Your partner in creating zero-carbon stations

As a leading provider of both energy and facilities management services, ENGIE is in a unique position to develop comprehensive zero-carbon strategies for train stations, covering energy management, renewable generation, battery storage, facilities management and energy monitoring. Our range of in-house capabilities enables us to provide solutions for all factors that influence carbon emissions, from the way energy is generated to how it is consumed, managed and monitored.

Blueprint for decarbonisation

To support the decarbonisation of train stations, we have devised a zero-carbon blueprint that can be adapted to suit the specific layout, architecture, facilities and functions of stations of all sizes.

There are two core considerations in reducing the carbon footprint of train stations:

1. Energy consumption

We can reduce energy use by introducing energy-efficiency measures and new technologies to manage and control energy consumption. Simple, quick-win measures include installing LED lighting, which gives the same – or better – quality illumination, while using significantly less electricity. We can introduce more energy-efficient equipment, such as boilers or heating, ventilation and air conditioning (HVAC) systems, alongside more intelligent controls to ensure energy is not wasted.

2. Energy sourcing

A key way to decarbonise any station is to look at how the energy it requires is generated, as well as how heating, cooling and hot water can be provided more efficiently. Sourcing electricity from low or zero-carbon sources, such as wind or hydro power is one way to decarbonise. Another is to install renewable or low-carbon energy generation plant on site. Most stations have an abundance of roof space, which is ideal for solar PV arrays. Other on-site electricity generation options include combined heat and power (CHP) plants or wind turbines. Ground-source heat pumps or solar water-heating systems can be installed to supply hot water.

Sustainable self-supply solutions

By considering both energy consumption requirements and energy generation capabilities together, we can devise a solution that matches a station’s demand to its supply capacity, creating a self-supplying system. This can include battery storage assets that enable stations to store the excess electricity they generate during the day for use whenever it’s needed. By retaining the electricity generated on site, batteries enable us to create fully self-contained, zero-carbon stations.

There are a whole host of other decarbonising options we can consider for any station, such as introducing solar-powered electric vehicle charging points in station car parks or extending renewable energy supplies to adjacent depots or local communities. Every station will present different opportunities for carbon reduction, and ENGIE is well placed to assess the possibilities and devise complete, investment-grade proposals for effective decarbonisation.

Long-term optimisation

Beyond the initial planning, implementation and set up, ENGIE can continue to manage the assets on site to optimise energy use and carbon reduction over time. We have the data monitoring and analysis technology to provide all the insights required to ensure decarbonisation measures continue to deliver all projected cost and carbon savings for the long term.
