Hydrogen-Producing Boat

Energy Observer is the first oceangoing vessel that is totally energy self-sufficient. It draws from wind, solar, water, and fuel cell power – and even produces its own hydrogen from seawater.

The developer started with an award-winning catamaran and equipped it with cutting-edge technologies to harness all of its power from nature. Solar cells cover the vessel top and bottom to collect light not only from above, but also as it is reflected off the water. The power from these is stored in lithium-ion batteries for short-term use during the day. Excess energy is used to power an onboard electrolysis system that converts seawater into hydrogen gas, which can be compressed and stored until it is needed. In addition, Energy Observer’s specially designed sails are twice as efficient as traditional sails, reducing overall energy needs by as much as 40 percent.

The proof-of-concept vessel began its trip around the world in 2017 in an effort to demonstrate that decarbonized and decentralized energy is achievable, and last year logged a record 10,000 miles. The crew hopes to complete their journey in 2023.
