Pietro Fiorentini’s complete power-to-gas solutions

80 years of experience in processing natural gas combined with our commitment to the process of decarbonisation has driven us to develop complete power-to-gas solutions. From pure hydrogen injection systems after blending to the development of hydrogen-ready network solutions, we are contributing to the development of the infrastructure to overcome the technological constraints that limit the introduction of green gases.

Apart from power-to-methane solutions, which balance out this effort, making the green gas produced fully compatible with the relevant infrastructure from the outset, Pietro Fiorentini has recently expanded its service offerings to alternative biological methanation systems designed to meet renewable energy production needs in small to medium-sized plants.

Biomethanation systems

In the biomethanation process, billions of methanogenic microorganisms called Archaea metabolise hydrogen and carbon dioxide into methane and water within an anaerobic environment.

This process is particularly appropriate where strong reactivity is required, such as with power-to-gas, and in cases where contaminant-laced gases are processed with traditional technologies that would require pre-treatment to avoid catalyst poisoning.

Biomethanation also allows us to exploit the synergies between power-to-gas and biogas anaerobic digestion plants as the sludge present can be used as nourishment for the Archaea.

These are innovative solutions that reinforce Pietro Fiorentini’s commitment to the production of green molecules: our biogas-to-biomethane upgrading systems, decentralised grid gas injection solutions and BiRemi™ have already set in motion and continue to support the modernisation of the infrastructure designed around the transport and distribution needs of green gas.

2. Pietro Fiorentini’s commitment to energy transition

Power-to-gas is now one of the most promising technologies for facilitating the energy transition and complying with the Green Deal that was signed by the European Union, which envisages zero net greenhouse gas emissions by 2050, with extremely challenging intermediate targets for 2030.

In fact, utilising existing gas infrastructure will make it possible to make large quantities of energy widely available. A journey towards decarbonised and defossilised gas systems embedded within energy infrastructures that will be holistic, according to Pietro Fiorentini’s vision. Thus, it will not only include gas treatment plants and technologies, but projects capable of encompassing all the solutions needed to achieve system resilience within a single environment and meet the new requirements of balancing energy supply and demand.


Managing 'green electrons' over time and space is important to obtain as much energy as possible when renewable sources such as the sun and the wind are available. Power-to-gas, a technology that transforms surplus electricity into gas molecules that can be transported over long distances at low cost and can offer the possibility to seasonally store renewable energy, is the answer.
From electricity to green gas

Power-to-gas technology exploits the phenomenon of electrolysis: excess renewable electric energy from wind farms, photovoltaic fields and electrical infrastructure congestion is used to break the bonds of the water molecules and produce hydrogen, which can be upgraded on site or transported to other places.
