SES - HyDepot e.U.

SES - HyDepot e.U. is an Austrian sole-proprietorship (Einzelunternehmen) technology company that works under the public-facing name "SES : Ship Emission Solutions". It develops hydrogen storage and hydrogen fuel technology aimed at eliminating the climate- and health-damaging emissions produced by the maritime shipping sector. The company frames its mission around a fundamental problem of the energy transition: storing large quantities of hydrogen in a way that is location-independent and sufficiently energy- and space-efficient to power large, high-energy-demand ships from fluctuating renewable sources such as wind and solar power. The company's central technical proposition is a patented hydrogen storage system. According to its own account, SES - HyDepot received a PreSeed grant from the Austrian Wirtschaftsservice (AWS) in 2017 to build a first prototype of that patented technology. From 2018 to 2021 the sole proprietorship acted as initiator and project partner in HyMethShip, a project co-financed by the European Commission and involving well-known partners from the shipbuilding and engine-building industries. The project pursued the realisation of a demonstrator plant of roughly 1 MW, and SES - HyDepot was responsible within it for developing the process-engineering procedure. The company positions hydrogen produced without CO₂ emissions as the route to operating high-performance ships, arguing that a large share of shipping-sector emissions can thereby be avoided in future. Its stated ambition extends beyond shipping to opening a new path for shipping companies and for society to run even large-scale, high-energy-demand vessels on renewable energy. The firm is small and engineering-led, operating as a project partner and technology developer rather than as a shipbuilder or fuel supplier. Its public identity is bound up with the ship-emission.solutions domain and the SES - HyDepot name, and it is recorded as an entity in Wikidata. Because it is a sole proprietorship rather than a listed or group-owned company, its ownership and financial details are not publicly disclosed in the available evidence.

SES - HyDepot e.U. is an Austrian sole proprietorship (Einzelunternehmen) that operates publicly as "SES : Ship Emission Solutions". Its history, as documented on its own website, is short and project-centred, organised around the development of a patented hydrogen storage technology and participation in a European research project. In 2017 the sole proprietorship received a PreSeed grant from the Austrian Wirtschaftsservice (AWS) to build a first prototype of its patented technology. This grant marks the earliest dated event in the company's own account and indicates that the patented hydrogen storage concept was already in place at that point. From 2018 to 2021, SES - HyDepot e.U. acted as initiator and project partner of HyMethShip, a project co-financed by the European Commission. HyMethShip brought together well-known partners from the shipbuilding and engine-building industries and pursued the realisation of a demonstrator plant of approximately 1 MW. Within the project, SES - HyDepot was responsible for developing the process-engineering procedure. This period represents the company's principal documented activity: contributing process engineering to a multi-partner European demonstrator rather than commercialising a standalone product. The company's stated mission is to solve what it describes as a fundamental problem for the broad conversion of the energy system to fluctuating renewable energies (wind and solar): the location-independent, sufficiently energy- and space-efficient storage of large quantities of hydrogen. SES - HyDepot states that its hydrogen storage system is intended to open a new path for shipping companies and for society to propel even large-scale ships with high energy demand using renewable energy, thereby avoiding a large part of the climate- and health-damaging emissions in the shipping sector. The company cites the fact that 2–3% of global greenhouse gas emissions are caused by the use of fossil fuels in the shipping sector as the context for its work. Beyond these dated events, the available evidence does not record founding year, founder, headquarters location, ownership structure, funding rounds, customers, or commercial deployments. The company remains an active, small, engineering-led entity whose public profile rests on the HyMethShip participation and its patented storage technology.
