- Negative emissions technologies remove CO2 from the atmosphere and store it or convert it to fuel.
- In addition to capturing carbon, Carbon Engineering also converts stored carbon into a fuel that can be used by everyday vehicles.
- The ability to profit from carbon capture and conversion will surely help make these kinds of technologies more cost-effective.
To hit the international goal of keeping global warming below 2 degrees Celsius this century, reducing emissions and using renewable energies probably won’t be enough. That’s why people are becoming increasingly interested in negative emissions technologies, which suck CO2 out of the atmosphere and store it underground or convert it into carbon-neutral fuel. These processes have been too costly to implement on a large scale, however.
But that might change soon: Carbon Engineering Ltd, a Canada-based company that’s been running a pilot carbon-capture program since 2015, just raised enough money to build its first commercial-scale negative-emissions facility. The company says its systems can now remove CO2 from the atmosphere at a rate of under $100 per tonne — what’s long been considered the benchmark for negative-emissions technology…
