What if producing green hydrogen didn’t require an electrolyser and the associated infrastructure?

In this episode of Exploring Clean Energy, host Andy Marsland is joined by Alana Barlow, CEO of Sparc Hydrogen, and Professor Greg Metha, Lead Researcher, to explore a different pathway for renewable hydrogen production: “photocatalysts” (PCs) and  “photoelectrochemicals” (PECs) for water splitting.

As the hydrogen sector works to overcome the cost and infrastructure challenges associated with conventional green hydrogen, Sparc Hydrogen is developing technology that uses sunlight to split water directly into hydrogen and oxygen.

Often described as “artificial photosynthesis”, the process has the potential to simplify hydrogen production by removing the need to first generate electricity and then feed that electricity into an electrolyser.

Alana and Greg take Andy inside the science, economics and commercialisation pathway behind the technology - from the challenge of electricity costs and the importance of solar-to-hydrogen efficiency, through to Sparc Hydrogen’s pilot plant in South Australia and its ambitions for commercial-scale deployment.

Meet the Guests

Alana Barlow - CEO, Sparc Hydrogen

Alana is CEO of Sparc Hydrogen, a production technology company developing low-cost photocatalytic water splitting technology.

Her career spans government, project development, asset management and commercial law, with the past six years focused on alternative energy including hydrogen and its derivatives, biogases and bio-liquids.

Previously working with Sumitomo Corporation across hydrogen, resources and energy, Alana led the final investment decision on the A$111 million Sumitomo Gladstone Green Hydrogen Project, developed in partnership with Rio Tinto.

Today, her focus is on enabling and emerging technologies capable of reducing the levelised cost of hydrogen and supporting the industry's next stage of development.

Professor Greg Metha - Lead Researcher, Sparc Hydrogen

Greg is a Professor of Chemistry and Co-Director of the Centre for Energy Technology at Adelaide University.

He established and convenes the international Hydrogen Production Technology (HyPT) series of forums and is involved in a range of international hydrogen research initiatives, including the NSF-CSIRO Global Center for Hydrogen Production, the IEA Hydrogen Technology Collaboration Programme and Mission Innovation's Sunlight-to-X Innovation Platform.

Greg heads the Metal Cluster Laboratory, where his research explores the physical and chemical properties of sub-nanometre metallic particles, novel catalysts and advanced photocatalytic reactors operating under concentrated solar radiation.

This research contributed to the establishment of Sparc Hydrogen, where Greg continues as Lead Researcher.

Key Takeaways

Green hydrogen's challenge isn't simply producing renewable electricity - it's accessing enough low-cost renewable electricity to make hydrogen economically viable at scale.

Photocatalytic water splitting offers a fundamentally different approach by using sunlight to produce hydrogen directly, potentially removing several pieces of electrical infrastructure required by conventional electrolysis.

For Sparc Hydrogen, solar-to-hydrogen efficiency is critical. Reaching and ultimately exceeding the key efficiency range could significantly change the economics of the technology.

But laboratory efficiency alone won't determine commercial success. Long-term durability, low-cost infrastructure, manufacturability and successful progression from pilot to commercial demonstration will all be important.

Perhaps most importantly, the episode highlights the continuing evolution of hydrogen technology. Electrolysis is not the only pathway being explored - and technologies emerging from research today could play a role in changing how renewable hydrogen is produced tomorrow.

Episode Overview

In this episode, Andy Marsland sits down with Neil McDonald, CEO of Gold Hydrogen, to unpack an exciting investment announcement and explore the future of natural hydrogen and helium in Australia. From historical discoveries that have led to cutting-edge drilling programs, this conversation dives deep into the potential of hydrogen as a clean, cost-effective energy source, and how helium (including the rare helium-3) could revolutionise industries from quantum computing to power generation and transportation.

Neil McDonald is co-founder and Managing Director of Gold Hydrogen, one of the first companies in the world to confirm that high natural hydrogen deposits exist underground. Gold Hydrogen is now leading the race to commercialise hydrogen, a near carbon-zero energy source which would impact worldwide zero emissions targets.

Gold Hydrogen is also progressing helium opportunities, as the hydrogen tests also produced strong helium showings, one of the first major finds in a non-petroleum area.

Neil has more than 20 years of extensive commercial experience in the energy and minerals sectors and has helped commercialise some of Australia’s largest exploration projects for private and public companies.

What You’ll Learn

• The origins of Gold Hydrogen and its pioneering work in natural hydrogen exploration
• Why South Australia’s geology is uniquely suited for hydrogen and helium extraction
• The significance of helium-3 and its astronomical value
• How natural hydrogen compares to green hydrogen in terms of cost, carbon footprint, and scalability
• Insights into Gold Hydrogen’s strategic partnerships with Toyota Motor Corporation, Mitsubishi Gas Chemical and ENEOS Xplora 
• The roadmap to commercial production and the role of infrastructure in scaling operations

Key Takeaways

• Natural hydrogen could be produced for under $1/kg, making it significantly cheaper than manmade alternatives
• Gold Hydrogen has confirmed helium purity levels of 36.9%, the highest ever reported globally
• Helium-3, valued at $15 million/kg, has been found in elevated levels in their wells
• The company’s exploration acreage spans 78,000+ square kilometres, with potentially enough hydrogen to power South Australia for 40+ years
