KOTUG selects EST-Floattech’s battery system for electric pusher tug

Dutch towage and maritime company KOTUG International has chosen EST-Floattech’s containerized energy storage solution with Octopus Series for the E-Pusher 1, an electric pusher tug.


The Octopus Energy Storage System has been specifically designed for maritime needs, including fully electric and hybrid propulsion. EST-Floattech’s team has been working on the containerized solution with Octopus High Energy modules. The container was designed and constructed in a little over half a year.

This containerized solution will provide the energy that allows the E-Pusher to make about three trips from Zaandam to Amsterdam and back, according to EST-Floattech.

The partnership with EST-Floattech signifies our commitment to innovation and sustainability. With the world’s first fully electric pusher boat powered by EST-Floattech’s technology, we are setting a new standard for emission-free maritime transportation,” Ard-Jan Kooren, CEO & President KOTUG said.

“We are proud that we have been given the chance to create this containerized energy storage system for KOTUG and contribute to the world’s first emission-free and fully electric pusher tug,” Walter van der Pennen, Commercial Director at EST-Floattech added.

KOTUG recently signed a framework agreement with compatriot shipbuilding and ship repair specialist Padmos to build ‘the complete lineup’ of E-Pusher, an electric pusher tug.

The E-Pusher series embodies advanced technology and propulsion systems, establishing a new standard in emission-free navigation. The vessels are equipped to eliminate harmful emissions, including carbon dioxide (CO2), sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM).
