DESCRIPTION:Thermomanical energy conversion technologies are poised to pla
 y a leading role in nextgeneration energy systems. Such technologies can 
 be used for the recovery\, re-use and \nconversion of “waste heat”\, w
 hich is widely considered an indispensable element of enhanced industrial 
 efficiency and decarbonisation\, but are also well-suited to large-scale a
 nd long-durationelectricity storage that is essential for grid stability g
 iven the increasing penetration of intermittent \nrenewable generation\, w
 hile improving the affordability of the whole-energy system transition.\nI
 n this talk\, we will present a diverse range of thermomechanical energy t
 echnologies and solutions \nfor the recovery and conversion of waste heat 
 – across temperatures and scales – including heat integration\, ORC te
 chnology\, heat pumps and thermally-driven cooling\, alternative heat-to-p
 ower technologies\, amongst other. We will also review a class of promisin
 g bulk energy storage \ntechnologies based on thermomechanical principles\
 , which includes: compressed-air energy storage\, liquid-air energy storag
 e and pumped-thermal electricity storage.\nFollowing this broad presentati
 on of technological options\, we will explore the underlying operational p
 rinciples in each case\, the resulting performance and cost characteristic
 s\, and \ncompile maps to distinguish the most appropriate options for dif
 ferent sectors and applications. We will address current developments and 
 R&D actions\, technology readiness levels (TRLs)\, costs\, broad brush tec
 hnical and financial characteristics\, advantages and disadvantages\, as w
 ell as \nshare personal knowledge of the challenges faced during the devel
 opment of selected technologies. Finally\, we will attempt to identify rat
 ional routes for the selection of the most \npromising technology(ies) in 
 the specific applications of interest.
