What EST-Floattech does
EST-Floattech B.V. is a Dutch privately held company that designs, manufactures, and services type-approved lithium-ion energy storage systems for the maritime industry. The company was formed in 2015 through the merger of Floattech (superyacht electrical integration, founded 2005) and ESTechnologies (maritime battery management systems, founded 2009), and operates from a headquarters and production centre in Badhoevedorp, Netherlands. Its Octopus Series platform spans 100 kWh to multi-MWh configurations, supports both NMC and LFP chemistries, and integrates via Modbus TCP/IP with vessel energy management systems through proprietary String and System Controllers. The platform holds type approvals from five IACS-aligned class societies (DNV, Lloyd's Register, Bureau Veritas, RINA, ABS), ISO 9001:2015, and ES-TRIN for inland navigation.
The company's revenue model combines hardware sales of the Octopus modules (High Energy, High Power, Lite, LFP) and containerized solutions (50 kWh to 2.8 MWh), professional services for installation and commissioning by SCC-certified engineers, BMS consultancy for maritime and adjacent sectors, and a subscription-based Remote Monitoring & Management service. Go-to-market is direct enterprise field sales to shipbuilders (e.g., Damen, Wight Shipyard, Holland Shipyards Group), system integrators and propulsion OEMs (notably Rolls-Royce mtu under a 2024 framework agreement), and vessel owners or port authorities across ferries, inland shipping, cargo, tugs and workboats, defense, and aquaculture. By 2025 the company had delivered over 300 projects for 80 customers in 24 countries and self-reported the position of world's second-largest maritime battery supplier by project count (achieved in 2021).

EST-Floattech competitors and assessment
Company assessmentDirect peers
- Corvus Energy: Norwegian/Canadian-headquartered maritime battery storage specialist and historically the world's largest maritime battery supplier. Directly comparable as a marine-certified ESS manufacturer with DNV/Bureau Veritas/Lloyd's approvals, containerized products, and a global installed base across ferries, offshore and commercial vessels.
- Leclanché: Swiss lithium-ion battery systems manufacturer with a dedicated e-Marine division supplying type-approved battery systems for ferries, river vessels and commercial ships. Comparable on chemistry-agnostic (NMC/LFP) modular maritime packs and DNV/ Bureau Veritas-certified deployments.
- Echandia: Swedish maritime battery systems specialist focused on LFP-based heavy-duty energy storage for ferries, offshore and defense vessels. Closely comparable as a European maritime-certified ESS pure-play competing for similar ferry, defense and offshore electrification contracts.
- Shift Clean Energy: Canadian/Norwegian provider of modular marine energy storage (formerly PBES) with type-approved battery systems for ferries, offshore vessels and tugs. Directly comparable on maritime-certified modular packs, containerized form factors, and ocean-going vessel customers.
Broad incumbents
- Wärtsilä Energy Storage: Major marine technology and energy systems incumbent offering hybrid propulsion and grid-scale energy storage. Overlaps with EST-Floattech in vessel hybrid/electric propulsion but as part of a much broader portfolio including engines, integrated bridge systems and grid services.
- ABB Marine & Ports: Global electrification, propulsion and automation supplier for commercial vessels. Overlaps with EST-Floattech where shipyards bundle energy storage with ABB's electric/hybrid propulsion systems, posing competitive bundling pressure.
- Saft (TotalEnergies): Industrial battery manufacturer (lithium-ion, nickel-based) serving marine, rail, aerospace and grid. Comparable as a type-approved battery system provider for maritime vessels but operating across a much wider industrial portfolio.
Emerging players
- Akaysha Energy: Australian battery storage developer increasingly active in shipping-adjacent and grid-scale ESS. Relevant as an emerging large-scale battery storage competitor whose scale and capital could divert resources toward maritime customers.
- FREYR Battery: LFP battery cell manufacturer scaling gigafactory capacity. Relevant as an upstream cell supplier (and potential competitor via vertical integration) whose LFP cells increasingly feed into maritime and commercial vehicle ESS markets.
- Kreisel Electric: Austrian high-performance battery systems specialist with immersion-cooled technology serving marine, off-highway and commercial EV markets. Comparable on premium, compact maritime/industrial battery packs with differentiated cooling architecture.
