An old solution to the emission problem

A more than seven-decade-old technology is coming in the limelight on the journey to net zero

Countries and companies around the globe are turning to a more than seven-decade-old technology, which never found much favour earlier, in order to meet the net-zero goals they have committed to. This is after the belated realisation that even aggressive adoption of the current clean energy technologies will not be enough to reach those targets.
