What Is Carbon Capture?

Global temperatures are increasing. Fact.

Over the past 200 years the average global temperatures have increased by 1℃. Temperature rises of between 3-6℃ by 2100 are projected if we continue on our current path. Higher temperatures will destabilise vital natural processes that humans and the natural world rely on to maintain a delicate balance.

Ultimately the Earth itself will be fine, but life on it is in serious trouble if we continue as we are

Man-made Climate Change

The cause of this temperature rise is an increase in greenhouse gases present in the Earth’s atmosphere. Our atmosphere. And this significant greenhouse gas rise is due to human activity.

The largest greenhouse gas by volume is carbon dioxide. Transport, heating, industrial processes, energy production, agriculture, all produce large amounts of carbon dioxide and whilst great efforts are underway to decarbonise these sectors it will not be enough.

Carbon, however, will still need to be removed from the atmosphere.

The Carbon Cycle

The carbon cycle is the natural process by which the chemical element carbon is constantly being passed between carbon sinks.

Carbon can exist in many different places on the planet.

  • On land as biomass (e.g. vegetation and animals), in soil as organic matter or rocks,
  • In the oceans as biomass, decayed organic matter, or it dissolves into water,
  • In the atmosphere as carbon dioxide,
  • Deep underground as fossilised carbon, some of which are extracted as fossil fuels.

Overtime carbon will move between these different sinks in a number of different ways. Some of these processes can take seconds (fossil fuels into atmosphere), some happens on an annual basis (from the atmosphere to biomass), and some occur over millions of years (biomass to fossil fuels).

Unfortunately our dependency on fossil fuels is destabilising this balance far more carbon dioxide is being emitted into the atmosphere than can be removed by existing natural processes.

Natural Carbon Capture

The good news is that we can work with Nature to boost capture carbon and store it in natural sinks, either in the soil or in the biomass of trees and plants.

There are a wide range of range of plants and ecosystems that are able to capture carbon.

Plants, trees, bacteria, fungi, soil dwelling creatures, and animals great and small all play their part in complex webs that, in some cases, we know relatively little about. Crucially, healthy ecosystems are able to turbocharging the carbon capturing process.

Fuelled primarily by photosynthesis atmospheric carbon dioxide can be turned it into stable solid forms and be stored either in tree trunks or under our feet as ‘soil carbon’
