Gas dehydration: costs and economics?
…solid sorbents and molecular sieves. For an overview, see our note into swing adsorption. But we think the most interesting read across from our gas dehydration model is for CCS/DAC….
Direct air capture of CO2: the economics?
…solvents, which informs our numbers here. There is also a ‘dry process’ that we have reviewed using sorbents, being progressed by companies such as Climeworks. We still prefer the economics…
Air conditioning: energy consumption?
…here), which will inherently tend to become strained during hellishly hot conditions. Next-generation technologies may also improve the energy intensity of air conditioning by adsorbing water onto sorbents (see AirJoule)….
DAC companies: direct air capture screen?
…which could confer materially lower energy intensities and financial costs, using advanced sorbents, passive DAC, mineralization and electrochemical systems. Many are at the pilot stage. Emergence of DAC companies over…
Verdox: DAC technology breakthrough?
…Verdox patents that we reviewed used quinones, mostly naphthoquinones, anthraquinones (images below) and polymers of these quinones such as polyanthraquinones (cited in press articles) as electrochemically active sorbents. When a…
CCS: what CO2 purity for transport and disposal?
…of CO2 disposal, across various technologies, from straight-run amine CCS, to DAC, CO2-EOR, blue hydrogen SMRs and ATRs, oxy-combustion, potassium carbonate, other sorbents, next-gen membranes. But what CO2 purity levels…
Greenfield LNG: Does Exxon have an edge?
…ExxonMobil has leading LNG technology for extra-large trains using the APX process, modular LNG units that minimise on-site construction costs, pressure-swing absorption to remove gas-contaminants and efficient gas turbines. Opportunities…
Waste heat recovery: heat exchanger costs?
…IRR. The capex costs of heat exchangers are estimated at $200/m2 on average, but this varies between $100/m2 and $500/m2 depending on the thermal swing and corrosiveness of fluid streams…
Gas treatment: an overview?
…order of magnitude more expensive, especially for early-stage biological processes being explored. Other technologies in the data-file include wet-scrubbing using solvents, membranes, metal oxide guards, swing absorption and water removal….
Industrial materials: thermodynamic efficiency?
…continue screening them in our CCS research, but for now, the two notes below capture what we are looking for, to get excited by next-gen membranes and adsorbents. https://thundersaidenergy.com/2023/03/30/membranes-for-carbon-capture-separation-anxiety/ https://thundersaidenergy.com/2023/06/22/industrial-gas-separation-swing-producers/…
