Powering the future with green hydrogen

The article covers hydrogen storage, transport and vehicle fuelling, drawing mainly on comments from Hexagon Purus and Nel. Hexagon Purus says its Type 4 composite cylinders are up to 75% lighter than steel cylinders, improving transport payload and reducing the number of trips required. The article describes planned pressure increases from 300 to 380 bar and development of 500 bar cylinders. It also relays the company’s claims about cylinder durability and maintenance economics.

The article says hydrogen safety protocols, connectors and standards have been developed and harmonized internationally, while noting hydrogen’s small molecules can make leak prevention more difficult. It describes Nel’s hydrogen fuelling stations and compressor technology, and cites a manufacturing plant designed for 300 stations per year; this capacity figure and all rollout numbers reflect the article’s dated reporting and should not be treated as current market data.

It discusses the “chicken and egg” problem in hydrogen mobility: low vehicle availability limits station demand, while sparse refuelling infrastructure limits vehicle adoption. Hexagon Purus’ 2020 framework agreement with Everfuel is cited for transporting hydrogen between production sites and fuelling stations in Denmark, the Netherlands and Norway. The company representatives argue that hydrogen may suit heavy-duty vehicles where battery weight, payload and charging time are constraints. The article also contains comparative claims about hydrogen versus battery vehicles, attributed to those representatives.

Companies discussed: Hexagon Purus (storage and transport cylinders); Nel (electrolysers and hydrogen fuelling equipment); Everfuel (distribution agreement). Related links: Transportation; Energy; Hydrogen.
