Global gas turbines by region and over time?
Global gas turbine additions averaged 50 GW pa over the decade from 2015-2024, of which the US was 20%, Europe was 10%, Asia was 50%, LatAm was 10% and Africa was 10%. Yet global gas turbine additions could double to 100 GW pa in 2025-30. This data-file estimates global gas turbine capacity by region and…

Radioactivity of materials: energy, Rare Earths and nuclear?
This data-file captures the radioactivity of materials: ranging from 10Bq/kg in sea-water, to 100Bq/kg in humans, to 300Bq/kg in Brazil nuts (the most radioactivity food), to 1,000Bq/kg in coal ash, 2,000Bq/kg in copper tailings, 0.5-1MBq/kg in Rare Earth concentrates and tailings, to 4M Bq/kg in uranium ore, 0.2 bn Bq/kg in nuclear fuel and 10-100…

Average home sizes: living space per person?
Average home sizes matter for overall residential energy demand, heating and cooling demand. Hence the purpose of this data-file is to aggregate average home sizes by country, then translate the data into living space per capita. A good rule of thumb is that each $1k pp pa of GDP translates one-for-one into 1m2 pp pa…

Silicon carbide: production costs?
This data-file captures the costs of producing different grades of silicon carbide: from materials grade SiC ($1,500/ton marginal cost, 5 tons/ton CO2 intensity) through to SiC wafers that are used in the electronics industry ($30M/ton, 200 tons/ton?). SiC semiconductor remains opaque.

Energy needed to produce steam: enthalpy and entropy data?
This data-file quantifies the energy needed to produce steam, for industrial heat, chemicals, CCS plants and hydrogen reforming? As rules of thumb, low pressure saturated steam at 100◦C requires 2.6 GJ/ton (720kWh/ton), medium pressure dry steam at 6-bar and 300◦C requires 3 GJ/ton (830kWh/ton) and super-critical steam at 250-bar and 600◦C requires 4 GJ/ton (1,150kWh/ton).

Lithium ion batteries: energy density?
Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy densities doubling to 500Wh/kg in the 2030s, trebling to 750 Wh/kg by the 2040s, and the best possible energy densities are around 1,250 Wh/kg. This…

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.

EV incentives: vehicle taxes by country?
Vehicle taxes by country are tabulated in this data-file, based on vehicles’ pre-tax prices, tailpipe emissions, weight, engine size and power. They range from sub-10% of the cost of the underlying vehicle in the US, through to 150% in Norway, and above 100% in Netherlands, Denmark and France. What implications for EV adoption?

Howmet: turbine blade breakthroughs?
Howmet is an engineered metals company, and the world’s #1 supplier of blades and vanes for jet engines and gas turbines. It has claimed an edge in direct-casting cooling channels (rather than drilling them) and bond coats that improve the adherence of Thermal Barrier Coatings. Our Howmet gas turbine technology review found support for these…

Duck curves: US power price duckiness over time?
In solar-heavy grids, power prices trough around mid-day, then ramp up rapidly as the sunset. This price distribution over time is known as the duck curve. US power prices are getting 25-30% more ducky each year, based on some forms of measurement. Power prices are clearly linked to the instantaneous share of wind/solar in grids.
