EV fast charging: opening the electric floodgates?
This 14-page note explains the crucial power-electronics in an electric vehicle fast-charging station, running at 150-350kW. Most important are power-MOSFETs, comprising c5-10% of charger costs. The market trebles by the late 2020s.

HVDC transmission: leading companies?
The global HVDC market is $10bn pa, and it might typically cost c€100-600 M to connect a large and remote renewables project to the grid or run a small HVDC inter-connector. This data-file reviews the market leaders in HVDC, based on 5,500 patents. A dozen companies stand out, with c$40bn of combined revenues from power…

FACTS: costs of STATCOMs and SVCs?
Flexible Alternating Current Transmission System components (FACTS) include Static Synchronous Compensators (STATCOMs) and Static VAR Compensators (SVCs). A typical wind project has 0.5 – 1.0 kVAR of FACTS per 1.0 kW of real power capacity. Each kVAR of SVCs and STATCOMs costs $100/kVAR and $150/kVAR respectively.

Hillcrest: ZVS inverter breakthrough?
Hillcrest Energy Technologies is developing an ultra-efficient SiC inverter, which has 30-70% lower switching losses, up to 15% lower system cost, weight, size, and thus interesting applications in electric vehicles. How does it work and can we de-risk the technology?

Silver demand: upside and substitution?
This data-file is a simple demand outlook for silver in the energy transition. Demand could rise 2.5x from 30kTpa to 85kTpa in 2050, driven by solar and electrification. Although in practice, we think a price spike will displace silver with copper.

Power grids: global investment?
Global investment into power networks averaged $280bn per annum in 2015-20, of which two-thirds was for distribution and one-third was for transmission. Amazingly, these numbers step up to $600bn in 2030, >$1trn in the 2040s and can be as large as all primary energy investment.

Solar volatility: tell me lies, tell me sweet little lies?
This 20-page note quantifies the statistical distribution of short-term volatility at solar power plants. Solar output typically flickers downwards by over 10%, around 100 times per day. Can industrial processes truly be ‘powered by solar’? What opportunities will arise to buffer the volatility?

Green hydrogen: can electrolysers run off renewables?
What degradation rate is expected for a green hydrogen electrolyser, if it is powered by volatile wind and solar inputs? This 15-page note reviews past projects and technical papers. 5-10% pa degradation rates would raise green hydrogen costs by $1/kg. Avoiding degradation justifies higher capex, especially on power-electronics and even batteries?
-
Battery degradation: causes, effects & implications?
This 14-page note offers five rules of thumb to maximize the longevity of lithium-ion batteries, in grid-scale storage and electric vehicles. The data suggest hidden upside in the demand for batteries, for lithium and high-quality power electronics, especially if batteries are to backstop renewables.

Solar: energy payback and embedded energy?
What is the energy payback and embedded energy of solar? We have aggregated the consumption of 10 different materials (in kg/kW) and around 10 other energy-consuming line-items (in kWh/kW). Our base case estimate is 2.5 MWH/kWe of solar and an energy payback of 1.5-years. Numbers and sensitivities can be stress-tested in the data-file.
