Advent Technologies and Technohull team up to design and produce an innovative electric vessel that uses eMethanol-powered fuel cell systems

BOSTON, MA. – October 10, 2023 – Advent Technologies Holdings, Inc. (NASDAQ: ADN) (“Advent” or the “Company”), an innovation-driven leader in the fuel cell and hydrogen technology sectors, and Technohull, a leading manufacturer of high technology and high-performance luxury boats headquartered in Lavrio, Greece, have announced an agreement to collaborate on the development of a hybrid and environmentally-friendly electric propulsion system.  This system will utilize Advent’s eMethanol-powered fuel cells (“Serene”) and batteries to provide a reliable and efficient electricity supply for a specially designed Technohull vessel.

The initial focus is to integrate Advent’s Serene systems into a Technohull boat to achieve a significant range, at planing speed, and in open sea conditions. The compact battery that will be integrated as part of the project will be notably smaller than what would typically be required for a traditional battery-only solution to achieve the same range. This will significantly lower the Total Cost of Ownership, compared to a battery-only solution. Advent’s Serene systems will use eMethanol, which is derived from green hydrogen and captured carbon dioxide and will therefore generate net-zero emission electricity.

Advent’s SereneU solution, a 4th generation eMethanol-powered hydrogen fuel cell that will be used, can be configured to provide power of up to 250kW.  Advent’s Serene systems produce low noise and vibrations, therefore allowing passengers to avoid exposure to the typical engine noise, vibrations, and exhaust odors associated with motor vessels, creating a more comfortable and peaceful experience.

eMethanol has gained significant traction as a potential green fuel for the maritime industry due to its high energy density, ease of handling and low emissions.  As the maritime industry looks to reduce its carbon footprint and comply with increasingly strict environmental regulations, eMethanol has emerged as a promising alternative to traditional fossil fuels.

Dr. Vasilis Gregoriou, Chairman and CEO of Advent Technologies commented: “At Advent, we are seeing more demand for our eFuel-powered systems in the maritime industry.  Our products can significantly reduce emissions and help the industry comply with strict environmental regulations by eventually driving emissions to zero.  We believe in eMethanol’s role as an accelerator to the decarbonization of the maritime industry, and we are excited to collaborate with Technohull in this ambitious project.”

Mr. Gerasimos Petratos, CEO of Technohull commented: “We are thrilled to be partnering with Advent Technologies on this innovative project which will utilize Advent’s eMethanol-powered fuel cells (“Serene”) to provide a green, reliable and efficient electricity supply for a Technohull vessel. Having always been a pioneering company, we constantly invest in high technology, innovation, and R&D and thanks to our state-of-the-art hull design technology, we design and produce extremely efficient hulls that manage to offer top-notch performance on the water with less energy consumption. Our industry along with the rest of the world is striving for more sustainable solutions, and Technohull cannot possibly remain inactive. Our collaboration with Advent and the implementation of this hybrid solution showcases our commitment to sustainable and environmentally friendly practices. Technohull has always been dedicated to leverage from cutting-edge technologies, in order to drive progress in the maritime industry and we strongly believe that this partnership will help us move in the right direction.”
