Harnessing the power of the sea.
Overview
This one-of-a-kind technology uses the ocean’s currents and tides to generate power at a well site, delivering power locally rather than through umbilical cables. Its scalable, vertical axis turbine system harnesses the energy of moving water and converts it to electrical energy.
Convert. Store. Deliver.
Uninterrupted power supplied to your subsea architecture – tailored to you – in three easy steps. First, using remote power generation, Powerhub converts the ocean’s currents and tides into electrical energy. Secondly, that energy is then stored within a state-of-the-art system, using our lithium-ion battery technology. And finally, electrical power is delivered to your subsea asset by combining these core technologies.
Key features
Powerhub can be used as a standalone system, with single or multi-turbine array layout, or can be adapted to suit your specific applications and locations. Here’s what you need to know about this technology:
- Power is generated from ocean currents and tidal streams.
- An alternative to wave or wind generators for autonomous subsea power applications.
- Temporary or permanent UPS for subsea assets.
- Integral energy storage, or can be used with Halo.
- Gravity foundation – single trip deployment and recovery.
- Integrated wireless communication systems.
- Multi-layer safety systems.
- Fully scalable, modular design – configurable for the application.
- Clean energy, low-cost alternative to umbilical power cables.
Powerhub Applications
-
01. Brownfield
Powerhub offers an alternative to electrical cables, which are expensive to install and often need repaired or replaced over time. It’s fully autonomous, providing a regenerative energy source that powers for extended durations. It’s quick to install, too.
-
02. Greenfield
With clean energy solutions, we can reduce the industry’s carbon footprint. Powerhub lets you harness the energy in ocean currents and tides to generate power directly at the point of use – giving more possibilities for extended tie-back distances. For greenfield developments, benefits include:
- A local power source at the well site means there’s no need for the electrical element of a subsea umbilical.
- By enabling all-electric systems, we can remove the hydraulic element of the umbilical, further enhancing the possibility of umbilical-less systems.
- Removing the cables also significantly reduces the cost of extended reach tie-backs, giving opportunities for more marginal developments / hydrocarbon reserves that aren’t economical using today’s industry accepted technology and methods.

03. Remote monitoring
By using a remote power source to monitor subsea wells, you can strip out all other infrastructure leaving just the wellhead and environmental barriers. That means the operator can defer plug and abandonment activities until several assets can be combined in a single campaign – saving you time and money. Powerhub can be used for:
- Subsea data processing
- Powering sensors
- Subsea internet of things
- Decommissioning
- Aquaculture

04. ROV/AUV charging
New autonomous underwater vehicles (AUVs) are becoming more commercially available as an alternative to remotely operated vehicles (ROVs). They reduce the reliance on surface vessels, cutting out high costs and fuel dependency by removing the tether between the garage and the vehicle.
Powerhub can be used as a regenerative energy source for subsea garages. Being a scalable system, energy can be supplied to provide multiple charge cycles for the vehicle and for subsea data processing / transmission to surface.
And with its integrated energy storage, it can be configured to buffer the power supply and act as an accumulator – providing a clean and stable power supply for fast charging, much quicker than what’s available for the renewable energy resource. It also offers a capacity for a fully regenerative system, making even longer periods of subsea residency possible.
