These are: the USA (North America), Chile (South America), Spain (Europe), South Africa (Africa) and China (Asia).<\/p>\n\n\n\n<p>The research follows&nbsp;<a href=\"https:\/\/www.gov.uk\/government\/statistical-data-sets\/sustainable-aviation-fuel-saf-mandate-statistics-data-tables#section\">recent statistics from the UK\u2019s SAF mandate<\/a>, which show the majority of SAF in the UK is made from used cooking oil.&nbsp;<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Professor Meihong Wang, Professor of Energy Systems at the University of Sheffield, who led the research, said:&nbsp;<\/strong>\u201cDecarbonising the aviation industry is key to slowing global warming and achieving net zero. SAF has emerged as a promising solution to meet energy needs while reducing greenhouse gas emissions, as it works in existing engines, potentially allowing for sustainable air travel without major mechanical changes to aeroplanes. However, a major challenge in switching to SAF is ensuring that we have enough feedstock to produce the huge amount of fuel that the industry needs and also making the fuel in a way that doesn\u2019t require fossil fuels.<\/p>\n\n\n\n<p>\u201cThe process we have proposed has the potential to address key challenges in scaling up SAF. It\u2019s a renewable energy-powered way of capturing CO<sub>2<\/sub>&nbsp;from air and making SAF that is cost-effective and can be scaled to industrial levels. It also reduces electricity consumption in the production process and can fit within a circular economy.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p>The solar-driven SAF technique was developed in collaboration with researchers from the East China University of Science and Technology. It improves on an existing proposed way of making SAF called Direct Air Capture and CO<sub>2<\/sub>Utilisation (DACCU), which is currently in the research and development phase.<\/p>\n\n\n\n<p>This existing DACCU method captures CO<sub>2<\/sub>&nbsp;from the air and combines it with hydrogen, similar to the proposal led by Sheffield, however it heats the chemicals using a fossil fuel &#8211; natural gas &#8211; a process which the Sheffield-led team says would prevent SAF from being a truly sustainable fuel.&nbsp;<\/p>\n\n\n\n<p>The researchers from Sheffield and China have shown in their study that replacing the fossil fuel with concreted solar energy is capable of providing the intense heat needed to create the chemical reactions to produce SAF. It could also cost less than existing DACCU pathways &#8211; projections estimate US$4.62 per kg compared to US$ 5.6 per kg.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Professor Wang added:<\/strong>&nbsp;\u201cThe innovation lies in a hydrogen-fluidised calciner. This is a specialised reactor that uses a field of mirrors to focus sunlight, eliminating the need for onsite fossil fuel combustion. By using hydrogen to circulate the carbon particles, the system also streamlines production as it serves as the medium to circulate the carbon particles while simultaneously providing the essential feedstock for fuel synthesis.<\/p>\n\n\n\n<p>\u201cThis dual-purpose design allows us to bypass traditional, complex steps like syngas production and CO<sub>2<\/sub> purification, resulting in a much more streamlined and cost-effective production cycle. By converting atmospheric carbon into SAF directly onsite, we transform CO<sub>2<\/sub> from a waste product into a valuable resource, fostering a circular economy that eliminates the need for the expensive pipeline networks and geological reservoirs required by traditional carbon capture and storage.\u201d<\/p>\n<\/blockquote>\n\n\n\n<div style=\"height:17px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><em>The study was conducted by researchers from the University of Sheffield, University of Manchester and East China University of Science and Technology.
