Exploring Innovative Energy Harvesting: A Comparison of the TRANSLATE and INFERNO Projects

INFERNO, a new waste heat recovery project, led by Dr Kafil M. Razeeb at Tyndall National Institute, has been recently funded by Horizon Europe. Dr Kafil M. Razeeb is also involved in the TRANSLATE project.

INFERNO drew our interest, as similar to the TRANSLATE project, it is driven by the need to harness waste heat, a largely untapped resource, and convert it into usable electricity. While both TRANSLATE and INFERNO focus on converting waste heat into electricity, their approaches are tailored to different temperature ranges and industrial needs.

The TRANSLATE project, led by University College Cork (UCC) is focused on developing nanofluidic technology to convert low-grade waste heat into electricity. Funded by the Horizon 2020 EIC Pathfinder Open pilot program, TRANSLATE leverages breakthroughs in nanochemistry and materials science to address the inefficiencies of existing thermoelectric generators. The project aims to create a device capable of efficiently harvesting and storing waste heat from various sources such as power generators, factories, and domestic heating systems, particularly targeting temperatures below 100 °C.

At the core of TRANSLATE is the development of a nanofluidic device that utilises the Soret effect, which involves ion movement due to temperature gradient. By exploiting this phenomenon within nano-scale channels filled with a salt solution, the project seeks to establish a new energy harvesting platform that is both cost-effective and sustainable. This innovation could potentially power the next generation of wireless sensors and wearable technology, offering a scalable solution for low-temperature waste heat recovery. The project’s emphasis on low-cost, non-toxic materials ensures that the resulting device is both sustainable and scalable, making it a promising advancement in energy harvesting technology.

On the other hand, the INFERNO project, led by Tyndall at UCC, focuses on recovering energy from high-temperature industrial processes. Industries like cement, steel, and glass production lose over 50% of their energy as waste heat, equating to around 400 TWh annually—about one-seventh of Europe’s total electrical power demand.

To address this, INFERNO is developing a novel hybrid system that integrates solid-state devices such as thermophotovoltaic (TPV) cells, photonic metamaterials, and thermoelectric generators (TEGs). This system aims to efficiently recover waste heat from processes operating at temperatures between 400 and 800 °C. The modular design and absence of moving parts make it suitable for retrofitting into existing industrial setups, potentially leading to significant reductions in greenhouse gas emissions.

To summarise the distinction between these two innovative projects, Dr. Kafil M. Razeeb provides insight into their respective focuses:

“In TRANSLATE, we are trying to develop an energy harvesting system based on nanofluidic platform using the Soret effect, which is mainly focusing on harvesting thermal energy near room temperatures. On the other hand, in INFERNO, we are aiming to harvest waste heat that is available in high-temperature industrial processes up to 800 °C by developing a novel hybrid system comprising state-of-the-art TPV, Metasurface, and TEG.”
