==> picture [10 x 12] intentionally omitted <==

Current Market: Hydrogen (H2) is a ~95Mtpa existing industry, primarily used in ammonia production for fertilisers, methanol for plastics and to remove sulfur from fuels.

Environmental Impact: Current hydrogen production generates over 1Gt of CO2 emissions annually, accounting for 2.5% of global emissions —equivalent to the entire aviation sector. There is an existing need to transition to green hydrogen to decarbonise the current hydrogen industry.

Huge Growth Potential: Green hydrogen is essential for decarbonising sectors like steelmaking, chemicals, cement, high-temperature heating, aviation, shipping, and heavy road transport, with demand projected to increase sixfold . by 2050[1]

Sparc Hydrogen is one of the only companies

combining concentrated solar with photocatalytic water splitting (PWS), advantages being:

• Reduced photocatalyst use.

• Modular and scalable mirror fields.

• Increased efficiencies and heat generation.

Sparc Hydrogen’s reactor is being designed to:

• Slot into an off-the-shelf linear Fresnel field.

• Utilise by-product heat for industry use or power generation.

Construction of a first-of-its-kind pilot plant utilizing Sparc Hydrogen’s concentrated solar based PWS system is underway.

The pilot plant will be located at the University of Adelaide’s Roseworthy Campus, ~50km north of Adelaide in South Australia.

The plant will utilize Sparc Hydrogen’s scalable reactor design and will represent a key milestone in derisking the technology. Construction commenced in March 2025 and plant is expected to be commissioned in mid-2025.

The Green Hydrogen Race Is On…

==> picture [9 x 11] intentionally omitted <==

==> picture [9 x 11] intentionally omitted <==

Conventional green hydrogen (electrolysis) projects will not reach industry and Government cost targets until well into the mid 2030s, at best.

As the costs and limitations of electrolysis projects have become clear, there is an increasing push towards developing new technologies which can unlock the substantial opportunity for green hydrogen to decarbonize existing hydrogen use cases and other hard to abate industries.

Sparc Hydrogen is in the right place at the right time with a substantial commercialisation

window providing an opportunity for a next generation low cost photocatalysis production technology.

Pathway To Market

Dual track approach to commercialising ecosparc[®] within the US$43 billion[1] global anti-corrosive coatings market:

1. Sparc is actively working with global coatings companies, regional coatings companies and additive suppliers on testing and trials.

2. Partnering with large asset owners to test eco on relevant steel infrastructure sparc[®]

under real-world conditions via field trials. Infrastructure owners being targeted include government, defence, mining, and oil and gas companies.

Anti-fouling Coatings

• Fouling is the result of accumulation of marine growth, resulting in reduced vessel speed, increased bunker consumption and high cleaning costs.

==> picture [9 x 10] intentionally omitted <==

Sparc is developing antifouling technology ( biosparc[TM] ) which substantially reduces fouling on marine vessels and for aquaculture.

==> picture [9 x 11] intentionally omitted <==

Sparc, together with Flinders University, was recently awarded a ~$350k grant from the Australian Government to further develop the technology.
