Development of a Low Temperature Geothermal Organic Rankine Cycle Standard (2013)
AuthorsTaylor, L., Krumdieck, S.show all
Low temperature geothermal is an abundant resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle is the standard process for low temperature energy conversion. Power plant prospecting, design, and, development is normally carried out by established companies. New Zealand is lacking experience in the design and manufacture of low temperature geothermal ORC plants. Experience can be gained through a thematic analysis of both successful and unsuccessful developments. A thematic analysis is a qualitative investigation that examines patterns and themes in data. This paper looks at one case study of a low temperature geothermal Organic Rankine Cycle and organizes the data into four key areas: prospecting, concept plant feasibility, detailed design, and, construction and results. Future research requires more data to validate these patterns. The outcome of this analysis will be the foundation for a low temperature geothermal design standard for the Above Ground Geothermal Allied Technologies research cooperative (AGGAT).
