Belgrade's district heating (DH) system is one of the largest in Europe with a total network length of 1420 km and capacity of over 2800 MW. The majority of the network is run on the natural gas boilers and fuel oil boilers with no waste heat from cogeneration or other sources being used and very little renewables (0,75% of capacity). Energy efficiency of the building stock is quite low, and the intensity of energy consumption is high. The city needs harmonized approaches to efficiency.

United Nations Industrial Development Organization (UNIDO) is looking for member of the CTCN Network that can provide services related to Green technology deployment in industrial zones in Senegal.
Senegal benefits from a buoyant economy, nevertheless facing a number of challenges. In the country’s development plan - Plan Senegal Emergent (PSE) - a key component to address these issues is the development of integrated industrial zones. These shall attract foreign investment, bring new technologies and increase productivity and competitiveness.
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.
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
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).
