Nature based solutions: CO2 removals in 2022?
Is the nascent market for nature based carbon offsets working? We appraised five projects in 2022, and contributed $7,700 to capture 440 tons of CO2, which is 20x our own…
Decarbonized gas: ship LNG out, take CO2 back?
Can you transport CO2 in LNG carriers? This 14-page report explores an option to decarbonize global LNG: (i) capture the CO2 from combusting natural gas (ii) liquefy it, including heat…
Liquefied CO2 carriers: CO2 shipping costs?
This model captures the costs of liquefied CO2 carriers, i.e., a large-scale marine vessel, carrying CO2 at -50ºC temperature and 6-10 bar of pressure, as part of a CCS value…
Flaring reduction: fire extinguishers?
…monetizing gas that is more than 20km from any existing infrastructure (page 8) and the other half of the challenge is in capturing small and hard-to-capture gas streams (page 9)….
Market sizing: what if CO2 abatement costs are distributed like US income?
…US CCS could achieve (note below). https://thundersaidenergy.com/2021/10/21/carbon-capture-how-big-is-the-opportunity/ High cost decarbonization opportunities that cost around $150-350/ton could find a limited market of around 60MTpa (1% of total US decarbonization) if the…
Industrial gas separation: swing producers?
…1966. Today, tens of thousands of PSA plants purify hydrogen, biogas, polymers, nitrogen/oxygen and possibly in the future, can capture CO2? This 16-page note explores the technology, costs, challenges, companies….
HJT solar: Indium summer?
…to capture more energy across the spectrum of incoming light. The higher bandgap semiconductor is amorphous Si:H. But it has low conductivity. And thus, for current to reach the electrical…
Storage tank costs: storing oil, energy, water and chemicals?
…corrosive chemicals that can require double tanks, stainless steel or specialized tank linings. Maybe $1,000/ton is fair here. Costs are also typically 3-5x higher for storing cryogenic liquids, which can…
Electric vehicle: battery life?
…battery cycle lives to capture the full range of driving behaviours (chart below). These numbers all assume that vehicle operators respect recommendations not to charge a battery beyond 80% of…
CCS: what CO2 purity for transport and disposal?
…to freeze out and plug the system. So this requires the highest purity of CCS value chains and dedicated dehydration. https://thundersaidenergy.com/2021/10/07/carbon-capture-on-ships-raising-a-sail CO2 purity for CCS will generally need to be…
