Hysata's efficiency bet pays off: first MW-scale electrolyser order lands 2026

Hysata makes capillary-fed alkaline electrolysers that split water into hydrogen at roughly 95% cell efficiency, aiming to make green hydrogen cheap enough for steel, chemicals and shipping to adopt.

That a ~95%-efficient capillary-fed cell, versus ~65% for rivals, would slash green hydrogen's biggest cost — electricity — and unlock first commercial orders.

US$111.3M Series B (May 2024), co-led by bp Ventures and Templewater; CEFC, POSCO Holdings, Shinhan Financial and TelstraSuper among participants.

Hysata was founded in the Illawarra region of New South Wales in 2021 and is led by CEO Paul Barrett. Its founding bet was that incremental improvements to conventional electrolysers would never make green hydrogen cheap enough for hard-to-abate industry: because electricity is the largest cost in hydrogen production, the company built its strategy around one lever — cell efficiency.

The capillary-fed alkaline cell feeds water to the electrode so hydrogen bubbles clear instantly, cutting electrical resistance; Hysata says the design runs at about 95% efficiency versus roughly 65% for incumbent stacks. In May 2024 it closed a US$111.3M Series B co-led by bp Ventures and Templewater to scale toward gigawatt manufacturing in Wollongong, with CEFC, POSCO, Shinhan Financial and TelstraSuper joining. A demonstration trial with ACWA in Saudi Arabia followed, and on 15 June 2026 Hysata announced its first binding megawatt-scale commercial order — an unnamed global heavy-industry leader in a hard-to-abate sector with secured hydrogen offtake — with delivery scheduled for the first half of 2027.

Still independent and scaling: Hysata says the order marks its transition from technology validation to commercial supply. It employs more than 120 people from more than 30 countries and is expanding partnerships across Asia-Pacific, North and South America, with growing interest in Europe and the Middle East. No exit has been announced.

Efficiency is the right lever: electricity is the largest cost in green hydrogen, so a cell at ~95% efficiency versus ~65% incumbents directly lowers the price customers pay.

The milestone is dated and hard: a binding megawatt-scale order signed 15 June 2026, with delivery in H1 2027, is concrete evidence the market will buy the technology.

Backing is institutional and global: bp Ventures, Templewater, CEFC, POSCO and TelstraSuper financed the US$111.3M Series B, de-risking a science bet.

The wedge is a physical redesign, not a cheaper copy: capillary-fed water supply and instant bubble removal cut resistance losses at the cell, so the product beats incumbents on performance.

Attack the physics, not the price list: the step-change that won Hysata its first order was removing the bubble-and-resistance losses rivals live with — not undercutting them on price.

As of July 2026 Hysata remains independent and scaling from Port Kembla. Its first megawatt-scale system is contracted for delivery in H1 2027 to an unnamed global heavy-industry customer with secured offtake, and it is running demonstration programs including a Saudi trial with ACWA. With 120+ staff, it reports expanding interest across Asia-Pacific, the Americas, Europe and the Middle East. The open question is whether efficiency leadership converts into multi-megawatt orders and gigawatt-scale manufacturing before hydrogen demand uncertainty cools the market.
