Carbon Negative Technology

  1. 1. Carbon Negative Technology The Carbon Negative Solutions That Remove CO2 From The Atmosphere More companies than ever before are making commitments to be carbon neutral or even carbon negative. Earlier this year, Microsoftcommitted to going carbon negative by 2030. Swedish retailgiant IKEA made the samepromise along with a goal that all their products will be "100% circular", meaning fully reusableor recyclable. Both 'climate positive'and 'carbon negative' mean the samething: removing CO2 fromthe atmospherein order to make a positive impact on climate change. While the term carbon negative is established in the U.S., climate positive is gaining ground in Europe.

  2. 2. Achieving the challenging climate targets set out in the Paris Agreement requires more than justcutting emissions. For one thing, not all industries or sectors in society will be able to achieve net zero emissions by 2050. Itis challenging to reduce emissions in agricultureand mobility to net zero and to offsetother greenhousegas emissions like methane and nitrous oxide. So, to keep the global temperature rise to no more than 1.5 degrees higher than pre-industriallevels, the IPCC has said we mustproactively removeCO2 fromthe atmosphere. The IEA has consistently said that the global energy transition requires a portfolio of technologies and measures. Thosefor carbon removalcan be grouped into three broad categories: nature-based 'carbon sink'solutions, the enhancement of natural processes, and new technologies. Within these categories individual approaches areinterlinked in many ways and provide benefits beyond CO2 removal. Carbon Negative : Can we get there? https://oke.io/UrWoDxS Nature-based solutions One of the simplest ways wecan create carbon sinks is to stop cutting down trees and encouragereforestation and the seeding of forestin new areas. Simply put, trees absorb and store carbon but dead trees release it. Approximately 31% of the earth's land surfaceis forested, but that is down from almost46% in the pre- industrial era. Norway has ploughed more than $1 billion into the Amazon Fund, a mechanism designed to reduce emissions fromdeforestation and forestdegradation of the Amazon rainforest. Organizations likethe Rainforest Foundation also deliver concrete results across centralAfrica and Asia/Oceania. There are concerns over the potential for wildfires to destroy that carbon store, so reforestation alone isn't a silver bullet and the retention time and safeguarding arenot straightforward.

  3. 3. Enhancing natural processes The natural processes of our planet storecarbon, but we can help the process along through proactiveland management tools and techniques. Improved land management could store up to nine billion tonnes of CO₂ each year. Two such methods include the use of biochar and seaweed. Managing wasteis a major challenge for all cities. Organic wastefromparks and gardens can be turned into biochar for useas soil, which minimizes waste while establishing a new carbon sink. Researchers fromseveralNordic countries have formed the Nordic Biochar Network to spread knowledgeand experience about biochar. Researchers havefound that seaweed plays an important role in permanently moving CO2 from the atmosphereinto ocean sediments. While better managing seaweed-denseareas known to be carbon negative can help the climate crisis, increasing the amount of farmed seaweed could also help to solve the future food crisis. Itis key though to keep track off the carbon, the retention time and where it ultimately ends up. The concept of enhanced weathering also deserves wider consideration. Weathering erodes rocks over millions of years, washing theminto the oceans and solidifies CO2 in the process. Enhanced weathering is the process of pulverizing silicate rocks to bypass the slow weathering process and enjoy the benefits much faster. Enhanced weathering makes water morealkaline, helping to counter acidification, while the process can also improvecrop yields and restoredegraded soils. This can also be done in industrialprocesses by mineralizing CO2 using, for example, mafic minerals like Olivine or Basaltic rocks, buttypically 3-10 kg of rock needs to be moved around for each kg of CO2 saved. The weathering processes arealso quite slow as pointed out earlier and thus could become irrelevant for the 30-year timeframefor climate neutrality. Injecting CO2 into young basaltic rock as undertaken at the CarbFixstoragesite in Iceland shows much faster reactions and fixation, albeit used to re-inject CO2 and H2S fromgeothermal heat extraction.
  4. 4. Carbon Negative : Can we get there? https://oke.io/UrWoDxS New carbon negative technologies Finally, new technologies to remove CO2 at sourceor fromthe atmospherefor storageelsewhere are in rapid development. Carbon capture and storage(CCS) technologies can be used in conjunction with bioenergy, the burning of biomass for energy, to create a carbon negative solution. According to the IPCCthis process alonehas the potential to permanently storegigatonnes of CO2 every year, although this is reliant on sustainablebiomass availability and the full-scaleimplementation of CCS. Norway's recentannouncement of the Longship CCS projectis a major step on the road to full-scaleCCS implementation including CO2 of biogenic origin fromwaste to energy plants. Another technological solution that needs further development is the direct-air capture of CO2. This technology uses chemicals to removeCO2 fromambient air, which can be stored underground. If used in the production of materials such as plastics it could be climate neutral, but if the ultimate disposalis in a waste to energy plant with CCS, it becomes carbon negative. Further research and development is needed to bring down the costand the amount of energy needed to power the necessary infrastructurefor the technology to work at scale. Finally, an exciting new technology to indirectly remove CO2 fromthe air via seawater is also under development, which could also help to slow the alarming acidification of the oceans which are increasing at an alarming rate. Carbon Negative : Can we get there? https://oke.io/UrWoDxS The next steps
  5. 5. Of course, it is important to say that none of these carbon removaltechniques and technologies are an alternative to cutting emissions nor an excuse for slowing down other measures. But they will inevitably play an important role in a portfolio of comprehensivesolutions to the climate crisis. As part of their recent commitment to going carbon negative, Microsoftpledged to invest $1 billion over the next four years into the technologies needed to achieve such a shift. "Weunderstand that this is justa fraction of the investment needed, but our hope is that it spurs moregovernments and companies to invest in new ways as well," said a company statement. At present, such solutions experience market failure as they do not produce many other benefits besides removing CO2 from the atmosphere, obviously a common good. In order to stimulate the marketdesire, it is important that Governments and the EU speed up the research and innovation efforts into such solutions. There is no doubt that such solutions are needed, but it will take more than investment fromtechnology companies to move the needle and develop these technologies to work at-scale Carbon Negative : Can we get there? https://oke.io/UrWoDxS --------------------------------------------------------------------------
