HB Marine and Independence Green Yachts yesterday announced a partnership that will form a joint venture to develop the Independence 60 Luxury Yacht that IGY started a few years ago. The Independence 60 is billed as the “world’s first ‘no compromise’ sustainable yacht.” A combination of solar cells, hydrogen production and storage and fuel cells provide complete independence from fossil fuel.

Here’s what the two companies had to say yesterday:

“The partnership between HB Marine, owner of a patented technology for the production, storage, and use of hydrogen aboard marine vessels, and Independence Green Yachts, developer of the solar/hydrogen powered Independence 60 power yacht, is a very compelling and timely combination. The joint venture will offer the marine industry fully integrated and self sustainable yachts (like the Independence 60) as well as clean energy power and propulsion systems for new construction and retrofits of existing yachts.

IGY is the developer of the Independence 60, the first totally self-sufficient, solar/hydrogen powered motor yacht that requires no fossil fuels or internal combustion engines. “Building a sustainable boat that can cruise cleanly, quietly and without ever having to use fossil fuels has been my dream since the Navy,” said Fred Berry President of IGY. “In conjunction with HB Marine, we can make this dream a reality.”
 
HB Marine has developed and patented internationally, a hydrogen-based, multi-use power and propulsion system for all types of marine vessels using readily available technology. “We have been searching for the right marine partner to bring this clean technology to market. The unique design of the Independence 60 effectively integrates the best of clean energy marine power and propulsion technologies , which will open a new era of simple, clean, quiet, reliable and sustainable yachting,” said Bruce Wood, Managing Director of HB Marine.”

The power system for the Independence 60 represents the very cutting edge of energy generation, storage and management. To-date, that title has been held by Island Pilot’s DSe Hybrid, developed by Reuben Trane. The DSe has the solar cells and vertical wind turbines, but still relies on a diesel engine/generator to recharge the batteries on cloudy days or when energy usage exceeds a little more than 6 kW. The Independence 60 has twin azimuthing electric motors. The system takes electricity from the solar arrays, or from the battery bank, and uses an electrolyzer to separate pure water from a watermaker (or, downstream in the process from a fuel cell)  into molecular hydrogen, which is then stored in a room-temperature, normal atmosphere metal and then provided upon demand to a fuel cell, which will generate a lot more electricity to replenish batteries, or to provide power to an inverter, and through a service panel to the electric motors.

Here is a simplified diagram of the power system aboard:
