Between 2014-2020, three different techniques for small-scale electricity production of biomass-based cogeneration have been built and demonstrated in southeastern Sweden as part of the project Small Scale CHP LIFE+. Partners of the project, where the demonstration plants are built, are Emå Dairy in Hultsfred and Ronneby Environment & Technology AB. There is also collaboration with Linnaeus University, Bioenergy Group, Svebio, Swedish District Heating and Energy Agency in order to study the possibilities for small-scale combined heat and power from a systems point of view.
Short summarizing report on the results: Small-scale heat and power - plannable, local, and circular (2020)
Through the demonstration of the pilot plants, this project has been a catalyst for starting a process that now runs on its own. The project has reach all its objectives and resulted in the following:
Read about the specific results and findings per techniques - see links below.
Emå Dairy is a local producer of milk and dairy products in Hultsfred. The plant is owned and run by the farmers themselves. They have a strong local and environmental profile with their slogan "Milk from your area".
They have installed a gasification plant where wood chips are converted into heat and electricity.
Ronneby Miljö & Teknik AB is a municipal corporation, wholly-owned by Ronneby municipality. They manage power, heat, water, sewage, sanitation, fiber optic networks and broadband. Their goal is to combine environmental responsibility with economic efficiency.
They have installed wet steam turbine for electricity production on the existing district heating plant, Sörbyverket.

The company have also installed an ORC (Organic Rankine Cycle) at the district heating plant in Bräkne-Hoby.

Continuation after the project
After the end of the project, the work will continue through:
List of companies that has installed ORC during the project
The following companies has invested in an ORC plant during the project and all have been at the demonstration site for a study visit.
This project will demonstrate different small-scale biomass CHP technologies. The aim is to pave the way for a broader application of biomass CHP technology. The knowledge gained will be disseminated on a regional, national and European level.
The main project objectives are to
• demonstrate the technologies at small-scale biomass-based CHP plants that will be built in in Southeast Sweden;
• promote the use of, and a business model for, small-scale biomass-based CHP technology at the regional, national and Europe level; and
• increase the production of renewable electricity by promoting local small-scale biomass-based electricity production.
Combined Heat and Power (CHP) technologies based on biomass combustion have great potential to reduce CO2 emissions because they use renewable energy sources, such as wood fuels or sawdust. Typical fields of application for biomass CHP plants are wood processing industries, sawmills, district heating systems and industries with a high process heat and cooling demand. Inorder for CHP plants to operate in a way that is economically and ecologically beneficial, both the electricity and the heat produced must be used.
CHP technology is already available on Swedish and European markets. Due to the high installation costs, and a lack of information about its efficiency, the technology is, however, currently not widely used in small-scale plants. Extensive research has been undertaken to illustrate the vast environmental potential of CHP technology but a larger initiative that looks at increasing market application is still needed.
Conference participation 2020
The results of the Life+ project Small Scale CHP was presented for 50 attendees at a webinar arranged by the BIOCOGEN 2030 platform, on July 7th 2020. You can find the recoding of the webinar and the presentations for downloading here:
The aim of the webinar was to give a chance for CHP (co-generation of heat and power) projects and companies to present their CHP solutions and enlarge the network of the BIOCOGEN 2030 platform. The webinar was held as a side event to the European Biomass Conference and Exhibition that was moved to a virtual platform to cope with the COVID 19 emergency.
Small scale CHP Life+ presented at the Central European Biomass Conference
On January 24, experiences from our small-scale chp project were presented at the Central European Biomass Conference in Graz. The conference is held every other year and attracts researchers, entrepreneurs, politicians and suppliers who share a common interest and knowledge in bioenergy. This year, the conference was held between 22 - 24 January 2020 , attracting a total of 1,500 participants.
In addition to disseminating our knowledge of small-scale cogeneration in the southeast Sweden and Sweden in general to those attending the lecture, all conference participants also received information in the form of an abstract from all lectures being presented at the conference, including that of the Energy Agency of southeast Sweden and the Life+ project Small-scale cogeneration from bioenergy.
Attending the conference also provided knowledge of the situation and trends of bioenergy in Europe. Above all, our project manager Daniella Johansson got to meet and talk to suppliers of small-scale gasification technologies that are not yet available on the market in Sweden.
For information on all conferences, see report under Deliverables above.
