Revolutionizing the Energy Industry: The Rise of Advanced Geothermal Systems
The Earth’s internal heat is a virtually unlimited source of energy, and advanced geothermal systems are harnessing this power to transform the way we generate electricity.
### Unlocking the Potential of Geothermal Energy
Geothermal energy has been around for decades, but recent advancements in technology have made it a more viable and cost-effective option. In 2020, geothermal power accounted for 13% of the world’s renewable energy mix, with a total installed capacity of 12.2 GW.
### How Advanced Geothermal Systems Work
Advanced geothermal systems (AGS) use Enhanced Geothermal Systems (EGS) technology to tap into hot rock formations at depths of up to 5 kilometers. This is done by drilling a well and injecting water to extract the heat, which is then used to produce steam. The steam drives a turbine, generating electricity.
### Benefits of Advanced Geothermal Systems
AGS offers several advantages over traditional geothermal systems. For one, it can access geothermal resources in areas previously thought to be uneconomic. Additionally, AGS can be used in a wide range of environments, from hot dry rock to high-temperature hydrothermal systems.
### Global Deployment of Advanced Geothermal Systems
Countries like the United States, Australia, and Indonesia are already reaping the benefits of AGS. In the United States, the Department of Energy has invested millions in AGS research and development, with several pilot projects underway. Australia’s Barmedman project is expected to be the world’s largest AGS facility when completed.
### The Future of Advanced Geothermal Systems
As the world shifts towards a low-carbon future, AGS is poised to play a significant role. With its high capacity factor, low greenhouse gas emissions, and potential to reduce fossil fuel use, AGS is an attractive option for countries looking to decarbonize their energy sectors. As technology continues to evolve, we can expect to see even more innovative applications of AGS in the years to come.
