First-of-its-kind isopentane waste- gas-to-power plant for Ghana

15 May 2018

GE Power and Marinus Energy are to collaborate on a pilot project to capture waste isopentane gas and use it as a fuel source for generating electricity. The Atuabo waste to power independent power project will use the isopentane to run a TM2500 mobile gas turbine installation, making it the first TM2500 based power plant in Sub-Saharan Africa to use isopentane gas. This gas would otherwise be flared.

The first phase of the Atuabo plant will have an installed capacity of 25 MWe. As additional gas is brought onshore, the plant will be expanded to 100 MW. Additional isopentane fuel will eventually be stripped off an offshore gas supply and processed at Atuabo by the Ghana National Gas Company.

The gas turbine will start on lean gas and transfer to the isopentane mix over time. The power plant is intended to operate at base load throughout its life. 

Other recent GE power projects in Ghana include the 400 MW Bridge project, the first LPG fired power plant in Africa and the largest LPG fired power plant in the world, and the 200 MW Amandi power plant, said to be one of the most efficient
power plants in the country.
