Megawatts in milliseconds

Flywheel energy storage that delivers 1 megawatt in under 10 milliseconds, sustained for tens of minutes. Kinetic power with no chemistry, no degradation, no replacement cycle. Built for grid and micro-grid, industrial peak loads, marine, and oil and gas.

FLYWHEEL ENERGY STORAGE

Power that doesn't wait. Storage that doesn't wear out.

Batteries store energy. Supercapacitors deliver fast bursts. Diesel generators run for hours, but they take seconds to start. Teraloop technology is a new generation flywheel that delivers megawatts of real power in milliseconds, holds it for full minutes, and does it again and again without wearing out.

A mass spinning in a vacuum. No chemistry to degrade, no fuel to burn, no fire to suppress, no replacement cycle to plan around. Safe by design, maintenance-free. Discharge it 200 times a day for 25 years and it doesn't care.

WHY A FLYWHEEL ENERGY STORAGE

Four advantages no other technology delivers

01 · Instant response

10 ms to full power

100% nominal power in under 10 milliseconds. Faster than chemistry, before a diesel generator even knows you need it.

< 10 ms · 1 MW

02 · Infinite durability

No cycle limit

A mass spinning in a vacuum. Nothing inside the housing degrades. Cycle it infinite times per day for 25 years.

∞ cycles · 25 yrs

03 · Inherent safety

No fire risk

No suppression system, no climate-controlled room, no permits where chemistry isn't allowed. EX-zone qualified.

EX zone · marine ready

04 · Ships in a container

Plug and play

Commission in days, not weeks. Maintenance is near-zero. If a module ever fails, swap it — no on-site repair.

Container-ready

WHERE TERALOOP WINS TODAY

Where flywheels fit best

 
Voltage drop on an oil and gas drilling site, caught by a flywheel in under 10 milliseconds

Oil & gas onshore drilling

A voltage drop stops a pump. A membrane sticks. The damage is immediate and physical. Batteries and super-capacitors aren't allowed near a drilling field. Fire brigades won't permit chemistry in an EX zone. Diesel generators can't react fast enough to catch the drop.

A flywheel sits in line and supports the voltage in under 10 milliseconds. Its footprint is small enough to drop onto a platform deck or into a remote container, indoor or outdoor, in dust or in heat. No chemistry. No fire risk. No replacement cycle.

 
Grid frequency dip and recovery, with a flywheel injecting power to hold 50 Hz

Grid, micro-grid and island frequency stabilization

Power grids in Europe are designed to operate at constant frequency of 50Hz (±0,2Hz). When supply and demand fall out of balance, the frequency dips or spikes, and the grid has seconds to correct it before things start tripping offline. Renewables make this harder: solar and wind drive sharper, faster swings than the grid was built for.

A flywheel sits on the grid spinning. Within 10 milliseconds of a dip or spike, it pushes power in or pulls it out — without the cycle damage a battery would take from doing this thousands of times a day.

Industrial load profile with peak shaving by a Teraloop flywheel inline between grid and machinery

Industrial voltage drop and peak shaving

Industrial sites with large motors, pumps, presses, and compressors need voltage support or brief moments of very high power. Those peaks set the demand charge the site pays every month and accelerate wear on every machine they spike through.

A flywheel sits between the grid and the load, protecting equipment and saving on maintenance, materials, and downtime. It also smooths the peaks when they come. The grid sees a flatter load profile, the monthly demand charge drops, and the equipment lives longer.

 
Teraloop flywheel on a marine deck, delivering power quality without flammable chemistry

Marine applications

Marine sites, whether an offshore platform or a vessel, have to deliver power quality in an environment where chemistry is not an option. A Teraloop flywheel sits inline, catches voltage drops in milliseconds, and runs on the same deck as the equipment it protects without flammable electrolyte or a replacement cycle inside a 25-year life. No fire brigade is coming at sea, and our flywheel does not need one.

Where else flywheel storage works

TECHNOLOGY

Our flywheel energy storage system

A Teraloop flywheel stores energy as motion: a hubless rotor spinning in a vacuum, with no chemistry inside, no friction, no contact wear. It delivers 100% of its rated power in less than 10 milliseconds and sustains that output for tens of minutes.

That covers the response window most grid and industrial events actually fall into: the milliseconds where chemistry cannot react, and the minutes where supercapacitors run out. Nothing inside the housing degrades with use, so the machine that ships this year performs at full spec 25 years from now.

What is a Teraloop flywheel

A Teraloop flywheel is a kinetic energy storage system. It stores electricity as the rotation of a hubless mass spinning in a vacuum, then converts that motion back to electrical power on demand. It delivers a megawatt in under 10 milliseconds and sustains output for up to 15 minutes, with no chemistry to degrade and no fire risk.

Flywheel installed inline at a dairy factory on Terceira island, Azores, catching voltage dips on a weak island grid

CASE STUDY

A factory eliminated production interruptions caused by voltage drops.

A main dairy producer on Terceira, an island in the Portuguese Azores. The island grid runs on limited inertia, and production line was paying for it: dozens of short voltage dips a year, each one stopping critical equipment and ruining batches. Delays, extra labour, and rejected product added up to roughly €100,000 in annual losses.

Teraloop installed a 100 kW flywheel inline at the factory in April 2024. It runs 24/7, catching sub-200 millisecond voltage dips before production stops and injecting fast frequency reserve when the island's grid drifts off 50 Hz. Verified response at the connection point: 15 milliseconds.
