    Publication date:
    Objective:
    Sectors:

    The UNFCCC Climate Technology Centre and Network (CTCN), the World Intellectual Property Organization’s Initiative (WIPO), the Northeast Water Innovation Network (NEWIN), and InvenTrust are inviting to join an innovation competition to address two key challenges, essential in pathways to a global, safe, and sustainable future:

    • Energy Efficient Water Desalination
    • Eliminating Leakage in Water Distribution

  • TTD Industrial waste treatment

    Type: 
    Product

    Tamar Technological Development r seals eliminate leakages in the main factories in Israel and were successfully installed in .USA Italy Brazil and Netherlands. The new MTZ shaft sealing technology has been introduced by Tamar Technologies This product is especially effective in sealing pumpage with particulates as well as for clear liquids It has application for pumps mixers agitators ribbon blenders and fans in addition to sealing shafts for dry powder handling. The Tamar Seal is analogous to a double mechanical seal that uses a flexible sealant as a barrier fluid.

  • Seawater stored in rock in Stockholm provides efficient district cooling

    Type: 
    Publication
    Publication date:
    Objective:

    With a water-filled rock chamber beneath Kungsholmen in Stockholm, the energy company Fortum has been able to substantially increase capacity in the city’s network for district cooling. The ordinary cooling plants can be phased out, and both high electricity needs and the risk of leakage of ozone-depleting substances will disappear along with them.

    Positive environmental and economic impacts

    • At full capacity, electricity consumption can be reduced by 45 GWh per year.

  • Water Infrastructure Monitoring

    Type: 
    Product

    TaKaDu’s solution takes SCADA readings (flow pressure quality and other measurements) and GIS data about the water network cleans them of “noise” and constructs a model of how the water network behaves adjusting for the day of the week hour seasonality and operations and maintenance activity. It then monitors the network to detect anomalies based on the model and alerts when they happen. This lets water utilities “see” the network and detect leaks and other anomalies before they become much larger operational issues.

  • Improving the efficiency of intermediate band quantum dot solar cells

    Type: 
    Product

    Conventional single junction (e.g. silica GaAs) solar cells absorb photons only from a limited range of spectra (i.e. above the band-gap photons) missing almost 60% of the energy that can potentially be obtained from the entire solar spectrum. Intermediate band (IB) solar cells with Quantum Dots (QD) tuned to absorb photons from a wider range of wavelengths offer a solution to this problem. However the current models for IB solar cells come with disadvantages of current leakage low efficiency and low open circuit voltage.

  • Waste water treatment and Water resources management

    Type: 
    Product

    Lesico CleanTech is a pioneer in delivering sustainable technologies which recycle or minimize the volume of liquid waste primarily desalination rejected brine. The solutions not only help users comply with stringent regulation but result in substantial savings in real estate installation and operational costs.

  • Boron and Lithium Isotopic Method for Tracing Hydrocarbons and Their By-Products

    Type: 
    Product

    Background: As petroleum consumption continues to rise the world is turning to unconventional oil sources such as kerogen shale and bituminous sands in order to keep up with global demand. Satellite imagery gravity meters and magnetometers are typically used to pinpoint ideal locations for drilling over conventional oil or gas reserves. However differentiating unconventional oil sources from other layers of rock is difficult due to their similar densities so instead organic biomarkers are used to trace hydrocarbons (and their by-products) back to their source rock.
