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.

    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.

    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.

    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.

    Objective:
    Technology:

    CHP (Combined Heat and Power) units produce simultaneously heat and power from fuel gas, resulting in higher efficiency compared with separate provision of heat and power.
    Micro Cogeneration CHP units in a wide range of small-scale applications both in public and private sectors, including schools, restaurants, nursing homes, health centers, offices, hotels and leisure centers, with a typical electrical power demand below 35 kW.
    Efficiency is especially high in colder regions due to high demand for waste heat for heating or hot water supply.

    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.

    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.

    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.
