Role of CO in low to medium enthalpy geothermal systems in the Central Betic Cordillera (Spain).

There is growing interest in geothermal energy, which is considered as an efficient energy solution to mitigate rising atmospheric CO. Besides known high enthalpy geothermal systems, increasing attention is paid to low temperature geothermal systems, as they are suitable for local use. Although geothermal production seems to be an environmentally advantageous renewable energy, it might result in significant CO emissions.
