ENERGY BALANCE

Before starting any design or modification of a system involving energy (it is almost all systems today), it is necessary to make an energy balance. This approach is relatively similar to usage analysis, and makes it possible to define clear objectives in terms of consumption, storage, and production where applicable.

AUTONOMY OF BUILDINGS

It is now possible to make buildings self-sufficient in energy (electricity or heat). Water autonomy, depending on the regions and uses, can also be sought. This helps to overcome potential supply problems. On the other hand, finding the right energy mix makes it possible to rationalize costs and minimize the payback period.

VEHICLE AUTONOMY AND ENERGY OPTIMIZATION

Some vehicles can become energy autonomous. For others, optimization aimed at reducing consumption and adding or increasing production must be carried out at the start of the design. This approach will influence the technical and equipment choices in all of the project.

AUTONOMY OF MARINAS AND HARBOUR FACILITIES

Marinas and harbour facilities have large areas that can become electricity producers, in order to power dock terminals or other functions. Depending on the location, different sources of energy can be exploited: the sun of course, but also swell or current, depending on the area in which the installation is located. The energy produced can be consumed locally, reinjected into the network, or stored, in particular by producing hydrogen on site, by electrolysis of water which is present in abundance.

NEW ENERGIES

Behind this term lies the notion of energy mix. We will look for the most locally available energies, hybridize them according to their production cycles and the need identified in the energy balance, then complete with the network, always bearing in mind that it is better to use energy local, while for 1 kW consumed on the network, it will be necessary to produce 2.54 kW upstream.

STORAGE AND H2 SOLUTIONS

One of the applications of the energy balance is the determination of the necessary storage capacity. Depending on this capacity and the input and output flows, we will determine the type of storage technology, from solid solutions (batteries, supercapacitors, etc.), to hydrogen, via potentially more exotic solutions (inertia, mass transfers…)
