Cogeneration

Technology Type Group:
Definition:
Cogeneration power plants produce electricity but do not waste the heat this process creates. The heat is used for district heating or other purposes, and thus the overall efficiency is improved. For example could the efficiency to produce electricity be just 20%, and the overall efficiency after heat extraction could reach be 85% for a cogeneration plant. It has to be considered that there is not always use for heat.

Cogeneration

  • District Heating Moskogen - Secures heat supply with reliable delivery and low environmental impact

    Type: 
    Product
    Objective:
    Technology:

    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.

  • Sandviksverket combined power and heating plant

    Type: 
    Product
    Objective:

    Sandviksverket in Växjo is a combined power and heating plant, producing heat to the city’s district heating system and power to the electricity market
    Supply of green energy to the city of Växjö

    The plant is 98 percent fuelled with bark, shavings, wood chips and a small amount peat. Consequently its energy production has very little environmental impact. In fact emissions of carbon dioxide are reduced by 249,000 metric tons annually by leaving out the fossil fuels.

  • Turning Waste into Energy at Högdalenverket

    Type: 
    Product
    Objective:
    Technology:

    Högdalenverket is one of Europe’s most modern facilities for extracting energy from waste, producing electricity and heat from Stockholm’s combustible household waste and industry waste. This makes Högdalenverket an important component in the district heating network of southern Stockholm. The waste-fired Högdalenverket is one of Stockholm’s largest combined heat and power plants, providing environmentally friendly heat and electricity to large parts of southern Stockholm.

  • Hydrogen Production by a Novel Thermochemical Water Splitting Cycle

    Type: 
    Product
    Technology:

    Background: Currently hydrogen production is mainly based on steam reforming of methane gas or gasification of coal. These hydrogen production processes require methane or other fossil fuels as feedstock create unwanted carbon dioxide as a process by-product and require the use of capital and energy intensive separation unit operations to purify the hydrogen from undesirable by-products such as carbon monoxide and carbon dioxide. Extensive research has been done on identifying reactions that decompose water rather than carbon based fuels.

  • Dåva CHP

    Type: 
    Product
    Objective:
    Technology:

    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.

  • E.ON. CFB Waste Incineration Plant

    Type: 
    Product
    Objective:
    Technology:

    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.

  • New combined heat and power plant in Solna

    Type: 
    Product
    Objective:
    Technology:

    The energy company Norrenergi has been commissioned to build a biofuel-fired district heat plant in northern Kymlinge. The installation will secure the supply of electricity and heat in growing areas within the municipalities of Solna and Sundbyberg. Furthermore, thanks to the plant, the municipalities can count with reduced emissions of carbon dioxide by 15 %, which is in line with the Parliament’s fixed objective for reduced emissions.

  • New environmentally-friendly CHP plant in Igelsta

    Type: 
    Product
    Objective:
    Technology:

    Söderenergi invests 250 million Euros in a bio fuel-fired combined heat and power plant (CHP) in Igelsta. The CHP will be able to supply energy to close on 100.000 dwellings, which makes Igelsta to one of the biggest biofuel-fired heat-electric power plants in the world.
