About Pherousa
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.
Pherousa Green Technologies (PGT) AS is Norwegian technology transfer company within the maritime industry. PGT develops its own technology and also offers consulting services to help our customers navigate through the transition to ZERO emissions. For inquiries on our services and technology please contact us and we will get in touch with you.
PGT is continuously developing advanced solutions for efficient and ZERO emission shipping. A key measure of the feasibility of zero-emission shipping is whether ships can carry enough fuel to service existing legs and voyages, with hydrogen being the only realistic option for ZERO emissions, this is a challenge. Due to hydrogen's low volumetric energy density storing hydrogen for voyages longer than a couple of days is a major challenge. In addition bunkering infrastructure for hydrogen does not exist. On the other hand, as of today, there are 120 ports equipped with ammonia trading facilities. 1 mol of ammonia contains 1.5 mol of hydrogen, which is 17.8% by weight or 108 kg of hydrogen per cubic meter embedded in liquid ammonia at 20 C. Comparing this to the most advanced hydrogen storage systems, e.g. metal hydrides, which store 25 kg of hydrogen per cubic meter, the advantage of ammonia in carrying hydrogen per unit volume is significant.
Therefore bunkering ammonia and cracking to hydrogen on board a vessel can solve the storage and infrastructure challenges of hydrogen as marine fuel paving the way to ZERO emission shipping with today's technology.
PGT has developed an ammonia cracker, able to crack ammonia to hydrogen of fuel cell quality according to ISO 14687:2019. The ammonia cracker is based on the proprietary and patented Heat Integrated Wall Reactor (HIWAR) developed by our partner and shareholder HELBIO S.A.
Ammonia cracking to hydrogen on board a vessel can help shipowners to minimize the investment risk when installing propulsion systems to be carbon-free. By choosing hydrogen fuel cells as the propulsion system with an ammonia cracker, the shipowner can start with ammonia and switch to hydrogen at any time with minimum investment risk. In that manner, using ammonia as a hydrogen carrier facilitates the efforts for opening up the path to trade ammonia as a fuel in addition to a chemical commodity for the chemical and fertilizer industry.
