Professor Mercedes Maroto-Valer, the UK's Decarbonisation Champion, shares innovative ideas on turning CO2 into something useful. She discusses the need to rethink carbon dioxide, capturing and utilizing CO2, 3D printing smart rocks for real-time data, developing sustainable aviation fuel, and the urgent need to tackle climate change with realistic optimism.
Carbon dioxide can be harnessed in useful ways by converting it into fuel or safely storing it away.
Decarbonisation involves finding applications for excess carbon dioxide while recognizing the usefulness of carbon in various industries and products.
Deep dives
Carbon as a Dirty Word
In the current climate, carbon has gained a negative connotation due to its association with greenhouse gases and climate change. However, Mercedes Morota Valle, Director of the Research Centre for Carbon Solutions at Heriot Wat University, wants to change that perception. She believes that carbon is not inherently bad and can be harnessed in useful ways. By capturing carbon dioxide from the atmosphere and converting it into fuel or safely storing it away, she aims to make carbon a climate-saving compound.
Decarbonisation and Defossilisation
Mercedes Morota Valle emphasizes the importance of decarbonisation, which involves taking excess carbon dioxide from the atmosphere or point sources such as heavy energy industries and finding applications for it. However, she argues that completely getting rid of carbon is not the goal. Instead, she advocates for defossilisation, getting rid of carbon derived from fossil fuels, while recognizing the usefulness and significance of carbon in various industries and products.
Making CO2 Useful
Mercedes Morota Valle's research focuses on finding innovative ways to utilize carbon dioxide. She mentions an intriguing process called mineralization, where CO2 is transformed into a solid mineral by reacting it with specific minerals. This process locks away CO2 and can be applied to road construction or as a permanent storage solution. Additionally, she discusses her work in developing environmentally sustainable aviation fuel that consumes CO2 during production, offering a potential solution to decarbonize the aviation sector.
How do you solve a problem like CO2?
As the curtain closes on the world’s most important climate summit, we talk to a scientist who was at COP 28 and is working to solve our carbon dioxide problem.
Professor Mercedes Maroto-Valer thinks saving the planet is still Mission Possible - but key to success is turning the climate-busting gas, CO2, into something useful. And as Director of the Research Centre for Carbon Solutions at Heriot-Watt University and the UK’s Decarbonisation Champion, she has lots of innovative ideas on how to do this.
She also has a great climate-themed suggestion for what you should say when someone asks your age…
