Workshop: Identify and deal with specificities of P2H2 as enabler of transition:
performance-based standards for smarter regulation What? Who? By When, How?

Captive RE
H2 storage
• Clear definition of electrolyser system with standardised KPIs
• Electrolysis mature technology, but adaptation to flexible operation needed
• Revision of electrolyser standard
• Electrolyser safety
• Alignment of policy, technology and standards framework
Session 1 – Next Steps (1)
• R&D to adapt and improve the technologies
• Demonstration projects to prove the potential of the technologies in the field, driven by industry in collaboration with research.
• Improve the understanding of national/EU legislations, scenarios and business cases for electrolysis and energy storage.
• Involve other stakeholders, namely grids operators, end users, etc.
• Develop and update the regulatory framework.
Session 1 – Next Steps (2)
Market creation/regulatory
framework
Research and Development
Defining H2 as green fuel
Integration of technologies in
electricity, gas and heat grids
Interface with different
applications/uses:
o mobility,
o energy and
o industry
Definition of boundary conditions
Definition of key parameters
(lifetime, durability, service, quality,
safety and security)
Storage control
LCA and LCC
Materials
Use of pipelines (beyond NaturalHy)
Underground storage
Major role of demonstration driven by industry for specifying boundary
conditions and for assessing technical feasibility
Major role of research organisations for defining and proposing relevant
R&D approaches on energy systems, on electrolysis technologies, on single
components and for achieving innovations
Iterations between demonstration and R&D required for bridging the gap
between demonstrated technical feasibility and the availability of
solutions for storing intermittent energy being economically and
environmentally relevant, liable to be introduced on the market and
submitted to societal acceptance

Main Issues - Session 2
• Establishing a European understanding of H2 tolerances
• Necessity of regulatory support
• Integrated approach necessary
• Fluctuating gas composition
• Further research: CNG tanks and filling stations, appliances and industrial burners, underground storage, compressors, gas composition analysis
Session 2 – Next Steps
• Establish the limit of H2 that can be safely injected in the natural gas grid
• Develop meters/methods for H2 concentration monitoring
• Material research in order to better understand H2 tolerance on pipelines, storage tanks etc.
• Consolidate knowledge of existing projects and identify gaps where more research is needed
• Macroeconomic evaluation of power to gas routes including the cost for adaption.
Main Issues - Session 3
• The injection of H2 in the natural gas grid will affect all the current gas users
• Compensation systems for gas quality fluctuations
• End user installations certification for HCNG
• H2 limits set in future may not exceed 20% for safety reasons?
• Public acceptance
Session 3

Low-carbon Heating
HCNG
Mobility
Session 3 – Next Steps (1)
Pre-normative research:
• flame length, temperature and heat radiation.
• end user installations certification for HCNG regarding their compatibility with flame stability and hydrogen embrittlement.
• ATEX zoning needs to be reassessed.
• Detection devices and mitigating safety measures need also to be certified.
•
• Need for a compromise on wide composition range for natural gas (to support security of supply) but equipment manufacturers need a narrow composition range to develop appliances.
• Vehicle tanks to accept higher H2 concentrations.
• Regulatory framework not adapted for HCNG.

Standardization Activities
Main Issues - Session 4
• Wind curtailment increasing
• Grid balancing services support RES
integration increasing need for
ancillary services
• Fast response electrolysis opportunity
for frequency control
• Voltage control other potential service
• Positive effect on the business case

Captive RE
Renewable Power
Session 4 – Next Steps
• limited experience with using electrolyser as ancillary service provider widening of service codes?
• TSO/DSO crucial part in grid service discussion
• Technical needs as an input to standardization:
• definition of test, measurement methods and load cycles in electrolyser performance standards to enable qualification for ancillary service provision (as well as conformity assessment by operators)
• definition of quality related parameters to determine/value the quality of supply of ancillary services

What we did not hear about
• Resource efficiency aspect: water?! • Energy security: impact of reverse gas flows?
General observations • Puzzle: multi-piece, multi-player, multi-dimension • We need common terminology • Efficiency has to be assessed at system level, not only of
individual conversion devices • Renewable hydrogen is the key word • YES, costs and cost evolution are important
