The SNCF and SNCF Réseau have just entered into a collaboration with the CEA at the INES to develop photovoltaic systems capable of operating at voltages of up to 9000Vdc.
The rail sector has a key role to play in the ecological transition. As it emits much less CO2 than other means of transport, it should experience a new boom.
The European Union, for example, has included in its 2050 transport targets the ambition to
- Ensure that 50% of freight transport over distances of 300 km or more is carried out by rail or waterways, rather than by road;
- Ensure that the majority of medium distance journeys are made by rail;
- Completing the European high-speed rail network.
But the current energy crisis highlights the sector's sensitivity to the price of energy, which for some players can represent up to 20% of their costs.
Among the preferred solutions for strengthening the rail system, stakeholders are considering the implementation of decentralized renewable energy production systems, coupled with battery storage units.
