The H2Dock building system
The H2Dock hydrogen production building system consists of three distinct parts:
- a containerized module for Stacks and Balance of Stack equipment;
- a modular plant building system for Balance of Plant equipment and
- a docking module with interfacing connections for electrical, data/control, gas and liquid piping, facilitating the required interconnections between building blocks.
Our clients will build their equipment (Stacks, Balance of Stack and Balance of Plant) on removable skids which are placed in the containerised module or within the modular plant.
Onshore
The H2Dock building system is designed to create onshore hydrogen plants from 5 MW upto more than 1 GW. Above 40 MW the plant can be configured in steps of additional 40 MW, while economies of scale for the Balance of Plant are taken into account. This results in minimal land use and a low building volume.
Offshore
The same building system can be deployed offshore as well. Offshore options include smaller containerised hydrogen plants at the wind turbine or larger plants on centralised structures such as production platforms or FPSOs.
CONFIGURING, NOT ENGINEERING
Green hydrogen is new. Preferred technologies will change. Demands are vastly different, from decentralised 5MW plants to centralised Gigawatt plants. From turnkey systems to best-of-breed EPC-configured plants. Onshore and offshore. Innovation will be key. How to bring order to the chaos? By standardising as much as possible but not more. Equipment will change, but building systems should be standardised where possible. Larger plants will be configured with multiple standardised blocks of 40MW. The building system is such that the building volume does not grow linearly with the number of stacks in order to accommodate the economies of scale of the Balance of Plant.
THE DOCKING MODULE
The docking module provides the “coupling” between modules of gas and fluid pipes, electrical and data.
BENEFITS
A standardised and modular approach to building hydrogen production facilities, designed to lower the Levelized Cost of Hydrogen (LCOH). Allowing small turnkey systems by OEMs to large EPC constructed best-of-breed plants where the building-system is the same, while the electrolyser equipment is different as per customers' requirements.
Lower Capex
The H2Dock building system has a small footprint, low building volume and removable skids allow for an efficient build of the electrolysers. Standardisation allows for cost benefits by volume production.
Right-sourcing
Clear interfaces between components, skid based building blocks and fixed space allocations allow for easier outsourcing to the right vendors or in-house production at the right location.
Ready for innovation
The H2Dock building system allows for the easiest possible way to install, couple, decouple and remove components in order to allow operators to upgrade stacks or balance of plant components whenever this makes technical or economical sense.
Safety first
Protecting staff, hydrogen equipment and other installations is our primary goal in the design of H2Dock. Ventilation, safe venting and keeping hydrogen pipes outside confined spaces play a key role to minimise the frequency and duration of explosive environments.
Lower cost of maintenance
The H2Dock building system is designed for convenient maintenance at the right place: minor maintenance in the enclosure; for more involved maintenance, skids can be removed from containerised modules. For overhauls or exchanges, an entire containerised module can be removed and replaced, the latter being a unique and safe solution for expensive offshore maintenance.
Flexibility & speed
Because of the modularity of the system, a wide variety of customer demands can be configured from standard components instead of custom specific engineering. Front End Engineering and Design (FEED) and the building phase are much faster than with traditional approaches.

Who will use these H2Dock building systems ?
The H2Dock building system can be used by development companies who create hydrogen plants, by electrolyser OEMs who wish to develop turnkey hydrogen projects or by EPCs who want to develop best-of-breed production facilities, combining technologies from different specialised providers. Deployment can be onshore or offshore.
What is and what is not provided as part of the H2Dock building system?
An H2Dock building system provides the equipment enclosures (modified 45' "pallet-wide" containers and a modular Balance of Plant building system), the skids that will be placed in the container and the docking systems for coupling the various electrical, data, gas and fluid connections. The electrolyser equipment will be provided by other parties, such as electrolyser and stack OEMs or EPCs.
Is the H2Dock building system available as of today?
H2Dock has created the conceptual designs for the building system and verified these with several electrolyser OEMs for feasibility. In the next phase of the project, partially funded by the European Union, we will collaborate with multiple electrolyser OEMs and EPCs, engineer the system and validate the systems with various prototypes.
Development modular electrolysis
The development of the H2Dock modular building system for hydrogen production is for 50% funded by the European Union.
