Hera and General Electric together for energy recovery

We have installed a turbo expander at the R&M stations of Ducati's factory in Bologna. The goal is to recover electricity from the decompression process of methane gas.

An experimental and innovative project with an ambitious goal: energy recovery and lower consumption of fossil fuels by decompressing the methane gas distributed in urban networks.

The exclusive agreement between Hera Group and General Electric specifically involves installing a turbo expander at the R&M stations (gas delivery points) of the Ducati factory in Bologna. It is a medium-small turbo expander (330 kW electric), which can be installed in medium-sized R&M stations, that in combination with a heat pump that uses CO₂ as a thermal carrier fluid, recovers part of the electric energy to preheat the gas used in the process.

In 2019, we completed all the production start-up activities and started the provisional running phase, in order to carry out all the performance and endurance tests. It is scheduled to start operating at full capacity in the second half of 2020.

Once the testing is completed, if the expected performance is confirmed, this technology can be installed in other methane gas decompression stations of the Hera Group.

The project, moreover, contributes to achieving target 7.3 of the UN’s 2030 Agenda.

A source of clean energy from sewers and wet waste: Biomethane

A revolution rooted in the circular economy: thanks to separate waste collection, organic waste is fed into an anaerobic digestion process to produce biogas.

The connection between the water cycle and agriculture has grown increasingly strong over the years, based on a straightforward principle

Biodiesel has been developed also from used food oil

Fuel may also be extracted from vegetable oils. Used domestic vegetable oil (such as frying oil) which is recovered by multiutility services via roadside containers and drop-off points, is transformed into biodiesel, which in turn is used to fuel the vehicles used for urban waste collection.

Data, the key to a smart future

From city to "smart city" thanks to data: with our detection systems we can monitor traffic trends, air quality and consumption of public parks.

Dialogue with the urban context for new energy: the Borgo Panigale cogeneration plant

District heating is already in itself a "sustainable" and environment-friendly solution, because it can guarantee better performance than traditional domestic boilers. In addition, the plant located in Borgo Panigale ensures lower emissions into the environment, more reliability and greater availability of energy. The system can heat the equivalent of 8,000 residential units. Currently, the turbines can produce 35,000 MWh of energy per year, almost twice as much as in the past.

Ferrara, the city of "green" heat

What's Ferrara's green secret? It lies underground, where a geothermal reservoir powers the city’s district heating system. As a result, 95% of the thermal energy distributed in the city is clean and we avoid about 26,000 tonnes of CO2 emissions per year.
