geoengineering explained: the benefits and challenges of bioenergy with carbon capture and sequestration

The production of bioenergy with carbon capture and sequestration is considered a form of carbon dioxide removal (CDR). The process begins by growing biomass, burning it to create energy and finally capturing and sequestering the carbon dioxide created in the process. Negative CO2 emissions are generated by combining bio-energy production [biomass fuel power stations, pulp mills and biofuel plants] with carbon capture and storage technology, allowing carbon dioxide to be captured from the atmosphere and remitted back underground. 

Table of Contents Toggle BENEFITS	CHALLENGES
Can be fueled by any non-fossilized material of biological origin Encourages the use of renewable energy sources Provides opportunities for intersectoral collaborations and partnership development	Dependent on the cost of carbon emissions and the prices must be high enough for the process to be economically viable Unproven technology that is expensive to develop. Can only be applied to biomass to yield “negative emission” energy A large number of operations are necessary in order to achieve results
