Implementation of a district cooling system on the Punggol digital district in Singapore
ENGIE will design the integrated district cooling system (30,000 tons of refrigeration, 105 MW) that will serve both the Jurong Town Corporation…
The project aims to supply Reims with 90% renewable heat by 2024. This ambitious project, financially supported by Ademe, results from the common desire of Grand Reims and ENGIE Solutions to green the Reims heating network and thus act on air quality and the climate performance of the territory.
Operated through a public service delegation by Soccram, a local subsidiary of ENGIE Solutions, the Reims heating network provides heating and domestic hot water to the equivalent of 17,000 homes, mainly from the incineration of waste from the Centre de Valorisation Energétique (C.V.E) Remival and woodchips (shredded wood from logging residues, by-products from the wood industry).
The current rate of renewable energy and energy recovery (ReR&R) of 60%, which the project to integrate recovered wood will bring to 90% by 2024. For this, it is necessary to adapt the existing boiler room. 2,500 additional housing equivalents will benefit from this renewable heat at the end of 2022, as the Châtillons district will soon be connected to the network.
In total, from 2024, the equivalent of 20,000 homes will benefit from this heating and domestic hot water solution.
To green the urban heating and cooling network, ENGIE Solutions is deploying its expertise, in particular by removing coal from the energy mix and by integrating wood biomass, ultimately up to 46%. The circular economy is favored by the use of wood from the region, from waste collection centers, demolitions or salvage from industries and businesses.
The addition of recovered wood, from furniture and construction waste, among the sources of heat production in the Greater Reims network, has many advantages:
on which the project has a significant impact
Scope 1 : Exit from coal and integration of recovery wood into the energy mix of the Reims urban network
Division by 6 of CO2 emissions
Quantification : Reduction of 19 600 tCO2e per year
The emission factor was 120 gCO2e/kWh. Completion of the project significantly reduces this factor to reach 20 gCO2e/kWh of heat produced (division by 6). Based on a projection of approximately 196 GWh produced per year, the associated reduction in CO2 emissions therefore amounts to 19,600 tCO2e/year.

Project reproducible to any heating network subject to the territorial potential for recovery wood availability
