Nigeria - ColdHubs is supplying smallholder farmers with walk-in coldrooms using a pay-as-you-store model. This 100% solar-powered innovation is reducing food waste, increasing smallholder farmers' climate resilience, and empowering women retailers.
Cooling is becoming a rapidly emerging demand in developing countries, which signifies that the building design and shell measures need to reduce cooling loads, and the efficiency of air-conditioning will need to be improved. Air conditioning systems are implemented in numerous sectors, namely buildings, industry and transport. They are distinguished in two main categories, room air conditioners and central air conditioners.
The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.
Background: Stanford researchers at the Fan Group have developed a novel method of passively cooling solar cells via a radiative cooling mechanism. The pyramid structures made of silica glass (shown in image below) provide maximal radiative cooling capability. Technology Description: We have developed a way of passively cooling solar cells that are exposed to the sun and hence heat up via a radiative cooling mechanism. This is an enormously important issue since solar cells operate at high temperatures which degrade both their efficiency and long-term durability.
Background: Calixarene-type compounds and self-assembled and spherical hexamers of calixarene derivatives have been proposed for various applications. Typically these compounds’ structures are maintained through stronger chemical bonding such as covalent bonding or hydrogen bonding. Technology Description: The present invention describes the use of self-assembled calixarene guest-host assemblies utilizing the weaker van der Waal forces for structural stability and guest confinement. These guest-host assemblies have shown high temperature stability.
The major commodity chemical 12-propanediol (also known as 12-PD or propylene glycol) is used in certain resins laundry detergents pharmaceuticals cosmetics and antifreeze. More than a billion pounds of the compound are produced annually in the United States. Conventionally made from petrochemicals and involving several toxic compounds and large quantities of water 12-PD can be produced more sustainably from glycerin. Using microorganisms capable of secreting the compound from sugar is an even more environmentally responsible alternative.
“Les niveaux des ambitions de reduction des GES du scenario d’atténuation par rapport au scenario de base sont de 29% pour l’agriculture, 31% pour l’énergie et 21% pour les forêts et le changement d’utilisation des terres.” The GHG mitigation scenario’s emission reduction levels, relative to the baseline scenario, are: 29% for agriculture, 31% for energy, and 21% for forests and land-use change.
