Green hydrogen, engineered end to end.
We bring hands-on hydrogen and ammonia industry experience to your green hydrogen and derivatives projects, from feasibility and engineering through equipment supply, EPC and commissioning to full operation, under turnkey, EPCM or build-own-operate models.
100+
Years of combined plant operating experience
7
Hydrogen and ammonia sites commissioned and operated
200+ KTPA
Ammonia capacity across 11 centres
3
Countries with delivered projects
How we work
One partner from study to operation.
Hydrogen projects usually pass through separate consultants, EPC contractors, equipment vendors and operators. We bring those roles together.

O&M and BOO
The usual approach
Multiple vendors, multiple contracts
A consultant, an EPC contractor, an equipment supplier and an operator, each with its own scope.
- Design decisions made without operating experience
- Interfaces between packages left to the owner
- No single party accountable for performance
The Hydrovolt model
One partner, one accountability
Hydrovolt carries the project from the first study to stable operation.
- Designs shaped by engineers who commission and run plants
- Electrolysers, balance of plant and construction integrated
- One point of contact through commercial operation and beyond
What we do
Three ways to work with us
A plant delivered turnkey, hydrogen supplied from a plant we own and run, or expert support at any stage of your project.
01
Lump-sum turnkey
EPC or EPCM delivery of green hydrogen, ammonia and methanol plants, with single-point accountability through to commercial operation (COD).
- EPC
- EPCM
- Electrolysers and balance of plant
- Single-point accountability to COD
02
Build-Own-Operate
An OPEX model: customers buy hydrogen, not a plant. We build, own and operate the plant at your site and supply against an agreed offtake.
- Hydrogen as a service
- We own and operate
- Supply against offtake
- Green hydrogen, ammonia or methanol
03
Technical services
Stand-alone expertise for plant owners, EPC contractors and OEMs, at any stage of a project, from the first feasibility study to long-term operation.
- Feasibility, pre-FEED and FEED
- Detailed engineering
- EPCM and PMC
- Installation and commissioning
- O&M and asset management
Technical services
Expertise at every stage
Engage us for the whole project or a single stage. Each service is available on its own, for plant owners, EPC contractors and OEMs.
01
Consulting, feasibility, pre-FEED and FEED
Technical, economic and environmental assessment, technology selection and front-end design that make hydrogen projects bankable.
02
Detailed engineering
Construction-ready engineering for hydrogen generation units, balance of plant, derivatives synthesis and storage.
03
EPCM and PMC
Engineering, procurement and construction management for the owner, or project management consultancy on the owner’s side.
04
Installation and commissioning
Installation, pre-commissioning, commissioning and ramp-up, drawing on start-ups at India’s largest refineries and fertiliser plants.
05
Operation, maintenance and asset management
Trained technicians and engineers who monitor, maintain and troubleshoot to keep plants running at maximum uptime and efficiency.
