Hydrogen Propulsion for a Truly Zero Emissions Deep Sea shipping - brought by Ammonia

Harnessing Hydrogen for a Greener Tomorrow

Welcome to Pherousa Green Technologies (PGT) – the forefront of zero-emission fuel solutions within the maritime industry. We are revolutionizing the seas by introducing the ultimate clean energy source: Hydrogen.

Hydrogen: The Pinnacle of Zero-Emission Fuel

At PGT, we understand the future of maritime transport lies in sustainability. Hydrogen, with its zero-emission profile, is the cornerstone of our vision. Navigating the challenges of hydrogen storage, we’re making deep-sea shipping cleaner and greener.

Ammonia: The Vanguard Hydrogen Carrier

Our groundbreaking ammonia-based technology offers a beacon of hope for carbon-free shipping. Ammonia, devoid of carbon in its molecular blueprint, emerges as the industry’s superior hydrogen carrier.

Innovative Ammonia Cracker Technology

PGT is proud to introduce our pioneering ammonia cracker, a leap forward in harnessing ammonia as a hydrogen source. Our cutting-edge approach is setting the stage for a sustainable maritime future.

A Flexible Hydrogen Supply for Diverse Needs (I have left pilot fuel just in case...)

The hydrogen produced by our state-of-the-art cracker is versatile, powering both fuel cells and serving as a pilot fuel for ammonia engines. This adaptability is reshaping the operational efficiency of vessels across the deep blue.

Proven Technical Feasibility

Our prototype has not only been realized but has demonstrated its practical potential. PGT is now transitioning from concept to market, ready to deploy our innovation on a global scale.

Elevating Our Vision with Strategic Partnerships

To amplify our reach, PGT is on the quest for strategic investors. In concert with TECO2030, we’re on the brink of crafting our first 400 kW pilot unit, marking a significant milestone in our journey.

Pilot Unit: A Beacon for Future Expansion

Our pilot unit is more than a testbed; it’s the crucible where we validate, refine, and perfect our technology. With each step, we’re building a sustainable maritime ecosystem, and we invite you to join us in this green revolution.

Pherousa Green Shipping

Truly zero emission cargo transport for the deep-sea segment

The only fuel that is truly zero emissions is hydrogen, but hydrogen storage is the biggest challenge for Deep-Sea shipping. Ammonia is the only hydrogen carrier that has no carbon in its molecule, therefore the only truly zero carbon hydrogen carrier.

Pherousa – she who carries –  is the name of two different figures in Greek mythology.
A Nereid, a sea nymph associated with the power of great ocean swells, helping sailors to face the challenges of the oceans, and a Horae goddess of substance.
