Rented hydrogen generators for shoots and events when NCR restricts diesel sets
TL;DR Holdover rents trailer-mounted hydrogen fuel cell generators, with fuel and an operator, to film crews, event organisers and contractors in Delhi NCR during the months when diesel sets are restricted. Production companies pay a day rate. It only works because the load is short, the season is fixed and the alternative is no power at all.
Diesel gensets fill the gap wherever grid power is missing, and India has roughly 75,000 MW of them in the 100–1,000 kVA range alone[1]. In Delhi, smog emergencies keep bringing outright genset bans. One 2016 order banned all diesel sets for ten days, with only hospitals and emergencies exempt[2], and later winters brought more of the same.
That hurts anyone who needs temporary power at a location - outdoor shoots, weddings, exhibitions, road works at night. Batteries cover a few hours of light loads but a lighting rig or a catering kitchen runs all evening. So what do organisers do today? They cancel, pay for grid connections they can't get in time, or run the sets and hope nobody checks.
What it does, in regulatory terms: power rental using compressed hydrogen stored and moved under PESO rules. The generator itself makes no emission claim beyond "no exhaust except water vapour". The hydrogen cylinders and the trailer's pressure vessels need PESO approval.
Holdover runs a small fleet of 20–60 kW fuel cell units with a battery buffer, each on a trailer with a cylinder bank. A crew delivers, connects and stays on site. The customer books by the day and fuel is billed by the kilogram used.
The seed pitched fuel cells as a general replacement for backup gensets, and I've narrowed that down a lot. One big cloud company's 250 kW test ran 48 hours, but the company noted that 48 hours of backup for a whole data centre could need up to 100,000 kg of hydrogen[3]. At India's discovered green hydrogen price of ₹397 per kg[4], that is about ₹4 Cr of fuel per long outage. Short, planned, high-value rentals are where the fuel bill is small enough to pay.
Line producers on ad films and web series, event management firms, and contractors with night work in NCR pay. They already hire diesel sets by the day, and a cancelled shoot day costs them far more than a higher power bill ever will. The buyer is whoever signs for location costs. Holdover doesn't have to beat diesel on price - it has to beat "cancel or delay".
The National Green Hydrogen Mission, approved in January 2023 with a ₹19,744 Cr outlay, named decentralised energy among its pilot areas[5]. Hydrogen now has a discovered Indian price of ₹397/kg from June 2025[4], so fuel cost is finally something you can quote. And every smog season since 2016 has shown that genset restrictions come back[2].
There is no public figure for temporary power rental in NCR, or for days lost to genset restrictions. The firm number is the installed base: roughly 75,000 MW of diesel sets of 100–1,000 kVA across India[1], a share of which sits with rental firms. Treat that as adjacent context, nothing more. Your real test is how many paid rental days you can book in one winter.
A big cloud company and a fuel-cell integrator proved a 250 kW fuel cell could carry servers for 48 hours[3]. Telecom carriers abroad have run fuel cells as backup, and one Caribbean site ran 5 kW for 50 hours[6]. In India, diesel rental firms own temporary power and I found no firm renting hydrogen generators.
The gap is a rental desk that turns up with fuel, permits and an operator.
| Difficulty | Hard (57/100) |
| Starting capital | ₹2.5–4.5 Cr |
| Time to launch | 12–18 months |
The generator is the easy bit. The hard part is the fuel chain, which means a hydrogen supplier, approved cylinders, a licensed storage yard and trained drivers. Each unit is expensive and sits idle for a good chunk of the year unless you find summer work.
Yes, the fuel side is regulated. The generator itself is the easy part.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI with gas safety decisions on site. Leak checks and shutdowns stay with the trained operator.

I'd only try this if you come from the power rental or events business and already have customers. Do not start by building hardware. Lease units and prove demand instead. The first thing to prove is that 10 production houses will book paid days in one smog season at a rate that covers fuel and crew.
Plan for roughly ₹2.5–4.5 Cr, mostly for fuel cell units, cylinders and a licensed storage yard.
Yes. Filling, storing and moving hydrogen cylinders needs PESO approval, and venues need fire-safety sign-off.
Yes, wherever diesel sets face limits at events or sites. Check local gas cylinder rules and how reliable your hydrogen supply is.

Thinking about building Holdover or something close to it? The make-or-break work is a hydrogen supply and storage setup that never misses a shoot day, and that's exactly the kind of thing I help founders plan. If you need a hand, you know where to find me. Talk to Yash →
