The engineering group SEGULA Technologies is unveiling REMORA Home, an innovative energy storage solution for homeowners with photovoltaic panels or domestic wind turbines who are keen to become energy independent and reduce their ecological footprint. This solution will enable them to store surplus energy for future use.

REMORA Home is based on a patented isothermal air compression and decompression process.

A discreet and intelligent ally for connected homes

Easily integrated into any type of home, the system consists of two parts:

• Firstly, a reversible compressor to be connected to the solar panels, which converts the surplus energy produced into compressed air. Similar in size to a conventional water heater, this compressor can be installed in the house, garage or cellar, for example.

• Secondly, a cabinet housing the compressed air cylinders used for storage, which can be placed either indoors or outdoors.

When energy production is insufficient – in the absence of sun or wind, for example – this air is then released and converted into electricity, guaranteeing continuous and reliable energy autonomy.

To control the whole system, an intuitive mobile application enables users to monitor their own consumption and reduce their electricity bills. The application provides personalised recommendations, can be used to check that the system is operating correctly, and can be connected to certain household appliances to optimise their use.

A robust, low-carbon solution

With an overall efficiency of 70% and a lifespan of at least 30 years, REMORA Home offers an excellent alternative to lithium-ion batteries. The system generates no polluting emissions and, unlike batteries, is made from robust, durable and easily recyclable materials (steel, aluminium).

“The storage of renewable energy, particularly in the home, is a major problem and a key issue for the future. With REMORA Home, we are offering private individuals the chance to optimise their individual production, free themselves from fluctuations in electricity prices and play a full part in the energy transition,” emphasises David Guyomarc’h, REMORA project director and head of R&D at SEGULA Technologies. “This intelligent, sustainable solution is the answer to a growing need for autonomy and efficient energy management in the home.

SEGULA Technologies is thus confirming its ambition to revolutionise the energy storage sector by offering innovative and sustainable solutions for modern households.

The test phase is already well advanced

The test phases, which began in January 2024, have already demonstrated REMORA Home’s ability to store air on a scale suitable for a home with good performance.

In 2025, laboratory tests will focus mainly on energy storage.

SEGULA Technologies then plans to deploy pilots in individual homes by the end of 2026 to test the technology over the long term and user interaction with it. These final stages will enable all the functionalities to be validated before the product enters mass production, with marketing scheduled for 2028.

REMORA Home is an evolution of REMORA Offshore, initially designed to store renewable energy under the sea. This technology is now available in two onshore versions: REMORA Home is aimed at private customers, while REMORA Stack offers large-scale mass storage, particularly for industrial sites.
