H₂opZee Demonstration Project

Project Name: H₂opZee Demonstration Project – Appraise & Select phase
Client: Neptune Energy (Eni) & RWE
Location: Dutch North Sea

Project overview

H₂opZee is a pioneering demonstration project evaluating the feasibility of producing green hydrogen at sea, powered by offshore wind. The project explores various scenarios for offshore hydrogen production and investigates options for transporting the hydrogen to shore via pipelines. This initiative is part of a broader effort to advance renewable energy and large-scale hydrogen production.

Enersea and sister company H2sea were awarded critical roles for the feasibility and concept design.

The role of Enersea

Pipeline Concept Design

Pipeline Sizing, Routing, and Design

Developing sizes, routes, and designs for new pipelines.

Infrastructure Analysis

Exploring scenarios for hydrogen integration within the offshore network.

Design Methodologies

Providing guidance on safe, efficient hydrogen transport.

The role of H2sea

Hydrogen Platform Concept Design

Platform Design Considerations

Addressing electrical systems, processing, utilities, and safety.

Constructability and Installation

Ensuring practical design choices for offshore conditions.

Hydrogen Production Strategy Selection

Advising on the optimal hydrogen production approach after a comprehensive investigation of central, decentral, and intermediate options.

Electrical Grid Studies and Analyses

Conducting in-depth studies on grid stability and integration, with innovative solutions aimed at reducing the required energy storage capacity, thereby lowering the cost of energy storage components.

Project Significance

The feasibility studies and concept designs bring Neptune Energy (Eni) and RWE closer to defining the H₂opZee demonstration project, establishing a viable approach for offshore green hydrogen production and transport.

Stage 2+ Project – A15 & B10 Development for Petrogas

Due to its expertise in developing small and economically challenging gas fields, Enersea was awarded the Front-End Engineering Design (FEED) directly by Petrogas and the Detailed Design contract through a close cooperation with HSM.

Riser and Pipeline Design Electrified Gas Production Platform N05-A

The N05-A project will be a groundbreaking offshore gas production platform, to be situated in the Dutch sector of the North Sea and developed by ONE-Dyas.
