In 2016 three Icelandic Power Companies and two Governmental Agencies formed a Working Group for the development of an assessment tool to measure geothermal sustainability performance; Geothermal Sustainability Assessment Protocol, GSAP. Background: The International Hydropower Association, IHA, introduced in 2010 a multi stakeholder Sustainability Assessment Protocol, HSAP, now applied worldwide, to assess key sustainability factors of Projects, social, environmental and economic. Representatives from IHA, Governments, Finance and NGOs prepared the Protocol. The aim is to measure, guide and improve performance for sustainability topics. Iceland actively participated in the preparation of HSAP. The GSAP Working Group took on to transform this widely accepted HSAP tool to geothermal application. duke electric orlando Modifications are kept to a minimum to maintain as possible existing consensus. A Draft GSAP is now prepared and successfully tested for the Preparation Stage of Theistareykir 90 MWe and the Operation Stage of Hellisheidi 300 MWe /130 MWth.

The presentation will focus on the importance of gathering and centralizing information and documentation for the purposes of developing an understanding of how geothermal resources can best be developed. Furthermore, the presentation points out how such centralized databases can help governments understand how to attract investors and developers that are interested in exploring and exploiting geothermal resources. gas 2015 Such centralized databases will also assist countries in the important task of strengthening legal frameworks to secure national interests and the sustainable utilization of geothermal resources. Finally, it is of critical importance for the industry that developers must meet similar requirements and follow similar regulations in the different countries in which they intend to explore and/or develop geothermal resources. This can best be achieved with the gathering and public disclosure of information. Co-operation among industry leadership is necessary for such a centralized database to be achievable.

Tanzania is endowed with enormous geothermal resources which exist in the two arms of the Great East African Rift valley that transverse the country from north to south. The Government of Tanzania is determined to develop and utilize this sustainable domestic resource for generation of power and direct uses to support its fast-growing economy.

The presentation covers deliberate actions taken by them towards the development of the geothermal and harnessing the resource, particularly creation of the State Owned Entity (TGDC) for spearheading the geothermal resources development, establishment of enabling environment through formulation of appropriate legal and regulatory framework and streamlining the institution set up. In addition, the covers the status of selected geothermal flagship projects which are being implemented and mobilization of funds for test drilling. Finally, the presentation dwells on the establishment of essential local capacity both organizational and institutional that is required to support the geothermal development, exploitation and utilization.

Djibouti is a relatively small country with a population of less than 1 M, but located in a key position in eastern Africa, in a close vicinity with Arabia, well deserved by marine routes of the Red Sea and Gulf of Aden, ensuring the link between the Mediterranean and the Indian Ocean parts of the world. gas pain in chest It acts as the major port for its neighbour Ethiopia worth 100 M inhabitants.

In terms of energy, it has for long relied upon imported fuels. However, considering the global climate issue – hitting the region with increasing draughts – and despite its moderate contribution to Greenhouse Gas Emissions, the Government of Djibouti defined a “Vision 2035” in which an objective of 100% renewable energy production was defined. This implies to rely upon the various natural resources available including Wind, Solar and Geothermal.

The present meeting concerns this last sector, which is of major importance as Djibouti benefits from an exceptional location, at the intersection of the Gulf of Aden, Red Sea and East African Rift systems. This provides very high heat flow, with magmatic and hydrothermal manifestations at the surface indicating potential geothermal resources. gas prices under a dollar However, despite geothermal exploration initiated more than 45 years ago, no production is yet available. This is the reason why the President of the Republic of Djibouti decided in 2014 to establish a specialized public entity called ODDEG (for Djiboutian Office for the Development of Geothermal Energy), which is hosting the present meeting.

Since ODDEG was created, it was staffed, provided with large office facilities and a significant budget. gas natural ODDEG developed a strategy, a pluri-annual work plan and a procedure manual. A data bank was also established with a description of more than 20 identified geothermal sites in Djibouti. Besides Djibouti’s state budget, ODDEG also benefited from the help of foreign donor agencies, particularly from Japan, Iceland, Germany and USA.

The growing demand for lithium has created an immense opportunity for its recovery from produced brines. Traditionally, lithium is recovered from mining or brine evaporation with the latter requiring vast evaporation ponds, months of processing time and has low recovery efficiency. Large strides have been made in the development of selective adsorbents for lithium and other metals but their use is constrained by competing ions that must be removed in pre-treatment. We have developed a combined water treatment and metal recovery technology that overcomes these challenges and can do can operate at temperatures up to 500 °C. The pre-treatment system relies on a unique ultrafiltration approach that promotes fouling of a replaceable skin layer. wd gaster theory The layer itself is composed of highly charged materials that perform a coagulating function, enhancing the efficiency of the filtration system and making it a preferable option to the use of warm or hot lime softeners, after filters and other technologies typically seen in thermal industries. The system removes silica, magnesium, iron and other metals often to concentrations that are below method detection limits. Other scale forming ions such as calcium are reduced 40-70% to levels that do not interfere with lithium recovery. Lower concentrations are feasible but not required in our applications. The selective ion-sieves developed for lithium recovery function in a similar fashion, capturing lithium within the crystalline structure of the ion sieve within a simple column design. I will review the technology, provide an overview of lithium recovery from brines and provide a summary of a geothermal project where we have proven the technology and are moving to commercial deployment in 2018.

Ethiopia is located in the Horn of Africa, central part of the East Africa Rift valley System. Ethiopia, due to its position crossed by East African Rift Valley System (EARS), exhibits all the conditions for the development of economically exploitable geothermal systems. gas mask drawing Starting from the 70s, several geothermal prospects were studied at different levels of knowledge in relation to their characteristics.

About 23 sites are identified for potential geothermal resource development along with the Ethipian Rift Valley System. Despite the high geothermal potential of the Ethiopian Rift Valley system, only one site (Aluto Geothermal field with about 7.3 MW installed capacity) was developed in 1990s as a pilot geothermal power plant project. Studies conducted at various levels indicate that Ethiopia can develop more than 10,000MW from its abundantly available geothermal resources.

In fact, Ethiopia has also huge hydroelectric potential and currently its main energy source is from hydropower with some contribution from other sources (wind, diesel, bagas and geothermal). gas national average 2008 Recognizing the need for energy mix and diversify the energy source, the government gave due attention to develop the geothermal resource for electric generation and other direct uses to realize the country’s development goals.

Aluto and Alalobad geothermal fields are being developed under the Geothermal Sector Development Program (GSDP). The GSDP is designed to drill about 22 exploration and production wells to confirm the resource for generating electricity in the order of 70 MW at Aluto field and 4 exploration wells at Alalobad with aim of generating about 20 MW. The GSDP is funded by the World Bank (major financer), Government of Iceland and Government of Japan. The government of Japan is further considering for financing the power plant construction in two phases based the findings of the initial exploratory drilling operations at Aluto Geothermal field.
