Electrolyser safety through certification

Electrolysers range from small, appliance-size products to large, multi-megawatt-scale production facilities. In all cases quality and safety must be ensured. One of the major concerns when designing, building, operating or even talking about a hydrogen system is safety. Known for its high flammability range and small molecular size, hydrogen can easily leak, forming an explosive mixture if adequate measures are not taken. Taking adequate measures, however, can be a straightforward process if attention is paid to safety from the design on.

Platinum group metals: an enabler for hydrogen, not a barrier

Proton exchange membrane (PEM) electrolysers and PEM fuel cells rely on platinum group metal (PGM) catalysts, notably platinum and iridium. Many see this as a challenge, given the rarity and value of the PGMs. In fact, if used efficiently, these metals will actually facilitate the development of a resilient supply chain. To understand why this is, let’s look at the PGM landscape and the implications for PEM technologies in more detail.

Green hydrogen: meeting future sustainability requirements

Hydrogen is a key element for the decarbonisation of industry, if low-emission production and logistics follow. However, so far there has been a deplorable lack of binding EU-wide sustainability criteria that cover the entire value chain. A certification assists companies to establish a position in the emerging market for hydrogen from renewables and to prepare for future requirements.

Clean hydrogen has an iridium problem

Proton exchange membrane (PEM) electrolyzers can produce hydrogen from water and renewable electricity. They also typically rely on one of the rarest materials on earth to function: iridium. To scale this technology to meet rising demand for clean energy, the hydrogen community must develop solutions to address this scarcity problem.

When pipelines transport hydrogen instead of natural gas

Hydrogen plays a central role in the energy transition, and existing natural gas infrastructure is to be used for its transport and storage. TÜV SÜD assesses the integrity and service life of the pipelines intended for this purpose using fracture mechanics calculations. In doing so, the experts take into account the embrittlement of steel and factors such as crack initiation and crack growth under hydrogen atmospheres
