ClimateTechWiki

ClimateTechWiki offers a platform for a wide range of stakeholders in developed and developing countries who are involved in technology transfer and the wider context of low emission and low vulnerability development. ClimateTechWiki offers detailed information on a broad set of mitigation and adaptation technologies.

  • CO2 capture technologies

    Type: 
    Technology
    Sectors:
    Objective:

    Carbon capture and storage (CCS) is a combination of technologies designed to prevent the release of CO2 generated through conventional power generation and industrial production processes by injecting the CO2 in suitable underground storage reservoirs. Basically, capture technology separates CO2 emissions from the process, after which the compressed CO2 is transported to a suitable geological storage location and injected. Feasible methods of transporting of CO2 include both pipelines and shipping.

  • Sea walls

    Type: 
    Technology
    Sectors:
    Objective:

    Seawalls are hard engineered structures with a primary function to prevent further erosion of the shoreline. They are built parallel to the shore and aim to hold or prevent sliding of the soil, while providing protection from wave action (UNFCCC, 1999). Although their primary function is erosion reduction, they have a secondary function as coastal flood defences.

    The physical form of these structures is highly variable; seawalls can be vertical or sloping and constructed from a wide variety of materials. They may also be referred to as revetments.

  • Smart grid

    Type: 
    Technology
    Objective:

    The smart grid is the state-­‐of-­‐the-­‐art technology for electrical system that can sensibly execute the operations to all interconnected elements -­‐ from generator to consumers. Smart grid simply converts the conventional power grid towards the modern grid in order to regulate sustainable, economic and reliable electricity (Massoud &Wollenberg, 2005 and Gellings, 2009). Smart grid intelligently executes operations from primary and secondary generators through the transmission and distribution network to the different types of consumers.

  • Optimising aviation

    Type: 
    Technology
    Sectors:
    Objective:

    Improved air traffic management techniques like to avoid flying holding patterns, “green landings” and the use of relatively low speed airplanes for domestic aviation can reduce the emission of greenhouse gases substantially. Depending on their penetration up to 3% CO2 emission reduction can be achieved for green landings and 10-60% CO2 emission reduction for low speed airplanes. Moreover, these techniques will lower the NOx and soot emissions, thereby improving the air quality around the airport.

  • 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. 

  • Biochar

    Type: 
    Technology
    Sectors:
    Objective:

    Biochar is a charcoal-like substance produced from agriculture and forest wastes which contains 70% carbon. It is used as soil enhancer to increase fertility, prevent soil degradation and to sequester carbon in the soil. Biochar can store carbon in the soil for as many as hundreds to thousands of years. Biochar can be produced through pyrolysis, gasification and hydrothermal carbonization, which leaves bio-oil and syngas as by-products. Small scale production can be through pyrolysis using modified stoves and kilns which are low cost and relatively simple technologies.

  • Building-integrated wind turbines

    Type: 
    Technology
    Sectors:
    Objective:

    Wind energy technologies can be classified into two categories – macro wind turbines that are installed for large-scale energy generation such as wind farms, and micro wind turbines used for local electricity production. Micro wind turbines are suitable for application at the building scale and are called ‘building-integrated wind turbines’. The main components of a wind turbine include blades, rotor, gearbox and generator. Small wind turbines were originally designed with a horizontal axis, also known as HAWTs.

  • 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).

  • Manure coverage

    Type: 
    Technology
    Sectors:
    Objective:

    Manure coverage is the practice of covering the surface of manure with materials of certain thickness instead of the traditional method of piling up manure to be exposed to air. Manure coverage changes the amount of manure surface in contact with air. Due to some reactions, i.e., a series of physical, biological and chemical reactions, it can reduce GHG emissions.

  • Gasification of waste

    Type: 
    Technology
    Sectors:
    Objective:

    Thermal gasification of municipal solid waste (MSW) is a chemical process that generates a gaseous, fuel-rich product. This product can then be combusted in a boiler, producing steam for power generation. Just as with combustion of MSW, thermal MSW gasification does not necessarily compete with recycling programmes, but should be considered complementary in any generically constructed MSW plan.
