Real-world experiences of ERS : Best practices from demonstration projects in Sweden and Germany
In: http://urn.kb.se/resolve?urn=urn:nbn:se:ri:diva-48792
Demonstration projects currently underway will test Electric Road Systems (ERS) along public roads and in real-life environments, addressing various legal, political, economic, and efficiency aspects of ERS. Public road tests provide decision makers and investors with a foundation for further investments that would bring ERS to commercial operation. At the time of writing, Sweden and Germany together represent the largest collection of real-world experiences in ERS: The Swedish Transport Administration has funded four demonstration projects along public roads in Sweden, and has also initiated planning of a full-scale ERS pilot. Similarly, in Germany there are two ongoing demonstration projects along public roads and the German federal government is funding the construction of one additional demonstration project. The purpose of this report is to report best practices from demonstrations of ERS technologies along public roads in Sweden, and procurement and the start of ERS demonstration projects in Germany. ; Swedish-German Research Collaboration on Electric Road Systems (CollERS)

Optimal measures in order to reduce total emissions from non-road mobile machinery in a national and economic perspective
In this report future annual emissions amounts of gaseous pollutants, particulate matter (PM10) and noise from the non-road mobile machinery sector in Sweden were estimated. The estimates over future emissions amounts were conducted for each year from 2006 to 2020. Special focus has been taken to the impact of European and national legislations, the age distribution of different types and sizes of machinery and measures to reduce the annual emissions. Besides different measures to reduce emissions, corresponding costs were also estimated. The study comprises fuel consumption and emissions of CO2, carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM), and noise from non-road mobile machinery equipped with diesel engines with a rated engine power of 37 to 560 kW. Non-road mobile machinery for example includes tractors, wheel loaders, excavators, articulate haulers, mobile cranes, combined harvesters, forestry machinery and trucks. The current report was a supplementary study to a report describing a methodology for estimating annual fuel consumption and emissions from the non-road mobile machinery sector in Sweden for year 2006. Inventory data of the year 2006 study was obtained from the Swedish machinery testing institute's machinery inspection operation, statistics of sale returns from trade organisations and the Swedish motor-vehicle register. The number of machinery and annual fuel consumption and emissions amounts for year 2006 is presented in table S1. Besides estimates of annual fuel consumption and emissions amounts, emissions of noise was also derived both at a national level and for a specific construction site. For the case study the results showed that it was possible to reduce the average noise level with more than 3 dB(A) compared with the base scenario just by choosing the machinery fulfilling the strictest noise limits, i.e. Stage II which was mandatory for most machinery from 2006. Other measures simulated included various types of retrofit of noise reduction packages. The specific cost for the different measures to reduce average noise emissions from the specific construction site varied from 4 000 up to more than 500 000 SEK dB-1. For the estimate of future fuel consumption and emissions amounts various simulations were conducted, each with a different measure for reducing the annual amounts. Five main emission reduction measures or programs were studied: - Scrappage program - Alternative fuel program - Voluntary emission regulation program - Retrofit of aftertreatment program - Noise reduction program The impact on engine exhaust gas emissions and noise of the current European emission and noise regulations, Stage I to IV and Stage I to II for emissions and noise respectively were common for all simulations or programs. Besides the impact of European regulations, annual work was set to a fixed value for each type of machinery and year simulated, thus eliminating any potential changes of the state of the market. The result of the baseline scenario "Business as usual" (BAU), i.e. only taking account to the impact of European regulation, is presented in table S2 for four different years Both fuel consumption and emissions of CO2 remains fairly constant as an effect of the assumption that the annual work was set at a fixed value. However, emissions of especially NOx and PM showed a major reduction due to the tighter and tighter regulations. All programs simulated were able to reduce the emissions compared with the BAU scenario with exceptions for emissions of nitrogen oxides, which increased in some of the alternative fuel programs. Both the absolute reduction and cost varied significantly between and within the various programs. Reduction of NOx varied from an accumulated increase in emissions of 25 000 tonne to an accumulated reduction of 22 000 tonne for the studied period from 2006 to 2020. At the same time the accumulated cost for the programs varied from a few hundred million SEK to more than 60 000 million SEK. In table S3, specific reduction cost for each pollutant in SEK kg-1 for eight typical emission reduction programs are presented. The results showed that the most economically favourable alternative for reducing emissions from non-road mobile machinery was the voluntary emissions regulation program, i.e. early introduction of machinery fulfilling coming emission limits. Another important result was that the introduction of alternative fuels as a mean of emissions reduction was associated with rather high costs compared to the actual reduction in emissions. For emissions of nitrogen oxides the specific reduction cost varied from almost 100 SEK kg-1 up to a few hundreds of SEK kg-1 except for the alternative fuel programs, which resulted in a considerable higher cost.

Key Messages on Electric Roads : Executive Summary from the CollERS Project
In: http://urn.kb.se/resolve?urn=urn:nbn:se:ri:diva-52634
Electric road systems (ERS) can reduce greenhouse gas emissions in the transport sector. The market-ready ERS drive systems are characterised by high energy efficiency and low operational costs compared to fossil fuels and biofuels for combustion engines. The introduction of ERS will depend on governmental support, balancing the overall need for GHG-reduction with the business perspectives of the transport market and the energy market. There is an urgent need to establish standards for core components and important interfaces in order to build confidence among potential ERS users. Since ERS will take time to scale up, we should begin to transform the electricity system to meet the demand for ERS while also meeting GHG reduction goals aligned with strong climate policies. There is a need to clarify whether an ERS system is part of the road infrastructure market or the energy market, and to define the role of the public sector in ERS deployment. Since a significant part of long-haul road freight transport is international, ERS deployment will benefit from cross-country cooperation. ; Swedish-German Research Collaboration on Electric Road Systems (CollERS)

Research & Innovation Platform for Electric Road Systems
The Swedish government has prioritized achieving a fossil fuel-independent vehicle fleet by 2030 which will require radical transformation of the transport industry. Electrifying the vehicle fleet forms an important part of this transformation. For light vehicles, electrification using batteries and charging during parking is already well advanced. For city buses, charging at bus stops and bus depots is being developed, but for heavy, long-distance road transport, batteries with enough capacity to provide sufficient range would be too cumbersome and too much time would have to be spent stationary for charging. One solution might be the introduction of electric roads, supplying the moving vehicle with electricity both to power running and for charging. In the longer term, this approach could also be used for light vehicles and buses. The objective of the Research and Innovation Platform for Electric Roads was to enhance Swedish and Nordic research and innovation in this field, this has been done by developing a joint knowledge base through collaboration with research institutions, universities, public authorities, regions, and industries. The work of the Research and Innovation Platform was intended to create clarity concerning the socioeconomic conditions, benefits, and other effects associated with electric roads. We have investigated the benefits from the perspectives of various actors, implementation strategies, operation and maintenance standards, proposed regulatory systems, and factors conducive of the acceptance and development of international collaborative activities. The project commenced in the autumn of 2016 and the main research continued until December 2019, the work during year 2020 has been focused on knowledge spread and coordination with the Swedish-Germany research collaboration on ERS (CollERS). The results of the Research and Innovation Platform have been disseminated through information meetings, seminars, and four annual international conferences. Reports have been published in the participating partners' ordinary publication series and on www.electricroads.org. The project was funded by Strategic Vehicle Research and Innovation (FFI) and the Swedish Transport Administration.
