Life cycle assessment of Peat use for Energy Generation (Case Study: GISHOMA PEAT POWER PLANT)

Abstract

Peat is increasingly being used for power generation in the world including Rwanda. Nowadays, there is a planning from the government of Rwanda to expend generation from peat in the energy Sector strategic plan made to achieve the target for 100 % household connected to electricity in 2024.From different researchers, it is indicated that an assessment of potential occupational health and safety (OH&S) concerns related to usage of peat fuels in combustion-based generation is needed.In the Ireland , the combustion of peat for energy generation contributes significantly to greenhouse gas (GHG) emissions, with current levels of combustion resulting in the emission of approximately 2.7 Mt of CO2 per annum and is equivalent to 4.1% to Irelands overall GHG emissions.The literature review was made on potential OH&S issues associated with the use of peat-based fuel for electricity generation at the utility. The three potential exposures were considered such as pre-combustion exposure to material associated with the fuel, the exposure to combustion products, and on post-combustion exposure on ash and residues. Measuring the ash content and viewing the ash disposal issue were observed during the visit done at Gishoma Peat Power Plant. Results indicated that the use of peat for power generation will contribute to greenhouse gases emissions in the Rwandan Environment. Some Counter measures to reduce these gases will be indicated. In light of limited available information due to lack of adequate tools, additional studies at power plants utilizing peat fuel for electrical power generation variables technologies to be used to reduce emissions are recommended
