In an exclusive interview with Hydrogen Tech World, Willem Frens, a seasoned business, project, and technology developer, shares his extensive knowledge and experience in green hydrogen and sustainable energy and process technologies. Mr. Frens discusses optimal locations for green hydrogen production, the importance of local offtake and export strategies, and advancements in electrolysis technologies. His insights provide a roadmap for the future of hydrogen production and the global energy transition.

Stiesdal Hydrogen, a subsidiary of the Stiesdal climate technology group, is paving the way for genuine industrialization of green hydrogen production. Founded in 2020, the Danish company has delivered the first three units of its 3.1-MW HydroGen Electrolyzer, offering not only a completely new approach to the overall electrolyzer arrangement but also a new take on alkaline technology that enhances flexibility and applicability. Hydrogen Tech World spoke with Esben Baltzer Nielsen, Head of Sales & Business Development at Stiesdal Hydrogen, to explore the company’s advancements.

We live on the Blue Planet, but even here freshwater is a scarce resource. Only2 % of all water in the world is freshwater, most of which is either locked away in glaciers at the poles or stored deep underground. This means that only a tiny fraction, 0.3% of the freshwater, is found in rivers and lakes. For water-intensive industries looking for sustainable water use, the dream is therefore to tap into the ocean and utilize the vast amount of seawater. In this article, the use of seawater for green hydrogen production is examined with a focus on the initial desalination step in the process towards ultrapure water. Key considerations and technical aspects are explored by answering essential questions like: Is seawater a viable source of water for green hydrogen? What are the water treatment issues when using seawater for green hydrogen? And should you opt for membrane-based reverse osmosis or thermal evaporation?

Iron Power represents a groundbreaking approach to energy production. By harnessing the power of iron as a fuel source, we are pioneering a sustainable alternative to traditional energy sources. This innovative technology not only promises to offer CO₂-free energy, but also offers a reliable and efficient solution to meet the world’s growing energy needs.
