CO2 from natural sources shows potential for commercial use (Ecofys)
A new study by Dutch renewable energy consultant Ecofys, commissioned by the European Bank for Reconstruction and Development (EBRD), analysed prefeasibility assessments performed for both urea production and greenhouses (urea is an important ingredient in many fertilizers). The study concluded that CO2 may be applied usefully either to enhance urea production (if a new facility could be realized close to existing geothermal capacity) or in greenhouses.
The use of CO2 from geothermal power plants (GPPs) for these purposes would lead to efficiency improvements (in the case of urea yield boosting) or may avoid fossil fuel combustion to produce CO2 (as in greenhouses).
