Reaching for the Stars with Paul Barrett, CEO of Hysata
Play • 52 min

Today Everything About Hydrogen had a chance to speak with Paul Barrett, the CEO of Hysata and dig into what makes this electrolysis company different.

About Paul Barrett:

With a PhD in Chemical Engineering from University College Dublin, many patents to his name, and decades of experience at the intersection of science, engineering and business, Paul has worked with everyone from early-stage tech start-ups to industry giants in water, materials & energy.  

As a former investment partner at IP Group Australia (LON: IPO), and close to a decade of electrolysis experience, Paul used his deep domain expertise to search the globe for game-changing approaches to hydrogen production. This led to the creation of Hysata, which closed its AUD$42.5M in Series A financing in mid-2022.

About Hysata:

Hysata is an Australian electrolyser manufacturing company developing a completely new type of electrolyser, featuring the world’s most efficient electrolysis cell coupled with a simplified balance of plant.

Hysata claims it’s electrolysers require only 41.5 kWh to produce 1 kg of hydrogen (vs. 50-55+ kWh/kg for the best commercial electrolysers). This ultra-high efficiency exceeds the efficiency target of the International Renewable Energy Agency (IRENA) for the year 2050. It also transforms green hydrogen production economics, to well under $2/kg.

Their patented technology was validated by Nature Communications in March 2022 and was in the top 1% of articles read across all journals tracked by Nature Communications in 2023. The stack performance has also been verified by a major EU electrochemical lab (publication pending).

The Hysata founding team comprises electrolyser industry veterans, with deep expertise in the design and scale-up of novel electrolysers. Building on that foundation they are growing a world-class engineering, manufacturing, and commercial team with a footprint in multiple continents. Backed by leading global investors, Hysata is moving rapidly towards manufacturing at the multi-gigawatt scale needed to address climate change.
