Distributed low-enthalpy power solutions will revolutionise the geothermal industry. We call it micro-geothermal. Our technology picks up small temperature differences at shallow levels, turning them into meaningful electricity - ideal to power a rural village, a hotel, an airport, military base or shopping centre. Shallow holes drilled from 50 metres to 200 metres feed our highly tuned, ORC engines, which are refined to meet this challenge. Our techniques cannot be easily copied or replicated. Over a decade of research has helped tune our technology to address the limitations of ORC for power production at temperatures so low, it works almost anywhere on earth.
Viable power can be created anywhere – not just in areas of geothermal hot springs but in London, Singapore, Toulouse, the Australian outback or the African Rift. This has enormous potential to revolutionise the lives of people - from big city centres to remote areas in under-developed parts of the world. Greenstorc provides rural communities and townships in developing nations with clean, 24-hour power, and involves them in the ownership, management, sale and usage of the power facility.
Our heat-to-power technology can be powered naturally wherever volcanoes, earthquakes and warm springs are present. Water temperatures of 40°C-100°C can be used to drive our low-enthalpy devices. Drilling is generally about USD $30 per foot or USD $100 per meter. In good geothermal sites, temperatures should rise by no less than 6°C per 100 meters. A 1000m hole is considered shallow for geothermal and could yield sufficient pressure and water to generate more than a megawatt – competitive with wind, but with the bonus of 24-hour production.
We can capture low-temperature heat from shallow depths in the ground to build small-scale power plants almost anywhere, with the same technology commonly used to heat and cool buildings. These can be grouped together to build larger scale heat farms that have a smaller footprint than solar and are more reliable and cost efficient than equivalent solar and wind installations.
