Industrial cooling: chillers and evaporators?
This data-file captures the costs of industrial cooling, especially liquid cooling using commercial HVAC equipment, across heat-exchangers, cooling tower evaporators and chillers. Our base case is that removing 100MW-th of heat has capex costs of $1,000/ton, equivalent to c$300/kW-th, expending 0.12 kWh-e of electricity per kWh-th, with a total cost of 7 c/ton-hour.

Solar insolation: by latitude, season, date, time and tilt?
Solar insolation varies from 600-2,500 kWh/m2/year at different locations on Earth, depending on their latitude, altitude, cloudiness, panel tilt and panel azimuth. This means the economics of solar can also vary by a factor of 4x. Seasonality is a key challenge at higher latitudes. Active strategies are emerging for orienting solar modules.

Pumped hydro: generation profile?
Pumped hydro facilities can provide long-duration storage, but the utilization rate is low, and thus the costs are high, according to today’s case study within the Snowy hydro complex in Australia. Tumut-3 can store energy for weeks-months, then generate 1.8 GW for 40+ hours, but it is only charging/dischaging at 12% of its nameplate capacity.

Electric vehicle cost breakdown by component?
This data-file disaggregates the $30k total cost of a typical new ICE and the c$45k total cost of a typical new EV, as a sum-of-the-parts, across 25 cost lines. Drivetrain costs are similar at $8-9k each. The key challenge for the EV is the battery. The electric vehicle cost breakdown shows promise for improving power…

Turbochargers: leading companies?
Six leading companies in turbochargers control two-thirds of the $15-20bn pa global turbochargers market. 55% of ICE vehicles now have turbochargers, which can improve fuel economy my as much as 10%, by enabling smaller and better utilized engines to achieve higher peak power ratings. What opportunities ahead, to adapt for vehicle electrification, or even if…

Companies mitigating radar interference of wind turbines?
Wind turbines create clutter and blind spots on radar systems, interfering with air traffic control, ocean monitoring and risks to national security and defence. These themes increasingly matter. Hence this data-file screens a dozen companies mitigating the radar interference of wind turbines, from large listed providers of next-gen radar systems, to start-ups developing nano-scale stealth…

Carbon markets: by category over time?
This data-file quantifies global carbon markets by category over time, including the EU ETS as an example of a compliance market, RECs, CCS and VERRA-certified “carbon credits”, across categories such as REDD, reforestation and other “carbon offsets”. We also draw analogies with charitable giving and forecast carbon markets out to 2050.

Helium production: the economics?
This economic model captures the production costs of helium, which is cryogenically extracted from low concentrations in natural gas. $200/mcf helium prices can support 10% IRRs on a resource with 2% helium content. $400-1,000/mcf spot prices can unlock 50-100% IRRs and trigger a capex boom. Economics can be stress-tested in this data-file.

Gas generation: what kind of bear is best?
This 20-page report compares combined cycle gas turbines (CCGTs), heavy-duty gas turbines, aeroderivative gas turbines, reciprocating engines and solid oxide fuel cells (SOFCs), on ten dimensions. No one gas generation technology is best. But modular solutions may increasingly rival CCGTs, especially for energizing AI data-centers?
