Transforming Hydrogen Storage: Kivoro (GRAPHENEA) Graphene Redefines PA11 Barrier Performance
Graphene-enhanced hydrogen permeation barrier
Thinking about how to make hydrogen storage more efficient? At KIVORO (Graphenea), we are solving one of the toughest challenges in the hydrogen economy: gas permeation.
The transition to a Hydrogen Economy relies on one critical factor: Storage Efficiency. For Type IV hydrogen tanks, a major hurdle has always been the permeation of H2 through thermoplastic liners under extreme conditions.
We are excited to share breakthrough results from recent testing conducted by the Advanced Carbons Council on Kivoro’s graphene-enhanced PA11.
📉 The Results: A New Benchmark for Barrier Properties
Validated at 700 Bar, rigorous testing compared virgin PA11 against our graphene-modified formulations at room temperature:
- Significant Permeation Reduction: Graphene-enhanced materials achieved a reduction in hydrogen permeation of up to 63% compared to the virgin baseline,
- Enhanced Structural Stiffness: Beyond the barrier properties, the modification resulted in a stiffness (Modulus) increase of up to 32.9%, which is vital for maintaining liner integrity under high pressure.
🛠 Why This Matters for Type IV Tanks
By significantly slowing hydrogen transport through the polymer structure, Kivoro’s graphene additives directly contribute to:
- Increased Safety: Lower gas loss and reduced risk of accumulation.
- Longer System Lifetime: Improved material gas barrier performance and retention efficiency.
- Regulatory Compliance: Helping manufacturers align with international hydrogen test methodologies and safety standards like CSA/ANSI CHMC 2.
These findings confirm that material modification with graphene is a key enabler for the next generation of high-pressure hydrogen storage liners.
