“…Salt caverns can achieve a recovery efficiency of 100%. 50 This results in a higher need for compressors for salt cavern sites, resulting in higher capital costs (Figure 3C). The higher cycling rate results in a higher annual WGE, decreasing the levelized costs of salt caverns.…”

The mass storage of hydrogen is a challenge considering large industrial applications and continuous distribution, e.g., for domestic use as a future energy carrier that respects the environment. For a long time, molecular hydrogen was stored and distributed, either as a gas (pressurized up to 75 MPa) or as a cryogenic liquid (20.4 K). Furthermore, the atomic storage of hydrogen in the solid-state form via metallic or covalent compounds is still the subject of intense research and limited to a small scale for some practical developments. In addition, other type H chemical storage routes are being tested, such as ammonia and LOHC (Liquid Organic Hydrogen Carrier), etc. In any case, the main constraint remains security. However, Hydrogen Solid State Storage (HSSS) using MgH2 bodies has been shown to be feasible in terms of process and safety. Furthermore, its intrinsic volumetric densification was proven to be much better performing with 106:70:45 kgH2/m3 for solid (RT):LH (20.4 K):gas (75 MPa), respectively. Very early on, fairly reactive MgH2-based pellets were produced (for max. ~27 tons/year) at McPhy Energy using a series of unique and self-built installations. Thus, the design of large instrumented reservoirs was undertaken thanks to fundamental research first carried out at the CNRS. So, prototypes of storage units from 100 to ~5500 kWh have been produced. However, McPhy took other routes a few years ago (smelting and refueling stations) because the HSSS market was not merging at that time. Today, a new operator, Jomi–Leman, therefore, decided to try the challenge again focusing on applications with on-site production and mass HSSS.

“…As one of the five major transportation modes, pipeline transportation has the advantages of low loss, strong continuity, smooth operation, convenient management, safety and reliability, etc. 1 Nearly 100% of the world's natural gas and more than 85% of oil are transported through long-distance pipelines. 2 With population growth and economic development, energy demand continues to increase, and pipeline construction has been developing rapidly.…”

As the total mileage of the pipeline and the years of operation are increasing, the threat of landslide and corrosion defects to the safety of pipeline operation is also increasing. In this paper, based on the nonlinear elastoplastic theory, a pipe-soil coupling model is established to determine the maximum stress location of the pipeline containing corrosion defects under the action of landslide, on the basis of this location, the internal pressure of pipeline operation and the factors such as landslide width and landslide displacement are analyzed. Through multivariate linear regression, the equation of the maximum stress of the pipeline with the change of landslide width and displacement is fitted. The results show that in the landslide area, the operating pressure has less influence on the safety of the pipeline and the existence of corrosion defects will lead to sudden stress changes here, which will lead to the perforation of the pipeline; with the increase of the landslide width and landslide displacement, the plastic deformation area will appear in the middle of the pipeline, which means that the pipeline in this area is prone to bending, rupture and flattening and other failures, and the safety of the pipeline has a greater risk. In the non-slippery area, the maximum stress of the pipeline will increase with the increase of operating pressure, landslide width, and landslide displacement. Through multiple linear regression, the correlation coefficients of fitting the maximum stress of the pipeline with the expressions of landslide width and displacement are 0.959 and 0.996 respectively to prove the reliability of the formula.
