Hydrogen safety

Safety is one of the most important aspects in the hydrogen economy both in the Netherlands and worldwide; therefore, we dedicate a significant part of the HyDelta research programme towards answering some of the most urgent and important questions about safety of hydrogen transport, that include questions both related to hydrogen in the built environment as well as questions independent of the mode of transport. We have four WPs dedicated to this topic namely,

  1. WP1A: Hydrogen distribution and safety - carrying out a Quantitative Risk Assessment of hydrogen in the built environment
  2. WP1E: Impact of high velocity of hydrogen flows - simulation of potential effects of high-velocity hydrogen in the transmission and distribution networks
  3. WP2: Odorisation of hydrogen - in search for the best odorant for hydrogen
  4. WP3: Standards and regulations - investigating the status of the development of standdards and regulations around hydrogen in the Netherlands

Hydrogen in the gas grid

Hydrogen in the gas grid refers to the work packages in the HyDelta program carrying out specific questions about the operation, maintenance, and component selection for the transport of hydrogen in the existing gas transmission and distribution infrastructure. This work has been placed in the context of the existing standards and operating procedures of the Dutch gas transport system operators, but the results can be applicable to other gas transport systems in the world. We have five WPs dedicated to this topic namely,

  1. WP1B: Gas stations - safe working procedures around hydrogen in gas stations
  2. WP1C: Pipes and indoor installations - safe working procedures and piping component selection
  3. WP1D: Metering of hydrogen - evaluating potential gas metering options for hydrogen in households
  4. WP1F: Shut-off valves in the Dutch gas transmission grid - testing of installed shut-off valves in the gas transmission grid for suitability with hydrogen
  5. WP4: Educational tracks - quantification and development of educational tracks for future technicians working in a hydrogen transmission and distribution system in the Netherlands

Value chain & Hydrogen admixing

Besides the technical requirements for the transport of hydrogen in the existing gas transport infrastructure, the financial case needs to be proven. Furthermore, the inclusion of hydrogen as an extra fuel in the existing fuel trading and consumption systems i.e., the trading of certificates, the standards for admixing and the availability of subsidies and other policy instruments, will have consequences that we need to investigate before being able to provide a full picture of the potential of hydrogen as a booster to our economy. The value chain and hydrogen admixing work packages aim at investigating the state of the art of the hydrogen technologies, the potential business cases that exist aroud them, and an investigation into the topic of hydrogen admixing from a policy perspective. We have four WPs dedicated to this topic namely,

  1. WP7A: Techno-economic value chain analysis - analyzing the levelized cost of hydrogen (LCOH) of different value chains
  2. WP7B: Technical analysis of H2 supply chains - mapping of the state of the art for hydrogen technologies and a subsequent roadmap for the ongoing technology development
  3. WP7C: System value of green hydrogen - discerning the potential benefits of green hydrogen in the Dutch economy
  4. WP8: Admixing & mandatory blending - evaluating the existing Dutch policies regarding mandatory blending and certificates trading towards the creation of a hydrogen mandatory blendinbg and certificates trading system
