The cylinder plays a crucial role in the application of gaseous hydrogen. It is indispensable, regardless of whether it is used for stationary applications, mobile storage during transportation, or at the vehicle level. The search for a product that offers sufficient storage capacity and is constructed in a way that ensures safe handling of hydrogen is an ongoing process.

Water electrolysis (WE) is key to decarbonising hard-to-abate industries such as fertilizers and steel. Four main technologies – alkaline (AWE), proton exchange membrane (PEM), solid oxide electrolysis cells (SOEC), and anion exchange membrane (AEM) – can be found in the market, each with its own advantages and disadvantages. This article provides a short review of these technologies and analyses their impact on the levelized cost of hydrogen (LCOH).

Established in 1889, PRUSS is a globally trusted supplier of control valves and actuators for various industrial sectors. Recognising the role of hydrogen in the future energy landscape and leveraging decades of expertise in flow-control solutions for hydrogen service, PRUSS now provides an extensive range of valve products for large-scale systems used in water electrolysis, hydrogen transport, storage, and industrial applications. To learn about the company’s latest projects and developments, we talked to Wilfried Drehmel, CEO of PRUSS.

The inaugural Hydrogen Tech World Expo & Conference is around the corner! Bringing together hydrogen experts from around the globe, this two-day event provides an excellent opportunity to meet with leading equipment and component manufacturers, system developers and service providers from across the hydrogen value chain, as well as to learn from and talk to engineers, system integrators, technology innovators and end users. Join us in Essen on 4 and 5 April!

With more than 25 years of experience in PEM electrolysis and – as a daughter company of MAN Energy Solutions – operating under the umbrella of the German giant Volkswagen, H-TEC SYSTEMS has all it takes to realise its strategic objective to become one of the top three players in the global PEM electrolyser market. As the company prepares to go large scale, we talked to Jonas Wahl, Director of Product Management, to learn more about the company’s current projects and vision for the future.

Two major challenges are hiding behind the investments in green energy production. They arise from the fact that (variable) renewables are often produced at the wrong time and place. Therefore, the development of both storage and transportation capacity is crucial. Sweco shares lessons learned from the first large-scale project developments with VoltH2.

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.

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.
