Overview
Founded in 2026 in Washington, D.C., Drogue is pursuing ocean thermal energy conversion (OTEC) for floating data centres. Its proposed design circulates seawater through a cooling and heat-exchange system and uses a closed ammonia working-fluid loop to drive a turbine, condensing the working fluid with colder water from roughly 1,000 metres down.
The first multi-megawatt demonstrator is only planned for early 2028 on a conventional ship; later larger floating platforms are a proposal. In a November 13, 2026 direct interview the CEO disclosed that the company had raised $20M across unspecified financing stages, with named VC backers but no named lead.
American Bureau of Shipping approval in principle is a preliminary design review, not an operating or marine deployment certification.
Why Drogue is interesting
Drogue founder Sam Sipe disclosed $20M in backing in an on-the-record TechCrunch interview published November 13, 2026. The company wants to put a multi-megawatt prototype at sea in early 2028, using warm surface water, cold deep water and an ammonia-cycle turbine to power and cool servers. No fundraise stage, round lead, commercial plant, valuation or contracted capacity has been established.
Product & use cases
ILLUSTRATIVE FUTURE DATA-CENTRE BUYER TOUR — NOT A CUSTOMER DEPLOYMENT: (1) A hyperscaler or colocation operator faces long queues for grid-connected land sites. (2) It evaluates Drogue's proposed ship or offshore modular data-center offering against terrestrial power-purchase agreements, cooling, fibre capacity, latency, marine access and regulatory permissions. (3) The floating plant would circulate warm surface seawater past computing equipment and use its residual heat to vaporize ammonia, drive a turbine and condense the ammonia with cold deep-sea water. (4) Data would move to and from shore through telecom links rather than transmitting electric power to land. (5) Before contracting capacity, a buyer would require independent measured net megawatts after pump loads, actual server uptime, storm resilience, coastal permits, fibre route, environmental assessments, service pricing and financial guarantees. The company plans a prototype for early 2028: this is prospective procurement, not tested performance.
- Large AI operators might explore shipboard power and cooling where terrestrial grid connections are severely delayed.
- Colocation operators could compare an offshore utility-plus-compute bundle with conventional grid connected facilities, but bandwidth, staffing and sea-state constraints differ.
- Ocean thermal developers could use data-centre demand as an on-site power buyer, avoiding long submarine electric transmission to shore, if net generation proves economic.
Key facts
- $20M of disclosed backing reported November 13, 2026 directly by founder Sam Sipe to TechCrunch; financing stage, individual tranche size, legal date, valuation and lead investor not publicly specified.
- A multi-megawatt floating data-centre prototype aboard an existing vessel is intended for early 2028; no at-sea power-generation results have been published.
- The proposed OTEC cycle uses warm seawater and deep cold seawater with an ammonia turbine loop; thermodynamic and marine-engineering feasibility depends on the actual temperature gradient, pipe pumping work and net electricity output.
- American Bureau of Shipping design 'approval in principle' is a preliminary assessment; it is not proof of class certification, operating safety or build completion.
- Named backers include XYZ Venture Capital, Toyota Ventures, Tamarack Global, Dream, FDVC, Garuda Ventures, Flexcap, Boost VC and Slow Ventures; none was explicitly identified as financing lead.

Competitive landscape
Edge: Potential integration of cooling and power generation on a floating compute platform, avoiding onshore grid-delivery delays; however, marine pumping losses, low OTEC temperature difference, corrosion/biofouling, ship maintenance, data fibre and environmental permits could outweigh claimed benefits. No net power-production, commercial unit economics or verified customer contract has been published.
Feasibility remains research/deployment stage, not production infrastructure. Ocean-surface/deep-water temperature differences are small, leading to low theoretical thermal efficiency; pumping water from depth and maintaining 1,000-meter seawater pipes must be accounted for when calculating net megawatts. A 2028 shipboard demonstration, weather resilience, salt corrosion, biofouling and fibre connectivity require independent qualification. Sipe's 8–10-year data-center project estimate and 10x AI demand are personal comparisons, not independently measured sector averages. The $20M sum may span financing tranches: do not invent a $20M priced seed or Series A.
-
Terrestrial hyperscale data centers incumbent
Proven infrastructure but grid interconnection and permitting can constrain new supply; TCO and latency comparison is needed.
-
Nuclear or gas-backed modular data centers alternative
Alternative off-grid/behind-the-meter power strategies with different fuel, permitting and reliability risks.
-
Makai Ocean Engineering and OTEC developers adjacent
Alternative OTEC technology expertise, generally not a fully integrated commercially deployed AI-data-center offer.
-
Subsea cooling or floating facilities adjacent
Ocean cooling may be possible without OTEC power generation; not a like-for-like on-site generation substitute.
