MOLARIS
Engineering for the hydrogen energy transition
We design and evaluate green hydrogen and renewable gas infrastructure with the same rigor an engineer holds for anything they put their name on: from conceptual engineering to executable detail, with ATEX, HAZOP and SIL safety built in from the first sketch.
Project engineering: from concept to operating plant
We support every stage of green hydrogen engineering with the level of definition that stage requires — no gaps, no redesign cost overruns. Each deliverable is the solid foundation for the next.
Conceptual engineering
We define the architecture of the hydrogen project: mass and energy balance, electrolysis technology selection, and early CAPEX/OPEX estimates to validate technical feasibility before committing investment.
FEED (Front-End Engineering Design)
FEED engineering for hydrogen plants: process diagrams (PFD/P&ID), main equipment sizing and technical specifications with the precision a Final Investment Decision (FID) demands.
Basic engineering
We develop basic engineering for the hydrogen plant: layout, utility balance, critical equipment specification and design basis for the EPC contracting phase.
Detailed engineering
Construction-ready detailed engineering — mechanical, electrical, instrumentation and civil works — with the level of definition a real hydrogen plant build requires.
Owner's Engineering and Technical Due Diligence
When an EPC contractor or third party executes the project, your investment needs its own technical criterion defending it. We act as the Owner's Engineer, not the contractor's.
Owner's Engineering
Independent technical oversight on the owner's behalf during design and construction: reviewing the EPC's engineering, controlling deviations and defending the investor's technical interests against the contractor.
Technical Due Diligence
Technical audits of hydrogen projects for investment, acquisition or financing processes: we verify the design, production assumptions and technical risks before you sign.
Commissioning and start-up
Commissioning engineering and start-up support for the hydrogen plant, verifying that what's built matches what's designed before commercial operation.
Hydrogen plant design
End-to-end engineering of renewable hydrogen production, storage and distribution plants, sized to the project's real demand and ready for integration into the existing energy grid.
Industrial safety: ATEX, HAZOP and SIL
Hydrogen demands a level of process safety rigor that leaves no room for shortcuts. Our founder has personally led the HAZOP and ATEX classification of a 3 MW electrolyzer — it isn't a box we tick, it's the discipline we specialize in.
ATEX classification
Hazardous area classification for explosive atmospheres (ATEX) at hydrogen facilities, in line with European regulation, covering electrolyzers, storage and refueling points.
HAZOP
HAZOP (Hazard and Operability) studies to identify and mitigate process deviations in green hydrogen plants, applying the methodology and criterion of someone who has led them on real projects.
SIL (Safety Integrity Level)
Safety Integrity Level (SIL) determination under IEC-61511 for the safety instrumented systems of your hydrogen plant.
Risk studies
Quantitative and qualitative risk analysis (QRA) for hydrogen facilities, including dispersion modeling, thermal radiation and explosion overpressure.
Storage, compression and hydrogen refueling stations
We design every link in the green hydrogen value chain, from production to the point of end use.
Hydrogen storage
Engineering of pressurized hydrogen storage systems and their associated vessels (type I to IV), sized to the demand profile and with ATEX and SIL safety criteria built in from basic design onward.
Hydrogen compression
Specification and selection of hydrogen compression systems — a critical piece of equipment in any refueling station or high-pressure storage project — focused on operational reliability and total cost of ownership.
Hydrogen refueling stations
Engineering of hydrogen refueling stations for heavy and light mobility, integrating storage, compression and dispensing in line with AFIR and applicable safety regulation.
Integration with power generation
Integration of electrolyzers with renewable generation (solar PV, wind) and the existing power grid, optimizing the sizing balance between generation, electrolysis and hydrogen storage.
