AI Technical Summary
Technical Problem
In existing technologies, the cost of using freshwater to extract hot dry rock from deep islands and reefs is high, resulting in reduced economic benefits.
Method used
By using seawater to enhance permeability, a network of fractures in a thermal reservoir is formed through seawater fracturing. Seawater is then injected into the well as a fracturing fluid to form the network. The dry hot rock is then extracted using seawater, and the seawater is recycled after power generation, thus reducing extraction costs.
Benefits of technology
It effectively reduced the cost of hot dry rock mining, solved the problem of scarce freshwater resources on remote islands and reefs, and achieved both economic efficiency and environmental friendliness in energy supply.
