Cryogenics in Renewable Energy Storage: A Review of Technologies

Energies, Journal Year: 2025, Volume and Issue: 18(6), P. 1543 - 1543

Published: March 20, 2025

The increase in the exploration of renewable energy sources intensifies need for efficient storage solutions to mitigate inherent intermittence these sources. Among available technologies, cryogenic (CES) systems stand out as a major and promising technology due their high scalability, efficiency, potential integration with other systems. This paper deals approaches, focused on Liquid Air Energy Storage (LAES). Several topics are addressed, including characterization CES systems, working principle, special relevance efficiency temperature/entropy diagram, conception technical challenges, design, construction CES. LAES demonstrates efficiencies ranging from 45% 70%, potentially reaching up 75% complementary capital costs 900 EUR/kW 1750/EUR/kW. Carbon dioxide (CO2)-based while more energy-efficient (40% 60%), face significant barriers infrastructure costs. Additionally, hybrid configurations that combine advanced thermal cycles waste heat management achieve between 55% 80%, showing adaptability complex scenarios. In comparison alternatives such batteries Compressed (CAES), despite economic technological limitations, have role global transition, particularly anticipated advancements will enhance competitiveness viability.

Deformation Monitoring Systems for Hydroturbine Head-Cover Fastening Bolts in Hydroelectric Power Plants

Sensors, Journal Year: 2025, Volume and Issue: 25(8), P. 2548 - 2548

Published: April 17, 2025

This study investigates the reliability of Francis turbines and highlights critical need for an improved deformation monitoring system bolts that fasten a hydroturbine head-cover to its casing. During different operational stages hydraulic unit, such as start-up, partial load, full fastening are subjected static cyclic loads. The loads generate vibrations deformations must be monitored. Although various measuring instruments, vibration sensors accelerometers, have been developed monitor vibrations, only two systems—KM-Delta-8-CM PTK KM-Delta—are currently applied measure bolt deformation. Furthermore, one system, SKDS-SISH, was found forces inducing this After analysis, it is evident described systems do not guarantee trustworthiness there their improvement. implementation self-checking function (including metrological features), development digital twin sensor, application technologies based on artificial intelligence could solve problem.
