World geothermal power generation nearing eruption
With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth’s heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total ...

Case Study - 2.0 MW Nominal Geothermal Power Plant
Lake Naivasha, Kenya – 2007 Under a contract signed in June 2006 with Oserian, Geothermal Development Associates (GDA) agreed to design, manufacture, inspect, test, pack, and ship a 2 MW nominal geothermal steam turbine generator and related power plant auxiliary components from Reno, Nevada, USA to the Oserian flower-growing facility near Lake Naivasha, Kenya. GDA will provide technical ...

Heat as a by–product or sub–product of CO2 storage in mafic and ultramafic rocks
Since carbonates are at a lower energy state than free CO2, storage through carbonation of silicate rocks is thermodynamically favoured and proceeds spontaneously by releasing heat. In an in–situ CO2 injection site, the heat released in these exothermic reactions can be exploited in a geothermal power–plant, effectively contributing toward the economic viability of the storage process. Our ...

Waste Heat Recovery`s Role in ESG Strategy
What is ESG? Environmental, social, and governance (ESG) refers to a company’s set of standards in relation to sustainability, human and social capital, leadership, and compliance. These factors play an increasingly large role in business decisions as shareholders are becoming more concerned with how an organization’s (primarily) eco-social practices will affect long-term growth in a ...

Geothermal Power Approaches 12,000 Megawatts Worldwide
In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal’s best year since the ...

A Brief Look at Sustainable Energy Solutions
There’s been a lot of discussion around sustainable energy solutions over recent years. Governments and businesses are taking initiatives to undo the damage done from years of unabated use of fossil fuels. People are now desperate to adopt sustainable sources of energy. The governments and big businesses have jumped on board, too, as they realize that traditional energy sources aren’t ...

Electricity production from geothermal sources by binary system; choosing secondary fluids
Because of the increasing prices of fossil fuels and the demand for cleaner electricity production, many sources of renewable energy have been proposed. Although Turkey has the seventh highest geothermal potential in the world and the second highest in Europe, electricity generation from geothermal energy is quite low. The purpose of this article is to search for the possibility of electrical ...

Exergoeconomic evaluation of a geothermal power plant
In this study, exergy and exergoeconomic analyses of the Dora II geothermal power plant (DGPP) with 9.5 MW net power output are carried out by using real thermodynamic and cost data. The exergetic efficiency of this plant is calculated to be 29.6%. The highest exergy destruction rate among the DGPP components occurs in the cooling towers followed by the turbines, vaporisers, preheaters and pumps. ...

Case Study - Aluto Langano Power Plant Rehabilitation
Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

Fossil Fuel Development in the Arctic is a Bad Investment
Even master chess players can miss a great move when they have been primed to look for a different one. To explore this phenomenon, researchers tracked master chess players’ eye movements when given chessboards with different layouts. With the first board, players could reach checkmate using a familiar move. When given the second chessboard, the players' eyes kept looking at the pieces ...
