Wind turbine generators: DFIGs or Rare Earth magnets?
Wind turbines can use doubly fed induction generators (DFIGs) or permanent magnet synchronous generators (PMSGs) based around Rare Earth metals. This data-file captures the trends in DFIGs vs PMSGs over time by tabulating 40 examples, as turbines have grown larger, and different wind turbine manufacturers have adopted different strategies.

Electric vehicles: motors and magnets?
This data-file assesses electric vehicle magnets, permanent magnets and the use of Rare Earth materials such as neodymium (NdFeB). 80-90% of recent EVs have used Rare Earth permanent magnets, averaging 1.5 kg per vehicle, or 7.5g/kW of drive-train power, across the data-file. But the numbers vary vastly. From 0-4 kg per vehicle. 20 vehicles from…

Magnets and permanent magnets: company screen?
The global magnet industry is fragmented across hundreds of suppliers, including 800 in Asia-Pacific. The total market is worth $20bn pa. The purpose of this data-file is to highlight a dozen leading magnet companies, including producers of permanent magnets, Rare Earth magnets (e.g., NdFeB), ferrites and other magnetic components.

Heap leaching: energy economics?
This data-file captures the energy economics of leaching in the mining industry, especially the costs of heap leaching, for the extraction of copper, nickel, gold, silver, other precious metals, uranium, and Rare Earths. The data-file allows you to stress test costs in $/ton of ore, $/ton of metal, capex, opex, chemicals costs, energy intensity and…

Metals and materials: strength and temperature resistance?
This data-file aggregates information into the strength, temperature resistance, rigidity, costs and CO2 intensities of important metals and materials. These are used in gas turbines, wind turbines, pipelines, CCS, power transmission.

Bloom Energy: solid oxide fuel cell technology?
This data-file reviews Bloom Energy’s solid oxide fuel cell technology. What surprised us most was a candid overview of degradation pathways of solid oxide fuel cells, a focus on improving the longevity of fuel cells, albeit this sometimes seems to be via heavy uses of Rare Earth metals, and increasing complexity. The patents do suggest…

Commodity prices: metals, materials and chemicals?
Annual commodity prices are tabulated in this database for 70 materials commodities; covering steel prices, other metal prices, chemicals prices, polymer prices, all with data going back to 2012. 2022 was a record year for commodities. The average material commodity traded 25% above its 10-year average and 60% of all material commodities made ten-year highs.

Capital goods market sizes: by category, by country?
This data-file tabulates globally traded capital goods market sizes, based on the values of products exported from different countries-regions. Specifically, commodity Code 84 represents machinery and mechanical appliances, worth $2.5trn pa in 2023. About half of that represents classic capital goods categories, as decomposed in the chart above. Our top five conclusions follow below.

Global trade: balance or darkness?
Global trade has been growing more adversarial. US foreign relations are also shifting. Hence this 16-page note maps 20 trade categories, across energy, materials and capital goods; in each case, breaking down global imports by source, and global exports by destination. Our top ten conclusions follow.
