Combining biomass with Carbon Dioxide Capture & Storage could result in an annual global potential of up to 10 gigatonnes of negative CO2 emissions in the year 2050. This is one of the main findings of a study commissioned by IEA Greenhouse Gas R&D Programme to the global energy consultancy company Ecofys. Compared to the almost 31 gigatonnes of global energy-related CO2 emissions in 2010, this represents a huge CO2 emissions reduction potential.
Feeding biomass to energy conversion processes for electricity or biofuel production with subsequent capture and storage of CO2 from these sources – Bio-CCS in short – results in a negative greenhouse gas balance. “The combination actually removes CO2 from the atmosphere,” says Joris Koornneef from Ecofys. “The biomass extracts CO2 from the atmosphere during photosynthesis and the CCS takes out the CO2 released in the energy conversion process”.
