Purification That Meets Fuel-Cell Standards

Not all hydrogen is ready for the road. To power trucks and material handling equipment, hydrogen must meet strict purity standards that protect fuel cells and keep fleets running reliably. ESSNA™ pairs on-site generation with industry-leading purification technology, delivering consistent, >99.99% pure hydrogen that’s safe for every fill.

Why Purification Matters

Protects Fuel Cells from Damage

Purification removes carbon monoxide, sulfur, and other impurities that can poison fuel cells, preventing costly damage and extending equipment life.

Keeps Fleets Running Reliably

Consistently pure hydrogen keeps trucks and forklifts operating at full power every shift, reducing downtime and keeping schedules on track.

Reduces Total Cost of Ownership

By preventing degradation and minimizing maintenance needs, purified hydrogen lowers the total cost of ownership and maximizes ROI on your fleet.

Meets Compliance Standards

Every fill meets strict SAE J2719 and ISO 14687 standards, ensuring your fleet stays compliant, warranty-protected, and future-ready.

On-Site Purification

How We Deliver Fuel-Cell Grade Hydrogen

ESSNA™ integrates purification directly into our on-site generation systems. Advanced filtration and separation technologies remove carbon monoxide, carbon dioxide, sulfur, and particulates — ensuring every kilogram meets SAE J2719 and ISO 14687 standards. The result: hydrogen that’s clean, consistent, and ready for fuel-cell fleets.

Frequently Asked Questions

What fleet operators ask us most.

1. Do I need to replace my fleet to use hydrogen?

No. Our hydrogen-diesel blend works with your existing diesel engines, so there’s no need to invest in new vehicles to start reducing emissions and fuel costs.

2. How much does the system cost to install?

Nothing upfront. ESSNA™ covers the cost of installation and setup. You only pay for the hydrogen fuel you use.

3. How is the hydrogen produced on-site?

Our units generate hydrogen using electrolysis or natural gas reforming, depending on your site setup. The system is fully self-contained and optimized for fleet yard operations.

4. What if my operations can’t afford downtime?

Our system includes 24-hour fuel reserve storage and real-time monitoring — we guarantee uptime and handle all maintenance.

5. Can I qualify for carbon credits or low-carbon fuel incentives?

Yes. Using a hydrogen-diesel blend or switching to hydrogen can significantly lower your fleet's carbon intensity, making you eligible for government incentives or carbon credits.
