Reduce GHG emissions

Reduce GHG emissions

  • Energy supply from waste

    Type: 
    Technology
    Sectors:
    Objective:

    The most commonly used conversion methods – combustion of waste to produce heat or electricity; anaerobic digestion to produce methane for heat or power production etc. all are well-established and commercial technologies. A further set of conversion processes – for example, the production of liquid fuels from cellulosic materials by biological or thermochemical conversion processes, such as pyrolysis – are at earlier stages of commercialisation or still under development.

  • On-shore wind

    Type: 
    Technology
    Sectors:
    Objective:

    The conversion of kinetic energy in wind into electrical power is known as wind energy. There are a number of ways in which this conversion can be done but the design dominating the market is known as the horizontal axis wind turbine (HAWT) with its archetypal three-bladed rotor. Wind energy is actually a form of solar energy; the temperature differences caused by the sun shining on the earth act, along with other factors, to cause large bodies of air, winds, to move across the face of the planet.

  • 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.

  • Recycling of Waste Electronic and Electrical Equipment (WEEE)

    Type: 
    Technology
    Sectors:
    Objective:

    According to the EC (19 November, 2008) “waste means any substance or object which the holder discards or intends or is required to discard.” Recycling materials and products – that are considered waste - is an ancient practice which shows that in times of resource scarcity (i.e. shortage of virgin materials) societies attach more economic and societal value to their own waste. This implies that throughout time the definition of waste can change as well. Generally speaking longer use or reuse of materials and products this is often mainly to cover a society’s 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).

  • 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.

  • Co2 Bio-Mitigation using Microalgae

    Type: 
    Technology
    Objective:

    What is Micro-algae

    Micro-algae are a group of unicellular or simple multicellular fast growing photosynthetic microorganisms that can conserve CO2 efficiently from different sources, including the atmosphere, industrial exhaust gases, and soluble carbonate salts. Micro-algae act as a major system for converting atmospheric CO2 into lipids under sunlight and increase the output of algal oil. The enzyme acetyl Co-A carboxylase (ACCase) from micro-algae catalyzes the key metabolic step in the synthesis of oil in algae.

  • Biodigester

    Type: 
    Technology
    Sectors:
    Objective:

    What are biodigesters?

    A biodigester system utilizes organic waste, particularly animal and human excreta, to produce fertilizer and biogas. A biodigester consists of an airtight, high-density polyethylene container within which excreta diluted in water flow continuously and are fermented by microorganisms present in the waste. The fermentation process is anaerobic, i.e., it takes place without oxygen, and the bacteria responsible for decomposition are methanogenic (i.e., they produce methane, also known as biogas).

  • Liquefied Natural Gas in trucks and cars

    Type: 
    Technology
    Sectors:
    Objective:

    The use of Liquefied Natural Gas (LNG) in transport is a suitable option to power large long-distance trucks in areas where gas is transported as liquefied natural gas because there are indigenous gas supplies and no gas network. The use of LNG in passenger cars is far less viable because on average passenger cars stand idle more often, which would give rise to high evaporative losses.

  • 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.
