  • Electrasteel: renewable steel breakthrough?

    Electrasteel: renewable steel breakthrough?

    Electra is developing an electrochemical refining process, to convert iron ore into high purity iron, and ultimately into steel, using only renewable electricity. It has raised c$100M, gained high-profile backers, and is working towards a test plant. This 9-page note reviews an exceptionally detailed patent, finds clear innovations, but also some remaining risks and cost…

  • Direct reduced iron: costs and projects?

    Direct reduced iron: costs and projects?

    Direct reduced iron (DRI) is produced by reacting iron ore with H2-CO syngas, fueled by natural gas, in over 150 facilities worldwide. Direct reduction iron costs $300/ton, consuming 3,000kWh/ton of energy and CO2 intensity of 0.6 tons/ton. The process can be decarbonized via low-carbon hydrogen in the syngas, as the world strives towards decarbonized steel.

  • Silica producers: screen of leading companies?

    Silica producers: screen of leading companies?

    Highly pure silica sand, with well over 95% SiO2 content and less than 0.6% iron oxide, is an important resource used in making glass, metal foundries, “proppant” for hydraulic fracturing in the oil and gas industry and making high-grade silicon (for chips and PV silicon). The market is 350MTpa. This data-file is a screen of…

  • Costs of hydrogen from coal gasification?

    Costs of hydrogen from coal gasification?

    What are the costs of hydrogen from coal gasification? This model looks line-by-line, across different plant configurations, aggregating data from technical papers. Black hydrogen costs $1-2/kg. But CO2 intensity is very high, as much as 25 tons/ton. It can possibly be decarbonized resulting in semi-clean hydrogen costing c$2.5/kg.

  • Nexwafe: PV silicon breakthrough?

    Nexwafe: PV silicon breakthrough?

    Nexwafe is growing standalone silicon wafers on mono-crystalline seed wafers, with no need to slice ingots. It should improve solar efficiency, materials intensity and CO2 intensity. Our technology review found 60 patent filings and can partly de-risk growth ambitions.

  • Sulphur recovery units: Claus process economics?

    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?

  • Copper: the economics?

    Copper: the economics?

    The economic cost of copper production is build up from first princples in this model, from mine, to concentrator, to smelter to 99.99% pure copper cathodes. Our base case is $7.5/kg copper cathode, with 4 tons/ton CO2 intensity, after starting from an 0.57% ore grade. Numbers vary sharply and can be stress-tested in the data-file.
