...Abstract Localized corrosion poses a critical challenge for geothermal systems due to the presence of high temperatures and corrosive species such as chlorides, acid gases, and dissolved oxygen. Models that can accurately predict the risk of localized corrosion are thus essential for effective...

...Abstract In geothermal energy production, precipitation/scaling and potential plugging of wells is one of the major threats to flow assurance. Mitigation strategies should be considered at the design stage, but to do so knowledge about solubility across a relevant space of temperature, pressure...

...Electrochemical measurements Abstract Corrosion and scaling are some of the most common challenges in geothermal applications due to the complex brine chemistry combined with the high temperatures and pressures, and the gaseous components. To study mineral scaling at metallic surfaces...

...Abstract Geothermal power holds immense potential as a renewable energy source with low emissions utilizing the Earth's natural heat to generate electricity. With growing concerns over climate change and the need for sustainable energy alternatives, geothermal power can provide energy independence...

...Low pH geothermal waters can originate due to the interaction between the waters, underground rocks and gases released from the Earth’s core. Chemical elements such as sulfur from the magma can combine with oxygen to produce sulfur dioxide and thus interact with underground waters to produce acidic...

...This case study highlights the challenges facing designers of equipment required to operate in geothermal environments. It describes the failure of a non-condensable gas extraction pump at the Nga Awa Purua Power Station (NAP) which has a capacity of 140 MW. The station is located near Taupo...

... ]. The software used a database of thermodynamic properties of iron compounds that was developed from a number of different sources. The database has been proven effective for geothermal steam and brine environments in New Zealand, Philippines, Indonesia, and Japan [ 5 ], [ 6 ]. Abstract Geothermal power...

...Abstract Since geothermal wells are a feasible energy source to replace fossil fuel supply, many technologies have been developed to take advantage of geothermal energy. Nevertheless, service conditions in geothermal facilities are in many cases extreme in terms of corrosion due to the chemical...

...Abstract Over a dozen commercial and new polymer, polymer-like carbon (PLC), and diamond-like carbon (DLC) coatings originally developed for the Oil & Gas industry show promising characteristics against geothermal carbonate scales. This paper discusses the major findings of both (a) calcium...

...Abstract Over the past few years, geothermal energy production received significant attention as it is one of the renewable sources of energy and adds negligible greenhouse gases to the environment. Despite the advantages of geothermal-based energy production, it is fraught with many challenges...

...Simulated geothermal drilling test environment Table 2 shows the experimental conditions in the autoclave high temperature and pressure (HTHP) test, simulating drilling environment, with conditions used in Iceland. In geothermal drilling the cooling fluid (mud) used is commonly water based...

...The corrosion protection of a geothermal power plant encountering acid fluids can be achieved by choosing high-alloy materials, such as titanium and nickel-chromium alloys ^{7 , 8} . Although these materials offer improves performance, they also have higher cost-performance ratio...

...EXPERIMENTAL PROCEDURE Prestressed, internally heated, 50 mm diameter expansion compensator bellows, one of S32100 and one of N08825, were exposed to external contaminants as might be encountered under leak conditions or under wet insulation in a geothermal two-phase fluid, steam or brine pipeline...
