The Capstone Microturbine is in a class of its own. With over 100 technology patents, these systems combine an aero-derivative turbine, a magnetic generator, and advanced inverter-based power electronics. The true beauty of this technology lies in Capstone’s patented air bearings, which allow for zero friction and require no lubrication oil or cooling system.
Oh, and did we mention? The Capstone Microturbine has ONLY. ONE. MOVING. PART.
Vergent is proud to offer this unparalleled clean energy technology to North America, which we’ve done since 2014.
Vergent provides customized microgrid solutions and on-site energy technology systems to help customers meet their carbon reduction, energy savings and resiliency goals. Microturbines run on natural gas, landfill gas, digester gas, renewable natural gas (RNG), associated gas, liquid fuels, and even hydrogen. Microturbines are well-suited for many types of heat recovery, whether hot water, steam, chilled water, or process heating.
In addition to generating power and heat year-round, the Capstone microturbines can operate as life-safety backup generators to power critical loads during emergencies. Many customers use CHP to extend – or avoid – costly replacements to their existing HVAC equipment. Our specialists will customize and engineer the heat recovery solution for each project based on its unique needs.

The air bearing allows the microturbine to operate with zero friction and zero “wear and tear”. The critical Capstone technological innovation is the use of air bearings. Capstone is the only company that uses air bearings in the hot section of a gas turbine. Air bearings enable the microturbine to operate without the use of oil or other lubricants. There is no oil in the Capstone microturbine, which means no oil changes. The system is also air cooled, so there are no coolants or separate cooling systems used in the microturbine.
Unlike reciprocating engines which have hundreds of moving parts, the Capstone microturbine has only one single moving part. The turbo-generator shaft rotates at extremely high speeds to produce power as cleanly and efficiently as possible. Because the microturbine has only one moving part, there is less likelihood of system failure or need to maintain and repair. The shaft contains the generator, compressor and turbine on a single assembly, rotating at up to 96,000 RPM.
Vergent utilizes microturbines that provide customers with one of the cleanest generation technologies available today. Considerably cleaner than the cleanest reciprocating engines, microturbines are certified by the California Air Resources Board which demands the strictest emissions limits in North America.
CHP systems contribute to a cleaner grid because they can produce energy so efficiently. Generating and consuming energy at the same location means that microturbines eliminate power line losses and CHP utilizes the waste heat instead of emitting it into the atmosphere.
Injector staging allows for high part load efficiency. Continuous combustion creates combustion stability and low emissions. Modularity allows for maximum efficiency and resiliency.
The use of smaller power blocks allows Capstone to deliver the most efficient generated power at partial loads. The one-megawatt package, for example, contains five 200kW power bays allowing it to operate at lower intervals at maximum efficiency by staging the individual bays as load increases. Each bay can operate independently, and maintenance can be performed on one bay at a time while the others continue to generate
Backed by the Capstone Factory Protection Plan (FPP), there is no part or service that is excluded from coverage during the term of the agreement. The FPP is a fixed price for the term, with no inflation or overages.
Microturbines can operate on a variety of fuels, such as natural gas, biogas, diesel, or propane, allowing for adaptability to local fuel availability and reducing dependence on a single fuel source.
Capstone continues to expand and develop new fuel standards including for Hydrogen. Currently Capstone microturbines can safely run on a 30% hydrogen - 70% natural gas mix, and is targeting a 100% Hydrogen microturbines retrofit kits in the next few years.
Due to their small footprint and lighter weight, microturbines can be easily integrated into existing buildings or facilities, minimizing the need for extensive construction or modifications.
This includes fitting in elevators, basement, parking garages and other tight spaces simply too small for other equipment types.
A microgrid is a distribution network that incorporates a variety of distributed energy resources (DER) that can be optimized and aggregated into a single system. The integrated system can balance loads and generation with or without energy storage and is capable of islanding whether connected or not connected to a traditional utility power grid.
Distributed energy resources typically include dual-mode microturbines, reciprocating engines, solar photovoltaic (PV), wind turbines, fuel cells and battery storage.
Microturbines can function in both grid-connected and off-grid modes, providing energy security and resilience, particularly during grid outages or in remote locations.
Microturbines can be connected to electricity grids, and in the event of a widespread outage, can disconnect from the main grid to operate independently and supply electricity to homes and businesses that are connected to the microturbines electricity network.
