"Kol och kärnkraft behövs för att avvärja klimathotet"
Växande hot. Utsläppen av koldioxid fortsätter att öka globalt. Det behövs därför ett kraftfullt politiskt initiativ och ett radikalt nytänkande för att avvärja klimathotet. Svensk och europeisk energidebatt och -politik baseras fortfarande på att vi kan välja mellan olika tekniker och åtgärder. Detta är fel. Om vi ska ha en chans att klara utsläppsminskningarna behövs samtliga energislag inklusive kärnkraft och kolkraftverk med teknik för avskiljning och lagring av koldioxid, skriver professor Filip Johnsson.

Path dependence in the legal system:
implication for the development of wind power
The research concerning of the role of the legal system in the transformation of the energy system is continued at the University of Luleå. The aim of the next step is to analyse the legal implementation of wind power in Sweden on the basis of presumed path dependence.

An overview of the carbon strategies of ten of Europe's largest energy companies
A study of the 'carbon strategies' of ten of Europe's largest energy companies reveal that the large European
energy producers are in the process of implementing strategies that reflect the need for less-carbon-intensive
and more sustainable energy production.

Non fossil emission clusters are crucial for CCS within the pulp and paper industry
With increasing CO2 prices, CCS could become a cost effective option for reducing CO2 emissions in pulp and paper mills. If all mills with annual emissions above 0.1 Mt CO2 would implement CCS, the total capture potential would be 80 Mt/yr. The capture potential would still be 50 Mt/yr if only including larger mills in capture clusters based on fossil as well as biogenic emissions. However, if restricting the focus to fossil emission capture clusters, the potential for capture is low, only about 8 Mt/yr. >> Read more
Investment analysis of cross-border interconnections of European Power System
With the DC-Power Flow model, grid bottlenecks for a future electricity-production system can be identified and different grid reinforcement options can be evaluated. Analysis of a business as usual case indicates several potential bottlenecks in the European transmission system, unless investments in the grid are undertaken. Profitable grid reinforcement options to avoid the bottlenecks are also identified . >> Read more
Pathway results presented at a conference in Tallinn
Erik Axelsson and Anders Sandoff's paper about bioenergy combines was presented at the 12th International Symposium on District Heating and Cooling conference in Tallinn 5-7 September. This paper evaluates the prospects of bioenergy combines in district heating.
Urban Persson and Sven Werner's contribution about effective width for district heating pipe lengths in city areas was also presented at this conference. Download the papers below!

Waste can contribute to sustainablility targets
According to current EU Directives, European waste management is required to undergo extensive changes. For instance, renewable waste fractions to landfill are to be reduced. Instead of being put on landfill, waste can be utilized, e.g. as fuel. This has a double greenhouse gas reducing effect, contributing significantly to the EU202020 targets.>> Read more
EU can become self sufficient in coal and gas
Looking at a longer perspective, indigenous fossil fuel production within EU27 will most likely continue to decrease. However, with concerted efforts to maximize production, the production decrease can be partly mitigated. This, combined with decreased fuel demand in the analysed pathways, implies that EU can become self sufficient in coal and, close to so, in gas.>> Read more
Legal preconditions are crucial for wind power expansion
The design of legal and administrative systems is crucial for the development of wind power. In Swedish law there are several counteracting factors and other barriers for wind power expansion. Less permits and strengthened state controlled planning, as in some other counties, could facilitate expansion.>> Read more
Mr Gas and little miss Biomass
- a hot Spanish love story
The efficient use of biomass is an important means in attaining a sustainable energy system. Erik Pihl and Stefan Heyne have investigated the possibilities to integrate biomass power generation with the existing power generation system. Their work indicates the potential for biomass power generation if co-located with natural-gas fired CCGT plants. >> Read more
Path dependency in focus
In a comparative study similarities and differences in cases of market based and policy/government based infrastructure are analysed. We will look at two cases of planning and building of technical infrastructure that are differently regulated and organized; rail way lines and wind farms respectively. >> Read more
Interreg Project: Pathways for CCS in the Kattegatt/Skagerrak region
The Interreg Project with the aim to investigate the opportunities for CCS in the Skagerrak region is now launched. Chalmers is responsible for work package 3 covering the political, judicial and economical perspectives of CCS in the area. >> Read more

The competitiveness of District Heating
- consequenses of energy savings in the domestic sector
Researchers from Halmstad University show that the competitiveness of district heating only decreases moderately with 20% energy savings in the domestic sector but considerabely with 50% energy savings. >> Read more
Emission standards can cause the EU ETS to fail
It is possible that there will come emissions performance standards (EPS), setting a roof for the CO2 emissions (CO2/kWhel) from the power production. >> Read more
Great potential for CCS in the industrial sector
In the Pathway industrial group the potential for carbon capture and storage in the industrial sector is being assessed. The first results show that about 50% of all CO2 emissions from the industrial part of EU ETS can be captured with capture cost up to 45 €/tonne CO2.

Are we prepared for a substantial change of the energy system?
A substainable energy and climate policy needs technical advances, but these are not sufficient. The policy needs a legal system clearly supporting the implementation. This situation does not exist in our countries today. >> Read more

Political springtime for nuclear energy? But what about the law?
The political message in 2009 is to rely upon nuclear energy for many years to come. Licences have already been issued to increase the production capacity in existing reactors and it is not unlikely that new reactors will be constructed, foremost to replace outdated existing ones. This policy has several legal implications. >> Read more
Intensive cultivation of forests
A future scenario in Sweden is a significantly increased intensive cultivation of different kinds of forests. The biomass produced may be used as fuel instead of e.g. oil and coal. What are the legal constraints to such cultivation? Should we relieve existing legal restrictions in order to facilitate implementation of a new energy and climate policy? >> Read more

Modelling the European electricity
Four models are used to analyze the long-term development of the European electricity system in the Pathways project. Due to several reasons it is in this case more efficient to use four models each addressing specific issues rather than noe "super" model trying to incorporate "as much as possible". >> Read more
