Monthly mean carbon dioxide content of the atmosphere globally averaged over marine surface sites, corrected for the average seasonal cycle*

2-3% of the global greenhouse gas emissions are caused by the use of fossil fuels in the maritime sector!

SES – HyDepot is developing the key technology for operating large scale vessels by means of CO₂-emission-free generated hydrogen. By this system most of the climate and health-damaging emissions from the maritime sector could be avoided.

SES – HyDepot is a start-up company, founded in 2013.

SES - HyDepot has received a funding from the Austrian Wirtschaftsservice (AWS) in 2017 for the realization of a first prototype of the patented technology.

SES - HyDepot has initiated the project HyMethShip, funded by the European Commission. This project involves renowned partners from the ship and engine building industry, has started in 2018 and is aiming to realize a ca. 1 MW demonstrator-plant. Within this project SES is responsible for the development of the process design.

Our Mission

The space and energy-efficient, large scale storage of hydrogen, independently of location, is currently still a fundamental problem for the far-reaching changeover of the current energy system towards fluctuating renewable energy sources (wind and solar power). By the development of a hydrogen storage system, SES intends to overcome this fundamental problem.

By this storage system, SES - HyDepot will open the possibility to ship operators and the society to run also large scale vessels with high energy consumption on renewable energy and thereby to avoid the emissions of different pollutants*.

Our Process

The process developed and patented by SES - HyDepot allows to store hydrogen space efficiently in the form of methanol. The high energy efficiency of this process is based inter alia on the fact, that the carbon dioxide, generated during the release of hydrogen, is stored within the process and can therefore be used for the synthesis of new methanol.
