# Hysata

> Hysata is an Australian clean-energy manufacturer commercialising a capillary-fed electrolyser that splits water into hydrogen at around 95% system efficiency, well above conventional electrolysers. Spun out of the University of Wollongong, the company aims to produce green hydrogen at the lowest cost to help decarbonise hard-to-abate sectors such as steel, chemicals and heavy transport, and is scaling toward gigawatt-scale manufacturing at Port Kembla, New South Wales.

- **Founded:** 2021
- **Headquarters:** Wollongong / Port Kembla, New South Wales, Australia
- **Founders:** Paul Barrett (Co-Founder & CEO), Gerry Swiegers (Co-Founder & Chief Technology Officer (inventor of the capillary-fed cell)), Tom Campey (Co-Founder)
- **Team size:** ~120 employees
- **Products:** Capillary-fed electrolyser, 5 MW electrolyser system
- **Notable:** Demonstrated a capillary-fed electrolysis cell at 98% cell energy efficiency (~95% system efficiency, 41.5 kWh/kg), published in Nature Communications., Exceeded IRENA's 2050 electrolyser efficiency targets years ahead of schedule., Closed US$111M Series B (2024) - reported as the largest Series B in Australian clean-tech history.

## Products & services

- **Capillary-fed electrolyser** — A modular alkaline electrolyser using capillary action to feed water to the electrodes, eliminating gas bubbles that add electrical resistance. Demonstrated ~95% system efficiency (41.5 kWh/kg), with a simplified balance of plant designed for mass manufacturing.
- **5 MW electrolyser system** — Next-generation megawatt-scale system being built and tested at Hysata's Port Kembla manufacturing facility, with field pilots planned ahead of commercial gigawatt-scale rollout.

## Achievements

- Demonstrated a capillary-fed electrolysis cell at 98% cell energy efficiency (~95% system efficiency, 41.5 kWh/kg), published in Nature Communications.
- Exceeded IRENA's 2050 electrolyser efficiency targets years ahead of schedule.
- Closed US$111M Series B (2024) - reported as the largest Series B in Australian clean-tech history.
- Named Startup of the Year at the 2023 Startup Daily Best in Tech Awards.
- Attracted strategic investment from bp, POSCO, BlueScope, Vestas and sovereign wealth (Oman Investment Authority).
- Reported ~9.4 GW of conditional orders / letters of intent and a first binding megawatt-scale order.

## Latest updates

- **2024-05** — Closed US$111M Series B co-led by bp Ventures and Templewater, the largest clean-tech Series B in Australian history.
- **2024-12** — Signed Joint Development Agreements with POSCO Holdings and POSCO E&C to co-develop high-efficiency electrolyser technology.
- **2025** — Building and testing a 5 MW next-generation system at its Port Kembla facility, with a field pilot at Stanwell planned.
