What MayMaan Research does
MayMaan Research is a private clean-combustion technology company headquartered in Hollywood, Florida with a regional office in Paris, France. The company develops and licenses a proprietary engine platform called AquaStroke that transforms internal combustion engines to operate on a 70% water and 30% bio-alcohol (ethanol or methanol) fuel blend. The platform keeps combustion chamber temperatures below 900°C to suppress NOx formation while generating in-chamber steam to deliver additional torque, yielding near-zero NOx, SOx, particulate, and unburned-hydrocarbon emissions at diesel-comparable efficiency. Modular architecture allows the same core technology to scale from a 35 kW portable generator (the CE-certified A35) through the AV2 product line up to 3 MW+ industrial systems.
MayMaan commercializes the platform through three revenue streams: direct sale of finished generator and power systems (A35, AV2, turnkey systems up to 3MW), technology licensing to engine manufacturers, OEMs, distributors, and strategic partners who initiate production through certified builders, and professional services covering engineering collaboration, training, proprietary diagnostics, and ongoing product upgrades. Distribution runs through direct enterprise sales (for large industrial users, data centers, EV charging, healthcare, and government/defense accounts) alongside a global network of distributors, strategic partners, and OEM integrators.
The company was founded in 2009 and is led by founder and CEO Doron Shmueli, with Michael Shmueli serving as Vice President of Corporate Communications. In May 2023 MayMaan closed a $30 million Series A round led by Wave Equity Partners. The company has subsequently built a roster of strategic alliances including Vattenfall (May 2023), SPIE Nederland (March 2025), Coulomb Energy Solutions (March 2025), and earlier participation in the PortXL 2022 Rotterdam acceleration program. In June 2025 it formalized the Engine Integration Program to onboard manufacturers, OEMs, distributors, and service partners to AquaStroke drop-in clean combustion. The company operates with 11–50 employees and has not publicly disclosed revenue.

MayMaan Research competitors and assessment
Company assessmentBroad incumbents
- Generac: Largest US manufacturer of backup power generators, directly competing with MayMaan's A35 in residential, commercial, and industrial backup-power applications. Both target the same end customer pain point of reliable on-site power with growing emphasis on lower emissions.
- Cummins: Global leader in diesel and gas engines for power generation, with an emerging clean-energy pivot through Cummins Accelera (hydrogen fuel cells). MayMaan's OEM licensing model specifically targets powertrain manufacturers like Cummins as potential partners or competitive threats.
- Caterpillar: Manufacturer of large diesel and gas gensets serving data centers, utilities, and industrial customers. Caterpillar's installed base and dealer network make it both a potential OEM licensee for AquaStroke and the dominant incumbent MayMaan's drop-in value proposition aims to disrupt.
- Wärtsilä: Major manufacturer of marine engines and grid-scale power plants with active decarbonization efforts including hydrogen-ready engines and future fuels. Wärtsilä is one of the most relevant comparables for MayMaan's maritime and utility positioning.
- Rolls-Royce Power Systems (MTU): Subsidiary of Rolls-Royce producing large gas and diesel gensets for data centers, hospitals, and industrial microgrids. Overlaps directly with MayMaan's modular 35kW–3MW+ power-generation range and data-center backup vertical.
Direct peers
- Capstone Green Energy: Direct competitor in clean, distributed power generation, selling microturbines for combined heat and power, microgrids, and backup applications. Both companies target commercial and industrial customers seeking lower-emission alternatives to diesel gensets.
- Mainspring Energy: Developer of linear generator technology that produces low-emission electricity using conventional fuels. Like MayMaan, Mainspring targets commercial and industrial customers seeking dispatchable clean power that can operate on existing fuel infrastructure.
Emerging players
- Bloom Energy: Leading solid-oxide fuel cell manufacturer targeting data center backup power — the same hyperscaler sustainability-driven segment MayMaan is pursuing with AquaStroke generators. Represents the primary clean-alternative threat to MayMaan's data-center thesis.
- Ballard Power Systems: PEM fuel cell company supplying hydrogen-powered backup systems to data centers, telecom, and industrial customers. Competes with MayMaan for the same backup-power and zero-emission mandates in markets such as Europe and North America.
- Plug Power: Hydrogen fuel cell and electrolyzer company with growing presence in stationary power, data center backup, and industrial mobility. Represents the broader hydrogen ecosystem that MayMaan's drop-in water-ethanol approach is positioned against.
