"Let’s start with why we want to capture carbon dioxide: CO2is the gas most responsible for globalwarming. The level of CO2measured in our atmosphere is at the highest level in recorded history andcan stay there for millennia. Carbon capture technologies exist but can be expensive to deploy. Thechallenge is finding what works and doing it cheaply."

"This study suggests simultaneous multiple energy productions and CO2 storage can be realized by olivine weathering process when using a CO2-rich hydrothermal condition."

"A few months ago, I questioned a claim that planting trees could solve climate change. According to some scientists, reforestation “is by far the cheapest solution that has ever been proposed,” and for $300 billion it could sequester 200 gigatons of carbon (GtC, or 733 GtCO2). Many media outlets swooned, but the assertions were weak if not incorrect. Indeed, just this week, Science — the original outlet — published four scathing critiques of the underlying scientific paper."

"There is more consensus on what solutions are effective than there appears to be."
