Researchers from the University of Adelaide have successfully split seawater without pretreatment to produce green hydrogen. The team will now work on scaling up the system by using a larger electrolyser, so that it can be used in commercial processes such as hydrogen generation and ammonia synthesis.
Linde has announced plans to increase its green hydrogen production capacity in Ontario, California, in response to growing demand from the mobility market. The company will build, own and operate the first of several planned 5 MW PEM electrolyzers to increase its hydrogen capacity.
Plug Power and Johnson Matthey (JM) have announced a long-term strategic partnership to accelerate the green hydrogen economy. JM will become an important strategic supplier of MEA components, providing a substantial portion of Plug’s demand for catalysts, membranes, and catalyst coated membranes (CCM).
Implementation of the Swedish ‘Project Air’ is moving full steam ahead. Uniper has commissioned Dresden-based Sunfire to build a 30 MW pressurized alkaline electrolysis plant, which will generate green hydrogen using renewable electricity and purified wastewater. The final investment decision is still pending.
Hydrogen vent systems play an essential role in ensuring hydrogen safety. For many applications, it is common practice to connect all normal hydrogen piping vent points, including relief valves, to a vent system. Evaluating this system during the facility hazard review is essential. This evaluation is often missed, and there have been numerous incidents in which improper vent stack design or operation caused injuries and property damage. This article addresses critical safety issues in vent system design and operation for liquefied (LH2) and gaseous (GH2) hydrogen.
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.
Among the recent entrants to the rapidly expanding universe of electrolyser manufacturers, Hystar is shining particularly brightly. Combining knowledge from the fuel cell industry with electrolyser technology, the Norwegian company claims to have developed the world’s most efficient PEM electrolyser. With market-ready solutions, Hystar is now gearing up to fully automate its production process and ramp up production capacity to gigawatt scale.
