Kenyan geothermal company installs Africa’s first steam cereals dryer

KENYA – Geothermal Development Company (GDC) has installed a semi-commercial cereals dryer at the Menengai Geothermal project funded by the Icelandic International Development Agency with a capacity to dry 20 tonnes of cereals per day.

“This is a major breakthrough in Kenya’s geothermal sector,” said GDC managing director Johnson ole Nchoe.                                                  

He said the corporation will pilot the viability of the drier and then scale it up for commercialisation urging the private sector to consider venturing into direct uses of geothermal energy, arguing it helps to cut costs of energy and reduces emissions.

“The use of geothermal steam in industrial processes like drying cereals will dramatically cut the cost of energy. It will also help to reduce massive post-harvest losses associated with poor and expensive drying,” he said.

Agusta Gisladottir, Iceland’s director for Regional Development Cooperation and Partnerships, noted that direct uses are a key component of the geothermal economy that needs to be pursued with rigour. She led a delegation from Iceland’s Ministry of Foreign Affairs.

“We are pleased to see the progress of this project. The Iceland government is impressed by the dryer. I am pleasantly informed this is the only one of its kind in Africa. It goes to show that we can actually focus on this other area of geothermal energy utilisation other than for electricity,” Gisladottir said.

She urged the GDC to commercialise the immense treasure at its disposal. The drier adds another feather to GDC’s unique portfolio of direct uses.

At Menengai, the GDC has successfully piloted four prototypes on direct uses of geothermal heat with spectacular results. Through financing from Power Africa, it established the first milk pasteuriser in Africa that uses geothermal steam as opposed to wood or heavy oil.

There is also a fishpond that is heated using geothermal steam. A heated pond accelerates the growth of tilapia by 30 per cent. Another exciting pilot is a green-house heated using geothermal steam and a geothermal heated Laundromat.

If optimally exploited, geothermal has umpteen uses beyond the generation of electricity. This will make Kenya a competitive investment hub in the region.

The GDC is banking on these and many other innovations to boost the manufacturing sector. For instance, in manufacturing, geothermal steam displaces the use of heavy industrial oil normally used to heat industrial boilers.

“Industrialists, especially those who use boilers, have a great chance to invest in geothermally heated facilities. That way, they will save a great deal on energy. Geothermal is the real deal for any investor,” Nchoe said.
