Solar thermal energy for industry

Basic principles of solar thermal energy

There are 2 main processes to transform solar energy :

Solar photovoltaic energy

Solar radiation is transformed into electricity

Solar thermal energy

Solar radiation is transformed into heat

For its projects newHeat uses solar thermal collectors to transfer solar energy to a fluid: water, steam or thermal oil.

Non-concentrated technologies produce temperature up to 120 °C

newHeat taylors the different solar thermal technologies for its client’s projects. Completely independent from its suppliers, newHeat works exclusively with world class manufacturers.

INTEGRATION OF SOLAR THERMAL ENERGY IN THE INDUSTRIAL PROCESS

Exemple d’intégration de type “fuel saving”

The existing conventional boiler will be kept in most cases. Especially during less favourable periods (winter, clouds), it will compensate the lower solar heat supply in order to ensure process continuity. This model, detailed in the schematic below, is called « fuel saving ».

The thermal energy produced by the solar thermal collectors is pumped through a hydraulic system and transferred to the client’s heat network via a heat exchanger.
newHeat’s expertise lies in the selection of the best integration point and the design of the heat exchange system. This ensures that process reliability for newHeat’s clients is maintained.
In order to make up for the inherently intermittent nature of solar energy and ensure heat supply remains within process specifications (temperature, pressure, fixed or adjustable flow rates) newHeat designs bespoke production management systems for each project. The production management system regulates, stores and transfers solar heat output in order to optimize delivery to the client’s process.

With its unique know how, newHeat implements a production management system that maximizes solar thermal energy production and prevents any interruption in the heat supply to the process.
