Oil pipeline energy storage system

What is repurposing offshore pipeline as energy storage?

Repurposing offshore pipeline as energy storage (ROPES) is a concept that is being investigated by a partnership of offshore projects and services specialists Subsea 7 and offshore energy storage startup Flasc. Flasc was founded as a spinoff from the University of Malta in 2019 and is based in the Netherlands.

What are the applications of offshore energy storage?

This technology can be used in a variety of applications, like power storage for offshore assets, offshore fueling stations for ships, renewable energy storage with offshore wind turbines, or common storage of ammonia for fertilizer plants. How does it work?

How can I store energy directly on the seafloor?

Contact us. With our new subsea energy storage system, based on our membrane-based storage solution for oil and chemicals, you can now store liquid clean energy, such as ammonia or e-methanol, directly on the seafloor.

Can pipelines be used as pressure vessels in Hydro-Pneumatic energy storage?

The partnership of Subsea 7 and Flasc has a plan to use out-of-service pipelines as pressure vessels in a hydro-pneumatic energy storage concept. The first Flasc HPES prototype deployed in Grand Harbour, Malta, in 2018. Source: Flasc.

What is a Subsea energy storage system?

The subsea energy storage system consists of the following main elements: storage units, a fluid transfer and refilling system, heating and circulation system, control and instrumentation, power supply, and structure and foundation. An example with a fixed platform with five 5,000 m³ storage units, gives a total storage volume of 25,000 m³.

What type of pipelines are used in the oilfield site?

According to the preliminary study of the group , the current conventional pipelines used in the oilfield site are: steel pipe size Φ282 × 4 mm, packaging a layer of phase change material outside the pipeline can effectively improve the insulation effect of the pipeline.
