Highlights
Sparc Hydrogen attends World Hydrogen Summit 2026 in Rotterdam as part of the Australian trade delegation, engaging technology developers, industrial offtakers, and government representatives from 120 countries.
SHARP facility at Roseworthy marks six months of continuous operation, achieving fully autonomous control, sustained hydrogen production at maximum reactor design pressure, and performance through a 46°C South Australian summer.
European site visit advances integration work with concentrated solar partner in Valencia, Spain.
CEO Alana Barlow completes most extensive European business development trip to date across Spain, Germany, the United Kingdom, and the Netherlands.
I have just returned from eleven days across Spain, Germany, the United Kingdom, and the Netherlands — the most extensive European business development trip to date. The itinerary covered a working site visit with our concentrated solar partner, technology and industry meetings in Germany organised by Austrade, meetings with photocatalyst developers, and attendance at the World Hydrogen Summit in Rotterdam, where Sparc Hydrogen was represented as part of the Australian trade delegation.
The short version: Europe is moving with real momentum — in policy, in funding, and in project and technology development — and Sparc Hydrogen is well-positioned within it. The European Backdrop
The EU's commitment to green hydrogen has not wavered. What has changed since the early hype years is that frameworks are being implemented in reality — binding targets, regulatory infrastructure, dedicated funding instruments, and a growing pipeline of commercial projects that need new production technologies to work.
"In Europe, fossil fuels are unreliable." That observation would sound strange at home: but Europe has spent the past four years recalibrating its entire energy strategy around its energy vulnerability. Hydrogen is increasingly seen as a technology required for sovereignty, not just for the climate, and that changes the urgency of the conversations we are having.
State-level development banks are actively co-funding hydrogen projects. Industrial offtake demand is building across refining, aviation fuels, and hard-to-abate manufacturing. Thanks to strong policy, refineries are leading the way, with TotalEnergies executing a deal with RWE for 30,000 tonnes per annum of green hydrogen for the Leuna refinery in Germany in addition to another 45,000tpa of project development underway.
The funding environment for early-stage technology that can demonstrate a credible pathway to scale and low cost is genuinely open. This is a good time to be doing what we are doing.
World Hydrogen Summit 2026
The World Hydrogen Summit is the largest and most influential gathering in the global hydrogen industry, and the 2026 edition — held 19–21 May at Rotterdam Ahoy — was the biggest yet. Attendees from 120 countries, 500 exhibitors, and more than 300 speakers participated under the theme 'Climate, Energy and National Security: Unlocking Hydrogen Demand to Meet Global Priorities.'
A highlight was the opening day visit by His Majesty King Willem-Alexander of the Netherlands, who attended the ceremonial handover of the first section of the Gasunie hydrogen pipeline network — a tangible signal of how seriously the Netherlands is treating hydrogen infrastructure as a national strategic asset.
For Sparc Hydrogen, attending as part of the Australian trade delegation, gave us access to a remarkable concentration of counterparties: technology developers, catalyst suppliers, balance of plant specialists, industrial offtakers, state development banks, researchers, and government representatives, in a setting designed for exactly the kind of direct, substantive conversation that moves things forward. We also had the opportunity to meet with the Australian Ambassador to the Kingdom of the Netherlands, which opened some useful doors which will be pursued in future.
Working with our strategic suppliers
A core purpose of the trip was advancing our work with the strategic suppliers who form part of the Sparc Hydrogen system. In Valencia, Vinod and I spent time on-site with our concentrated solar partner: walking their operating facility, working through engineering questions around mirror systems, reactor mounting, and thermal management, and discussing how our respective technologies can continue to develop together unlocking mutual benefits.
Seeing a concentrated solar thermal system that has been running commercially for five years under a long-term energy supply agreement with a major international beverage company is a useful reminder of how far this technology has come and how well it integrates into industrial settings. It also generated some genuinely interesting thinking about what the next phase of our system integration could look like at industrial scale. Engaging the photocatalyst developer ecosystem
We also spent time meeting with photocatalyst developers, some established, some early-stage, all working on genuinely exciting science. The photocatalysis field is moving faster than most people outside it appreciate, and the quality of the researchers involved is high.
For Sparc Hydrogen, these conversations are strategic. We are actively engaging with high-potential partners in the photocatalyst space and assessing how Sparc's concentrated solar platform can bring their materials to commercial application and increase hydrogen yield at lower unit costs. Several of those conversations are progressing, and we expect to have more to say on this front in the coming weeks and months. Integrating the ecosystem
The thing that struck me most across this trip is how fragmented the direct solar-to-hydrogen / photocatalysis ecosystem still is. You have world-class photocatalyst researchers and developers on one side, and a growing demand for low-cost green hydrogen production systems on the other. It takes a skilled team to develop hydrogen production systems capable of scaling commercially, and the development of high efficiency photocatalysts will require reactor developers and system integrators like Sparc Hydrogen to bring their material to market. Given Sparc Hydrogen’s world class research team has years (in some case decades!) of experience in testing and optimising photocatalysis operating systems, particularly under concentrated sunlight, we are strategically positioned to facilitate this transition to commercialisation.
From photocatalyst development through to reactor design, system integration, and hydrogen production at scale, building that end-to-end pathway is the work. The conversations we had in Europe confirmed that the demand for it is real, the partners and funding is there, and the timing is right. SHARP Milestone
Our immediate priority on return to home base is unchanged: stress-testing the performance of our SHARP facility at Roseworthy, continuing to procure and validate world leading photocatalysts and building the end-to-end system integration which will see this exciting technology transition into commercial reality.
This week, SHARP will celebrate 6 months of continued operation, which has built on years of laboratory and prototype testing. Over this period, the plant has achieved fully autonomous operations including safe remote start-up and shut-down; sustained hydrogen production at maximum reactor design pressure and elevated temperatures; and maintenance of set-point temperature under naturally variable solar conditions, including through a harsh South Australian summer with ambient temperatures reaching 46°C.
Photocatalyst material performance and durability have been maintained for six months of continuous testing, and solar-to-hydrogen efficiency measurements are being recorded and benchmarked against laboratory results. .
Only through this work can we validate the performance of photocatalytic water splitting in the real-world and make electricity-free green hydrogen production a reality.
