Advancements in Carbon Capture and Utilisation (CCU) Technology Pave the Way for Novel Applications From  Ethylene, to Polymers, Syngas and Even Diamonds 

Tough competition of outstanding innovations unveiled at the CO₂-based  Fuels and Chemicals Conference 2024 

Hürth, 3 April 2024: This year’s nominees for the innovation award “Best CO2-Utilisation 2024” prove  that CO2 innovations can be used to produce syngas, polymers, organic fatty acids, ethylene, renewable  isopropyl alcohol (IPA), but also aviation fuels and diamonds. 

The award is one of the highlights of the CO2-based Fuels and Chemicals Conference and puts a  spotlight on innovative products and technologies in the field of Carbon Capture and Utilisation (CCU).  An expert jury and the conference advisory board and sponsors selected six promising nominees among  the interesting submissions received. Those will have the chance to present their CO2 innovation to a  broad international audience at Maternushaus, Cologne (Germany) and online on the 17th of April 2024. 

Honouring six CO₂ pioneers 

D-CRBN – Plasma-based CO2 Conversion – (BE) 

D-CRBN is a three-year-old CCU spin-off from the University of Antwerp. The company has established  a proprietary modular and scalable plasma technology capable of splitting the CO2 molecule into CO,  all in a fully electrified, gaseous phase, without solvents or catalysts. The CO is then turned into added value chemicals, such as e-fuels, organic acids, polymers, etc. that are used as feedstocks for the  chemical, petrochemical, maritime, and metallurgical industries among others. 

Dioxycle – Ethylene Producing Electrolyser – (FR) 
GIG Karasek– ECO2Cell – Pioneering Modular Syngas Production – (AT) 

ECO2Cell is a cutting-edge, modular plant for producing syngas through low-temperature  electrochemical conversion of CO2. This innovative technology platform efficiently converts CO2 into  valuable chemicals and fuels, promoting a circular economy. Its modular design ensures scalability and  adaptability to various industrial applications, offering a sustainable and cost-effective solution for CO2  emission challenges.

The Sky Mining Company – Skydiamond – (UK) 

Skydiamond, the world’s first carbon-negative diamond, is mined from the sky. The Sky Mining Company  created an alternative to the destructive act of land mining. Skydiamonds are planet-positive, certified,  and chemically identical to the timeless diamonds. This carbon-capture innovation is a patented and  bespoke biological process operating out of the English countryside using only four ingredients;  rainwater, solar and wind power and of course, atmospheric carbon, making these the most sustainable  diamonds in the world.

Twelve – E-Jet®– (US)  

E-Jet® fuel, Twelve’s sustainable aviation fuel (SAF) made from CO2, is produced with only three inputs  – water, renewable electricity, and CO2. E-Jet® fuel was tested and certified by the U.S. Air Force in  2021, drop-in ready for use in existing aircraft, made to ASTM D7566 specifications, the same  performance standard as fossil-based jet fuel. All with up to 90 % lower lifecycle emissions and fewer  sulfur dioxide (SO2), nitrogen oxides (NOx), and other particulate emissions.

University of Bologna – RAPCOR – (IT) 

The RAPCOR concept aims to convert flue gas carbon into renewable isopropyl alcohol (IPA), serving  as a versatile fuel, energy carrier, hydrogen carrier, or commodity chemical. RAPCOR approach uses  microbial mixed culture (MMC, consisting of anaerobic homoacetogens) supported on a peculiar char based sparger reactor to reduce bicarbonate with renewable hydrogen, thus obtaining high  concentration (>60 g/L) acetate, which is ketonised and hydrogenated to IPA. This process works at  mild pressure and temperature and allows to overcome most of the limitations of existing Power-To Fuel pathways.

The CO2-based Fuels and Chemicals Conference 2024 

The CO2-based Fuels and Chemicals Conference has developed into a unique meeting and networking  place for the entire CCU and Power-to-X industry and its customers. This year’s edition will take place  from 17–18 April, in Cologne, Germany as a hybrid event. Just like in previous years, this event will be 

Dioxycle is pioneering a breakthrough carbon electrolysis technology that converts industrial emissions  into sustainable ethylene using just renewable electricity and water. As a result, Dioxycle can produce  carbon-neutral ethylene cost competitively with the fossil pathway, providing an economically attractive  pathway to defossilise many industrial and commercial sectors. Ethylene is the world’s most used  organic chemical, finding application in key everyday products such as textile fibres, plastics, and  construction materials. showcasing the latest and most important developments in the fast-growing field of CCU with plenty of  opportunities to network. 

Smart innovations will be making a major contribution to the replacement of fossil-based products in the  industry and transport sectors, playing a crucial role in defossilising Europe.
