The first week of November sees Shell officially open its first major carbon capture and storage (CCS) facility, the Quest project. It is in Alberta, Canada and will capture and store about one million tonnes of carbon dioxide per annum. Construction commenced back in September 2012 when the Final Investment Decision (FID) was taken and the plant started up and began operating for the first time in September of this year, just three years later. It is one of only a handful of fully integrated carbon capture and storage facilities operating globally. There are now many facilities that capture CO2 but mainly linked to Enhanced Oil Recovery which provides an income source for these projects. Quest has dedicated CO2 storage, developed in an area some 65 kms from the capture site at a depth of about 2 kms.
The Quest income source is not based on EOR; it has been able to take advantage of the government implemented carbon price that prevails within Alberta. Although the current carbon pricing mechanism has an effective ceiling of $15 per tonne CO2 which isn’t sufficient for CCS, let alone a first of its kind, it nevertheless provides a valuable incentive income to operate the facility which has been built on the back of two substantial capital grants from the Provincial and Federal governments respectively. A supplementary mechanism also in place in Alberta provide credits related to the carbon price mechanism for the early years of a CCS project, providing additional operating revenue for any new facility.
Canada, as it turns out, has become a global leader in CCS. The Quest facility is the second major project to be started up in Canada is as many years, with the Saskpower Boundary Dam project commencing operations this time last year.
As noted, Quest will capture and store approximately one million tonnes of carbon dioxide per annum. It demonstrates how quickly and efficiently large scale CO2 management can be implemented once the fiscal conditions are in place. Quest, which is relatively small in scale for an industry that is used to managing gas processing and transport in the hundreds of millions to billions of tonnes globally, demonstrates both the need for continued expansion of the CCS industry and the importance of carbon pricing policy to drive it forward. This single facility far surpasses the largest solar PV facilities operating around the world in terms of CO2 management. Take for example the Desert Sunlight Solar Farm in California, currently the fourth largest solar PV power station in the world. According to First Solar, it displaces 300,000 tonnes of CO2 annually, less than a third of that captured and permanently stored by Quest.
A key difference though is the use of the word displace. Alternative energy projects don’t directly manage CO2, they generate energy without CO2 emissions. But, as I have noted in previous postings and in my first book, the release of fossil carbon to the atmosphere is more a function of energy prices and resource availability. This means that even when a project like Desert Sunlight operates, the CO2 it notionally displaces may still be released at some other location or at some other time, depending on long term energy prices and extraction economics. There is no doubt that the CO2 is not being emitted right now in California, but that doesn’t necessarily resolve the problem. Quest, by contrast, directly manages the CO2 from fossil fuel extraction.
The requirement to provide alternative energy (i.e. without CO2 emissions) needs to grow, but we shouldn’t imagine that such action, by itself, will fully resolve the climate issue. That will come through the application of carbon pricing mechanisms by governments, driving the further expansion of both the alternative energy and CCS industries as a result.
