What is thermochemical energy storage (TCES)?

Thermochemical energy storage (TCES) has attracted significant attention in recent years due to some unique features of the technology such as very high energy density and negligible heat loss during storage. The TCES, however, is still at its early stage of development currently at a technology readiness level of 1–3.

Are hydrogen induced failures a major integrity problem for steel pipes?

At pressure levels in the natural gas distribution network in Europe, hydrogen-induced failures are considered as major integrity problems for steel pipes. Recent attention has been paid to hydrogen embrittlement of APL 5L X52 pipe steel in the service conditions.

What is the thermal efficiency of charge and discharge reaction?

The thermal efficiency of the charge and discharge reaction can reach 85.2% and 94.5%, respectively. However, serious short-circuit will occur in the airflow of both reactors. A large number of granular materials can only contact water vapor through the diffusion of water vapor in the air, thus prolonging the heating and releasing time.

Which flow is best for a fully charging and discharging reactor?

The heat release rate of the parallel flow was faster, and the full heat release of the material in the reactor could be achieved in a shorter time. Therefore, for a fully charging and discharging reactor, no matter how the operating conditions change, the air–water parallel flow has the best promotion on the discharging effect. 4.4. Discussion

Does API 5L X52 pipeline steel reduce elongation after hydrogen absorption?

In this study, we have used the API 5L X52 pipeline steel given by Elazzizi et al. . After hydrogen absorption, a small decrease in the yield stress has been noted (2.5%) as an important reduction of elongation at failure of 38%.
