Government-Funded Technology Development: Hydroplane has executed U.S. Department of Defense SBIR/STTR programs supporting hydrogen fuel cell propulsion and power-generation technology for aviation and defense applications.
Multi-Domain Platform: A common modular fuel-cell architecture is being developed for aviation, maritime, mobile power, microgrids, and unmanned systems, allowing technology developed in one application to transfer across multiple government missions.
Customer-Funded Development: Hydroplane’s development model emphasizes government-funded R&D, customer-funded technology development, and early revenue
Integrated Systems Engineering: In-house capabilities span fuel-cell stack development, hydrogen systems, thermal management, power electronics, controls, propulsion integration, and system-level testing.
Defense & Government Experience: Hydroplane has performed technology development activities with the U.S. Air Force, U.S. Army, and U.S. Navy/Department of the Navy, as well as state and public-sector agencies.
Zero-Emission Power: Hydrogen fuel cell systems produce electricity electrochemically, with water and heat as the primary byproducts during operation, enabling zero direct CO₂, NOₓ, and particulate emissions at the point of use when operating on hydrogen.
