The US DOE has announced a new initiative, entitled the Carbon Negative Shot, that aims to remove gigatons of atmospheric carbon dioxide (CO2) and store it for less than $100/tonne of net CO2-equivalent.
As part of its carbon dioxide removal (CDR) strategy, the US Government sees the expansion of this plan as a key part of achieving net-zero emissions by 2050.
Two of the most crucial aspects of fighting the climate crisis revolve around costs and CDR technology deployment, said Jennifer M. Granholm, US Secretary of Energy.
She added, “With our Carbon Negative Shot, we can help remove the greenhouse gases already warming our planet and affecting our health – positioning America as a net-zero leader and creating good-paying jobs for a transitioning clean energy workforce.”
It’s intended for the strategy to be paired with other sustainable innovations such as hydrogen, battery storage, renewables and decarbonised fossil energy.
CDR is defined as a range of approaches that capture CO2 before permanently and safely storing it in geological reservoirs, such as carbon capture, utilisation and storage (CCUS/CCS). To combat rising CO2 levels, it’s estimated that CDR will need to be deployed at the gigatons scale.
Increased funding will provide a faster rate of development and subsequent deployment, according to the US DOE.
In addition to reducing costs and promoting gigatonne-scale removal., the US Government has defined ‘performance elements’ that will be met by the Carbon Negative Shot technologies. These include a ‘robust’ accounting of lifecycle emissions and high-quality durable storage with costs demonstrated for monitoring, reporting and verification for at least 100 years.
