Enapter AG has unveiled the AEM Multicore – the world’s first megawatt-class AEM electrolyser for the production of green hydrogen, ushering in a new era in environmentally friendly solutions for the decarbonisation of industry and the economy, and reaching an important milestone in its corporate history.
HyET Hydrogen and ENPRO Industries have signed an MoU, under which ENPRO will function as an engineering and manufacturing partner for electrochemical hydrogen processing equipment. Additionally, ENPRO will set-up and oversee the manufacture and assembly of HyET’s equipment.
Johnson Matthey (JM) and Hystar have signed a three-year strategic supply agreement to ramp up green hydrogen production. JM will supply membrane electrode assemblies (MEAs), key performance-defining components for electrolysers, as part of Hystar’s commercialisation ramp-up.
thyssenkrupp nucera and H2 Green Steel have entered into a supply agreement that secures capacity of more than 700 MW for H2 Green Steel’s electrolysis plant in Boden, Sweden. The agreement covers alkaline water electrolysis technology and large-scale electrolysis plant engineering.
As hydrogen becomes more prominent in the portfolio of technologies for reducing carbon emissions, more attention has been directed towards its safe transport, storage, and end use. Most hazard scenarios involve the unintended release of hydrogen, which can result from improper design, assembly, or operation of hydrogen containment systems. One important aspect of design is the selection of materials, particularly those comprising the pressure boundaries of hydrogen containment components. From the perspective of unintended hydrogen release, materials selection is focused on two particular concerns related to hydrogen ingress: 1) hydrogen permeation rates in materials, which dictate the leak rates through pressure boundaries, and 2) the potential for hydrogen to degrade the mechanical properties of materials, which can lead to failure of pressure boundaries and sudden release of hydrogen. This article focuses on the second concern, and more specifically on the hydrogen-induced degradation of metals. In gaseous hydrogen environments at near-ambient temperatures, failure resulting from hydrogen-induced degradation of metals is typically referred to as ‘hydrogen embrittlement’.
Storage and transportation of hydrogen in liquid state offers several advantages. Liquid hydrogen (LH₂) has a higher density and requires a lower storage pressure compared to gaseous hydrogen. However, hydrogen turns into liquid at -253°C, which brings its own challenges. The very low temperature as well as the risk of flammability make it a challenging medium. Stringent safety measures and reliability are thus a must when designing valves for this application.
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).
