World’s First Hydrogen And Battery-Powered Submarine Can Clean Oceans By Collecting Microplastics While Transporting Cargo

Company Develops The First Submarine In The World Powered By Hydrogen And Battery. A Fleet Of The Model Can Reduce 27 Tons Of CO2 During Cargo Transport

In September, Grant Shapps, UK Secretary of State for Transport, announced 55 winning projects from an ecological maritime R&D competition. Among the projects was the world’s first sustainable submarine. The fully automated “positive liquid” submarine was named Emerald 01, being entirely powered by green hydrogen and a battery. The submarine can help clean the oceans by collecting microplastics during cargo transport.

Submarine Fleets Can Reduce Up to 27 Tons Of CO2 Per Year

The hydrogen-powered submarine features a three-phase microplastic filtration system. Oceanways, its developer, is preparing the project for its pilot route between Belfast, Northern Ireland and Glasgow, Scotland. According to the company, a fleet of these hydrogen submarines could ensure a savings of up to 27 tons of CO2 emissions during cargo transport in its inaugural year, with a goal of reducing 300 million tons of CO2 as the fleet expands.

According to Dhruv Boruah, CEO and Founder of Oceanways, time is running out, and it is imperative not to settle for just 1% more efficiency in an existing system, but instead to rethink from other angles so that innovative solutions can be discovered.

According to the company’s CEO, Oceanways has assembled a world-class team to lead SubZero, creating a new market for positive underwater cargo transportation systems using zero-emission battery and hydrogen submarines as an innovative tool to clean the ocean and decarbonize cargo transport.

Projects to Clean Oceans Advance and Seek Investments

In addition to the hydrogen-powered battery submarine that cleans the sea during cargo transport, another project gaining attention is a fully electric charging point connected to an offshore wind turbine.

The points will serve to supply electric boats using 100% clean energy generated by the turbine, offering a potential savings of 131,100 tons of annual CO2 emissions. Equivalent to removing 62,000 combustion cars from the roads.

Similar to electric car charging points, these will be operated by semi-automated control, meaning sailors can dock their ships at the wind turbine charging point and charge them.

Brazil Advances With Use of Nuclear Sources in the Navy

In the interior of SP, the Brazilian Navy is about to test the first submarine powered by nuclear technology, which has been entirely developed within the country and is part of the project to renew the Brazilian submarine fleet.

The engine uses a technology mastered by only six countries. The entire engine is being created in full size for the possibility of simulating reactor operation and making precise modifications before the engineers finalize construction.

The technology will be installed on the last of the five underwater vehicles being built in Rio de Janeiro. The first nuclear-powered engine is expected to start operations in a submarine later this year, with deliveries scheduled by 2034.
