COCOLIH2T Approach

COmposite COnformal LIquid H2 Tank

Project objectives

To achieve its goal COCOLIH2T will  complete and deliver  the following seven objectives:

Objective 1

MATERIAL SELECTION AND MATURATION

Down-select and mature the right materials for tank walls, Multi-Layer Insulation (MLI) and permeation barrier

Objective 2

DISRUPTIVE VESSEL CONCEPT and DESIGN

Design and develop a composite conformal LH2 tank, including thermal and pressure management

Objective 3

TANK MANUFACTURING

Manufacture the composite and conformal LH2 tank

Objective 4

TANK SUBSYSTEMS

Design and develop a tank refuelling, metering, gauging, and gas leak-detection system for safe system functioning

Objective 5

TANK HEALTH MONITORING SYSTEM

Design and develop a lightweight and robust tank health monitoring system capable of working in harsh environment of the tank over its lifecycle and automated inspection system

Objective 6

STORAGE SYSTEM INTEGRATION AND TESTING

Integrate and demonstrate the entire LH2 tank system

Objective 7

TANK SAFETY AND LIFE CYCLE EVALUATION

Understand life cycle and safety impact of tank design decisions and develop a suitable inspection method

Key Performance Indicators (KPIs)

The targeted KPIs are as follows:

 

Dormancy: >24h

Boil-off: <2% per day

Gravimetric Index: 25%

General approach

The COCOLIH2T activities are broken down into nine Work Packages (WPs).

WP2 and 8 are horizontal WPs that are meant to inform and provide inputs/support throughout the project to WP3, 4, 5 and 6. Additionally, WP3 focuses on the concept definition and design of the disruptive LH2 tank. Its outcomes will be key for the subsequent design and development of key systems performed within WP4, 5 and 6. All the outcomes generated within WP2-8 will flow into the final system integration and demonstration (WP7). Finally, WP1 and WP9 will ensure a proper project management, communication, dissemination and exploitation.

External Expert Advisory Board (EEAB)

COCOLIH2T will set up an External Expert Advisory Board (EEAB) to provide the consortium with additional external guidance and feedback along the project execution in an effort to maximize the project outcomes, while minimizing the risks. The EEAB will involve key stakeholders in the decision chain as early as possible. This will comprise of diverse industry members that will be announced in the coming months. Meetings will be organized at least yearly with the EEAB to assess technical progress, results, and compliance with requirements.
