Hello Hydrogen.
Welcome to Work.

LAVO puts hydrogen to work as long-duration energy storage for critical infrastructure. A lithium-ion buffer responds instantly to changing loads, while solid-state hydrogen storage provides the energy reserve for extended operation.

Immediate response. Extended runtime. Built for continuity.

Commercial system

Hydrogen energy storage system built to scale

C&I HESS is LAVO’s commercial hydrogen energy storage system for businesses, infrastructure and utility-scale installations.

The integrated system brings together an electrolyser, water purifier, metal hydride storage vessels, fuel cell, hybrid inverter and a small lithium-ion buffer.

Lithium provides fast, short-duration response while hydrogen extends storage across days and weeks. The technologies are complementary parts of the same system.

For long-cycle resilience, HESS is designed as a safer, cleaner and more economical alternative to diesel generation at comparable system efficiency.

Integrated architecture

One system, working across time

HESS coordinates generation, immediate use, storage and power delivery inside one integrated architecture.

  1. Generate

    Make hydrogen

    Surplus renewable electricity is used to prepare water and produce hydrogen.

    • Water purifier
    • Electrolyser

  2. Use

    Respond immediately

    A lithium-ion buffer supports fast, short-duration demand, while LAVO HESS can also integrate with existing battery storage where suitable — adding long-duration hydrogen storage to your current energy infrastructure.

    • Lithium-ion buffer

  3. Store

    Hold energy longer

    Hydrogen is retained in metal hydride vessels for energy resilience measured in days and weeks.

    • Metal hydride hydrogen storage vessels

  4. Power

    Return useful power

    Stored hydrogen is converted back to electricity and conditioned for the connected load.

    • Fuel cell
    • Hybrid inverter

Lithium and hydrogen are complementary: lithium handles rapid response, while hydrogen carries energy across longer periods.

Designed for resilience

A cleaner path beyond diesel

HESS is intended for sites that need dependable energy beyond short battery-duration windows, including businesses, infrastructure and utility-scale installations.

At comparable system efficiency, the system is designed to provide a safer, cleaner and more economical long-cycle alternative to diesel generation.

Residential origins

Where the LAVO story began

The residential LAVO System remains part of LAVO’s story and a future energy-storage scenario for homes.

LAVO Ecosystem

Where else the hydrogen could go

Alongside the energy systems, LAVO has explored what solid-state hydrogen might power once it is safe to hold and simple to carry. These are design concepts. Neither is manufactured, and neither is for sale.
