HyPanel-S is a compact hydrogen refueling panel developed by HySol for controlled, manual hydrogen refueling operations using the cascade filling method.

The panel integrates pressure regulation, monitoring, purging, and pressure relief functions into a compact unit. It can be installed as a standalone mobile solution or integrated directly into existing hydrogen storage and refueling infrastructure.

Key technical features

Maximum inlet pressure: 400 barg

Adjustable outlet pressure: 30–350 barg

Maximum hydrogen flow rate: <120 g/s

Operation: Manual cascade refueling

Integrated pressure regulation: Adjustable mechanical pressure regulator

Pressure monitoring: Two analog gauges for inlet and regulated outlet pressure

Purging and venting: Dedicated line for nitrogen purging and residual hydrogen venting

Overpressure protection: Dedicated pressure relief line with safety relief valve

Materials: AISI 316L stainless steel hydrogen-wetted components

Electrical supply: Not required

Operating temperature: −20 to +40 °C

Dimensions (W × H × D): 700 × 600 × 200 mm

Weight: 35 kg

Installation Options

HyPanel-S is available in several configurations:

Mobile: Mounted on a movable steel frame
Wall-mounted: Fixed installation on a wall
Trailer-mounted: Integration with hydrogen transport trailers
MEGC-mounted: Installation directly on Multiple Element Gas Containers
Container-mounted: Integration with containerized hydrogen storage systems

Refueling Connections

HyPanel-S supports different hydrogen refueling interfaces according to customer requirements:

H35/H35HF-compatible hydrogen refueling nozzle, with interfaces according to SAE J2600 / ISO 17268
Flexible high-pressure hydrogen hose with customer-specified end connection

Hose length, connection types, and connection arrangements can be customized for the intended application.

Operation and Applications

The system operates without electrical power or automated control. Hydrogen pressure is regulated mechanically, while the operator manually controls the cascade refueling process.

Typical applications include hydrogen vehicle refueling, integration with hydrogen storage systems, trailer- and MEGC-based refueling, temporary hydrogen infrastructure, and pilot projects.
