Energy Recovery Inc: pressure exchanger technology?
Pressure exchangers transfer energy from a high-pressure fluid stream to a low-pressure fluid stream, and can save up to 60% input energy. Energy Recovery Inc is a leading provider of pressure exchangers, especially for the desalination industry, and increasingly for refrigeration, air conditioners, heat pump and industrial applications. Our technology review finds a moat.

Acetylene: production costs?
Acetylene production costs are broken down in this data-file, estimated at $1,425/ton for a 10% IRR on a petrochemical facility that partially oxidizes the methane molecule. CO2 intensity is over 3 kg/kg. Up to 12MTpa of acetylene is produced globally for welding and as a petrochemical building block.

AirJoule: Metal Organic Framework HVAC breakthrough?
Montana Technologies is developing AirJoule, an HVAC technology that uses metal organic frameworks, to lower the energy costs of air conditioning by 50-75%. The company is going public via SPAC and targeting first revenues in 2024. Our AirJoule technology review finds strong rationale, technical details and challenges.

Demand shifting: electrical flexibility by industry?
Demand shifting flexes electrical loads in a power grid, to smooth volatility and absorb more renewables. This database scores technical potential and economical potential of different electricity-consuming processes to shift demand, across materials, manufacturing, industrial heat, transportation, utilities, residential HVAC and commercial loads.

Polyester: production process?
Polyester is the most produced textile fiber on planet Earth. Of the world’s 8GTpa of oil and gas production, 80MTpa, or 1% ends up as PET, via eleven chemical processing stages that span naphtha-reforming, BTX separation into paraxylene, oxidation to PTA, plus ethane cracking, ethylene oxide and ethylene glycol. This data file covers the polyester…

Pressure swing adsorption: energy economics?
Pressure swing adsorption purifies gases according to their differing tendencies to adsorb onto adsorbents under pressure. Pressure swing adsorption costs $0.1/kg when separating pure hydrogen from reformers, and $2-3/mcf when separating bio-methane from biogas. Our cost breakdowns include capex, opex, maintenance, zeolite replacement, compression power and CO2 costs.

Carbon capture and storage: research conclusions?
Carbon capture and storage (CCS) prevents CO2 from entering the atmosphere. Options include the amine process, blue hydrogen, novel combustion technologies and cutting edge sorbents and membranes. Total CCS costs range from $80-130/ton, while blue value chains seem to be accelerating rapidly in the US. This article summarizes the top conclusions from our carbon capture…

Sulphur recovery units: Claus process economics?
This data-file captures the economics of producing sulphur from H2S via the Claus process, yielding an important input for phosphate fertilizers and metals. Cash costs are $40-60/ton and marginal costs are $100/ton. CO2 intensity is low at 0.1 tons/ton. Data-file explores shortages in energy transition?

Aspen Aerogels: insulation breakthrough?
Aerogels have thermal conductivities that are 50-80% below conventional insulators. Target markets include preventing thermal runaway in electric vehicle batteries and cryogenic industrial processes (e.g., LNG). This data-file notes some challenges, using our usual patent review framework.

Hydrogen: lost in transportation?
Transporting hydrogen will be more challenging than any other energy commodity ever commercialised. This 19-page note reviews the costs and complexities of cryogenic trucks, pipelines and chemical carriers (e.g., ammonia). Midstream costs will be 2-10x higher than natural gas, while up to 50% of hydrogen’s embedded energy may be lost in transit.
