Comparative Overview of Gases Discharged from Menengai and Olkaria High Temperature Geothermal Fields, Kenya
Proceedings 5th African Rift geothermal Conference Arusha, Tanzania, 29-31 October 2014 Comparative Overview of Gases Discharged from Menengai and Olkaria High Temperature Geothermal Fields, Kenya 1Jeremiah K., Ochieng L., Mibei G., Kanda K. and Suwai J. Geothermal Development Company P.O.Box 17700 – 20100, Nakuru Kenya [email protected] Key words: Menengai, reservoir characteristics, Olkaria, discharge vapors, triangular diagrams ABSTRACT An analogy of representative gas compositions from wells drilled into the Menengai and Olkaria volcanic geothermal systems is presented in this paper with a view of drawing parallels as well as identifying variances in the characteristics of the reservoirs tapped by the wells. This contribution seeks to provide an insight into the possible processes that govern the composition of well discharge vapors as well as characterize the Menengai and Olkaria geothermal reservoirs. To achieve this, triangular diagrams comprising two major chemical constituents, H2O and CO2, together with other gas species H2S, H2, CH4 and N2 were employed to compare the chemical characteristics of vapors discharged from these two systems. It is found that the Olkaria reservoir fluids generally exhibit high H2O/CO2 ratios relative to the Menengai fluids. This is attributed to variations in CO2 gas content. High H2S content seems to characterize Menengai wells, particularly those that discharge from the vapor dominated zones. This inference is indicative of either a higher flux of magmatic gas or enhanced boiling in the reservoir as a consequence of a higher heat flux. The latter is found to be common in the wells as this inference is also complemented by the significantly high H2 content reported. -

BRIEFING NOTE November 2013 UP IN SMOKE? MAASAI RIGHTS IN THE OLKARIA GEOTHERMAL AREA, KENYA he Olkaria geothermal power generation project is Ttouted as the largest such project in the world. Lo- cated approximately 120 km west of Nairobi, in Nakuru County, Kenya, the Olkaria geothermal field covers ap- proximately 75 sq. km and was gazetted as a Geothermal Resource Area in 1971. Three power stations are cur- rently adding 158 MW1 to the national grid while a fourth is under construction. The Kenya Electricity Generating Company (KENGEN), a wholly-owned state corporation, operates three of the four power stations while Orpower4 Inc, a wholly-owned subsidiary of US-based Ormat Tech- nologies, will operate the fourth. The Olkaria geothermal power projects generate in- come by selling electricity to the Kenya Power and Light- ing Company, a government-owned power distribution monopoly. Olkaria is also registered as a Clean Develop- ment Mechanism (CDM) project under the Kyoto Protocol to the United Nations Framework Convention on Climate Change. 2 The Olkaria geothermal power generation project is being funded by the Government of Kenya, and through loans from the World Bank, European Investment Bank, Deutsche Investitions- und Entwicklungsgesellschaft mbH,3 KfW Entwicklungsbank (KfW Development Bank) and the Overseas Private Investment Corporation.4 While the Olkaria geothermal power project lights up the nation, however, the Maasai people living in the area have consistently raised concerns that the project is dimming their lives. Olkaria has been their only home since the 18th century. And not only are they having to 1 Olkaria I (45 MW) and Olkaria II (65 MW), with a third private plant Olkaria III (48 MW) 2 An international agreement linked to the United Nations Framework Con- vention on Climate Change, which commits its Parties by setting interna- tionally binding emission reduction targets: http://cdm.unfccc.int/Projects/ DB/DNV-CUK1276170328.71/view. -

Lake Magadi Tilapia (Alcolapia grahami) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, March 2015 Revised, August 2017, October 2017 Web Version, 8/21/2018 1 Native Range and Status in the United States Native Range From Bayona and Akinyi (2006): “The natural range of this species is restricted to a single location: Lake Magadi [Kenya].” Status in the United States No records of Alcolapia grahami in the wild or in trade in the United States were found. The Florida Fish and Wildlife Conservation Commission has listed the tilapia Alcolapia grahami as a prohibited species. Prohibited nonnative species (FFWCC 2018), “are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed or used for commercial activities.” Means of Introductions in the United States No records of Alcolapia grahami in the United States were found. 1 Remarks From Bayona and Akinyi (2006): “Vulnerable D2 ver 3.1” Various sources use Alcolapia grahami (Eschmeyer et al. 2017) or Oreochromis grahami (ITIS 2017) as the accepted name for this species. Information searches were conducted under both names to ensure completeness of the data gathered. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing According to Eschmeyer et al. (2017), Alcolapia grahami (Boulenger 1912) is the current valid name for this species. It was originally described as Tilapia grahami; it has also been known as Oreoghromis grahami, and as a synonym, but valid subspecies, of -

