UK HPHT gas fields: marginal cost?
This data-file captures the marginal cost of developing new gas fields in the UK North Sea and in Europe more broadly, by modelling the Jackdaw HPHT project costs. Shell took…
Cyanide production: the economics?
This data-file captures the cost of producing cyanide — hydrogen cyanide as a chemical intermediate and sodium cyanide as a crucial input to the gold-silver mining industry. Marginal costs are…
Green hydrogen: can electrolysers run off renewables?
…(pages 11-13). Economic implications are spelled out on page 14. As a rule of thumb, adding a 5% pa decline rate to a base case electrolyser model might raise the…
Froth flotation: the economics?
…capex of flotation processes (in $/Tpa) and energy costs (in kWh/ton). Generally, this is one of the least capex-intensive and energy-intensive processes across all of our models. The economics, by…
Battery degradation: causes, effects & implications?
…modelling parameters — e.g., a 3-4% decline rate and a 2-3 year shorter lifespan — can obliterate a 10% IRR on a grid-scale battery. Conversely, optimizing the lifespan and functioning…
Heating-melting: how much energy is needed?
…as the Einstein photo-electron model. But we can ignore all of this for now. (3) Heating a material makes it hotter. We all use this principle every day. For example,…
Agilyx: plastic recycling breakthrough?
…YE21. Its commercial model is to license IP for categorizing thousands of different types of post-consumer plastics (on a royalty basis per kg), license its conversion technology for subsequent pre-processing…
Energy costs of energy transition?
…achieve from a period of energy surplus. You can stress-test numbers in this simple model. $449.00 – Purchase Checkout Added to cart We want to achieve an energy transition, by ramping wind…
Ethylene vinyl acetate: production costs?
Ethylene vinyl acetate is produced by reacting ethylene with vinyl acetate monomer. This data-file estimates ethylene vinyl acetate production costs, with a marginal cost between $1,500-2,000/ton, and a total embedded…
Bioleaching: case studies and examples?
…of integrated mining-smelting operation. Avoiding smelting also avoids around 2 tons/ton of CO2 emissions, which is also around a 50% reduction (model here). The technology is mature. This data-file tabulates…
