingår i: Bioenergi - till vad och hur mycket?. ; :Formas Fokuserar, s. 19-32

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Idag använder vi ungefär tio gånger mer fossil energi än bioenergi i världen. Nu ökar användningen av bioenergi kraftigt. Men globalt sett finns det inte tillräckligt med bioenergi för att ersätta de fossila bränslena, skriver tre forskare på Chalmers. Hur ska vi använda de knappa resurserna på bästa sätt? Och hur ska vi kunna begränsa de negativa effekter som ökad efterfrågan på bioenergi kan få? Det handlar bland annat om exploatering av värdefulla ekosystem som regnskogar.

Expanding sugarcane ethanol production in Brazil - Socioeconomic and climate effects of expanding sugarcane ethanol production in the Pontal do Paranapanema region (State of São Paulo, Brazil)

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents results from a study of socioeconomic and climate effects connected to a sugarcane expansion scenario in the Pontal do Paranapanema region, São Paulo state, Brazil. Sugarcane production is expected to grow in the São Paulo state. Pontal do Paranapanema is the only region in the state where a large scale sugarcane expansion can take place and there is a concern that without guidelines the expansion might affect income growth in a negative way. A scenario where the settlers in the region gain from the sugarcane expansion was modelled. The models showed that it is possible to introduce sugarcane in the region with positive effects both on income growth and greenhouse gas emissions.

Co-generation of biofuels for transportation and heat for district heating systems – an assessment of the national possibilities in the EU

- Biomass gasification with subsequent synthesis to liquid or gaseous biofuels generates heat possible to use in district heating (DH) systems. The purpose here is to estimate the heat sink capacity of DH systems in the individual EU nations and assess the possibilities for biomass-gasification-based co-generation of synthetic biofuels for transportation and heat (CBH) for DH systems in the EU countries. The possibilities are assessed (i) assuming different levels of competiveness relative to other heat supply options of CBH corresponding to the EU target for renewable energy for transportation for 2020 and (ii) assuming that the potential expansion of the DH systems by 2020 is met with CBH. In general, the size of the DH heat sinks represented by the existing national aggregated DH systems can accommodate CBH at a scale that is significant compared to the 2020 renewable transportation target. The possibilities for CBH also depend on its cost-competitiveness compared to, e.g., fossil-fuel-based CHP. The possible expansion of the DH systems by 2020 represents an important opportunity for CBH and is also influenced by the potential increase in the use of other heat supply options, such as, industrial waste heat, waste incineration, and CHP.

On the possibility for cogeneration of biofuels for transport and heat for district heating systems in EU25

Konferensbidrag (refereegranskat)abstract
- 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.

- This study investigated the effects of rosuvastatin on plaque progression and in vivo coronary artery function in apolipoprotein E-knockout (ApoE-KO) mice, using noninvasive high-resolution ultrasound techniques. Eight-week-old male ApoE-KO mice ( n = 20) were fed a high-fat diet with or without rosuvastatin (10 μmol·kg−1·day−1) for 16 wk. When compared with control, rosuvastatin reduced total cholesterol levels ( P < 0.05) and caused significant retardation of lesion progression in the brachiocephalic artery, as visualized in vivo using an ultrasound biomicroscope ( P < 0.05). Histological analysis confirmed the reduction of brachiocephalic atherosclerosis and also revealed an increase in collagen content in the statin-treated group ( P < 0.05). Coronary volumetric flow was measured by simultaneous recording of Doppler velocity signals and left coronary artery morphology before and during adenosine infusion. The hyperemic flow in response to adenosine was significantly greater in left coronary artery following 16 wk of rosuvastatin treatment ( P < 0.001), whereas the baseline flow was similar in both groups. In conclusion, rosuvastatin reduced brachiocephalic artery atherosclerotic plaques in ApoE-KO mice. Coronary artery function assessed using recently developed in vivo ultrasound-based protocols, also improved.

Co-firing biomass with coal for electricity generation—An assessment of the potential in EU27
- 2009
-
Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215. ; 37:4, s. 1444-1455

Tidskriftsartikel (refereegranskat)abstract
- 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.
