(International Research Institute Stavanger (Norway), Vrije Universiteit Brussel (Belgium), University of Cape Town (South Africa), Fatih University (Turkey) and Ain Shames University (Egypt).
Ad-Pow-Gen is an ERAfrica project
Ad-Pow-Gen aims to evaluate and prove the concept of an advanced, high-efficient, low-cost power generation unit with minimum carbon emission from hybrid-fuel supplies. It will consist of two major subsystems and several other components. The two major subsystems are an advanced gas turbine power cycle to convert thermal energy into mechanical energy and a high speed generator, driven by the turbine for electric power generation.
The technical objective of the project is to develop and demonstrate a concept for integrating various sources of renewable energy (RE) and alternate fuel sources into both bulk power generation and distributed micro-generation (DMG) systems [BP1]
In addition to the main gas turbine process, converting the thermal energy from various thermal and sustainable energy sources into mechanical energy and electricity is a dual vane compressor used to further boost the performance of the turbine. This novel compressor will be also designed and integrated within the project. Solar energy will be source for thermal energy to preheat compressed air before entering the combustor chamber and therefore contribute to reducing fuel consumption. It will be also used to produce hydrogen for the highly fuel flexible combustion system.
Besides solar energy will be also biogas or biodiesel usable as fuel. Fuel mixing reduces emissions significantly even if fuelled with natural gas, which is used as a backup fuel in case of insufficient availability of renewable based fuel. For further optimising the overall energy balance of the plant will be exhaust gas of the turbine utilized to preheat the compressed air before entering the concentrated solar thermal air heater and the combustor. Remaining heat available at temperatures of about 200 deg Celsius will be further used for industrial thermal applications such water desalination.
The project aims at demonstrating the feasibility of the concept. It is executed via different work packages, several of which are executed in parallel.
