Mission Zero Technologies, a London-based startup, has successfully initiated the first-ever Direct Air Capture (DAC) facility in the United Kingdom. Partnering with The University of Sheffield, the facility aims to trap carbon dioxide (CO2) from the atmosphere, inspired by the natural efficiency of the human lung in removing CO2 from the body.
The DAC facility, a brainchild of Mission Zero Technologies, utilizes a revolutionary ion-selective electrochemical separation process. Unlike traditional methods employing CO2 scrubbers and high-temperature processes, this organic method operates continuously, efficiently extracting CO2 and concentrating it as a pure gas. The technology boasts a 3x reduction in energy consumption compared to previous DAC methods, utilizing off-the-shelf components for enhanced accessibility.
Nicholas Chadwick, CEO of Mission Zero Technologies, expressed excitement about delivering the UK’s first DAC plant in collaboration with The University of Sheffield. He emphasized DAC as a versatile technology capable of driving both deep industrial decarbonization and permanent carbon removal.
The unique approach of Mission Zero Technologies draws inspiration from the human lungs, aiming to replicate the effortless process of CO2 removal. By avoiding the use of chemicals like hydroxides and amines, the technology pioneers a greener path towards carbon capture.
The pilot facility, designed to capture 50 tonnes of CO2 annually, further stands out for its commitment to sustainability. Solar power fuels its operations, ensuring a minimal carbon footprint in line with the objective of reducing atmospheric CO2 concentration.
From Captured Carbon to Sustainable Aviation Fuel (SAF)
While conventional carbon capture often focuses on storing carbon underground, Mission Zero Technologies takes a different route by repurposing captured carbon into valuable products. The University of Sheffield’s team of researchers will utilize the captured carbon to produce Sustainable Aviation Fuel (SAF).
Aviation, responsible for approximately two percent of global emissions, has become a critical target for carbon reduction efforts. SAF, synthetically produced and derived from captured CO2, offers a promising solution to minimize the industry’s environmental impact. Aircraft engine manufacturers such as Pratt and Whitney and Rolls Royce are already experimenting with SAF blends, envisioning futuristic engines that can run exclusively on SAF.
The UK government has ambitious plans to incorporate 10 percent SAF in all flights by the end of the decade, highlighting the growing importance of sustainable alternatives in the aviation sector.
Challenges and Skepticism
Despite the promising strides in DAC and SAF technologies, skeptics raise concerns about feasibility. Generating SAF from CO2 involves an energy-intensive process requiring additional carbon and hydrogen. While DAC and SAF initiatives operate on a scale deemed by some as too small for meaningful impact, proponents argue that these innovations represent crucial steps toward sustainable aviation and global decarbonization.
As Mission Zero Technologies pioneers a lung-inspired approach to carbon capture and sustainable fuel production, the future of aviation may find itself propelled by eco-friendly alternatives, ushering in a new era of cleaner skies and a reduced carbon footprint in the global fight against climate change.
