MacroCaps Megawatt-Scale Power in Milliseconds
Supercapacitor technology where power, stability, efficiency, and sustainability come together to create a greener, more resilient world.
Unique Applications
Each MacroCap unit delivers 2.7V and 25,000F, and our patented electrode architecture lets units be stacked in series or parallel — cable-free — inside custom rack and cabinet systems. The result: a supercapacitor platform that scales from a single cabinet to containerized megawatt installations without redesigning the system architecture.
For technical teams, that means fewer connection points, lower failure risk, and simpler maintenance. For the business, it means faster deployment, lower total cost of ownership, and a storage technology that qualifies for grid-stabilization and green-energy integration projects today — not five years out.
This positions us as a leading professional participant not only in the supercapacitor market but also significantly contributes to shaping a sustainable and efficient future for integrating green energy sources into the power grid.
Our unique MacroCaps units can be serialized and/or connected in parallel within our self-developed custom-made rack systems and assembled into modular cabinet solutions. These solutions are not only innovative but also environmentally friendly. At MacroCaps, we focus on several areas, including:
Grid & Frequency Regulation
Absorbs and releases energy in milliseconds to hold grid frequency near 50Hz — reducing curtailment costs and deferring infrastructure upgrades.
Defense & Military
Delivers instant high-power discharge for pulsed-load systems, built to MIL-adjacent ruggedization standards for mission-critical uptime.
Kinetic Energy in Cranes & Lifts
Captures regenerative braking energy for reuse, cutting grid draw and extending component life — lowering both energy bills and maintenance spend.
Hybrid Systems
Pairs with batteries for fast charge/discharge cycling, extending battery lifespan and reducing replacement capex.
Charging Infrastructure & Automotive
Enables high-rate charging without oversizing grid connections, supporting faster EV rollout at lower infrastructure cost.
Stability for Hydrogen Production
Smooths power delivery to electrolyzers across load ranges, improving yield consistency and equipment longevity.
Environmental Sustainability
Committed to sustainability, we help reduce carbon emissions by enabling more efficient power management.
Based on our patented architecture, MacroCaps energy storage technologies unlock entirely new possibilities for high-power electrification
MacroCaps is working towards a greener future
MacroCaps is working towards a greener future. We prioritize supporting renewable and sustainable energy sources as a cornerstone of our mission. Our supercapacitors not only reduce energy losses and enhance system efficiency but also facilitate businesses in integrating and stabilizing green energy sources in their production processes.
We are dedicated to minimizing our environmental impact and supporting global green initiatives. Regardless of the application, our supercapacitors contribute to more efficient energy utilization and storage.
About MacroCaps
Founded in 2016, MacroCaps engineers supercapacitor systems on a patented, cable-free architecture. We work with grid operators, OEMs, and industrial partners to replace costly over-engineering — oversized batteries, redundant grid capacity — with right-sized, high-power storage that pays back in reliability and lower lifecycle cost.
Our modular and cable-free systems allow for fully customized solutions, ranging from grid stability to green energy systems. At MacroCaps, we operate not just with the vision of technological advancement but also with the mission of shaping a cleaner and brighter future.
