PART 1Executive Overview
1Definition

Enhanced Geothermal Systems (EGS) involve drilling deep into the earth's crust and creating a reservoir in hot but previously unconnected rock formations to generate electricity through enhanced heat extraction.

SPECULATIVE
2Problem It Solves

Overcoming limitations of traditional geothermal systems by accessing deeper, more widespread geothermal resources that are not naturally connected to the surface.

3Lifecycle / Journey Stage

PART 2Technical & Manufacturing
4How It Works

EGS involves drilling wells deep into the Earth, fracturing the hot rock formation to create interconnected fractures, injecting water or another fluid under high pressure, circulating it through the fractured rock to extract heat, and then using this heated fluid to drive a turbine for power generation.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves specialized drilling equipment, fracturing tools, and heat-resistant materials. The wells require robust construction techniques to withstand high pressure and temperatures.

7Build Process

EGS projects involve site selection, drilling, reservoir creation through hydraulic fracturing, well completion, fluid circulation setup, and power plant installation and operation.
