Sparc Technologies Shares Fall 8% on Cash Concerns Despite Green Hydrogen Progress – News and Statistics

Sep 29, 2026

Sparc Technologies saw its stock drop 8 percent to AUD 0.2300 on Thursday, according to Hydrogen Central, as traders weighed the company’s green hydrogen achievements against worries over its cash reserves and how quickly it can generate revenue.

The decline happened even though the company said its SHARP pilot plant in Adelaide had run continuously for six months and moved fully to automated reactor control. The system, which uses sunlight to split water directly, kept producing hydrogen amid extreme heat reaching 46 degrees Celsius, a test the joint venture with Fortescue regards as proof of the technology’s durability. Sparc is also advancing the process, with a prototype now being tested at the CSIRO Energy Centre in Newcastle.

Alongside hydrogen, the company is working on a second front in sodium-ion batteries, collaborating with a university to create anodes from organic waste as a sustainable substitute for conventional lithium components. Its graphene coatings division has already reached the commercial stage, with a partnership with industrial giant AkzoNobel delivering corrosion-resistant coatings to the Australian market. Initial customer programs for conductive coatings under the new SparcES product line are already in progress.

The market’s response, however, signals persistent anxiety about the company’s cash situation and the distance between technological potential and actual revenue. The stock has lost more than 16 percent in just the past week, reflecting investor concern about how fast the company can turn its research partnerships into reliable income. Sparc’s financial runway now depends on how quickly initial revenues arrive from its recent collaborations.

The AkzoNobel partnership is viewed as the most immediate near-term revenue source, with the specialty protective coatings being introduced in Australia. In addition, partner Petro Vietnam Paint intends to launch similar products in the coming months, creating another possible cash flow stream. How these coatings are received in both Vietnam and Australia will be crucial for the company’s liquidity.

Despite the recent decline, Sparc shares still show a gain of roughly 53 percent over the past twelve months. The next major catalyst will arrive in the second half of the year, when operational data from the Roseworthy hydrogen pilot plant is expected to offer a clearer view of whether the technology can produce hydrogen cost-effectively under real-world conditions. For now, the company’s task is to prove that its research breakthroughs can become sustainable earnings, a test that will decide whether the current sell-off is a buying opportunity or a warning sign.
