Quokka™ Hybrid Electric‑Hydrogen Energy Storage System by H2Gremm is an innovative solution that integrates solar generation, lithium-ion battery storage, and hydrogen production/storage modules to address the growing demand for efficient energy storage and utilization in residential, municipal, and commercial settings. The system is designed to optimize energy flow, provide seasonal storage, and support building heating and light mobility through hydrogen refueling.

The core concept of Quokka™ revolves around utilizing surplus solar energy during the day to charge batteries for immediate use, with excess energy being electro‑chemically converted into hydrogen and stored in modular tanks. This stored hydrogen can then be used to power fuel cells when needed, such as at night or in winter, offering a reliable source of electricity and enabling load shifting.

Each Quokka™ unit is compact and plug-and-play, making installation and maintenance easy. The system also includes onboard energy management software that ensures optimal energy utilization, smoothing peaks and enhancing flexibility. With capacities ranging from 5 to 100 kWh of batteries and 1 to 10 kg/day of hydrogen, Quokka™ is a versatile solution that caters to a wide range of energy storage needs.
