  • Lithium from brines: the economics?

    Lithium from brines: the economics?

    This data-file approximates the costs of battery-grade lithium from brines, via traditional salars the emerging technology of direct lithium extraction. Costs are c40-60% lower than mined lithium in ($/ton of lithium carbonate equivalent). CO2 intensity is 50-80% lower (in kg/kg).

  • Recycling: a global overview of energy savings?

    Recycling: a global overview of energy savings?

    1GTpa of material is recycled globally, across steel, paper, glass, plastics and other metals. On average, 35% of these materials are produced from recycled feeds, saving 70% of the energy and CO2, with upside in the Energy Transition.

  • Mining: crushing, grinding and comminution costs?

    Mining: crushing, grinding and comminution costs?

    Mining crushing-grinding costs are typically $10/ton of ore, breaking 3-10cm rubble into 30-100 micron powders. Capex averages $20/Tpa and energy cost averages 20kWh/ton.

  • Bio-coke: energy economics?

    Bio-coke: energy economics?

    Bio-coke is a substitute for coal-coke in steel-making and other smelting operations. We model it will cost c$450/ton, c50% more than coal-coke, but saves 2 – 2.5 tons/ton of CO2. Abatement costs can be as low as $70/ton. Although not always, and there are comparability issues.

  • Cost of North Sea gas: project economics?

    Cost of North Sea gas: project economics?

    Marginal costs of a HPHT project in the UK North Sea are captured via modeling Shell’s 40kboed Jackdaw project, FID’ed in 2022. A $7/mcf marginal cost results mostly from high hurdle rates associated with project complexity. CO2 intensity has been lowered to c14kg/boe, we think.

  • Electrowinning: costs and energy economics?

    Electrowinning: costs and energy economics?

    Electrowinning costs and energy economics are built up in this data-file. A charge of $900/ton is required to earn a 10% IRR on a $3,000/kTpa plant with a median energy consumption of 2-3 MWH/ton. Although this will vary metal by metal.

  • Nitric acid: production costs?

    Nitric acid: production costs?

    Global production of nitric acid is 60MTpa, in a $25bn pa market, spanning c500 production facilities. This data-file estimates a marginal cost of $350/ton HNO3 and a CO2 intensity averaging 1.8 tons/ton. There are feedback loops where gas shortages could result in fertilizer and metal shortages.

  • Hydrofluoric acid: the economics?

    Hydrofluoric acid: the economics?

    Hydrogen fluoride is a crucial commodity chemical. This model captures its production from acid-grade fluorspar and sulfuric acid. We think marginal costs are around $1,850/ton, in order to earn a 10% IRR on a production facility costing $4,000/Tpa, while the fully loaded CO2 intensity is around 0.75 tons/ton.

  • Global energy demand: by region and through 2050?

    Global energy demand: by region and through 2050?

    This model captures global energy demand by region through 2050, rising from 70,000 TWH in 2019-22 to 120,000 MWH in 2050. Demand rises c2% pa. Energy use per global person rises at 1% pa from 9.3 MWH pp pa to 12.6 MWH pp pa. Meeting human civilization’s energy needs is crucial to the energy transition.

  • Liquefied CO2 carriers: CO2 shipping costs?

    Liquefied CO2 carriers: CO2 shipping costs?

    This model captures the economics of a CO2 carrier, i.e., a large marine vessel, carrying liquefied CO2, at -50ยบC temperature and 6-10 bar pressure, for CCS. A good rule of thumb is seaborne CO2 shipping costs are $8/ton/1,000-miles. Shipping rates of $100k/day yield a 10% IRR on a c$150M tanker.
