TSG and the Fascinating Mission of Being Multi-Energy

TSG is an European group present in thirty countries. Born in the world of traditional fuels, it has evolved into a multi-energy operator, integrating solutions related to electricity, gas, photovoltaics, and hydrogen. The company operates as a technical partner throughout the entire supply chain, from design and construction to the maintenance of energy infrastructure.

Today, TSG is one of the European leaders in technical services for mobility and energy distribution, with a consolidated presence in public transport as well. In 2025, just the local entity TSG Italy managed approximately 60 bus depots equipped with traditional refuelling systems and has installed over 1,760 electric charging points, more than 200 of which are dedicated to Public Transport (PT). “These are joined by several compressed natural gas (CNG) refuelling plants serving fleets of hundreds of buses,” the company explains.

To Be Flexible and Diversified

Indeed, the evolution has been not only technological but also strategic. TSG has chosen to accompany its customers along the transition path, keeping infrastructure management at the core. “We have structured ourselves to support customers in the energy transition, replicating in the field of new energies what we have always done in the oil world. Today, the company integrates several business units into its operating model while maintaining strong continuity with its past. Traditional fuels remain a significant component, especially regarding maintenance and service.”

EPC Contractor for Sustainable Mobility

The TSG model stands out for its integrated approach, which goes beyond the mere supply of technology: “We are able to offer end-to-end solutions. This positioning as an EPC (Engineering, Procurement & Construction) contractor allows us to manage the entire lifecycle of the infrastructure—an increasingly central element in a market characterized by growing technical and operational complexity.”

In fact, the construction of plants is supported by a strong service component, considered the true backbone of the business. This is a particularly relevant aspect in sectors such as public transport, where operational continuity is a critical factor. Added to this is the ability to operate across different technologies in a flexible and “agnostic” manner, integrating various solutions and components based on the customer’s specific needs.

Despite the growing spread of electric mobility, the transition path appears anything but linear. Natural gas – increasingly in the form of biomethane – continues to represent a concrete solution for public and heavy transport.
Looking at hydrogen, H2 represents one of the most discussed technologies, especially for heavy transport and applications requiring high range. “We believe hydrogen can play an important role, particularly for heavy vehicles, thanks to fast refuelling times and high driving ranges.” At the same time, however, the market is still in its early stages. “The required investments are very high, and without strong public support, large-scale deployment will be difficult in the short term.”

To date, TSG is mainly involved in the maintenance of existing plants and participating in tenders for new projects—a sign of growing interest, yet still far from full industrial maturity.
