Clarke Energy is installing a 2 MW INNIO Group gas engine package, containerised by Clarke Energy, at Côte d'Ivoire's first-ever trigeneration project.
The trigeneration project for Dream Cosmetics produces electricity, steam and chilled water from the same fuel. Founded in 2007 and based in Cairo, Egypt, Dream Cosmetics aims to be the top cosmetics manufacturer in Middle East.
A spokesman comments:
"The Côte d'Ivoire project is based on 2 MW of particularly robust INNIO Group gas engine technology, containerised by Clarke Energy and specially adapted for the tropical environment."
The energy profile of the project can be summarised as follows:
*Waste heat is recovered to produce steam at 11 bar
*Chilled water is produced at 5°C
*Reliable electricity is generated to power the plant
The whole site depends on trigeneration, also known as Combined Cooling, Heat, and Power (CCHP), an advanced energy generation technology which extends the concept of cogeneration (CHP) by adding cooling to the electricity and heat outputs. In a trigeneration system, a single heat source, such as natural gas, biogas, biomass, or solar thermal energy, is used to generate electricity. The waste heat from electricity production is then captured and used for heating and, through absorption chillers or thermally driven refrigeration systems, for cooling.
There are three separate elements:
Electricity Generation: A prime mover, such as an internal combustion engine, gas turbine, or steam turbine, converts fuel into mechanical energy, which is then transformed into electricity via a generator.
Heat Recovery: The system captures the residual heat from the electricity generation process, which would otherwise be wasted, and uses it for space heating, water heating, or industrial processes.
Cooling Production: The recovered heat can also drive an absorption chiller or other thermally driven refrigeration system to produce cooling for air conditioning or industrial needs.
This integrated approach allows a single fuel input to meet three energy demands simultaneously, significantly improving overall energy efficiency. Trigeneration systems can achieve overall efficiencies of up to 90%, compared to 33–40% for conventional power plants. By producing electricity, heat, and cooling locally, facilities can reduce energy bills and potentially sell excess electricity back to the grid. Utilising waste heat reduces greenhouse gas emissions and lowers the need for separate heating and cooling systems. Localised trigeneration provides redundancy and a stable energy supply, which is particularly valuable for mission-critical facilities.
