PtX (Power-to-X) covers several different technologies, each with its own technical requirements. At LR Marine, we focus on the PtX applications where pipe system design, safety and operational reliability are critical – and where we have practical experience from real projects.
Our involvement in PtX projects is based on pipe systems for hydrogen, methanol, ammonia and green gas solutions, as well as large-scale cooling water systems used in PtX plants. These applications place high demands on materials, safety concepts and long-term performance.
Hydrogen is a central element in many PtX projects, but it is also one of the most technically demanding media to handle. Due to its small molecular size, hydrogen can penetrate materials over time and may lead to hydrogen embrittlement in piping materials.
For hydrogen applications, LR Marine supplies double-wall stainless steel pipe systems designed to meet safety requirements for media with low flash points. These systems are used both in industrial PtX facilities on land and in marine environments where safety and controlled handling are essential.
While hydrogen technology continues to develop, our role is clear: when a hydrogen system is ready for execution, we deliver pipe solutions based on proven materials, documented designs and practical installation experience.
In several PtX projects, hydrogen is combined with captured CO₂ to produce methanol. Methanol is easier to store and transport than hydrogen and is increasingly used as a marine fuel and energy carrier.
LR Marine delivers pipe systems suitable for methanol applications, typically requiring double-wall solutions depending on installation area and safety regulations. Our focus is on reliable handling of methanol in systems designed for continuous operation and long service life.
Another PtX pathway involves combining hydrogen with nitrogen to produce ammonia. Ammonia offers a relatively high energy density and is gaining attention as a future fuel, particularly in the maritime sector.
Pipe systems for ammonia require the same high level of attention to safety as hydrogen and methanol systems. LR Marine supplies pipe solutions designed to meet these requirements, including double-wall pipe systems where required by regulations or project specifications.
Some PtX projects focus on upgrading biogas to green gas or LNG for use as fuel. These installations involve handling of gas under controlled conditions and often require a combination of safety-focused pipe systems and insulation.
LR Marine supplies pipe systems for gas-related applications where reliability, documentation and compliance with applicable standards are essential.
Regardless of the PtX pathway, cooling plays a major role. Electrolyzes, compressors and conversion processes generate significant amounts of heat, and stable operation depends on reliable cooling systems.
LR Marine supplies pre-insulated UV-protected pipe systems for cooling water and glycol circuits in PtX plants. These systems are designed for outdoor and exposed installations, minimize heat loss and prevent moisture ingress into the insulation. In several projects, the cooling systems are integrated with district heating networks to utilize surplus heat from the PtX process.
LR Marine has delivered pipe systems to PtX related projects in Denmark, including large-scale facilities with high demands on cooling capacity and operational reliability. Our involvement typically includes technical input during the design phase, fabrication of tailor-made pipe systems and on-site supervision during installation.
This practical experience allows us to support PtX projects with pipe solutions that work in practice – not only on paper.
PtX technologies are still evolving, but the requirements for pipe systems remain consistent: safety, reliability and long service life. At LR Marine, we focus on the PtX applications where these requirements are well defined and where our experience adds real value.
When PtX projects move from concept to execution, we deliver pipe systems designed to operate reliably throughout the lifetime of the installation.
