FluidTech Micro-ORC Technology

FluidTech is in the process of developing an innovative product based on Organic Rankine Cycle (ORC) technology that converts excess heat into more usable forms of energy. This ORC technology is based on a new type of heat exchanger that can generate electricity from a low-temperature heat source. FluidTech has a physical prototype of the technology that has been demonstrated in residential applications. Through a technology development project, FluidTech will adjust, develop, and test the prototype for use in industrial applications.

Challenge

All processes that either use or generate energy have something in common: they generate heat.  Currently, there is no cost-effective solution to recover the heat, so this heat is treated as waste and “thrown away”. FluidTech believes there is a better solution, and that heat recovery can be democratised and used at all levels.

In this project, FluidTech and its partners will develop and optimize a Micro-Organic Rankine Cycle system for low-temperature excess heat recovery. This system is based on a simple and efficient thermodynamic cycle that converts thermodynamic energy into mechanical energy and electrical energy — a “micro power plant” smaller than a refrigerator.

Solution idea

Development of a smaller ORC system that fits in different spaces and can be adjusted for use in different locations. First, a demo model will be developed. The demo model will then be scaled up with a new expander and new liquid, after which it will be tested in a potential application.

Project deliverables

Together with Aalborg University, a prototype will be built, optimised, and tested in laboratories. Subsequently, the system will be tested in a relevant environment in the asphalt industry. These will not simply be experimental tests, since the project will also involve design and optimisiation from a techno-economic standpoint with the aim of offering this technology to the market, rather than merely creating a technological proof of concept.
