STEM®-RES is the innovative thermal energy storage technology developed and consolidated by Magaldi in recent years, capable of playing a fundamental role in the global decarbonization process. The growing expansion of renewable and intermittent sources of energy requires a stable supply of energy independent of weather conditions: this is the challenge of our Group.
In this context, STEM®-RES proposes itself as the flexible and low-cost solution capable of storing energy in moments of excess and returning it to those in greatest demand.
A STEM®-RES module is composed by:
The electrical and/or thermal energy, coming from outside the system, is sent into the storage tank containing a fluidized bed of silica sand, inside which the energy is stored, in order to be returned when required.
The benefit of the STEM®-RES technology is summarized in the following distinctive features:
It is therefore the high flexibility and adaptability of STEM®-RES that allows its use in a wide range of applications:
STEM®-RES has been designed with particular attention to the environment using materials that are readily available on the market, fully recyclable, eco-compatible, simple and highly reliable over time. In addition, system components require low maintenance.
STEM®-RES is able to offer electricity, high temperature steam and heat storage providing on demand clean energy for large civil and industrial uses. This energy, thanks to the storage capacity, can also be used in absence of direct radiation, after sunset or during cloudy periods, offering energy availability when required.
The STEM®-RES modules, assembled in a single system, can be managed in series or in parallel, allowing flexible energy generation, reliably and adaptable to the required characteristics. It is possible to add multiple modules in a system, or multiple systems in the same area, to meet a growing energy demand.
STEM®-RES can increase the flexibility of any energy production system, even pre-existing, and optimize its performance through the combination (hybridization) with the surplus of energy deriving from other non-programmable sources present on site (e.g. photovoltaic and wind power).
STEM®-RES is already, in its simplicity, a “disruptive” technology and, thanks to the continuous internal activities of the Research and Development Department in the field of renewable energy innovation, Magaldi is obtaining, testing and validating further important results of the STEM® technology in various sectors and industrial and civil applications.
