Technology selected for green hydrogen projects

Nel ASA says that it has entered into an agreement with GreenH to be the technology provider for the Enova-supported projects in Kristiansund and Slagentangen. GreenH develops, builds, owns, and operates hydrogen production facilities based on renewable energy. The company aims to establish a network of distributed hydrogen production sites to enable decarbonisation in the maritime, transport, and industrial sectors. GreenH focuses on scalable solutions located close to end users, reducing logistics costs and supporting the development of efficient, regional hydrogen value chains. The facilities in Kristiansund and Slagentangen are intended to supply green hydrogen to industrial and maritime users and form part of GreenH’s broader efforts to establish a network of distributed hydrogen production in Norway.

Greene Tweed achieves hydrogen compression breakthrough

Greene Tweed, a leader in advanced materials and high-performance solutions, says it has achieved a significant advancement in hydrogen compression technology. The company’s newly engineered composite closed impeller set a record-breaking tip speed of 688 m/s in testing – nearly double that of traditional metallic impellers. The innovation highlights the potential of advanced composite materials to enhance performance, reduce costs, and improve efficiency in critical hydrogen pipeline infrastructure, specifically the transportation, storage and utilisation market segments.

MHI successfully produces hydrogen at ammonia cracking pilot plant

Mitsubishi Heavy Industries says that it has succeeded in producing 99% pure hydrogen by cracking ammonia using steam as the heating source. The production of hydrogen at pilot scale using the steam heating was conducted at the company’s pilot plant in the Nagasaki District Research & Innovation Centre, marking a world first. By contrast to technologies that use heat from burner combustion, MHI’s steam heating system operates at lower reaction temperatures, reducing operating costs. In addition, because a combustion furnace is not required, the system offers excellent features such as the potential for miniaturisation.
