Climate change dictates that we need to reduce carbon emissions to net zero or even to net negative emissions as fast as possible. There has been much talk of carbon capture and storage. However just pumping carbon dioxide into old oil and gas wells seems both a waste of a potentially valuable resource and a rather insecure method of storage. I’ve long argued that carbon capture and utilization was a much better path to explore. There are many methods of doing this, from very well known and old to the most innovative high tech fields of research.
Photosynthesis takes carbon dioxide out of the atmosphere. Using high quality timbers like oak and teak in construction locks this carbon up in the fabric of a building, potentially for many centuries. Algae grow rapidly and are potentially the basis of a whole range of sustainable renewable energy and chemical industries. In 2009 Scottish Bioenergy built a very interesting algal bioreactor at the Glenturret Whiskey Distillery in Crieff, turning industrial waste into energy and a range of useful products, including high protein fish food. Using photosynthesis to capture carbon in timber, algae and other useful plant materials has a powerful positive role to play in carbon sequestration and in modern industrial innovation.
Carbon can also be directly captured from the atmosphere, or from flue gases, and used in a whole range of other useful products, from cement to plastics. A few years ago I got very excited at the prospect of carbon negative cements, which have great potential but which unfortunately cannot yet compete on price with ordinary Portland cement. Currently there is a lot of interest in making the plastics industry more sustainable. One of my favourite examples of this is Econic Technologies.
Econic Technologies is an amazing UK start-up. It was founded in 2011 by Professor Charlotte Williams to use carbon dioxide as a feedstock in the production of polymers. These are used in an extraordinarily wide range of products from trainers to mattresses, coatings and adhesives to appliances and in construction. The process they use will help reduce the energy use and ecological footprint of this whole range of industrial products. Econic Technologies, like MeshPower that I blogged about last week, was started by people from Imperial Collage in London. They have now grown due to investment from Imperial Innovations, Jetstream Capital, Norner and most recently Woodford Investment Management. This has allowed them to hire more staff and to open a new Application Development site at Alderley Park in Cheshire. This small start up seems to be growing well, and the technologies they have developed may have a huge role in helping reduce the pollution caused by the global chemical industry. I wish them every success.
