Harnessing the power of the sea.
Overview
This one-of-a-kind technology uses the ocean’s currents and tides to autonomously generate and deliver power locally. It is a scalable, vertical axis turbine system that harnesses the energy of moving water and converts it to electrical energy.
Convert. Store. Deliver.
Uninterrupted power supplied to your underwater 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 energy storage system, using our Lithium-ion battery technology.
And finally, electrical power is delivered to your underwater asset, all managed and protected by Verlume’s Intelligent Energy Management System (IEMS).
Key features
Powerhub can be used as a standalone system, in single or multi-turbine array format, or can be customised 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, the most predictable renewable energy resource.
- A seabed-located alternative to wave or wind generators for autonomous subsea power applications.
- Temporary or permanent uninterrupted power supply for underwater assets.
- Integral energy storage, or can be used in conjunction with Halo for larger storage needs.
- 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 Power Remediation
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 Developments and All-Electric
With clean energy solutions, we can contribute to reducing the carbon footprint of your operations. 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. Decommissioning and Remote Monitoring
By using a remote power source to monitor underwater wells, you can strip out all other infrastructure leaving just the wellhead and environmental barriers – saving time and money.
Remote monitoring and measuring is an essential tool for many sectors, and Halo can be used as a power source across an ever-growing range of applications:
- Underwater data gathering and processing
- Decommissioning / well monitoring
- Powering oceanographic sensors
- Internet of things
- Aquaculture systems
- Site / perimeter monitoring and defence
-
04. ROV/AUV Charging
Residency for autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) can offer significant environmental and cost benefits. Reducing the reliance on surface vessels, cuts out high costs and fuel dependency by removing the tether between the vehicle and the surface. But the availability of power can be a challenge over extended periods of residency. That’s where Powerhub comes in.
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.
With its integrated energy storage, Powerhub 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. And as it offers a capacity for a fully regenerative system, even longer periods of underwater residency are now a possibility.
