ENERGY STORAGE

Long-Duration Energy Storage via Power-to-Gas

Name: IONZERA Gas Separator Membrane
Brand: IONZERA
Availability: InStock
Rating: 4.8 (12 reviews)

Seasonal and weekly renewable energy storage requires power-to-gas systems. IONZERA's ultra-low resistance maximizes the round-trip efficiency of converting electrons to molecules and back.

Higher Round-Trip Efficiency

Every millivolt of reduced cell voltage improves the power-to-gas round-trip efficiency. IONZERA's 3x lower membrane resistance saves approximately 0.08V per cell, directly improving the economics of stored energy.

Dynamic Load Following

Power-to-gas systems must respond to variable renewable generation. IONZERA's high wettability and optimized pore structure support rapid load changes without performance degradation.

Cost-Effective at Scale

Long-duration storage requires large electrolyser capacity. IONZERA's mesh-free, India-manufactured membranes offer competitive pricing for the high volumes that grid-scale storage demands.

The Need for Long-Duration Energy Storage

As renewable energy penetration increases beyond 50-60%, power grids face growing challenges with seasonal and weekly supply-demand mismatches that batteries cannot economically address. Power-to-gas (PtG) systems convert surplus renewable electricity into hydrogen or synthetic methane, which can be stored in existing gas infrastructure and reconverted to electricity or used as fuel weeks or months later.

The electrolyser is the heart of every PtG system, and its efficiency determines how much stored energy can be recovered. IONZERA's ultra-low area resistance maximizes the electrolysis step efficiency, preserving more of the original renewable energy through the storage cycle.

Electrolysis Efficiency in Power-to-Gas Systems

In a PtG system, the electrolyser converts electrical energy to chemical energy stored in hydrogen. The membrane's contribution to cell voltage losses directly reduces the storage efficiency:

IONZERA's membrane voltage drop of approximately 0.04V at 0.4 A/cm2 versus Zirfon's 0.12V saves significant energy in every operating hour

Over thousands of hours of annual operation, these savings accumulate into substantial improvements in system-level round-trip efficiency

Lower membrane losses also mean less waste heat, reducing cooling system requirements and parasitic loads

The thin 350-410 um profile contributes to more compact electrolyser stacks, important for space-constrained grid infrastructure sites

Grid Integration and Flexibility

Power-to-gas electrolysers must handle highly variable load profiles, ramping up when renewable generation exceeds demand and reducing output or shutting down during low-generation periods. IONZERA's high wettability with a 24-degree contact angle ensures the membrane remains fully wetted even during rapid load transitions, maintaining consistent ionic conductivity across dynamic operating conditions.

G-Hexa works with power-to-gas system integrators and grid operators to optimize membrane selection for their specific operating profiles and storage requirements.
