THE MGH COMPANY
MGH is an innovative company initially specialized in low-carbon energy solutions in the marine environment. Today, it is dedicated to the development of decarbonizing energies for maritime and aviation applications. In this context, MGH is studying solutions to replace fossil fuels with more respectful energies such as biosourced synthetic fuels, hydrogen or electric propulsion.
Regarding velocity propulsion, in 2019 MGH acquired a stake in the start-up company Zéphyr & Borée, a pioneer in sail transportation, which is carrying the Canopée transatlantic cargo project on behalf of Ariane Group.
MGH has also recently launched the world's first 100% electrically powered pilot boat, which was inaugurated in April 2021. It is within the framework of the Green Pilot project, led by MGH, supported by its partners, the Occitanie region and the Port of Sète-Frontignan, and with the participation of the piloting stations of Sète and Marseille-Fos, that the e-Maguelonne is born after more than 4 years of research and development. Project rewarded in 2018 by the Innovation Trophy of the Port Du Futur and an Innovation subvention contract with the Occitanie region.
MGH has also developed a solution for the massive storage of electrical energy at sea in the form of gravity, which is intended to contribute to the balance of the electrical networks. This solution is protected by patents.

MGH - The Green Pilot Project & The e-Maguelonne
The world's first 100% electric pilotine
Sea pilots lead ships to the entrance of the ports. By night or day, they join the cargo ships that arrive several kilometers off the coast of the port, by means of fast boats called pilot boats. While the ship is still underway, the pilot boat docks alongside the ship so that the pilot can climb aboard via a rope ladder and reach the ship's command post to take it to its dock..
The e-Maguelonne pilot boat has an electric motor with a power of 200 kW. Its 6 on-board batteries are recharged by a fast charging device, installed on the platform, with a power of 120 kW. The capacity of the batteries being approximately 180 kWh, the recharging time of the empty batteries is approximately 1h30. This 12-meter long vessel is capable of reaching a maximum speed of 19 knots, thus allowing the safe embarkation and disembarkation of pilots. It takes about 30 minutes of charging between 2 pilot missions to recover the full capacity of the batteries.
The feedback from the pilots is extremely promising. The 100% electric Maguelonne, powered by its on-board batteries, emits neither greenhouse gases nor pollutants and does not expose its passengers to diesel odors and fumes. In addition, its noise emissions, significantly lower than those of a diesel engine, represent a real comfort for the onboard personnel as well as for the immediate environment of the pilot.
The inauguration of this first 100% electric pilot boat resulting from the transformation of an existing thermal pilot boat offers the maritime industry the opportunity to take a further step in the decarbonization of port activities.
MGH – ZEPHYR ET BOREE
As part of its strategy to encourage the maritime energy transition, in 2019 MGH acquired a 25% stake in the start-up company Zéphyr & Borée, which aims to design and operate merchant ships offering innovative low-carbon transport solutions. These hybrid ships, equipped with sails, aim to consume up to 45% less fuel.
By joining forces with Zéphyr & Borée, MGH wishes to support this innovative system and plans to go further in the maritime decarbonization process by taking on board other technologies such as hydrogen and biofuels.
In 2019, the Nantes-based start-up won the prestigious tender launched by ArianeGroup to transport the Ariane 6 launcher to French Guiana as early as 2022. Thanks to its four 375-square-meter articulated vertical wings and state-of-the-art weather routing, the 121-meter-long freighter will consume on average 30% less fuel than a conventional ship
MGH - OFFSHORE ENERGY STORAGE
Deep sea energy storage
MGH is a patent-pending technology co-invented by Jean-Michel Germa, Richard Perez and Marc Perez that harnesses the vast potential of the oceans to massively store electricity with a minimal environmental footprint
MGH uses gravity potential energy as a vector to store large amounts of energy by transferring large masses between the ocean floor and surface
When there is a surplus of electricity production on the land grid, a motorized lifting device uses the surplus electricity from the grid to lift the weights from the seabed (over 1000 meters) to the surface where they are attached to a floating offshore platform. Storing the weights at the surface allows the electrical energy needed to lift them to be converted into potential gravity energy. The system is fully charged when all the weights are brought to the surface.
When there is a surplus of electricity consumption on the terrestrial network, the weights are hooked to generators and unhooked from the platform. Their descent drives the generators located on the platform and generates electricity. During the transfer from the surface to the seabed, the stored potential energy is released in the form of electricity to the electrical grid. When all the weights reach the seabed, the system is completely discharged.
The floating platform is connected to the electrical grid via a high voltage underwater power line. On land, the cable can be buried underground to minimize the impact on the environment.
The main operational context of the MGH system is to provide storage services at the transmission system level, but it can also be used in direct combination with intermittent renewables such as wind and solar power and make them stable and predictable, thus enabling a higher penetration of renewable electricity.
