H2Mare - DACMA awarded contract to establish DAC units offshore

We are delighted to have received an order from the Karlsruhe Institute of Technology (KIT) to integrate our DAC unit into an offshore Power-to-X platform for the H2Mare project.
The project H2Mare is funded by Federal Ministry of Education and Research:

Offshore wind turbines generate significantly more regular electricity than their onshore counterparts. The H2Mare hydrogen flagship project aims to utilise this potential by using
renewable electricity directly at sea to produce hydrogen and hydrogen derivatives like e-Kerosene, LNG, methanol or ammonia. In the scope of the H2Mare PtX-Wind project, a transportable floating experimental platform (picture) will be built on which a multistep Power-to-liquid (PtL) process will be placed for experimental testing at sea. The process, which makes use of two existing transportable process equipment containers, consists of several steps, i.e.

• capturing CO2 from ambient air by DACMA GmbH
• producing ultrapure water for electrolysis from sea water
• producing synthesis gas from CO2 and ultrapure water either via the so-called hightemperature
co-electrolysis
• or steam electrolysis followed by CO2 conversion with hydrogen according to the
reverse water gas shift reaction (RWGS)
• Fischer Tropsch Synthesis (FTS)
• FT syncrude upgrading to synthetic paraffinic kerosene (SPK)

The initial tests will be carried out in the PtX Lab being part of the Energy Lab at KIT North campus, and later similar tests will be carried out on Germany’s territorial water in the North Sea near Helgoland in the summer of 2025. The FTS requires CO2 as the input stream for which extraction of CO2 directly from air (DAC) is the only viable option at the intended scale of round about 100kg per day. Therefore, a DAC plant from DACMA GmbH will deliver CO2 for the following Co-electrolysis or RWGS units. This is the first time that a DAC unit has been operated offshore.
