"Carbon capture initiative at the Belchatow thermal power plant PGE signed a memorandum of understanding (MoU) with Alstom in December 2008 for the design and construction of a pilot carbon capture plant (CCP) at the latest unit of the plant.
PGE signed a grant agreement of €180m ($245m) for the installation of carbon capture, transport, and geological storage facilities in May 2010.
The project was expected to be completed by 2015, but canceled in 2013 following environmental opposition to underground storage of carbon.
If completed, it would have captured 1.8 million tonnes of CO2 a year."
I don't understand why there would be opposition to storage of carbon?
