The Innovations

Our ship of the future has finally returned to its natural element after 3 months out of the water and many improvements on its onboard technologies.

The first hydrogen vessel around the world has just started its winter technical stopover after 7 months of expedition to Northern Europe.

During the “Hydrogen, the Right Move at the Right Time” day, organized by AFHYPAC at the “Maison de la chimie”, Energy Observer announces the launch of Energy Observer Developments’ industrial activities, thus confirming its desire to deploy clean systems for everyone.

Energy Observer takes care of the details. The experimental catamaran optimizes all its systems to improve its performance as well as the crew’s comfort. Explanations by Roland Reynaud, the on-board engineer.

Do you know how much energy is consumed for a coffee? A tea? Preparing a pizza for 6 people? We tend to forget it, but each gesture of daily life, however simple it may be, requires energy, and often much more than we think!

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 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.

During the Monaco Solar & Energy Boat Challenge, Energy Observer announces the launch of Energy Observer Developments. The ambition of this new phase of the project is to propose disruptive, innovative, optimized and accessible solutions to various maritime and port communities.

To avoid losing the energy dissipated as heat, the Energy Observer engineers installed a recovery system for the heating and hot water used in the living quarters nacelle.

Energy Observer chose complementary storage systems: short-term storage in a set of Li-Ion batteries, and eight hydrogen tanks for long-term storage.

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.

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.
