      The challenges of the REXH2

      While the crew of Energy Observer continues to navigate the Atlantic without being able to set foot on land, another team is holding its breath: that of Energy Observer Developments (EODev), whose REXH2 is currently sailing on the first hydrogen vessel around the world.

      The EMS: Energy management system

      This is the brain of the vessel’s energy supply. Combining multiple intermittent renewable energy sources and storage is one thing. Optimising their use to propel the boat and ensure the crew’s comfort is another! This is where the Energy Management System (EMS) comes in.

      Energy Observer propulsion

      Energy Observer is propelled by two electric motors, each with 42kW, providing a total of 115 horsepower. The motors, designed by Phase Automation, have very high output (97%), which also contributes to reducing the boat’s energy requirements.

      The hydrogen chain step 3: The Energy Observer compression

      Hydrogen has a very high energy content: for the same weight, it contains up to three times more energy than diesel, and 2.5 times more than natural gas. That said, we know how to store natural gas in tanks or pipelines. Storing hydrogen is more difficult.

      The hydrogen chain step 2 : the Energy Observer electrolyser

      Currently, 95% of the world’s hydrogen supply is from fossil fuel, through a reforming process using methane, the main component of natural gas. Electrolysis using a renewable energy source is a solution for the future use of green hydrogen on a large scale.

      The hydrogen chain step 1: the Energy Observer watermaker

      The Energy Observer is equipped with a reverse-osmosis desalination system with several levels. When two volumes of water – one salty and the other not – are put together, natural movement is created: the fresh water is attracted to the salty water.
