![]() ![]() Not only does this finding represent a significant and novel discovery in the field of chemistry, researchers say, but it also helps scientists understand more about which types of compounds might be better-or worse-at capturing carbon out of the air. By using electrochemical techniques to change their molecular structures, the researchers find that quinones can indeed bind with and capture carbon in a controlled fashion. Scientists revealed the results of their experiments on a family of compounds known as quinones in a new paper published recently in the journal Energy Advances. National Grid has said the carbon emissions from UK’s electricity system could turn negative by as early as 2033 if it used carbon capture technology alongside more renewable energy to reach its climate goals.Oana Luca, an assistant professor of chemistry, is one of the study's co-authors. Large energy companies, including National Grid, Drax and the Norwegian oil company Equinor, have since begun work on a full-scale CCUS project in the Humber area, and a handful of UK universities have pursued a separate project in Aberdeen. Three years later, ministers returned to the table with less money and a new idea: to use CCUS for heavy industry instead. They stumbled in 2015 after the government abandoned a £1bn scheme to set up a carbon capture project alongside coal-fired power plants because of cost concerns. How are the UK’s carbon capture ambitions going? Hydrogen could still be made by splitting water molecules into hydrogen and oxygen gases using a renewable energy powered electrolyser machine, but this would be far more expensive. But without carbon capture being used to produce hydrogen from fossil fuel gas, carbon emissions would be released into the atmosphere. 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.

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. ![]()
