About

A Swedish branch of SEngineers GmbH.

Zephirion Engineering Filial Sverige is the Swedish branch of SEngineers GmbH, Switzerland, working from Karlskrona, Blekinge, Sweden.

The branch

Small on purpose, and specific about it.

Zephirion Engineering works with advanced systems engineering and integration. The work sits at system level: taking components that already exist and making them behave as one system inside the limits of the platform they have to work in.

A small branch has one real advantage, and we would rather state it than dress it up. There is no account layer between you and the engineer doing the work. The person who answers the phone is the person who will read your requirements.

Zephirion is the name of the group’s hydrogen-electric aviation work, and SEngineers GmbH is the engineering company behind it. The Swedish branch carries both: the aviation project, and the same systems engineering applied to industrial work.

Principal engineer

Martin Seng

Principal Systems Engineer

A graduate electrical engineer with more than 30 years of professional experience, who has grown into a systems engineer with a strong focus on embedded systems and power electronics. His earlier work includes fuel-cell system development at Nucellsys for the Daimler A-Class and B-Class, as project manager and electrical engineer. He is a licensed pilot, and is developing fuel-cell electric propulsion for general aviation and industrial use.

Enquiries, technical questions and programme discussions all go to him directly. No form, no queue, no account manager.

Engineering view

We would rather say what is difficult than what is impressive.

Hydrogen-electric propulsion is not held back by any single component. It is held back by the arrangement: budgets, thermal paths, two dissimilar sources on one bus, and the evidence needed before any of it is trusted in the air.

That is an unglamorous position, and it is the honest one. It is also the reason our work is described here in general terms rather than as a list of achievements.
