Geothermal systems in Indonesia - Influence on the corrosion resistance of stainless steel materials
(2014)
The growth in a global demand for energy, as well as the awareness of a significant climate change, have evolved a very strong incentive for utilizing and expanding the use of clean and renewable energy resources. Geothermal energy is considered as one of a few alternatives ideal for replacing conventional sources due to its consistency and reliability, and is receiving ever more attention. However, geothermal Systems are found to be the most aggressive natural environments in terms of corrosion. High temperature and pressure conditions, as well as the existence of almost an entire periodic System of elements in form of corrosive salts, present a major threat to the integrity of the construction material. Therefore, in order to achieve a safer and continuous energy production, and increase the competitiveness of geothermal energy on the world scene, a comprehensive assessment of the materials suitability is of high importance for operators and vendors. Finally, thäs would lead to an inoreased lifespan of the power plant, as well as its economic profit, due to the reduced maintenance costs.
