Oil: what happens when you defer or curtail production?
The aim of this data-file is to tabulate technical papers into production deferrals at oil and gas fields. The impact depends on the reservoir type, but generally we expect shut-ins during the 2020 COVID crisis will lower effective production capacity. Shale and Middle East producers could be relatively better placed.

Organic Rankine Cycles: the energy economics?
This data-file captures the energy economics of an Organic Rankine Cycle to recover low-grade waste heat (at 70-200C) from an industrial facility, or in the geothermal industry. A CO2 price of $50-75/ton could greatly accelerate adoption and improve the efficiency of industrial facilities.

Electric trucks: what battery sizes?
An electric truck would need a 15 ton battery to match the c2,500-mile range of a diesel truck. However, larger batteries above c8-tons detract 10% from fuel economy and may cause trucks to exceed regulatory weight limits, lowering their payload capacities. 4-6 ton batteries with 700-1,000km ranges are optimal.

Cryogenic air separation: costs and energy economics?
This data-file calculates the costs of cryogenic air separation units, which are important in the production of industrial gases, ammonia, metals, materials, medical applications and new energy technologies such as blue hydrogen. Good base cases are $100/ton oxygen, $20/ton nitrogen, $200/Tpa capex and 60kWh/ton of electricity (on an input air basis).

Green hydrogen electrolysers in Europe: a database?
This data-file derives conclusions into green hydrogen electrolysers in Europe, based on c240 distinct projects. The market is shifting away from smaller alkaline electrolyers to super-giant PEMs and SOECs. Key controversies are visibly emerging around power sources and hydrogen uses.

Electrical conductivity: energy transition materials?
Electrical conductivity of energy transition materials is tabulated in this data-file. ‘The action’ takes place in the range of 10^-8 to 10^-3 Ohm-meters, including silver in solar cells, copper in renewables and EVs, aluminium transmission lines, batteries, and solar semiconductors.

Vehicles: energy transition conclusions?
Vehicles transport people and freight around the world, explaining 70% of global oil demand, 30% of global energy use, 20% of global CO2e emissions. This overview summarizes all of our research into vehicles, and key conclusions for the energy transition.

Eaton: breakdown of revenues by product category?
Eaton is a power-electronics super-giant, listed in the US, employing 86,000 people, generating $20bn per year of revenues. We have aimed to guess how $20bn pa of net sales is distributed across 200 different product categories. 75% is exposed to power-electronics, with tailwinds in the energy transition.

CH4 context: the largest methane leaks of all time?
Global methane emissions run to 360MTpa. 40% is agriculture, 40% is the energy industry and 20% is landfills. Within energy, over 30% of the leaks are from coal, 30% are from oil, 27% are from gas. This short note quantifies some of the largest methane leaks of all time, and provides context for the recent…

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?…
