The future's thermal battery

PCM thermal battery

The i-TES thermal storage tank

i-TES develops and perfects thermal storage systems using phase change materials.

These are innovative batteries made with bio-based materials, thanks to which it is possible to improve energy efficiency by reducing waste in thermal uses.

i-TES batteries work well in combination with a wide range of systems, bringing together the different forms of heat generation – all of which contribute to defining them as the batteries of the future.

A future that is already a reality, thanks to i-TES.
Discover our case history


i-TES thermal batteries contain PCM materials of biological origin.


Small size

i-TES thermal batteries take up about 50% less space than traditional storage forms.



Thermoregulation and temperature stability are among the main features of i-TES thermal batteries.



Thanks to thermal batteries, energy uses are independent of production sources.



The thermal batteries of i-TES are easily integrated in new design systems, but also in existing ones.



i-TES thermal batteries are scalable energy efficiency solutions.



i-TES thermal batteries use materials that are safe for health and the environment and have no moving parts.


Easy maintenance

i-TES thermal batteries are static objects with a long-life cycle.

The role of the PCMs

i-TES has chosen to put at the center of its technology 100% natural materials.
These are the PCM, or phase change materials, materials capable of revolutionizing the way we make energy efficiency.

The transition 5.0

The fifth industrial revolution is underway. The three pillars on which it is based (humanocentricity, sustainability and resilience) have been outlined by the European Commission and aim at an industrial advance that integrates social and environmental aspects in addition to technological progress.

This process requires companies to adopt a circular economy approach and improve the adaptability of production processes, placing society and sustainability at the center.

This means that, with Industry 5.0, enterprises will have to adopt innovative technologies and review their business models. The focus on respect for people and the planet becomes increasingly crucial, with an expectation of adaptation to the principles of ESG (Environmental, Social, and Governance) by the entrepreneurial fabric.

In this context, the Minister of Enterprise and Made in Italy, Adolfo Urso, announced that 12 billion euros will be allocated in 2024-2025 to Transition 5.0, with the aim of supporting companies in the ecological and digital transition. These funds, part of the National Recovery and Resilience Plan and the Repower-Eu tool, confirm the government’s commitment to a significant shift towards more sustainable and technologically advanced business practices.
