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

  • 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.

  • Waste incineration at Högdalenverket

    Type: 
    Product
    Objective:
    Technology:

    Högdalenverket, which is one of Europe’s most modern installations for energy extracted from waste, produces electricity and heat from Stockholm’s combustible household waste and industry waste. Högdalenverket is 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. It provides environmentally-friendly heat and electricity to large parts of southern Stockholm.

  • 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.

  • Solar thermal systems - Energy saving products

    Type: 
    Product
    Technology:

    Elsol is a solar company specializing in designing and marketing solar thermal systems cogeneration and energy saving products. The company manufactures solar hot water heaters solar flat plate collectors. Our solar and electric water tanks are manufactured by Rand energy systems Ltd. Rand’s solar and electric water tanks are available in a variety of volumes from 30 to 300 liters. Water tanks are obtainable in vertical or horizontal versions.

  • High Efficiency Solar PV and Thermoelectric Cogeneration

    Type: 
    Product
    Technology:

    Researchers at Purdue University have developed a cogeneration system that generates electricity from both solar energy and heat at a high efficiency up to 51 percent. It first splits the solar spectrum into two wavelength ranges high and low energy photons and then converts the high energy photons directly into electricity using photovoltaic cells capturing the low energy photons as heat using a reflecting selective solar absorber. The heat is then converted to electricity through a thermoelectric generator high-temperature heat exchanger and mechanical engine.

  • Lake Naivasha Dredging for Fertilizer Project

    Type: 
    Product
    Technology:

    The project shall establish a dredging complex on the shores of Lake Naivasha to mine the sediment and other debris on the bottom of the lake and convert the sediments into usable Biodeposit Agro and Biodeposit Elixir organic fertilizers. Escaping methane (CH4) shall be captured for cogeneration of up to 70 MW of clean energy. The project requires finance to construct a fertilizer industry in Kenya whose capacity would be about 180.00 tons per year for Biodeposit Agro fertilizer and 20.000 tons per year for Biodeposit Elixir fertilizer.

  • Villaya Microsol

    Type: 
    Product
    Technology:

    Microsol helps micro producers in the food textile and paper industries with processing their raw materials by automating some of their processes e.g. drying washing pasteurization etc. or in the tertiary sector such as tourist industry by providing the energy needed for many premium services electricity for HVAC refrigeration or security heat for hot water laundry or heating water for drinking or cooking. Located in a rural village Microsol can also meet some or all of the production needs of local residents water supply electrification of communal areas and so forth.

  • 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.

  • Övik Energi Cogeneration & District Cooling

    Type: 
    Product
    Objective:
    Technology:

    Hörneborgsverket, a biofuel based cogeneration plant, is the engine of Övik Energi’s energy production. Hörneborgsverket produce roughly three equal amounts of district heating, steam, and electricity. The steam is distributed to the neighbouring process industries – Domsjö Fabriker, AkzoNobel and SEKAB. Due to the industry’s need for steam, which is in demand throughout the entire year, the cogeneration plant is used to a greater extent, in comparison with power plants that only supply district heating, of which the demand fluctuates.
