Can solar reach 45% of a power grid?

…May, at +/- 15%. And highest at midday in May, when 34MW of excess demand must be absorbed, in our 100MW grid. https://thundersaidenergy.com/2023/07/20/smooth-operators-who-benefits-from-volatile-power-grids EV charging helps to contextualize our demand-shifting…

Battery degradation: what causes capacity fade?

Battery degradation rates

…battery degradation is minimized by limited cycling, slower charging-discharging, stable temperatures and LFP chemistries. $449.00 – Purchase Checkout Added to cart In the underlying laboratory studies that we have assessed, researchers have…

Electric vehicles: chargers of the light brigade?

economics of EV charging stations

This 14-page note compares the economics of EV charging stations with conventional fuel retail stations. They are fundamentally different. Our main question is whether EV chargers will ultimately get over-built,…

Form Energy: long-duration battery breakthrough?

Form Energy battery challenges

…fuel anode, which metallizes during charging (gain of electrons) and which oxidizes during discharging (loss of electrons). At the air-breathing cathode O2 gas ionizes into the solution during discharging (gain…

MOSFETs: energy use and power loss calculator?

…or layers of MOSFETs and IGBTs (example below). Roughly, flowing power through 6 MOSFETs, each at c2% losses, explains why the EV fast-charging topology depicted below might have losses in…

Energy storage: top conclusions into batteries?

Conclusions into batteries

…for daily charging-discharging (model here). Conversely, there are many loads in the power grid that can shift their demand (e.g., to the times when grids are over-saturated with renewables). This…
