Reduce GHG emissions

Reduce GHG emissions

  • District heating and cooling

    Type: 
    Technology
    Objective:

    The district heating net is a pipe network that supplies heating and hot water for connected consumers from a central power plant. It is a more efficient way to provide heat and power compared to localized boilers. District cooling is the cooling equivalent of district heating. Working in accordance to similar principles, district cooling delivers chilled water to buildings like offices and factories. Trigeneration is when electricity, heating and cooling are combined in the same plant.

    Responds to the following needs

  • Compressed Air Energy Storage (CAES)

    Type: 
    Technology
    Objective:

    Energy storage provides a variety of socio-economic benefits and environmental protection benefits. Energy storage can be performed in a variety of ways. Examples are: pumped hydro storage, superconducting magnetic energy storage and capacitors can be used to store energy. Each technology has its advantages and disadvantages. One essential differentiating characteristic of the different technologies is the amount of energy the technology can store and another is how fast this energy can be released. This technology description focuses on Compressed Air Energy Storage (CAES).

  • Small-scale Combined Heat and power

    Type: 
    Technology
    Objective:

    Co-generation is the combined production of useful thermal energy and electricity (Combined Heat and Power, CHP) from the same primary fuel. CHP can take on many forms and encompasses a range of technologies, but will always be based upon an efficient, integrated system that combines electricity production and heat recovery. By using the heat output from the electricity production for heating or industrial applications, CHP plants generally convert 75-80% of the fuel source into useful energy, while the most modern CHP plants reach efficiencies of 90% or more (IPCC, 2007).

  • Ethanol Cook Stoves

    Type: 
    Technology
    Objective:

    Alcohol burning stoves based on ethanol can be used for cooking, water heating and heating of buildings. The technology can be applied in households, institutions (e.g. schools) and industries where it is used for boiler heating. Ethanol is produced from sugar plants or other sources of biomass. An advantage of the technologies is that ethanol burning does not have the air pollution problems of simple biomass burning for cooking purposes. As ethanol provides a higher heat flux with no soot or smoke, cooking and hot water production can take place faster and pollution free.

  • Methanol cook stoves

    Type: 
    Technology
    Objective:

    Alcohol burning stoves based on methanol can be used to supply a cooking service, water heating and heating of buildings. The technology can be applied in households, institutions (e.g. schools) and industries where it is used for boiler heating.

  • Energy efficient refrigerators

    Type: 
    Technology
    Objective:

    Refrigerators are used in households across the world to store food at a temperature of about 3 to 5 °C (37 to 41 °F) in order prevent it from spoiling. This technology description focuses on refrigerators for residential use and on energy efficiency performance only. It does not take into account potential GHG effects caused by the refrigerant.

  • Energy Savings in buildings

    Type: 
    Technology
    Objective:

    Technologies and measures which are aimed at reducing the use of energy in buildings could have several advantages, such as lower energy bills, increasing comfort of living or working, and reduced impact on the environment, including reduction of CO2 emissions. The options considered for energy savings particularly leading to CO2 emission reductions include the following:

  • Improved Cook Stoves

    Type: 
    Technology
    Objective:

    Since about 1.5 billion people in the world use traditional stoves for cooking (and heating), efforts to improve the efficiency of cookstoves have been increasingly popular in the developing world. Improved stoves come in different forms and sizes. 

  • Large-scale Combined Heat and Power

    Type: 
    Technology
    Objective:

    Co-generation is the combined production of useful thermal energy and electricity (Combined Heat and Power, CHP) from the same primary fuel. CHP can take on many forms and encompass a range of technologies, but will always be based upon an efficient, integrated system that combines electricity production and heat recovery. By using the heat output from the electricity production for heating or industrial applications, CHP plants generally convert 75-80% of the fuel source into useful energy, while the most modern CHP plants reach efficiencies of 90% or more (IPCC, 2007).

  • Micro-grid

    Type: 
    Technology
    Objective:
    Microgrid is a localized grouping of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized electrical grid (macrogrid), but can disconnect and function autonomously as physical and/or economic conditions dictate. By this way, it paves a way to effectively integrate various sources of distributed generation, especially Renewable Energy Sources. It also provides a good solution for supplying power in case of an emergency by having the ability to change between islanded mode and grid-connected mode.
