One European operation for your hydrogen, LNG and CNG equipment.
Start a scoping conversationWhy NEXOS
NEXOS is Latin nexus: a bond, a tie. We are the European pillar of an Asian manufacturer’s operation.
Most certification bureaus stop at the certificate. NEXOS begins there, and carries the years that follow: the European point of contact, the authority liaison, the monthly watch on the directives that touch your equipment, as one engagement.

Common questions
What NEXOS is, and is not.
What does NEXOS do that a notified body does not?
A notified body issues the certificate. NEXOS carries the years after it: the European point of contact, the customer and authority liaison, and the monthly watch on the directives that affect your equipment.
Is NEXOS a consultant?
No. Our experience is operator-side, eight years inside European hydrogen, LNG and CNG infrastructure, where the requirements actually land, not advice from a consultancy desk.
Do you sell or install equipment?
No. NEXOS is not a distributor, reseller or agent, takes no commission on your sales, holds no formal Authorised Representative role, and does no installation or field work. We represent no competing manufacturers.
What does an engagement look like?
One engagement: the sustained European representation of your operation. A twelve-month minimum, typically multi-year, delivered on IPMA-D project management with a structured Operations Letter on the second working day of every month.
Which equipment and directives do you cover?
Hydrogen, LNG and CNG fuelling equipment under CE, PED, ATEX and adjacent European directives, including ADR for transport and the Dutch PGS series.
How do we start?
With a scoping conversation. It is where both sides establish whether there is a fit, before any engagement begins.
