Overview

Green hydrogen production must scale up significantly to achieve our net-zero ambitions. However, the water electrolysis (WE) market is a challenging operational landscape.

Engineers must solve the “system dilemma” of optimizing performance, safety and durability  — where strengthening one vector means compromising on the others. 

GORE® PEM for Water Electrolysis M275.80 breaks through performance barriers by optimizing all three vectors at the same time.

Our advanced membrane achieves new levels of hydrogen electrolysis efficiency and scalability, lowering the levelized cost of hydrogen (LCOH).

For almost three decades, we've led the market in producing proton exchange membranes (PEM) for fuel cells.

Today, our state-of-the art production facilities and enterprise capabilities are available immediately to support multi-gigawatt water electrolysis systems.

Advantages of GORE PEM for Water Electrolysis

Water electrolysis OPEX must be reduced to achieve the LCOH necessary for large-scale WE commercialisation.

Our advanced material attributes tackle technology trade-offs, improving stack efficiency, reducing hydrogen plant operating expenses and mitigating risks in hydrogen production.

Expert insights on the global clean energy ecosystem >

From products to partnerships, there are many factors to consider between different electrolysis technologies.

Gore believes each one has an important role to play in the water electrolysis ecosystem to accelerate the clean energy transition.

Proton Exchange Membrane (PEM)

AttributesTechnology Readiness Level (TRL)

Positive

  • Low OPEX (due to higher efficiency)
  • Most ‘flexible’ in application:
    • Operates effectively at variable power levels (including low current density) making it suitable for intermittent, renewable energy sources.
    • Has low gas permeability even at low current densities, allowing a wide operating range and enabling continuous hydrogen production.
  • Smallest footprint, enabling higher overall system design flexibility (e.g., offshore applications)
  • Highest hydrogen gas purity 
  • H2 output already pressurized, eliminating the need for an additional compressor 
     

Negative

  • Noble metal catalyst material
TRL 8 and 9 indicates proven performance in many industry applications

Alkaline (ALK)

AttributesTechnology Readiness Level (TRL)

Positive

  • Low CAPEX (low-cost materials)

Negative

  • Slow cold start (vs. PEM)
  • Low dynamic operation (must be shut down at low current densities
  • Caustic, liquid electrolyte
  • H2 output comes at atmospheric pressure
TRL 9 indicates most mature, widespread and scaled technology

Solid Oxide (SOEC)

AttributesTechnology Readiness Level (TRL)

Positive

  • Highest electrical efficiency

Negative

  • Least flexible
  • Limited deployment
  • Limited stack life
  • Very high temperature operation (>750 °C)
TRL 7-8 indicates advancing readiness and prototypes in the market

Anion Exchange Membrane (AEM)

AttributesTechnology Readiness Level (TRL)

Positive

  • Very flexible + highly efficient technology with small footprint and low OPEX
  • Low CAPEX (no noble metal catalyst materials)
  • Lower alkalinity than ALK

Negative

  • Low stack life and small-scale deployment
TRL 5-7 indicates that technology is in early stage project development
