#Forbes: The Rise Of #CarbonTech – #CO2 Finds Market Value
Exciting things are happening in the world of carbon capture. A new category of companies are coming to market that are using technological innovation to turn excess CO2 into useful, marketable products. They are calling themselves “CarbonTech” or “Carbon to Value” and proposing that carbon waste can be turned into products of real value.
According to the 2018 report by the Intergovernmental Panel on Climate Change (IPCC), humanity will need to reduce its global carbon budget significantly in the next 10 to 14 years to avoid the existential threat of severe and catastrophic climate change. Carbon buildup in the atmosphere over the past hundred years is already causing tangible impacts such as the recent flooding in Mozambique, the California fires and the severe storms which have afflicted major portions of the US.
There are fundamentally three ways to reduce the carbon budget to meet the IPCC goals.
One pathway to reducing the carbon budget, already in practice worldwide, is to lower the demand for fossil fuels in the energy, transportation and agricultural sectors while simultaneously bringing electricity, food and good transportation to the developing world. This requires changes to many entrenched systems, which move slowly—policy, business/industry and agriculture are all sectors that need modifications to business-as-usual. All will require technological and business model innovation. Thanks to real progress in energy efficiency and renewable energy cost reductions, these changes are happening, albeit slowly.
A less viable, but often mentioned pathway would be geological engineering of the atmosphere on an enormous and unprecedented scale. This would involve dumping particulate matter or water vapor into the stratosphere to reflect the sun’s rays back upward, likely causing unforeseen, unintended consequences.
A third, and very promising, pathway would be to focus on increasing the rate of removal of man-made CO2. The issue is of such importance that former Secretary of Energy, Dr. Ernest Moniz, launched a study called “Clearing the Air” at Climate Week in NYC.
Trees, soil and oceans do soak up CO2, but do so at a rate that, while sufficient for naturally occurring CO2, cannot keep up with humanity’s insatiable appetite for creating CO2. For the past 150 years, the excess has been dumped into the atmosphere as waste and remains there for up to 200 years.
The first pathway, energy efficiency and resource conservation, works slowly. The second, geoengineering, poses risks not worth pursuing. The third, CO2 capture and utilization, offers the opportunity to manufacture high value products out of CO2 waste, creating a market value for carbon, which policy makers have been largely unable to do. It is possible to create opportunity out of past errors.
In the past, efforts to remove carbon from the atmosphere focused on storing carbon in underground caverns at enormous expense. Without a reliable carbon pricing mechanism, this became a money sink as much as a carbon sink. Recently, next-generation carbon removal processes are beginning to see the light of day, and creeping out from the caverns. Simply put, the intention of the prize is to reward technologies that capture excess CO2 to make high-value products that command a market price. Loosely framed, the technologies form three categories—those that create materials for the cement and concrete aggregate industries, those that create fuels, plastics and chemicals and those that create durable carbon products such as carbon fiber, carbon black and carbon nanotubes. In addition to the companies vying for the prize, there are now companies with similar technologies appearing at both the academic and commercialization level.
