H3X Technologies

That's a wrap for Reindustrialize! Incredible event with incredible people. We showed some of the new products we've been cooking up in the lab. 1. HPDG-30 - 30kW (40hp) hybrid powerplant 2. HPDM-90S - 90kW (120hp) submerged propulsor 3. HPDM-180 - 180kW (242hp) integrated motor drive 4. HPDM-500-2X - 1MW (1341hp) integrated motor drive Thank you to everyone who stopped by!

Our CEO, Jason Sylvestre, and CTO, Max Liben are heading to Reindustrialize next week where we will be unveiling something big. Our team has been heads-down for a year and its time to show the world what we've been building. Come find our booth 🚀

Dyno testing the HPDM-180D integrated motor drive ⚡

We've been heads-down focused on execution: build, test, ship, repeat. This past week, H3X signed its 20th customer. Every new program reminds us how wide the aperture is for high power-density motors -- aircraft, ships, auvs, ground vehicles, and platforms we couldn't have imagined when we started this company. Our production pipeline behind these programs is stronger than ever, and we're gearing up to support the ramp. H3X is building the next great American electric motor company to power the future of aerospace, defense, and marine. If that mission resonates, come build with us!

We're excited to pull back the curtain on our HPDG-30 hybrid powerplant in the latest issue of Uncrewed Systems Technology. We go deep in the weeds on the tech and why this product is a key enabler for unlocking more payload and range for unmanned systems. Gen 1 benchtop systems are shipping to select customers now. The flightworthy version will be available later this year. Huge thanks to Rory Jackson for the excellent writeup. 👇 Link to the full article in the comments

A new era of megawatt-class power 1MW | 100kg

HPDM-500 loading... ⚡ Made using laser powder-bed fusion (DMLS) metal additive manufacturing on a NXG XII 600 system by Nikon SLM Solutions.

📦 HPDG-30 SN2 is crated up and ready to ship to its first customer! We’ve accumulated ~60 hours of runtime at max continuous power on our hybrid genset and are increasing endurance daily as part of our reliability buildup. Measured Performance: - Electrical Power Out: 25kW electrical out at 5900ft (29.7kW equivalent at sea level) - Specific Fuel Consumption at max power: 624 g/kWhr - SFC at 10kW (optimal): 485 g/kWhr - Fuel Burn at max power: 5.95 gal/hr This aligns closely with our design model, and measured SFC is actually better than predicted 🤘 Next phase: Transitioning to the flightworthy config. The two external cabinets were intentionally oversized for R&D flexibility - our production-intent electronics architecture consolidates that functionality into a single 7" × 7" integrated PCBA.

Over the past few months, we have seen demand skyrocket for compact megawatt-class diesel gensets across marine and industrial markets - driven by US shipbuilding initiatives, mobile AI datacenters, and oil & gas. In response, H3X is developing a modular 2MW genset system built around our HPDM-500 generators and a custom developed gearbox. Our first implementation is with a CAT C32B engine, but the system can bolt up to any engine from 500kW to 2MW with an SAE 0 interface. Key value adds: ✅ Compact footprint: C32B system is ~9 ft shorter than conventional gensets at this power level - critical for hybridized ships where weight and space matter ✅ Native high-voltage HVDC output (600–800 VDC): Integrated power electronics provide direct DC output, eliminating standalone rectifier cabinets and reducing conversion losses (~99% efficient). This architecture is well-suited for modern DC-distribution systems, including emerging 800 V-class data center platforms. ✅ Fault-tolerant architecture: The multisector design of the HPDM-500 enables graceful degradation and continued operation in the event of component-level faults—critical for mission-critical marine and industrial applications.
