Ghanaian-owned power company, Marinus Energy, will be partnering with GE Power, a subsidiary of General Electric on innovative energy solutions, which will make use of the country’s flared gas that would have gone to waste.

The 25MW power plant, anticipated to cost $25 million, will be stationed at Atuabo in the Western Region, and will utilise Isopentane gas as a fuel source, reports the Graphic.

GE said the Atuabo waste-to-power Independent Power Project would be the first TM 2500 power plant in sub-Saharan Africa to use Isopentane gas as a fuel source and would run on its latest TM 2500 gas turbines.

Commenting on the project, the strategic advisor of Marinus Energy, Fred Asamany, said: “Not only is the Atuabo waste-to-power plant enabling our company to lead in innovative energy solutions in Ghana but by using a fuel source which would otherwise have been flared as waste, we are further reducing emissions and costs.

“This is good for our business and the climate and eliminates potential environmental hazards facing the local community. GE is offering an innovative solution which gives us the confidence to move from pilot to commercial operations.” Read more...

Phase one of Atuabo waste-to-power plant

In the first phase, Atuabo is expected to convert the Isopentane fuel into up to 25MW of power, generating enough electricity to supply power to more than 100,000 Ghanaian households, and as additional gas is brought onshore, the plant will add on additional gas generating units of up to a capacity of 100MW.

It is envisaged that any additional Isopentane fuel will ultimately 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, while the power plant is intended to operate at base-load throughout its life.

CEO of GE Ghana and of GE’s gas power systems in sub-Saharan Africa, Leslie Nelson, commented: “The TM2500 can also achieve full power approximately within 10 minutes, making it ideal for providing a base-load bridge for permanent power installations or generating back-up power for factories and industries.”

Nelson added: “We intend to have that particular technology on inventory because globally we can use it to move quickly in emergency situations as we’ve done in this country before, we are doing in Angola and we have done in Nigeria.

“Secondly, the efficiency is very high. Thirdly, it is mobile and so you can actually move it from one location to another and the good thing about that technology is that we are building a fleet of those turbines in-country.”
