Hydrogen is a clean-burning gas that could be used to replace fossil fuels in planes, trains, trucks, factories and even in home heating. Another key reason for developing CCUS is to unlock the potential of hydrogen. One of the key reasons CCUS is necessary is because heavy industry – fertiliser producers, steel mills and cement makers – would be difficult and expensive to adapt to run on cleaner energy. Read more Why do we need carbon capture ?Īccording to the IEA, CCUS projects could reduce global carbon dioxide emissions by almost a fifth and reduce the cost of tackling the climate crisis by 70%. In the UK, early-stage projects are being developed near the Humber estuary and in Aberdeen, the capital of the North Sea oil and gas industry. The watchdog says there must be many more to keep carbon emissions from heating the world to more than 1.5C above pre-industrialised levels. Although CCUS has had a slow start, 30 new projects have been agreed in the past three years, the International Energy Agency says. The early forerunners are in the US, Canada, Norway and China. There are about 20 CCUS projects operating commercially, nowhere near enough to clean up the world’s carbon emissions. Where is carbon capture technology being used ? But some could be used to help make plastics, grow greenhouse plants, or even carbonate fizzy drinks. Most carbon dioxide will be injected deep underground – where fossil fuel gas comes from in the first place – to be stored where it cannot contribute to the climate crisis. The gas can then be piped to locations where it can be used or stored. The first step is to fit factory chimneys with solvent filters, which trap carbon emissions before they escape. This refers to a chain of different technologies that can keep the carbon dioxide produced by major factories and power plants from reaching the atmosphere and contributing to global heating.
