Carbon Lock Solutions
Unlocking Oceans to Lock Down Carbon
Remove...
> Atmospheric carbon dioxide
enhancing ocean capacity for
CO2 drawdown & mineral lock
> Ocean acidification from CO2 emissions forcing by
rebalancing alkalinity
Restore...
> CO2 ppm to viable norms
> Long term global temperatures
> Ocean pH to sustain a thriving & productive marine biota
> Ocean - Atmosphere balance
> Overall health of the planet!
Revalue...
> Natural & engineered solutions
where process synergies bring
efficiency gains to climate
resortation
> By-product chains in
H2, minerals, water streams
The Problem
> Atmospheric CO2 > 420 ppm
> CO2 now > 1.5X pre-industrial mean
> CO2 never higher in over 800 000 yrs
> CO2 traps heat & forces global warming
> CO2 acidifies oceans - harms marine life
The CLock Ticks
> Earth now nears the +1.5 oC target
above the IPCC 1850-1900 mean
as set in the 2016 Paris Agreement
> 6 of 9 Earth boundaries are crossed
> Climate tipping points approach
The Opportunity
> Decarbonisation critical but not enough
Carbon Dioxide Removal (CDR)
> @ 6-8 Gigatonnes / year (IPCC)
> Needed to meet net zero by 2050
> But only 0.002 Gt CDR in "novel" tech
> A potential 2000X scaling gap remains
The Natural Value
> Ocean acidity 1.3X > pre-industrial
> pH @ 7th Earth boundary crossing
> Causes mineral based marine life loss
> CLock restores local alkalinity
> Boosts CO2 sequesting marine life
The Transition Value
> CLock tech can supply
Green H2 & Minerals
> For building, pharma, farming, efuels
> Potential for LCOH @ < $3 / kgH2
> Potential for LCOC @ < $130 / tCO2
> First draw...
CO2 + CO3(2-) + H2O > 2HCO3(-)
> @ high pH Henry's Law acts large...
> So pseudo-1st order @ pH 10
> But bimolecular @ pH 9 when Hp(CO2 )~ [CO3(2-)]