Biogeochemistry of Kenyan Rift Valley Lake Sediments
Geophysical Research Abstracts Vol. 15, EGU2013-9512, 2013 EGU General Assembly 2013 © Author(s) 2013. CC Attribution 3.0 License. Biogeochemistry of Kenyan Rift Valley Lake Sediments Sina Grewe (1) and Jens Kallmeyer (2) (1) University of Potsdam, Institute of Earth and Environmental Sciences, Geomicrobiology Group, Potsdam, Germany ([email protected]), (2) German Research Centre for Geosciences, Section 4.5 Geomicrobiology, Potsdam, Germany ([email protected]) The numerous lakes in the Kenyan Rift Valley show strong hydrochemical differences due to their varying geologic settings. There are freshwater lakes with a low alkalinity like Lake Naivasha on the one hand and very salt-rich lakes with high pH values like Lake Logipi on the other. It is known that the underlying lake sediments are influenced by the lake chemistry and by the microorganisms in the sediment. The aim of this work is to provide a biogeochemical characterization of the lake sediments and to use these data to identify the mechanisms that control lake chemistry and to reconstruct the biogeochemical evolution of each lake. The examined rift lakes were Lakes Logipi and Eight in the Suguta Valley, Lakes Baringo and Bogoria south of the valley, as well as Lakes Naivasha, Oloiden, and Sonachi on the Kenyan Dome. The porewater was analysed for different ions and hydrogen sulphide. Additionally, alkalinity and salinity of the lake water were determined as well as the cell numbers in the sediment, using fluorescent microscopy. The results of the porewater analysis show that the overall chemistry differs considerably between the lakes. In some lakes, concentrations of fluoride, chloride, sulphate, and/or hydrogen sulphide show strong concentration gradients with depth, whereas in other lakes the concentrations show only minor variations. -

Direct Utilization of Geothermal Resources in Kenya
Proceedings World Geothermal Congress 2010 Bali, Indonesia, 25-29 April 2010 Direct Utilization of Geothermal Resources in Kenya John Lagat Kenya Electricity Generating Company Ltd, P. O. Box 785 Naivasha 20117 E-mail: [email protected] Keywords: Geothermal, direct use, balneology, space 38oE heating, greenhouses, agriculture, aquaculture, industrial North Island processes 4oN L. Turkana ETHIOPIA ABSTRACT Central Island Geothermal resources in Kenya are mainly located along the Kenyan Rift, which is part of the eastern arm of the South Island African Rift. The primary forms of utilization of Cenozoic Barrier Volcano geothermal energy in Kenya currently are mainly electric volcanics power generation (168 MWe) and direct uses (~18 MWt) to UGANDA Namarunu a small extent. Though about 99% of geothermal utilization in the country is generation of electricity, direct uses are Emuruangogolak gaining momentum in various parts of the country. Farmers Mt. Elgon Silali have for decades, used geothermal heat to dry pyrethrum Paka KENYA Korosi flowers and condense steam for drinking at Eburru while L. Baringo Nyambeni the Oserian Development Company in Naivasha is using Arus-Bogoria geothermal energy to heat 50 hectares of greenhouses of cut Kisumu Oo roses for export. A tourist hotel at Lake Bogoria is utilizing Menengai Mt. Kenya spring water at 38°C to heat a spa pool. Despite the Eburru availability and enormous potential in direct use L. Naivasha applications, little use has been made of low enthalpy fluids Olkaria Longonot in Kenya. This paper therefore discusses direct use Suswa applications and available opportunities in swimming, Ol'Esakut Nairobi bathing, balneology, agricultural, aquiculture and in Olorgesaille o residential and industrial sectors L. -

The major volcanoes in the region are located in the following States: Algeria, Cameroon, Cape Verde Islands, Chad, Comoros Island, Democratic Republic of Congo, Djibouti, Eritrea, Ethiopia, France (Reunion Island), Kenya, Madagascar, Mali, Niger, Nigeria, Rwanda, Sao Tome and Principe, Spain (Canary Islands, Madeira), Sudan, Tanzania and Uganda. The names of the concerned volcano are listed in APPENDIX K (source: Smithsonian Institution). This document is the AFI Air Traffic Management (ATM) Volcanic Ash Contingency Plan which sets out standardised guidelines and procedures for the provision of information to airlines and en-route aircraft before and during a volcanic eruption. Volcanic contamination, of which volcanic ash is the most serious, is a hazard for safe flight operations. Mitigating the hazards posed by volcanic ash in the atmosphere and/or at the aerodrome cannot be resolved in isolation but through collaborative decision-making (CDM) involving all stakeholders concerned. During an eruption volcanic contamination can reach and exceed the cruising altitudes of turbine-powered -

H. BAKER, B.Sc, F.G.S. Geologist 165^G FOREWORD The publication of the report on the geology of the area south of Magadi completes the account of the southern end of the Rift Valley as it occurs in Kenya. The Magadi area itself was described by Mr. Baker in Report No. 42 (1958). During the mapping of the continua tion of the Magadi area the discovery of some critical exposures enabled the correction of an error of succession in the lower Pleistocene rocks that had been made during the survey of the Magadi area. The area is wild and desolate, but of considerable interest scenically, with the western Rift wall a little beyond its west boundary, rugged hills of ancient rocks in the south-east and two prominent volcanoes, Lenderut and Shombole, rising from the Rift floor.
