This 14-page note explains the crucial power-electronics in an electric vehicle fast-charging station, running at 150-350kW, to charge up an entire EV in 10-30 minutes. Most important are power-MOSFETs, comprising…
…US electric utilities include rising capex, especially for renewables, the phase out of coal, building out electric vehicle infrastructure and a target of reaching net zero by 2050 or before….
This data-file compares diesel trains, electric trains and hydrogen trains, according to their energy consumption, carbon emissions and fuel costs. The data are presented apples-to-apples, per passenger mile, based on…
This data-file tabulates the greatest challenges for lithium ion batteries in electric vehicles, which have been cited in 2020’s patent literature. Specifically, the work contains a sample of 100 patents…
Variable frequency drives precisely control motors. Amazingly they could reduce global electricity demand by c10%. We expect a sharp acceleration due to sustained energy shortages, increasingly renewable-heavy grids and excellent…
…electric vehicles are needed in the energy transition. Our estimates of volumes, oil market implications, and CO2 credentials are refreshed on page 5. So how do the economics compare for…
When electric vehicles are widespread, how will we fuel them? Our model shows the economics can be compelling for powering fast-chargers using gas turbines. $289.00 – Purchase Checkout Added to cart The…
In 2019, the virtues of switching diesel-powered frac fleets to gas-powered electric have been extolled by companies such as EOG, Shell, Baker Hughes, Halliburton, Evolution and US Well Services. The…
It is widely believed that electric vehicles will destroy fossil fuel demand. We find they will increase it by 0.7Mboed from 2020-35. EVs only start lowering net fossil fuel demand…
This data-file tabulates the greatest challenges for charging electric vehicles, based on the recent patent literature, looking across fifty patents filed by leading companies. Our top three conclusions are that…
