Resilient Energy for When It Matters Most
When a disaster takes the grid down for days, essential buildings need power for days — and somewhere safe to keep it.

The challenge
A major disruption does not take power away for an hour. It takes it away for days, across a region, at exactly the moment the buildings that matter most are fullest.
The buildings carrying that load — hospitals, shelters, civic facilities — are usually occupied, often in dense areas, and frequently have nowhere to put a large volume of stored fuel. Batteries sized for a short outage run out. Diesel sized for a long one has to be stored, ventilated, and refuelled while roads may be closed.
How LAVO answers it
Hydrogen held in metal hydride is a different proposition from hydrogen held under pressure. The gas is absorbed into a solid at low pressure and released on demand, which is what makes an on-site reserve reasonable to keep somewhere people are.
The system produces its own hydrogen from renewable supply when the grid is healthy, stores it, and converts it back through a fuel cell when the grid is not. Runtime is a function of how much storage is installed rather than how often a tanker can reach the site.
A fuel cell also produces heat while it produces electricity, and that heat can be recovered rather than rejected — useful in a building that needs hot water and warmth during exactly the period it has lost normal supply.
Wider application in the sector
A system bought for the emergency spends almost all of its life not having one.
The wider case is to stop treating it as equipment that waits. The same installation can shave a facility’s peak demand, hold energy generated on site until the building actually needs it, and island a building or a campus from the grid deliberately rather than only when the grid decides. That turns a resilience purchase into part of how the building is run day to day, which is also what justifies the size of reserve worth holding for the day it is needed.
From there the unit of resilience grows: one building, then a campus with shared storage, then a district where several critical facilities lean on the same reserve.
