A NET ZERO FUTURE - SUBSEA BATTERY STORAGE

Driving emission reduction and integrated energy for subsea assets

As the subsea oil & gas industry evolves through the energy transition, it’s essential to keep the lights on at existing assets whilst simultaneously adopting new and better ways of working to meet the industries net zero targets.

EC-OG’s Halo smart battery storage and energy management technology provides the industry with tools to do just that; deliver emission reduction targets and build integrated energy systems for subsea and offshore assets.

Halo is EC-OG’s in-house developed Lithium-ion battery architecture and energy management system. Designed specifically for the demanding subsea environment, Halo provides a power and communications gateway to subsea assets using modular and scalable battery energy storage as a reliable and flexible power supply.

Adaptable for range of applications, Halo is primarily offered as a seabed power solution for brownfield and greenfield oil & gas subsea production control systems. A host of other subsea applications include autonomous vehicle recharging, seabed sensor packages, CCUS injection wells and over-the-horizon communication systems. EC-OG’s Intelligent Energy Management System is the beating heart of the Halo system. It provides the intelligence to accept charge from a wide range of intermittent sources, including wave, tidal and wind energy. Other unconventional forms of offshore energy generation such as underwater fuel cells, floating solar and even maintenance charging from existing subsea umbilical cables can also be accepted, providing an unrivalled range of charge options to the operator.

Brownfield power supply problems, power bottlenecks on existing assets and all-electric subsea systems all bring demanding and complex subsea power needs. Halo addresses these issues by providing an adaptable smart battery architecture that can be configured to provide the required power and energy to a subsea asset as either a retrofit or integrated solution. With the intelligence to operate with marine renewable energy converters, Halo provides the gateway for clean energy systems to help reduce the carbon emissions of offshore operations.

Halo as a standalone seabed, smart battery package is a commercially ready technology, with renewable energy integration for battery recharging available ‘out-of-the-box’. This means that a Halo system of several hundred kWh capacity (scalable) and an AC or DC power output (configurable) can be delivered in as little as 12 weeks from receipt of order.

In addition to subsea production control systems, the need to decarbonise offshore activities and an increase in demand for remote operations presents a unique opportunity for innovative power systems and smart battery technologies. Not least, widespread adoption of autonomous and residential subsea (and surface) vehicles is just round the corner.

Halo is an enabling technology for marine autonomy, providing a reliable power source for in-situ recharging of vehicles in the marine environment, allowing longer missions with a reduced reliance on expensive, manned surface vessels.

EC-OG’s Intelligent Energy Management System is the beating heart of the Halo system. It provides the intelligence to accept charge from a wide range of intermittent sources, including wave, tidal and wind energy. Other unconventional forms of offshore energy generation such as underwater fuel cells, floating solar and even maintenance charging from existing subsea umbilical cables can also be accepted, providing an unrivalled range of charge options to the operator.

EC-OG have the capabilities and expertise to offer custom battery products and systems for subsea, offshore, onshore and industrial applications. In-house design, prototype, qualification and manufacturing services can be undertaken, leveraging the companies multidiscipline engineering expertise built up from the companies heritage in subsea engineering and critical production infrastructure design.

With a constant focus on safety and dependability, EC-OG’s adaptable Intelligent Energy Management System and battery monitoring software places EC-OG as an ideal partner for the development of battery products and power systems to meet the energy industries emission reduction targets.
