Advanced Conductors versus ACSR: costs and companies?
Advanced conductors have 2x higher amperage capacities and temperature limits than standard Aluminium Conductor Steel Reinforced (ACSR) used in AC transmission lines. This data-file screens Advanced conductors versus ACSR on dimensions such as tensile strength, performance and costs, and also screens leading companies.

Electric vehicle: battery life?
Electric vehicle battery life will realistically need to reach 1,500 cycles for the average passenger vehicle, 2,000-3,000 cycles after reflecting a margin of safety for real-world statistical distributions, and 3,000-6,000 cycles for higher-use commercial vehicles. This means lithium ion batteries may be harder to displace with novel chemistries?

Drone deployment: vertical take-off?
Drones cost just $1k-100k each. They may use 95-99% less energy than traditional vehicles. Their ascent is being helped by battery technology and AI. Hence this 14-page report reviews recent progress from 40 leading drone companies. What stood out most was a re-shaping of the defense industry, plus helpful deflation across power grids, renewables, agriculture,…

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…

Global trade: imports and exports, by product, by region?
Global trade is set to hit a new peak of $33trn in 2024 (30% of global GDP), of which 70-80% is for goods and 20-30% is for services. This data-file disaggregates global trade by product by region, across c20 categories of energy, materials and capital goods, which we follow in our research, and which are…

Jet fuel demand: by region and forecasts to 2050?
Jet fuel demand ran at 8Mbpd in 2019, the last year before COVID, and could rise to 18Mbpd by 2050, as global population rises 25%, jet fuel demand per capita doubles and fuel economy per aviation mile rises by 20%. This data file breaks down jet fuel demand by region, including our forecasts through 2050,…

Energy of rotation: angular momentum, inertia and flywheels?
This data-file calculates the energy stored in rotating masses. This includes 50Wh – 100 kWh flywheels. In power grids, the angular momentum of large rotating generators is known as ‘inertia’ and can run from 30kWh to 30MWH per turbine. Inertia has historically been a crucial part of stabilizing grids. Hence how do the physics work?…

Chlor-alkali process: the economics?
This data-file captures chlor-alkali process economics, to produce 80MTpa of chlorine and 90MTpa of caustic soda. Our base case requires $600 per ecu for a 10% IRR and a growth project costing $600/Tpa. Electricity is 45% of cash cost. CO2 intensity is 0.5 tons/ton. Interestingly, chlor-alkali plants can demand shift.

Pressure ratings: industrial and energy processes?
The purpose of this data-file is to chart the typical pressures of industrial processes and energy processes, as a useful reference. We are all used to 1 atmosphere of pressure, which is 1.0125 bar, 0.10125 MPa and 14.7 psi. But what pressures do industrial processes use?

Power cables: carrying capacity and loss rates?
This data-file calculates the power carrying capacity of power cables, plus the resistive losses of power cables. Both are modeled as a function of their voltage, current density, copper and/or aluminium content, resistance and connection type. Underlying data are drawn from data we have tabulated on over 100 conductors, their ratings and costs.
