Deployment of an integrated charging solution for electric vehicles powered by renewable energy.
Reducing greenhouse gas (GHG) emissions linked to the building's energy consumption, thanks to the self-consumption of the energy produced via the photovoltaic roof panels. This energy loop, combined with a second-life battery storage system, makes it possible to supply most of the charging stations for the company's fleet of electric vehicles. Intelligent control of the redirection of the energy (produced/stored) also makes it possible to supply the building's other consumption points (electric heating, sockets, lighting, etc.).
Reusing second-hand electric vehicle batteries to store solar energy is one of the keys to the REVE principle.
REVE is a 100% renewable energy (RE) self-consumption recharging offer for companies wishing to quickly switch their vehicle fleet to electric power without changing their type of energy contract:
- A la carte" sizing of the photovoltaic panel installation
- Energy storage using second-hand batteries from electric vehicles
- Supervision system ("WAVE Plateform" application) developed by VINCI Energies, guaranteeing optimal control of energy distribution between the building and the charging stations.
Direct emissions generated by the company's activity.
Indirect emissions associated with the company's electricity and heat consumption.
Emissions induced (upstream or downstream) by the company's activities, products and/or services in its value chain.
Carbon sinks creation, (BECCS, CCU/S, …)
Emissions avoided by the activities, products and/or services in charge of the project, or by the financing of emission reduction projects.
Scope 1 : Conversion of thermal vehicle fleet to electric: reduction of fossil fuels.
Pre-project situation :
Diesel: 71,701 L/year * 2.6 kgeq CO2 = 186 tCO2eq
Post-project situation in the event of a 100% switch from a thermal to an electric fleet:
Diesel: 0 L/year * 2.6 kgeq CO2 = 0 tCO2eq
Balance: 186 t CO2eq avoided
Scope 2 : Direct self-consumption of the energy produced on the roof
Pre-project situation :
130 tCO2eq related to the building
Post-project situation :
37 tCO2 eq linked to the residual electricity consumption from the network (72% saving on the bill).
Scope 3 : Home to work journey - Battery recycling
20% of employees use the charging stations free of charge today
Elimination of 52,800 km per year driven with fossil fuels, at 190 gCO2eq per km, which represents 10.5 tCO2eq avoided. (The KM are not avoided but the energy concerned no longer emits CO2).
Difference in GHG emissions between purchasing new and second-hand batteries
The carbon weight of a new 30 kWh battery is 5 t CO2eq.
According to the proposed methodological note, using a recycled battery is equivalent to 50% less GHG emissions than a new battery, i.e. 2.5 tCO2eq avoided.
Avoided Emissions : GHG emissions become the scope 3 emissions of its customers once the REVE principle is installed.
Quantification : GHG emissions avoided: 192 t CO2eq / year

Details of the calculation or other remarks: According to the proposed methodological note
Transformation of thermal vehicle fleet to electric: reduction of fossil fuels:
Pre-project situation :
Diesel: 71,701 L/year * 2.6 kgeq CO2/l = 186 tCO2eq
Post-project situation (in the event of a 100% switch from a thermal to an electric fleet) :
Diesel: 0 L/year * 2.6 kgeq CO2/l = 0 tCO2eq
Theoretical electricity consumption at charging stations for a 100% electric fleet of 30 vehicles
30 LCVs X 1 charge X 40 kWh = 1,200 kWh / day, i.e. for 1 year at 220 working days = 240,000 kwh.
Electricity (60% self-consumption): 144 000 kWh/year * 0gCO2/kWh = 0 kgCO2
Electricity (40% grid): 96,000 kWh/year * 50 gCO2/kWh = 4.8 tCO2
Balance: reduction of 181 tCO2eq
Grid electricity: 28,000 kWh/year * 60gCO2/kWh = 16.8 tCO2
Electricity (60% self-consumption): 16 800 kWh/year * 0gCO2/kWh = 0 kgCO2
Electricity (40% grid): 11,200 kWh/year * 50gCO2/kWh = 5.6 tCO2
Balance: annual reduction of 11t CO2eq
Use of recycled batteries
The carbon footprint of a new 30 kWh battery is 5 t CO2eq.
According to the proposed methodological note, using a recycled battery is equivalent to 50% less GHGs than a new battery, thus a reduction of 2.5 tCO2eq
We are currently in the design and construction phase.
The HS2 project has a life span of 120 years.

Scope of deployment
REVE is aimed at all companies that have the necessary space to install photovoltaic panels, or at any building project (new or existing) that intends to install 1 to 6 double 22 kW terminals.
On average, the sales process to a new customer takes 3 months. Implementation takes 6 months, including a declaration of works and a delay before obtaining the batteries. Very few studies are required, it is an almost industrial process.
