A refuelable energy reserve designed to complement the campus supply
QEYS Energy is adapting a proprietary ammonia-storage and delivery method from diesel emissions control to stationary power, connecting the reserve to compatible generation and a battery.
Each component has a defined operating role.
The battery would accommodate rapid electrical changes. The stored fuel would support sustained generation through a qualified converter. Replenishment would restore the reserve through fuel delivery rather than grid charging alone.
For the first product, the duty cycle and converter choice will be selected through testing and customer requirements. The public concept does not assume a single conversion route works for every facility.

Natural-gas generation provides a practical integration pathway.
A campus can use gas for routine generation while evaluating stored ammonia for resilience or constrained-supply events. This allows development around existing power equipment and operating practices.
Connect a separate reserve generator.
The gas generator and Reserve converter feed the same site electrical system through appropriate protection and controls. A battery supports transitions. This approach avoids requiring an existing gas engine to accept ammonia-derived fuel.
Evaluate recoverable engine heat.
Engine heat may help support reserve operation where temperature, availability, and heat-transfer performance are suitable. The reserve must still start and sustain its intended duty when gas generation is unavailable; recovered heat cannot be its only outage energy source.
Test compatible engines with a second fuel pathway.
In August 2026, Amogy and 2G reported tests combining ammonia reforming with an engine that also supports natural gas. QEYS could evaluate a similar conversion interface downstream of its storage system, subject to OEM qualification, fuel-quality limits, emissions, and transition testing.
Using two fuels in one engine still leaves that engine as a shared point of failure. The campus redundancy design, independent startup capability, and fuel logistics remain essential.
This is a proposed QEYS development pathway. The industry demonstration is not a QEYS partnership or validation of our storage integration.
Industrial storage expertise applied to critical power
QEYS has acquired a proprietary method for storing ammonia in a solid material and releasing it on demand. Developed for diesel emissions control, the method supplies ammonia to catalysts that reduce nitrogen oxides, or NOx, in exhaust.
We are adapting that storage and delivery capability for stationary power. The application changes from treating exhaust to supplying a fuel reserve for critical computing, building on an industrial approach to handling ammonia.
For stationary power, the value lies in dependable fuel delivery through sustained generation and replenishment. Our development program focuses on that operating capability and its integration into a customer’s power system.
Questions that guide the development program
Can ammonia be put directly into any natural-gas engine?
No. Fuel properties and engine requirements differ. The route discussed here uses compatible conversion and, where applicable, qualified ammonia-derived fuel. It requires OEM review and testing rather than an assumed drop-in substitution.
Could Reserve replace diesel backup?
That is a potential application to test against a defined customer requirement. QEYS must demonstrate runtime, transitions, reliability, replenishment, emissions, and total cost before claiming equivalent or better performance.
Would the reserve be independent of a gas outage?
That is an intended design objective. It requires stored fuel, an independent startup and thermal plan, suitable conversion equipment, and the electrical redundancy needed by the facility. An engine-heat dependency would have to be addressed explicitly.
Does ammonia guarantee zero-carbon power?
No. Lifecycle emissions depend on fuel production, transport, and conversion. Combustion pathways also require evaluation of nitrogen-containing emissions. Lower-carbon performance must be measured for the selected system and fuel supply.
What is already demonstrated by QEYS?
QEYS has acquired the proprietary storage-and-delivery methodology and is developing its stationary-power application. System performance, operating duration, and economics remain part of the validation program.
