Turquoise hydrogen from methane pyrolysis: economics?
Turquoise hydrogen is produced by thermal decomposition of methane at high temperatures, from 600-1,200◦C. Costs can beat green hydrogen. This data-file quantifies the economics (in $/kg), how to generate 10% IRRs, possible capex costs, and remaining challenges for commercialization.

Transformer costs: the economics?
Transformer costs must typically run at $8/kVA to earn a 10% IRR constructing a new transformer manufacturing facility, across capex costs, materials costs, specialized labor costs, and all built-up from first principles in this economic model. We have also screened 25 leading companies in transformer manufacturing.

Global coal supply-demand: outlook in energy transition?
Global coal use likely hit a new all-time peak of 8.8GTpa in 2024, of which 7.6GTpa is thermal coal and 1.1GTpa is metallurgical. The largest consumers are China (5GTpa), India (1.3GTpa), other Asia (1.2GTpa), Europe (0.4GTpa) and the US (0.4GTpa). This model presents our forecasts for global coal supply-demand from 1990 to 2050.

Nickel production: the economics?
This model captures the economics of producing battery-grade nickel (e.g., Class I, nickel sulphate) at a metallurgical processing facility. Marginal cost is likely around $11,500/ton in order to generate a 10% IRR, in a process emitting 14 tons of CO2 per ton of product. Numbers vary.

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?
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 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 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?
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 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.
