Electrasteel: renewable steel breakthrough?
…since 2012. 70% of steel is made in blast furnaces and basic oxygen furnaces, in a pathway that emits over 2 tons of CO2 per ton of finished steel (model…
Wind turbine generators: DFIGs or Rare Earth magnets?
…across all of the leading wind turbine manufacturers. We have tabulated the model, manufacturer, country, capacity (MW), year introduced (YYYY), rpm, gear system, typical voltages (kV, where available), generator system…
Cryogenic air separation: company screen?
…Uptime and utilization are crucial to the economics of air separation units (model here). Hence this means that some of the largest and most experienced equipment manufacturers in the space…
Topsoe: autothermal reforming technology?
…have lower rates of CO2 capture (e.g., KBR technology) or lower uptime and resiliency. Our updated model of blue hydrogen costs integrates some of the considerations from this data-file and…
Adiabatic flame temperature: hydrogen, methane and oil products?
This data-file is a simple model calculating adiabatic flame temperatures from first principles. At an idealized, 100% stoichiometric ratio, the adiabatic flame temperature for natural gas is 1,960ºC, hydrogen burns…
Alterra Energy: technology review?
…of scavengers may add costs above those considered in our simple plastic pyrolysis economic model. However, five years on from first looking at this technology, we also see increasing value…
Pressure swing adsorption: energy economics?
…reforming tail gases, and for CH4/CO2 separations in biogas. We have also played around with some more complex models such as Sips and Toth models (chart below). But mainly, the…
Industrial gas separation: swing producers?
…how much gas adsorbs onto a zeolite, we cover the basic theory of Langmuir Isotherms (pages 5-6), and more advanced models such as the Sips model (page 7). Zeolites and…
Industrial materials: thermodynamic efficiency?
…this is $13/ton. This is not a high energy use or a high energy cost. The challenge today is that technically ready DAC processes are only around 5% efficient (model…
Global decarbonization: speeding up or slowing down?
…China, India, Brazil and Africa (pages 12-13). Reforest and reinvest looks like a promising economic development model, which could uplift the GDP of 47 emerging world countries by 6-60% while…
