Carbon Capture and Storage Watts, Robin; Narayan, Srikanth
On December 12, 2015, Canada and 194 other countries signed the Paris accord, an ambitious agreement to fight climate change. This agreement called for a concerted effort to limit the global average temperature rise to well below 2°C and pursue further efforts to limit the increase to 1.5°C. (Canada, 2016) This implies that the remaining carbon budget available at our disposal is extremely limited, and that the world must reduce greenhouse gas emissions at a rapid pace. But even then, we may not meet the target without the aid of the so-called negative emissions. Advanced technologies are being employed to reduce emissions in hard-to-abate sectors, such as cement and power, and also to sequester CO2 already present in the atmosphere. High on the list is carbon capture, use, and storage (CCUS), the term for a family of technologies and techniques that capture CO2 and use or store it to prevent its release into the atmosphere. Through direct air capture (DAC) or bioenergy with carbon capture and storage (BECCS), CCUS can effectively bring down CO2 concentrations in the atmosphere, helping to achieve the need of the hour - negative emissions. In some cases, the captured CO2 can be used to create products ranging from cement to synthetic fuels. (Biniek, Henderson, Rogers, & Santoni, 2020) In their endeavour to meet the climate goals, the UBC Vancouver campus has achieved aggressive GHG reductions (38% from 2007 to 2018) and are committed to look for pathways to achieve zero and eventually negative emissions. However, UBC won’t be able to completely reduce its reliance on fossil fuels due to research experiments and Bunsen burners. Also, to be noted is that the burning of purchased RNG (renewable natural gas) also has a biogenic CO2 component. Hence some sort of negative carbon accounting will be necessary if UBC is to fully reach its goal of zero GHG emissions by 2050.
