Active Solar Energy Storage (ASES) is an active heat storage system for low- and zero-energy buildings. It is a unique energy system that utilizes, seasonal stores and recycles the sun's energy for heating and domestic hot water in buildings during the winter.
The heating and cooling system of the hospital in Kristianstad uses energy from an aquifer in order to heat the hospital in winter and cool it in summer. This is a unique clean energy solution that uses “free energy” in a creative way. The solution was developed by Region Skåne in cooperation with the company Malmberg Water.
The municipalty of Skellefteå collect waste from homes and workplaces and produces there own biogasfuell for use in the municipality cars and in the public buses. The Biogas plant turns organic waste into biogas. Food bio waste from homes and workplaces is selected and placed in the brown waste container so that it can be taken to the biogas plant. The fuel that comes from this plant is used in the municipality cars and in the public buses, but it can also be bought by anyone whose car can take such fuel.
In a unique project, Fortum provides Nynas AB refinery in Nynäshamn with process steam, coming from the biofuel-powered cogeneration plant. In return, Fortum is given access to the surplus heat from the refinery, which they will use to heat Nynäshamn’s municipality. This project will result in reduced emissions of carbon dioxide, with nearly 100 000 t / year.
The district heating plant in Bålsta supplies Håbo municipality with environmentally-friendly heat and hot water. The plant consists of three boilers: a wood chip boiler, a pellet boiler and an oil-fired boiler, which together represent 80% of the plants total energy production. The remaining 20% are taken from a adjucent gypsum factory, whose waste heat is led to the boiler through pipes.
Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.

Gothenburg is determined to be one of the world’s most progressive cities in tackling climate change.
The Climate Program gathers the long-term climate work of Gothenburg: the municipal organisation, commercial and industrial sector and inhabitants. One important goal is to reduce greenhouse gas emissions. In 2012, Gothenburg released more than 8 tonnes per capita. Our goal is to reduce emissions to 3.5 tonnes by 2035 and 1.9 tonnes by 2050.
Hedensbyn was Skellefteå Kraft’s first bioenergy combine when it started operations in 1996 and has been a world leader in the development of modern bioenergy technology ever since. The facility consists of a Combined Heat and Power plant generating district heating and green electricity, as well as a biopellet factory.
CHP plant produces district heating for Kalmar city and suburbs as well as renewable electricity equivalent to 1/3 of Kalmar's electricity needs. The plant is fed with biomass from the forest in the form of wood chips, bark and residues from forestry and wood industries as well as a small amount of peat. CHP plant produces district heating for Kalmar city and suburbs as well as renewable electricity equivalent to 1/3 of Kalmar's electricity needs.
Händelöverket is today owned by E.ON Värme AB. The first boiler was commissioned in 1982 and the site has since been extended and refurbished many times in order to always exhibit the latest environmental performance, the latest boiler was commissioned in 2011. Händelöverket is one of Sweden’s biggest and most modern power plants and it supplies Norrköping and Söderköping with heat and power and it also supplies process steam to Agroetanol for the production of ethanol. Händelöverket is an efficient system that utilizes 90% of the fuel’s energy. The fuel consists of 95% waste and biomass.
Derelict industrial premises from the era of shipyards have been transformed into an exciting mix of modern housing and renovated dockside buildings.
The reconstruction of Eriksberg was made with the environment in focus. One interesting feature is the underground waste collection system. Eriksberg is one of the first areas in the world using several fractions. It was started already in 1993 and is still expanding. When Eriksberg is complete the automated waste collections system will handle waste (food-, paper- and residual waste) for over 5000 apartments.
The Filborna plant is a waste-to-energy plant which combusts sorted waste from the nearby region. It supplies approximately 40 percent of Helsingborg’s heating demand. The plant features a state-of-the art, combined flue gas cleaning and condensation system to ensure high efficiency whilst meeting stringent emission requirements. The plant was commissioned in 2013 and is run by Öresundskraft, the municipality of Helsingborg’s wholly owned energy company. It has a 70 MW boiler and an annual incineration limit of 160,000 tonnes of refuse-derived fuel (RDF).
A small recycling centre in Huddinge municipality produces biogas using organic waste, which is unique in the Stockholm region. Despite the fact that only a few tons of biogas is produced every year, the plant brings important knowledge for future projects.
When opened in spring 2007, the Gasendal plant, was the largest biogas upgrading facility in the world.
The plant receives biogas from Gryaab, a local wastewater treatment plant, and upgrades it to natural gas quality. The gas, which is injected into the natural gas grid, is used primarily as vehicle fuel in accordance with the green gas principle, in a way similar to the trade in green electricity. By replacing petrol with biogas in vehicles, carbon dioxide emissions is cut by up to 15,000 tons per year.
