absolute insanity - the new normal.
Let’s go back to the 1800s.
Let’s go back to burning rocks.
Let’s go back to more expensive energy.
Let’s go back to choking, dirty air.
Let’s go back to black lung disease.

Adding carbon removal to a waste to energy plant is a no brainer - excited about this first project with Hafslund Celsio!
Hafslund Celsio is building the world's first carbon removal retrofit at a waste-to-energy facility, enabled by a $30M offtake with Frontier buyers. Writ large, this approach could remove 400 million tons of CO2 per year by 2050. frontierclimate.com/writing/hafs...

Frontier has facilitated its first electrochemical DAC offtake with Phlair.
Phlair has the potential to deliver ultra low-cost DAC for a few reasons—one being that their approach is explicitly designed to work with cheap intermittent energy sources like solar.
