Lake Kivu is a deep lake in Rwanda, whose water contains high amounts of carbon dioxide, hydrogen sulphide (from volcanic activity) and methane (produced from deep water bacteria).
Engineers have devised a system to remove these three gasses, then re-introduce the carbon dioxide and hydrogen sulfide back into the water, leaving only the methane. This methane (85% pure) will be used as fuel to generate electricity.
This system could produce enough electricity to meet Rwanda’s needs for the next 400 years, instead of burning wood from logging which currently accounts for 90% of Rwanda’s energy production.
