Can Supercapacitors Smooth AI's Power Swings?
AI workloads can create load swings far sharper than steady-state compute, producing hard power spikes that conventional architectures struggle to absorb. Supercapacitors, also called ultracapacitors, sit between conventional capacitors and batteries. They store energy as a surface charge rather than through a battery’s chemical reaction, which gives them higher power density than batteries but lower energy density. That trade-off suits short, frequent bursts rather than sustained runtime. Operators are testing supercapacitors alongside batteries and uninterruptible power supply (UPS) systems rather than replacing them. Batteries and UPS systems still support the sustained load and provide a longer backup window. A September 2026 report from IDTechEx identifies three roles for supercapacitors in data centers: voltage stabilization, peak shaving, and short-term backup power. Supercapacitors charge and discharge in milliseconds to seconds – fast enough to track AI training cycles and recharge before the next spike. Market Outlook: Small Today, Growing Fast IDTechEx projects the data center supercapacitor market will reach $950 million by 2037, a 40.9% compound annual growth rate from 2026. That growth rate stands out against the wider category. A separate IDTechEx report from August 2025 puts total global supercapacitor revenue across automotive, grid, and industrial uses at $4.86 billion by...

Straubel was working on a "Long Range EV" project at Stanford, built around ACP tech, which was a prototype for what would ultimately become the Roadster.Straubel was later invited to a lunch with Musk by a former VP of Compaq (which bought Zip2), hearing of Musk's college work on EV ultracapacitors

I have wondered why EVs cannot be equipped with ultracapacitors to store top-up charges that can be then passed to the primary batteries over the next half hour after cable disconnect. Yes, price, but luxury marques would not care.

Ultracapacitors are pretty nifty on their own, but probably not as much as even regular raptors.

It was kind of a badass MacGyver kind of car! We converted a golf cart motor into a generator and ran it at constant peak efficiency to keep a bank of ultracapacitors charged, and I'm kind of amazed nobody got hurt honestly. (Another car did have one explode, but the whole thing was in a plexy box)

7. Ultracapacitors . I can't find it but 10-15 years ago some guy got investment money from GM for a capacitor that could store so much charge you could drive hundreds of miles on it. I would bet a car that it was a scam from day zero, but I have no proof.
