Our comprehensive hydrogen solutions encompass grid to stack systems that connect high-voltage grids to hydrogen production system, zero-emission generators powered by hydrogen, and an integrated supply-demand control system currently under development, to establish robust infrastructure for hydrogen production, transportation, and usage.

These technologies aim to accelerate the development of green hydrogen by enabling stable, scalable, and cost-effective production, storage, and utilization. By resolving temporal and spatial mismatches between renewable energy generation and energy demand, they support decarbonization across industries and regions, and contribute to building a resilient and sustainable energy infrastructure.

The solution integrates multiple hydrogen technologies to deliver flexibility, scalability, and efficiency across the energy value chain:
- Grid-to-Stack provides a complete high-voltage power interface for hydrogen production, offering end-to-end engineering support, grid connection expertise, and asset health monitoring to accelerate deployment.
- HyFlex™ is a portable, zero-emission hydrogen generator designed for flexible electrification in off-grid or temporary environments, featuring plug-and-play scalability and clean operation.
- Energy Storage and Supply includes low-cost green hydrogen production and multi-grid management capabilities that coordinate electricity and hydrogen, optimize supply-demand balance using simulation technologies, and leverage existing gas infrastructure for low-cost hydrogen transport and separation.

Together, these features enable seamless integration of hydrogen into diverse energy systems, supporting both centralized and distributed applications.

- Accelerated deployment of hydrogen infrastructure through streamlined grid connection and system integration, reducing project lead times and complexity.
- Enhanced energy resilience by enabling long-duration storage and on-demand clean power, supporting both centralized and distributed energy systems.
- Cost reduction in green hydrogen production and supply by leveraging surplus renewable energy and existing gas infrastructure.
- Balanced energy distribution across regions and time, mitigating supply-demand mismatches and contributing to grid stability.
- Environmental impact reduction through zero-emission power generation and support for decarbonization in hard-to-abate sectors.
