In the Greater Paris region alone, 250,000 homes are geothermally heated, which prevents the discharge of thousands of tons of CO₂. Geothermal hot water is now considered to be a natural resource that can serve as a less expensive, better-performing alternative to fossil fuels.

However, using this eco-friendly energy raises a few technical issues.

EXPLANATION

Where does the hot water used for
geothermal energy come from?

Water is collected

deep down inside naturally hot ground-water reserves

It is run through an exchanger

that recovers its calories

It is then used to heat

buildings or supply heat to industrial sites

Finally, it is reinjected

into the place from which it was extracted

Why treat
geothermal water?

Whether it comes from a high-enthalpy well or a low- to medium-temperature well, geothermal water is highly corrosive and very scale-forming in water networks, requiring appropriate treatment.

Hot water from low- to medium-temperature wells has a particularly elevated load of bacteria and scale, which causes damage to operating facilities. Its corrosive properties complicate its use.
Water from high-enthalpy sites (over 150°C / 300°F) is even more laden, especially with sodium, limescale, lithium and lead (at levels 10 times higher than those found in seawater).

A comprehensive ODYSSEE solution

Without intervention, geothermal water is not compatible with operating infrastructure.
Knowledge of infrastructure properties allows for the optimization of its management
and the extension of system lifespans. Geothermal network maintenance relies on
a range of dedicated solutions.
