ADI evaluated the market for carbon paper gas diffusion layers (GDL) within the rapidly expanding PEM electrolyzer supply chain. The research assessed the technical transition from titanium porous transport layers and modeled the impact of rising current density on future material demand. High and low cases accounted for green hydrogen production targets and announced OEM manufacturing capacities over a 10-year period.
The client
Private equity and materials producer
The situation
A producer required a market size estimate for specialized carbon papers to justify investment in new commercial-scale capacity.
ADI’s contributions
Voice-of-Customer research
Interviews with 35 experts across OEMs and developers confirmed the widespread replacement of titanium with carbon paper.
Analytical market sizing
Scenario modeling for market value over a 10-year period incorporated PEM efficiency, power density asymptotes, and expected price erosion.
OEM landscape mapping
Analysis of announced manufacturing capacity highlighted a potential shortfall in supply relative to national green hydrogen targets.
Adjacent growth identification
Technical analysis of PEM stack goals identified water treatment and gas purification as promising expansion areas for the client.
Key outcomes
- Justification of commercial-scale capacity expansion based on a projected annual growth rate in GDL demand.

CBAM puts a new price tag on emissions
On April 7, 2026, the European Commission announced the first official Carbon Border Adjustment Mechanism (CBAM) certificate price for Q1 2026 at €75.36 per tonne of CO2 equivalent (~$88/t CO2e), marking the EU’s first explicit carbon price applied to imported goods. This rate will be applied to the embedded emissions in CBAM-covered imports and is […]
Cooling fluids are becoming a constraint in AI data centers
Immersion cooling fluids are taking on more importance as data‑center operators deploy higher‑power artificial intelligence (AI) and high-performance computing (HPC) systems. Rack densities are increasing faster than traditional air systems can accommodate, and liquid cooling is now part of the design discussion for many new builds and retrofits. In that context, fluid properties affect reliability, […]
