Host a Joule Pilot Site - pioneer the future of ocean-based energy storage.

We’re seeking select partners with access to deep water and a grid connection, such as offshore wind, solar, or wave power operators - to host pilot deployments of Joule’s Modulated Buoyancy Energy Storage (MBES) technology.

Every decade, a few projects redefine what’s possible in clean energy. Hosting a Joule pilot isn’t just participation, it’s leadership. It’s your chance to demonstrate the world’s first scalable, zero-emission ocean storage system and showcase how renewable energy can be stored when it’s abundant and delivered when it’s most valuable.

Why host a Joule pilot?

• Avoid curtailment: Capture energy you’re forced to spill today and shift it into peak-demand windows.
• Monetize timing: Sell stored energy when market prices spike, turning waste into profit.
• Stack revenues: Tap into capacity payments, ancillary services, and congestion relief depending on market rules.
• Complement renewables: MBES installs below the surface, no land use, no freshwater, no emissions, no noise.
• Demonstrate leadership: Be among the first to validate ocean-based long-duration storage at your site.

Ideal pilot hosts:

• Offshore wind, solar, or wave projects facing curtailment
• Ports or marinas with 200 - 500m+ nearby depth (depending on site design)
• Existing or planned grid interconnections
• Interest in market participation for arbitrage and grid services

What we’ll explore together:

• Site suitability (bathymetry, seabed conditions, metocean data)
• Interconnection and control integration
• Dispatch strategies for curtailment capture → peak delivery
• Technical and economic performance validation

We’re highly selective, not every site qualifies. But for those that do, the opportunity to pioneer ocean-based energy storage is unmatched.

If you’re ready to explore a pilot, this is your moment to lead.
