Carbon Dioxide Removal

April 29, 2016

It is common knowledge that climate change mitigation is a global effort. More and more technologies are currently emerging in order to mitigate the world’s rising carbon emissions. Around the world, governments are instilling awareness in their efforts to aid in mitigating carbon dioxide emissions. Renewable energies are given more attention. Wind and solar energy in the Philippines are being firmly incorporated to its peoples as an alternative energy source.

Geoengineering the Planet: Carbon Dioxide Removal Methods

Carbon sequestration and on-site carbon capture can very well be the most sensible approach to removing direct carbon emissions. The technology for capturing carbon dioxide from the air may very well be deployed as soon as it is developed. Air extraction technology does not need to interfere with other approaches to the issue of rising carbon emissions.

Carbon dioxide removal methods are processes and technologies that aim to reduce the level of carbon dioxide in the atmosphere. These methods are engineered to remove the carbon dioxide present in the atmosphere, as well as develop processes to use the harvested carbon dioxide as a source of renewable energy. Biochar, bio-energy with carbon capture and storage, direct air capture, ocean fertilization, and enhanced weathering are methods currently in development that have since made a difference in advancements to remove carbon dioxide from the atmosphere. While these methods are further pushed forward through geoengineering, research, and developing technologies, the world’s accumulated carbon emissions are still much too high for these methods to have a major impact in climate change mitigation.

Progress in the Industry: Start-Up Companies Aimed at Climate Change Mitigation

In mid to late 2000s, start up companies have pushed to refine and research their technologies in order to aid in reducing the carbon dioxide present in the atmosphere. Companies such as Carbon Engineering, Global Thermostat, and Climeworks aim to eventually build enough plants to remove carbon dioxide from the air in order to aid in climate change mitigation. These start up companies aim for a hypothetical future wherein carbon dioxide will be harvested from the sky as a source of renewable energy and transformed into low-carbon fuels. At present, carbon dioxide uses are limited.

Funding Climate Change

There is little to no market for carbon dioxide. Funding, too, is an issue. If these companies do push for a meaningful climate solution, then industrial plants designed for direct air capture of carbon dioxide will need a large scale removal system. Start ups devoted to climate change mitigation are in search for funding in hopes of advancing their technologies, and while governments still need to gear up in order to fully integrate carbon dioxide sequestration in their respective countries, start ups like Carbon Engineering, Global Thermostat, and Climeworks turn to private sectors as their source of funding. Carbon Engineering, for example, is partially funded by Bill Gates, while Climeworks turn to demonstration projects funded by German automobile manufacturer Audi.

More and more governments are integrating other forms of renewable energy such as wind and solar in order to fully integrate its people in the awareness that there is a definite need for carbon dioxide sequestration. Solar energy in the Philippines have already been integrated in the country’s energy program through Net Metering. Some methods of carbon dioxide removal are underdeveloped at present, needing more research to develop a proper cost assessment. Climate change mitigation is truly a big effort that needs all the help that it can get, through research, development, and the economic sector.
