Global warming is causing a major ice retreat from the North Pole. From now on, this retreat allows almost permanent movement between East and West off the coast of the Russian Federation along the Northern Sea Route (NSR). For a long time, navigators have been trying to use this route which significantly reduced the distance between continents. The amount of freight that currently travels on the NSR will inevitably increase in the coming years. To reduce environmental risks, one possible option is not to supply ships with heavy fuel oil. The ships could then be electrically powered and navigate in stages from one port to another along the route to refuel for energy. This electrical energy can be produced on site from renewable energy sources. In this article, a first feasibility analysis is outlined, taking into account the tonnage constraints for navigating on a possible route for the NSR, the cost of energy production and the possible location of several ports of call. Under current economic conditions, the solution would not be profitable as it stands, but should become so at a later stage, which justifies starting to think about a future full electrification of navigation on the NSR, which will also contribute to the economic development of the Russian Federation northernmost regions.
There are many solutions for storing energy, they can be either mechanical, thermal, chemical, electrochemical or electrical. In a context of smart-grid and micro-grid development, it is necessary to be able to store electrical energy at various points in the network: at the source for intermittent resources, in the network itself to have reserves to ensure exploitation and in consumption areas. Each solution is more or less relevant depending on the storage needs in terms of both power and energy. The evolution of electricity demand in the Russian Federation is a good example to illustrate this issue, especially since it is now planned that all new construction will have an energy storage system, so as to contribute to a better overall exploitation of the network. For intermediate storage, on the network, there is definite potential thanks to the old mines, in particular, that can be developed to store energy in the form of compressed air. In high consumption sites, it is also possible to use storage in the form of large energy banks made up of batteries.
To produce sustainably, an optimal solution must be determined that ensures that the production of future generations is not compromised. New demands and the introduction of renewable energy imply adding energy storage to regulate the grid. This review aims to synthesise the state of the art of research on energy production and storage with information and expert opinions available to the general public, with an application to the French model. French publications online are used for illustration. A comparative analysis is proposed to recommend ways to improve technicality and to guide decision-makers on the levers to be favoured for each specific storage needed, taking into account the principles defined by the United Nations to define Sustainable Development. Solutions considered rustic can also contribute to the optimisation of energy resources by mechanically storing energy, but the choice of decision-makers will always be fundamental to imposing either soft or hard changes, whereas some attitudes seeking only to favour present advantages are the very antithesis of the principle of sustainability.
