Hydrogen

Removing the technical barriers to use of hydrogen in natural gas networks and for (natural) gas end users.

Hydrogen has now become a major pillar of the European roadmap to carbon neutrality. Opportunities exist to blend hydrogen into the existing natural gas network, and also to repurpose the network for dedicated hydrogen use. Technical barriers remain, and these are perceived differently across European transmission and distribution network. Additionally, a full impact assessment on the wide range of end users (domestic, commercial and industrial appliances, mobility, power generation, etc) still needs further work. In particular these all need to be addressed to develop the European standards that are necessary for the implementation of hydrogen across Europe.

Therefore, the European Commission has funded, via CEN a project aiming at “Removing the technical barriers to use of hydrogen in natural gas networks and for (natural) gas end users". GERG are delivering this project on behalf of CEN and a new Working Group has been created in CEN/TC234 to oversee the work.

The objective of this project is to review the current scientific and technical framework concerning the use of hydrogen, and drawing from this review a gap analysis which can then be translated into a set of pre-normative research (PNR) requirements. This work will then contribute to the process of standardisation for the introduction of hydrogen into the gas networks and for end users.

The project is divided into 8 priorities being delivered in parallel

  1. Safety
  2. Gas Quality
  3. Underground Storage
  4. Power generation and engines
  5. Industry
  6. Steel pipes
  7. Network Equipment
  8. End use appliances

Each WP will gather and assess the status of knowledge by collating and reviewing project reports, papers, internal documents etc. This process is generating a huge database: currently more than 800 references. From this knowledge survey and assessment, a gap-analysis will be constructed to identify areas where knowledge is sufficient and where there are gaps for specific H2 concentrations. Ultimately the project will develop plans for PNR activities focusing on lowering barriers to standardization. A final consolidated report will be published at the end of the project.

The project will run until November 2021, and will receive funding of up to €1.1M from the European Commission via CEN (specific agreement N° CEN/2019/ENER/C2/452-2019/SI2.831737)

THyGA: Testing Hydrogen admixture for Gas Applications

The project THyGA (Testing Hydrogen Admixtures for Gas Appliances) has launched the 28th of January 2020, with a first meeting at the GERG office in Brussels. Funded by the FCH JU work programme, THyGA sets out to develop and communicate a detailed understanding of the impact of blends of natural gas and hydrogen on end use applications, specifically in the domestic and commercial sector.

The project is being coordinated by Engie. Eight other partners from six European countries (DGC, Electrolux, BDR, Gas.be, CEA, GWI, DVGW-EBI and GERG) will work together on this project over 36 months. The consortium includes laboratories, gas value chain companies, manufacturers representing different applications (cooking, heating), and an international association. It will be supplemented by an advisory panel of manufacturers and gas companies which will be closely integrated with the main project team.

HIPS-NET - The hydrogen network

This network keeps its members updated on new developments and activities in the world of hydrogen and its use in natural gas systems. For an annual fee of €2000 members receive a quarterly newsletter and invitations to an annual workshop. The network is open to new members.  

Contact the GERG Secretariat for all questions relating to membership.
For other information, please visit the project website or read the report of the HIPS Project listed below.  

This project directly follows the highly successful HIPS Project, the report can be found below. 

Hyready

The HYREADY project provides gas systems operators – TSOs and DSOs – with engineering guidelines so their networks are ready to accept hydrogen-natural gas mixtures.  

The guidelines help systems operators calculate the acceptable percentage of hydrogen that can be added to a gas network, and provides descriptions of measures to take in case an upgrade of the network is necessary. 

The project consists of 11 project partners led jointly by Norwegian technical consultancy DNV GL, and German gas company DBI-GUT.  

Additional details can be found in the report listed below.  

Sector Forum Energy Management, Working Group Hydrogen

GERG joined experts from throughout Europe in this working group on hydrogen led by the European Commission’s Joint Research Centre (JRC) and the European Committee for Standardization  (CEN).

The aim was to bring the scientific knowhow on hydrogen energy systems, gathered by GERG and others, together in a roadmap for standardisation.   

The scope of the working group covered the production of hydrogen through electrolysis as well as its transportation, distribution and use in pure form or as a natural gas dominant mixture (H2NG).  

Key outcomes can be found in Part 1 of the report (see below). The report also includes: Priority challenges identified for the various technical areas; recommendations on proposed actions with means of implementation; and visual representation of these actions in an action roadmap.   

Elegancy

This project fast-tracks the decarbonisation of Europe's energy system by exploiting the synergies between two key, low-carbon technologies: carbon capture and storage (CCS) and hydrogen (H2).  

Elegancy is part of the European Commission’s ACT (Accelerating CCS Technologies) programme and is led by the independent research organisation Sintef.  GERG is a full member and a member of the Executive Board.  

The Elegancy research programme comprises six work packages:  

  • Hydrogen supply chain and hydrogen-carbon dioxide (H2-CO2) separation  
  • CO2 transportation, injection and storage  
  • Business case development for H2-CCS integrated chains  
  • H2-CCS chain tool and evaluation methodologies for integrated chains  
  • Five case studies, one per participating country 
  • Project management, network building and dissemination  

This project ends in August 2020. For more information, please visit the project website below.
