Warning consumes energy from CO2 collection technology

Although it works to collect CO2, cut greenhouse gas emissions, technology can consume one quarter of global energy by 2100.

A study recently published in Nature Communications points out the energy-consuming concerns of CO2 collection technology (DAC) . This is a technology that directly collects CO2 from the atmosphere in the atmosphere for use or storage in pure form. This technology has been applied in 7 projects in some European countries such as the US, Canada, Switzerland on an industrial scale to produce clean fuels and fuels.

According to Carbon Engineering's report, after deploying this technology to the business model since 2009, the amount of CO2 collected can be up to 1 ton of CO2 per day. If installing 3,000 DAC factories, the global temperature could be reduced by 1.5-2 degrees Celsius compared to pre-industrial times, contributing to solving global warming.

However, the researchers are concerned, increasing the scale and scope of operation of specific DAC technology, increasing by 30% / year with the scale of 30GTCO2 / year, equivalent to the construction of 3,000 DAC factories. effective in reducing pollution and regenerating energy or will consume more global energy to be able to operate DAC plants.

Professor Nico Bauer at the Potsdam Climate Impact Research Institute (PIK), also does not believe that carbon removal can neutralize all future emissions by a huge amount of carbon-fossil fuel still is located underground.

According to Professor Massimo Tavoni, director of the European Institute of Economics and Environment (EIEE), despite many challenges in scaling up, it is undeniable that the importance of DAC technology in significantly reducing the amount Industrial emissions.

The United Nations Conference on Climate Change 2015 calls on each region and country in addition to DAC technology development, there must be policies to reduce emissions, minimize the negative impact of people on Climate Change.
