Carbon280, the Perth-based materials-engineering company developing next-generation hydrogen separation, storage and transport solutions, has signed a Memorandum of Understanding (MoU) with natural hydrogen explorer H2EX.
The agreement follows Carbon280’s successful presentation of its Hydrilyte technology at the Australian Natural Hydrogen Conference, where the company showcased results from mixed-gas testing, using a blend representative of natural hydrogen.
The tests confirmed Hydrilyte’s ability to separate hydrogen from helium and other gases, while safely storing the hydrogen ready for transport, all in a single, integrated step.

Carbon280 has now completed and commissioned its pilot plant, alongside its dedicated Kwinana laboratory where helium–hydrogen separation has been successfully demonstrated. Together, these facilities mark a major de-risking milestone and confirm the readiness of Hydrilyte for scale-up.
The company is now moving into its next phase, and is converting the pilot system to continuous operation, a critical step toward commercial deployment and large-scale natural hydrogen processing.
To accelerate this progression, Carbon280 has launched a seed funding round, targeted to close in February 2026. The investment will support optimisation of the continuous-flow process, expanded mixed-gas separation tests, and preparation for early pre-commercial field trials.
Carbon280 is building a low-carbon, safe and economically compelling pathway to natural hydrogen, unlocking its potential as a globally competitive energy and industrial feedstock.
“One of the biggest bottlenecks for natural hydrogen is how to separate, transport and store it safely,” H2EX founder and CEO Mark Hanna said.

“As H2EX progresses from exploration to production, we need a solution that can efficiently separate hydrogen from other gases and deliver it to customers. That’s why Hydrilyte is so important. It brings separation and logistics together in a single, elegant step.”
“Natural hydrogen developers are targeting production costs of US$1–2/kg,” Carbon280 founder and CEO Mark Rheinlander said.
“Our goal is to keep separation, storage and release under US$1/kg at scale. When you combine natural hydrogen’s cost advantage with Hydrilyte’s simplicity and safety, you have a pathway to hydrogen that is globally competitive, low-carbon and ready for real-world industrial use.”
