The European Union is actively encouraging development of CCS or carbon capture and sequestration technologies. The goal is to find a way to strip CO2 emissions from energy production, especially coal-fired power plants, and safely sequester (bury) the stuff deep underground.
The EU ran a contest, with more than a quarter-million Euros up for grabs, looking for viable CCS technologies. Unfortunately none of the competitors met the requirements and no winner was declared.
Effective CCS options are considered a prerequisite for the future of coal energy, particularly Germany's reversion from nuclear to coal.
