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.
Arlanda Airport has managed to reduce its emissions of carbon dioxide with 50 %. A strong contributing factor to the reduced emissions has been the investment in geo energy, which is taken from an underground aquifer.
The biofuelled CHP (Combined Heat & Power) plant is one of Göteborg Energi’s most important heat production plants. It also holds the control room for the entire district heating system of the city.
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.
Braås heat plant, operated by Väsjö Energi AB, produces about 17 GWh per year and supports 113 customers.
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.
Nitrous oxide is used during 80 per cent of childbirths. This gas is a green-house gas 310 times stronger than carbon-dioxide and one kilogram that is emitted into the atmosphere is equivalent to 1500 kilometres of driving a car. Region Skåne, the regional health care management organization of southern Sweden has installed equipment from the company Nordic Gas Cleaning for separating the nitrous oxide into oxygen and nitrogen at all of its five hospitals with birth clinics. This has not only reduced emissions by 99 per cent.
Fittjaverket produces heat by firing wood powder. Wood powder is a by-product from forestry industry and the incineration of this product entails no additional input of carbon dioxide to the atmosphere
Dåva CHP is one of the world's most energy efficient and environmentally friendly plants with waste as its main fuel. Here we produce district heating and electricity from sorted waste and residues from the forest industry.
