About Harnyss

The Harnyss Oasis platform provides electrostatic, non-lithium energy storage, scalable from 100 kWh to over 100 MWh. With nanosecond response times and zero degradation, Oasis ensures stable power delivery while significantly reducing operational costs compared to lithium-based systems. Onboard hydrogen backup replenishes stored power and enables true black start functionality, ensuring uninterrupted energy supply in mission-critical environments.

The Oasis H2 is a modular hydrogen energy system integrated into TRICON (Triple Container) military-grade modules. It enables onsite hydrogen production using atmospheric water capture, electrolyzers, and low-pressure solid-state hydrogen storage. Energy conversion is provided by fuel cells or internal combustion engines (ICE). Oasis H2 can also be configured as standalone hydrogen storage units if needed.

The Oasis platform is a microgrid-in-a-box, delivering a self-contained, modular, and scalable energy solution for diverse applications:

• Microgrids – Oasis modular microgrid solutions range from 100 kWh to 100+ MWh, providing stable, cost-efficient energy for remote sites, industrial facilities, and critical infrastructure.
• EV Charging – Electrostatic energy storage enables Level 3 and DC-coupled fast charging for grid-tied and solar-powered stations, eliminating the need for transformers. With solar, there’s no interconnection delay or added expense.
• Power Purchase Agreements (PPAs) for Islands, Tribal Nations, and Communities – Oasis enables cost-competitive renewable microgrids under long-term PPAs, delivering significantly lower energy costs than diesel-based grid power. Our 20-30 year agreements reduce CAPEX and OPEX, ensuring stable, predictable electricity pricing while improving energy resilience.

Modern data centers require precise power conditioning to ensure stable operation and protect sensitive computing loads. Harnyss electrostatic energy storage stabilizes voltage and frequency from both grid power and on-site generation, eliminating fluctuations that can impact performance.

With nanosecond-level response times, the Oasis platform serves as a buffer between incoming power sources and AI-driven workloads, absorbing transient spikes and delivering consistent, high-quality power. Unlike lithium-based systems, Oasis handles high-frequency load variations without degradation, ensuring uninterrupted power delivery for high-performance computing, GPU clusters, and critical infrastructure.

In addition to grid stabilization, the system provides UPS functionality, peak shaving, and black start capability, offering a scalable backup storage solution from 1 MWh to 100+ MWh with no thermal runaway risks or capacity fade over its 20-30 year lifespan.

Harnyss Oasis and Oasis H2 platforms deliver mission-ready energy storage for forward operating bases (FOBs), military bases, shore power, communications infrastructure, and shipboard applications. Our non-lithium electrostatic storage provides long-duration, high-efficiency power with nanosecond response times, ensuring stable energy for radar, command centers, and critical systems. Integrated low-pressure hydrogen storage enables on-site fuel production, powering fuel cells or internal combustion engines (ICEs) for backup power and black start capability—eliminating reliance on diesel supply chains. Designed for extreme environments (-40°F to 150°F), rapid deployment, and scalable from 10 kWh to 100+ MWh, Oasis enhances energy security, operational efficiency, and logistics resilience for modern military operations.
