Headline * *2050 will see 70% of the global population residing in urban areas, fueling a doubling of demand for passenger transport. This, in turn, necessitates more climate-friendly solutions in the transport sector, which still contributes 25% to global CO emissions.

As a global transport leader, our company is championing the development of cutting-edge sustainable technology, moving toward carbon neutrality by 2050.

Milestone Achieved: Adopting Hesop Technology

Hesop, a project aimed at enhancing the energy efficiency of trains in metro, tramway, and suburban DC rail applications, has been introduced to transform braking energy waste into a valuable resource. Our Vice President of Infrastructure and Telecommunications, Ignacio Rodriguez, explains how this innovation works, its sustainability, and regions where it's already being utilized.

The Magic Behind Hesop

When a train brakes, electric motors automatically convert into generators, producing electricity from movement. However, a sizeable portion (15%) of this energy is wasted during regular braking due to non-reversible substations on infrastructure. That's where Hesop comes into play.

Hesop is a reversible substation power converter that's retrofittable or can be integrated into new networks. It consists of three main components: a traction transformer, a reversible converter, and an AC filter. With Hesop, more than 99% of available braking energy can be captured and used to power other traction substations, station facilities, or sold back to energy distributors [3].

Key Takeaways of Hesop

  • Infrastructure Cost Reduction: Hesop allows reduced infrastructure costs by having fewer substations required in new projects. Existing systems can also be upgraded using this technology.
  • Energy Efficiency: Hesop has the unique ability to recover 99% of available braking energy, resulting in lower energy consumption and costs.
  • Operation: Hesop offers line voltage stabilization, facilitates maintenance, and enhances network flexibility to support increased traffic.
  • Environmental Impact: Recovered energy can be used within the network or fed back into the grid, reducing emissions.
  • 123 Hesop units have been sold to 10 networks in 9 countries, including the UK, Italy, Australia, and France [3].

Rapid Transit Networks Currently utilizing Hesop

  • Milan Metro Line 3 has implemented Hesop, thanks to funding from the European Commission's Life+ Programme.
  • London Underground's Victoria Line will feature Hesop as part of a contract awarded to our company by UK Power Networks [3].
  • Athens Metro Line 4 has chosen Hesop for one of the largest infrastructure projects in the EU.

Future Developments for Hesop Technology

our company is currently developing a new smart substation R&D project to further enhance Hesop capabilities. The upcoming smart substation will be able to charge electric vehicles, reuse second-hand batteries, and integrate renewable energy into the grid [3].

Hesop: A Revolutionary Energy-Recovery Solution for Sustainable Rail Transit

Insights:

  • Reversible Energy Storage: Hesop is designed to store excess braking energy and supply it back to assist nearby trains or other systems as necessary [1].
  • Grid Stability: Hesop technology helps stabilize the power supply grid by smoothing out energy demands and reducing peak load [1].
  • Integration with Other Efficiency Measures: Hesop can be combined with other energy-saving technologies like advanced traction systems and regenerative braking to improve overall efficiency [2].
  • By implementing Hesop technology, our company, a global transport leader, aims to revolutionize the transport sector, reducing its carbon footprint by 2050.
  • Hesop's innovative power converter, retrofittable for existing networks or integrated into new ones, recovers over 99% of available braking energy, contributing to significant energy efficiency.
  • With Hesop, infrastructure costs can be reduced, and line voltage stabilization, maintenance facilitation, and network flexibility are enhanced, supporting increased mobility.
  • Already utilized in 10 networks across 9 countries, including Milan Metro Line 3, the London Underground's Victoria Line, and Athens Metro Line 4, Hesop is a testament to sustainable technology's potential in the transport industry.
  • In pursuit of further advancements, our company is currently developing a smart substation R&D project, set to charge electric vehicles, reuse second-hand batteries, and integrate renewable energy into the grid.
  • Beyond train operations, Hesop offers climate-friendly solutions necessary as urban populations surge and global energy demand doubles, enabling the transport sector to progress while minimizing environmental impact.
