Hyliion (HYLN) The Gateway Conference 2025 summary

Vision and market need

• Envisions on-site, distributed power generation for facilities, offering cleaner, cheaper, and more reliable electricity than the grid.

• Anticipates massive growth in electricity demand, especially from data centers and electric vehicles, outpacing current grid and transmission capabilities.

• Regulatory changes in regions like Ireland and Virginia require new data centers to provide their own power, highlighting the need for local generation.

Technology and product overview

• Utilizes a four-shaft linear heat generator based on Stirling engine principles, enabled by advanced 3D printing for efficiency and compactness.

• Each unit produces 200 kW; systems can be stacked or scaled up to 2 MW enclosures for large applications.

• Fuel-agnostic design allows operation on over 20 fuel types, including natural gas, hydrogen, diesel, propane, ammonia, and even nuclear heat.

• Achieves up to 50% fuel-to-electric efficiency, surpassing typical grid power plant efficiency.

• Features ultra-low emissions and low noise, with external flameless oxidation and exhaust recirculation for NOx and CO reduction.

Market applications and customers

• Target markets include data centers, military (notably the Navy and Air Force), oil and gas, waste management, EV charging infrastructure, and prime power for commercial facilities.

• Secured a LOI with a major data center provider for 70 MW of generation and a $20 million Navy contract for autonomous vessel power.

• End customers range from infrastructure builders for hyperscalers, military branches, oil and gas companies, landfill operators, to facility owners supporting EV fleets.
