Mr. Alessio Tafone - PhD Student

Short bio

Alessio gained a Master Degree cum laude in Energy and Nuclear Engineering in 2012 at the University of Bologna with a Master Thesis developed at DTU ( Technical University of Denmark) on advanced waste heat recovery organic Rankine cycles.

In 2013 he started working for 6 months at Exergy S.p.a., an Italian company specialized in ORC systems development and production, and then for 2 years at GSE S.p.a.(Gestore dei Servizi Energetici), an Italian public company, that provides financial support to renewable energy source and energy efficiency installations.

In 2016, he joined Nanyang Technological University as PhD candidate at the school of IGS-Erian.



Cooling & Power: decentralized air liquefiers for cryogenic energy storage

The objective of this project is to advance an integrated solution providing both power and cold energy storage. The main driver and focus of this project will be that of working on system level optimization and component design/testing of a small air liquefier (LAES ) to be integrated with a power unit; in parallel it is intended to understand the economics of operating the proposed system in Singapore environment and meeting power and cooling demands.

The LAES draws heavily on established processes from the turbomachinery, power generation and industrial gas sectors. This will provide a shorter product validation period and lower technology risk than most new technologies being introduced in the cleantech and energy storage space.

The project will investigate and demonstrate the opportunity of modular, small-scale liquefaction delivering higher efficiency and lower capital cost as the enabling technology for the mass deployment of LAES (cold and power) at or close to the point of demand. It will allow an integrated “tank of cold” harnessing off-peak and wrong time renewable energy to provide zero emission cold and power for integrated built environment and transport applications as required at the point of demand. This is likely to be suitable for deployment at commercial sites to enable integrated transport and built environment technologies to be deployed; but it is also highly relevant for ‘island’ or remote applications, including bringing tank of cold – and all the applications – to high demand rural locations in emerging markets, or island grids.
