Research commissioned
We have recently commissioned two pieces of research to develop the process.
The first part addresses the Energy Balance of the process – how much energy is required to drive the process? While we know how much energy is required to thermally decompose (calcine) limestone into lime and carbon dioxide (this is after all what people in the lime industry do every day), we need to change the process slightly, so that we are able to capture pure carbon dioxide, which is much easier to sequester. Through contacts from this website I have been in touch with the German Lime Association who have been able to provide some very useful and encouraging information on current energy requirements and indications on what the requirements for the altered system might be. At the same time as we are gathering empirical data, we are also creating a computer model of the energy requirements of the altered calcination system – this work is being undertaken by Dr Panos Parris and Dr George Manos both at University College London. They will be reporting out in the first week in September.
The second piece of research is on the environmental impact of adding the lime to seawater. This work is being carried out by Professor Gideon Henderson, Dr Heather Bouman and Dr Ros Rickaby, all at the Department of Earth Sciences at the University of Oxford. This research will be a preliminary assessment of the effects of the process and will identify further areas of research to determine whether, and how, this process can be conducted in an environmentally beneficial way. They will be reporting out in the middle of September.
As part of the open source approach we are taking, we will publish the research results on the website as soon as we receive them
