Evaluation of the Potential of Hyacinth as a Biogas Feedstock for Electricity Generation in Kenya

Water hyacinth is currently considered a menace due to its negative social and economic impacts. However, the weed may have potential as a renewable energy source. This research project aims to test the viability of the weed as a biogas feed stock and also develop a model hyacinth-run biogas power generator system to demonstrate the potential of this weed for rural electrification. The project is also evaluating a portable (flexi-) biogas system made by a local company. The flexi-biogas system has potential to improve the uptake of this technology since it is made from long-lasting UV resistant plastic which is cheaper and easier to install than the traditional fixed dome digesters which require building materials and skilled labour.

Thermal Gasification of Rice husks for Electricity Generation in rice Growing Areas in Kenya

Most of the biomass from agriculture is considered as waste materials and is disposed of through such methods as open burning with no energy recovery options, leading to air pollution and contributing to climate change due to the emission of greenhouse gases such as carbon dioxide. In this research project, rice husks from the rice-growing area of Mwea will be gasified through partial combustion at high temperatures. The resulting combustible gas will then be used to run an internal combustion engine in order to produce electricity. The research attempts to demonstrate an alternative method of utilizing waste as a sustainable form of Renewable Energy which can be used for rural Electrification.

These research projects are being conducted in collaboration with several researchers from Ashikaga Institute of Technology (AIT), including Professor Nemoto, among others.
