A reception in a barn or marquee runs festoon lighting, the band or DJ's PA, the caterer's fridges and warmers, a coffee cart and the bar chillers. Speeches need the microphone to stay on. Most of that fits within 15 kW. The caterer's ovens are the one to check, because several large electric ovens at once can approach the limit on their own.
The fuel cell has no engine, so there is no rumble during the vows or the first dance. The battery and inverter switch over instantly if the grid drops, so the lights do not flicker and the playlist does not stop.
For venues on a long rural line that suffers from outages in wind or storms, that means a couple is not choosing between a dark reception and a loud diesel generator parked behind the marquee, filling the night air with fumes.
How it works →
The system charges on off-peak power during the week and holds hydrogen for weeks at low pressure. A venue running weekend events can top up between them. Round trip is 30% or less, so the energy costs more than the grid. Its value is in protecting events that cannot be rescheduled.
Fridges, warmers and lighting, yes. Several big electric ovens at once can push toward or past 15 kW. Venues may keep some cooking on gas or use a larger setup sized in the pilot.
There is no engine and no exhaust. Fans and pumps make a quiet hum that is easily lost under a string quartet. It would be placed well away from the ceremony lawn and the marquee, in a ventilated enclosure agreed with the venue and installer.
This is designed as a fixed installation for a venue that hosts events every season. Mobile use for one-off weddings in paddocks would raise different safety and logistics questions and is not part of the current plan.
Pilot installs go to people on this list first. Rural homes, farms and remote sites especially. No spam, no payment.
