 both nanoparticle-based and thin-film modules. This design enables
the production and separate collection of hydrogen (H₂) and oxygen (O₂) gases without the need for expensive ion-exchange
membranes, thereby reducing system cost and complexity. This membrane-free approach was recently validated as a first-of-its-kind method,
confirming effective hydrogen/oxygen separation in a working system without using a membrane.

●Joint Validation and Testing: We engaged in extensive third-party evaluation of both technology pathways. At Honda R&D’s
facilities in Tochigi, Japan, our integrated hydrogen modules (including 100 cm² and 1,200 cm² units) were tested under real-world
on-sun conditions, providing critical validation of their performance. We also validated our 1200 cm2 units in simulated sunlight
for various operating temperatures and electrolyte conditions at the University of Tokyo labs using their state-of-the-art solar simulator
system. In parallel, through the EU-sponsored NanoPEC project led by Fraunhofer CSP, our partners are conducting long-term stability testing
of the nanoparticle-based semiconductor units – including the development of specialized LED solar simulator stands and outdoor
test benches – to ensure these reactors maintain performance over extended operation under use conditions. These rigorous evaluations
are essential to verify performance, durability, and scalability, ensuring our technologies meet the highest standards prior to commercialization.

●Pilot Plant Engineering and Scale-Up: Contracted The Process Group (TPG Engineers) to carry out the front-end engineering design
for a pilot-scale renewable hydrogen production plant exceeding 25 m² of active area. Building on our successful 1 m² multi-module
demonstration, this pilot design calls for approximately fifteen interconnected PEC panels (each ~1.92 m²) integrated with full balance-of-system
infrastructure. TPG’s engineering scope includes the integration of our PEC modules with fluid circulation systems, mechanical and
electrical interconnections, and gas handling for hydrogen/oxygen, as well as completing Hazard and Operability (HAZOP) safety studies.
This detailed design is completed and will serve as the blueprint for constructing our first multi-panel hydrogen generation system and
establishes a framework for future scale-up to “hydrogen farms” of hundreds of panels.
