Using the Earth's inexhaustible heat Deep Geothermal.
Net zero carbon Heat from geothermal energy.
With its hot brine, the geology of the Upper Rhine Valley offers ideal conditions to extract natural geothermal heat and provide electricity. The hot brine is brought from subsurface reservoirs to the surface and is used to generate renewable energy. Vulcan’s geothermal power plant “Natürlich Insheim” has been reliably supplying thousands of households with climate-neutral electricity from renewable energy since 2012.
Advantages of Geothermal energy.
According to the German Federal Association for Renewable Energy, more than 50% of Germany’s energy is needed for heat. By using geothermal renewable energy, Germany and Europe can generate renewable and therefore net zero carbon heating and cooling energy, drastically reducing Germany’s reliance on imports, and making municipalities more self-sufficient.
In contrast to fossil fuels, electricity and heat from geothermal energy are carbon neutral.
Geothermal energy is available at all times, regardless of the weather and time of day.
Geothermal energy is available locally and is independent of imports.
How it works District heating with geothermal energy.
The hot brine is brought from subsurface reservoirs up to the surface and used to produce heat and electricity. Heat and electricity are then fed into the grids on site and the brine used is then returned to its natural reservoir in a closed-loop system. Carbon neutral cooling energy can also be produced from this heat in a decentralised process.
Increasing renewable energy production More wells, more geothermal energy.
- There are currently 36 geothermal plants operating in Germany, 42 active projects (c. 84 wells), and the Federal Government is targeting to reach new 100 projects by 2030.
- Vulcan owns an existing geothermal renewable energy plant with over 10 years of successful production, supplying approximately 8,000 households with renewable power.
- Phase One will utilise Vulcan’s existing operational capacity, and increase geothermal renewable energy production:
- Insheim: 4.2MW power capacity.
- Additional total planned generation capacity: 33MW power capacity, 30MW heat capacity.
“Safe, reliable and renewable energy from deep geothermal energy.”
How does Vulcan find the right location?
Vulcan investigates the subsurface to a depth of several thousand meters using sound waves triggered by brief vibrations. We do this to find suitable sites to bring brine to the surface and extract the contained lithium using no fossil fuels.
This method is called “3D Seismic”. To find out more about the topic click the link below.
