    Energy end-use and efficiency potentials among Swedish industrial small and medium-sized enterprises - A dataset analysis from the national energy audit program2018In: Renewable & sustainable energy reviews, ISSN 1364-0321, E-ISSN 1879-0690, Vol. 93, p. 165-177Article, review/survey (Refereed)
    Abstract [en]

    Improving energy efficiency in industry is recognized as one of the most vital activities for the mitigation of climate change. Consequently, policy initiatives from governments addressing both energy-intensive and small and medium-sized industry have been enacted. In this paper, the energy end-use and the energy efficiency potential among industrial small and medium-sized companies participating in the Swedish Energy Audit Program are reviewed. The three manufacturing industries of wood and cork, food products and metal products (excluding machinery and equipment) are studied. A unique categorization of their production processes energy end-use is presented, the results of which show that the amount of energy used in various categories of production processes differ between these industries. This applies to support processes as well, highlighting the problem of generalizing results without available bottom-up energy end-use data. In addition, a calculation of conservation supply curves for measures related to production processes is presented, showing that there still remains energy saving potential among companies participating in the Swedish Energy Audit Program. However, relevant data in the database used from the Swedish Energy Audit Program is lacking which limits the conclusions that can be drawn from the conservation supply curves. This study highlights the need to develop energy policy programs delivering high-quality data. This paper contributes to a further understanding of the intricate matters of industrial energy end-use and energy efficiency measures.

    Energy savings and greenhouse gas mitigation potential in the Swedish wood industry2019In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 187, article id 115919Article in journal (Refereed)
    Abstract [en]

    Improving energy efficiency in industry is recognized as one of the most crucial actions for mitigating climate change. The lack of knowledge regarding energy end-use makes it difficult for companies to know in which processes the highest energy efficiency potential is located. Using a case study design, the paper provides a taxonomy for energy end-use and greenhouse gas (GHG) emissions on a process and energy carrier level. It can be seen that drying of wood is the largest energy using and GHG emitting process in the studied companies. The paper also investigates applied and potentially viable energy key performance indicators (KPIs). Suggestions for improving energy KPIs within the wood industry include separating figures for different wood varieties and different end-products and distinguishing between different drying kiln technologies. Finally, the paper presents the major energy saving and carbon mitigating measures by constructing conservation supply curves and marginal abatement cost curves. The energy saving potential found in the studied companies indicates that significant improvements might be achieved throughout the Swedish wood industry. Even though the scope of this paper is the Swedish wood industry, several of the findings are likely to be relevant in other countries with a prominent wood industry.

    Drivers, barriers and success factors for energy management in the Swedish pulp and paper industry2019In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 223, p. 67-82Article in journal (Refereed)
    Abstract [en]

    Research has revealed the existence of an energy-efficiency gap – the difference between optimal and actual energy end-use, suggesting that energy efficiency can be improved. Energy management (EnM) is a means for improving industrial energy efficiency. However, due to various barriers, the full potential of EnM is not realised. Several studies have addressed drivers and barriers to energy efficiency but few to EnM. This study aims to identify EnM practices, the most important perceived drivers and barriers for EnM, and relations among them in the energy-intensive Swedish pulp and paper industry (PPI), which has the longest experience internationally of practising EnM systems, and has worked according to the standards since 2004. Our results show that, altogether, the PPI works regularly and continuously with EnM, with a clear division of responsibilities. The highest maturity for EnM practices was for energy policy, followed by organization, investments, and performance measurement. The study also shows that communication between middle management and operations personnel has potential for improvement. The most important categories of drivers were economic, whereas for barriers they were organizational. Nevertheless, knowledge-related barriers and drivers were amongst the most important, suggesting that the absorptive capacity for energy issues could be improved.

    Energy management in Swedish pulp and paper industry: benchmarking and non-energy benefits2018Conference paper (Refereed)
    Abstract [en]

    Manufacturing industry has a large energy efficiency potential, yet to be utilized, known as the energy efficiency gap. This gap exists due to barriers that hinder industrial companies from making energy efficiency investments. Research also shows that the gap is even larger if energy management practices are included as well. One type of energy management practice for industrial companies is energy performance benchmarking, which deals with several organisational applications. For example, energy performance benchmarking can be used to compare a company’s degree of energy efficiency to its peers. A benchmarking approach can also be adopted on different levels of aggregation, including sector, site, and process level. Furthermore, continuous work with energy management also entails additional benefits beyond the energy effects, known as non-energy benefits. In an energy management context, these benefits might for instance be organisational or informational in nature. The aim of this paper is to study these aspects of energy management – benchmarking and non-energy benefits – within the Swedish pulp and paper industry.

    These aspects of energy management have not, to the authors’ knowledge, been extensively investigated. The adopted method for data collection is a mixed method approach, where a questionnaire was sent to all operating pulp and paper mills in Sweden, and semi-structured interviews were carried out at six mills. The findings in this study show that the most common benchmarking method in the Swedish pulp and paper mills is external benchmarking within a company group. The benchmarking method with the highest perceived value for a mill’s energy management, however, is historical benchmarking of energy use. Furthermore, the pulp and paper mills have perceived a number of non-energy benefits from energy management practices, where top management’s interest in energy efficiency issues increasing more than expected was perceived as the most substantial.
