A Brazilian project which presents revolutionary features is about to change the way ships travel across oceans through its creation of the JAQ H2. This 50-meter ship operates at sea and generates green hydrogen fuel for its own needs. The project which Grupo Náutica and the Institute for Technological Research (IPT) developed will create an energy-independent system that eliminates all carbon emissions while developing new methods for naval engine operation.
The JAQ H2 which is now being built in Guarujá, in the state of São Paulo, will reach its operational status in 2027. The new system represents a major technological advancement from the previous model which used 36-meter JAQ H1 to demonstrate hybrid propulsion and achieve an 80% CO2 emission reduction during COP30. The H2 system will generate hydrogen through its onboard electrolysis system which uses water as its input. The hydrogen gas produced through this process will power the ship engines which produce only water vapor as their emissions.
The president of Grupo Náutica, Ernani Paciornik, declared that the company is developing its business from an experimental stage into a sustainable operational system which can generate profits. The project solves an essential problem which hinders the shipping industry from achieving its decarbonization goals because the industry depends on diesel engines and its operations need diesel fuel for extended distances and its battery systems have weight constraints. The JAQ H2 system produces its own fuel, which removes the requirement for outside fueling, while it also helps Brazil lead worldwide maritime energy transformation efforts.
The 125-year history of IPT in applied science will provide essential support for both testing the electrolysis system and maintaining secure hydrogen storage during actual navigation operations. The project includes a strong partnership network which consists of global manufacturer GWM, SENAI Pernambuco, and Porto do Açu in Rio de Janeiro, which functions as an essential testing center and research facility.
The JAQ H2 project which has potential to bring revolutionary changes remains in its experimental phase. The project faces technical challenges because hydrogen has low energy density which demands special storage systems and the team must find ways to improve electrolysis and reconversion process efficiency. The technology needs additional research to achieve both commercial viability and scaling capacity according to current requirements. The project establishes a definite path toward future navigation because it focuses on developing new vessel designs that optimize energy usage while decreasing harmful emissions.
