A few weeks ago, we published an item setting out details of work done by Newcastle University on dry gas scrubbing as a means of CO2 adsorption (The key starting point in any CCS process) and the particular effectiveness of the TORBED processor in industrial gas scrubbing applications. Some level of CCS is going to be an essential component of our journey to net zero. As we look over the range of scientific opportunities in front of us, implementation of dry scrubbing-based CCS solutions to complement the wet scrubbing solutions already being implemented. One of the challenges to be surmounted is the reliable availability of a sorbent which can be the means of storage as well as capture, thereby overcoming the difficulties involved in and energy required in processes to desorb CO2 from reusable sorbents and the consequent storage challenges. The answer is possibly under our feet. Olivine-(Mg, Fe)2SiO4-is widely available in the upper layers of the earth’s mantle and is natural CO2 adsorbent. Milled up and introduced to CO2-rich gas stream in an effective contacting device such as a TORBED processor, it might offer some interesting possibilities.
