Hydrogen Europe – Different Energy Carriers Require Separate Systems of Guarantees of Origin

Published July 2021 by Hydrogen Europe

Key Recommendations

1. Create a distinct hydrogen GO, separate from electricity and gas.

2. Encourage the use of GOs in addition to PPAs to prove the renewable character and CO2 intensity of the electricity procured for the production of renewable hydrogen.

3. Initiate the development of a global system for Hydrogen Guarantees of Origin (HGOs), with track-and-trace and auditing functionality.

4. Set clear ground rules that avoid false or misleading claims. Enable the cancellation of H2 GOs, and the issuance of a natural gas GO when physical volumes are blended.

Hydrogen has seen unprecedented momentum and is fast becoming a systemic element in the EU’s transition towards a climate-neutral society in 2050. It will become the other leg of the energy transition – alongside renewable electricity – by replacing unabated fossil fuels and ensuring greater systemic synergies. Clean hydrogen[1] is not the backdoor to the continued use of unabated fossil fuels, nor is it the trojan horse of the natural gas industry greenwashing its way towards competitive markets.

Hydrogen Europe – Unlocking the Potential for Clean Mobility: the revision of CO2 emission standards for cars & vans

Published July 2021 by Hydrogen Europe 

Executive Summary

Hydrogen Europe considers the revision of the Regulation setting CO₂ emission performance standards for new passenger cars and new light commercial vehicles[1] to be a key legislative initiative to help the EU deliver upon its 2030 climate targets and to reinforce its global leadership in zero-emission vehicles, particularly hydrogen fuel cell vehicles.

Consequently, we call on the EU institutions to maintain the level of 2025 targets while strengthening the 2030 targets, provided the enabling framework conditions are in place, and a holistic approach is taken. As the Regulation covers different vehicle types, these differences should be reflected when it comes to targets, with dedicated sets for each vehicle category; in this respect, the key role of fuel cell electric vehicles for both segments should be acknowledged.

Low carbon and renewable fuels have a central role to play, and this should be considered in the text by including a provision giving an option for manufacturers to take part in a voluntary crediting mechanism for renewable fuels of non-biological origin, which would be linked to an obligation to invest into zero-emission vehicles.
Another key element of the proposal should target the overall system and resource efficiency: its role should be carefully analysed and recognised in the proposal. The uptake of low and zero-emission vehicles will be severely hampered if not supported by an efficient system.

Lastly, Hydrogen Europe calls for the allocation of emission premiums to upskilling, reskilling and hydrogen refuelling station deployment. In addition, Europe needs technicians and automotive personnel to have all necessary skills and competencies to work on hydrogen vehicles since they have fundamental differences from internal combustion engine vehicles.

Hydrogen Europe, ENTSOG, GIE – How to Transport & Store Hydrogen – Facts & Figures

Published in May 2021

ENTSOG, GIE and Hydrogen Europe have joined forces on a paper that answers a number of fundamental questions about gaseous and liquid hydrogen transport and storage. This paper provides an objective and informative analysis on key concepts, terminology and facts and figures from different public sources.


There are three pathways for the integration of hydrogen into the gas system: the injection of hydrogen and its blending with natural gas in the existing gas infrastructure, the development of a dedicated hydrogen network through conversion of the existing gas infrastructure or via the construction of new hydrogen infrastructure and finally via methanation, consisting in capturing CO2, combined with hydrogen in order to produce e-methane, injected in the gas network. Those models are complementary and depend on the production technology, the concerned zone or even the temporality of the projects. Today the gas infrastructure can accommodate any form of low carbon hydrogen, independently from the technology used for its production, such as electrolysis, gasification of biomass, steam methane reforming combined with capture of CO2 or steam methane reforming of biomethane, electrolysis of molten salt.


Hydrogen blending is the injection in the existing gas infrastructure of a share of hydrogen into the overall volume of gaseous energy carriers. With exceptions related to injected shares and areas of application, the respective hydrogen blending levels may not substantially affect the capacity of the gas infrastructure [1].


Hydrogen deblending is the reverse process of hydrogen blending and allows to extract pure hydrogen for dedicated uses (e.g. hydrogen fuel cells, feedstock) as well as reasonably hydrogen-free natural gas. For hydrogen deblending, different designs of membrane plants and combinations with other technologies are used (e. g. polymer membrane, carbon membrane, metal membranes, glass/ceramic membranes, membrane-PSA) to separate hydrogen from gaseous energy carriers. There are several important factors to be considered when choosing the most suitable technology, such as permeability, selectivity, stability of the membrane material, effects of discontinuous operation on the operation, design of the membrane plant, effects of different hydrogen concentration on the separation process. Hydrogen separation effectiveness depends on the hydrogen concentration in methane. It is also important to ensure proper management of the separated hydrogen. However, the technology is currently under development and additional R&D analysis is needed.


The maximum allowable hydrogen concentration depends mainly on pressure fluctuations, structure and existing defects. However, widespread knowledge to date indicates that, for some grid sections, certain blending percentages (e.g. 2%–10% in volumetric terms) are technically feasible with few adaptations in some Member States. Although additional tests are needed some operators consider 20% the upper bound due in particular to the requirements for downstream users to be adapted beyond this point2 (Figure 1). As regards to technical regulation, blending of hydrogen is explicitly recognized by a few Member States.
