Hybrid Energy Storage for Underground Mining EV

2021 IEEE International IOT, Electronics and Mechatronics Conference (IEMTRONICS), 2021
One of the main concerns when it comes to contributions to the carbon footprint is the consumption of fuel by vehicles, more specifically that of mining vehicles. One solution to this problem is replacing the combustion engine vehicles with electric vehicles. This also poses the problem of low power density.

Energy Dissipation and Storage in Underground Mining Operations

Rock Mechanics and Rock Engineering, 2018
In this paper, we focus on the energy alteration during longwall mining in an attempt to mimic the conditions of a coal mine in Western Turkey. We verify the proposed model using existing analytical and numerical solutions in terms of stress components.

Underground Storage of CO2 and Energy

2010
Of the known greenhouse gases, political attention to date has primarily focused on carbon dioxide (CO2), whereby it is assumed that underground storages of crude oil and natural gas through Carbon Capture and Storage (CCS) technology could contribute significantly to global climate protection.

Simulation of an underground solar energy storage for a dwelling

Solar Energy, 1991
Abstract The system under study consists of an underground insulated storage beneath a slab floor of an individual dwelling. The storage is charged by solar collectors via two arrays of air ducts buried horizontally in the soil at two depths: 2 m (summer working) and 0.4 m (winter working).

Rock engineering in underground energy storage in Korea

Tunnelling and Underground Space Technology, 2003
Since the early 1970s, Korea has constructed many large-scale underground energy storage caverns in response to rapid industrial development. In this period, rock mechanical engineers in Korea gained valuable experience in developing underground space technologies.

Thermodynamic analysis of an underground sensible energy storage system

Energy Storage, 2019
AbstractElectricity production from concentrated solar power (CSP) plants has been more commonplace in the last decade since the sun is one of the most abundant, renewable energy sources. The heat transfer fluid temperature in a CSP plant may go up to 1000°C; however, most of the current power plants operate on temperature ranges between 220°C and 565 ...

City energy management through underground storage

Tunnelling and Underground Space Technology, 1990
Abstract This paper traces the historical development of the energy infrastructure of cities. As a result of 150 years of this infrastructure mainly comprises electricity, gas, and, sometimes, district heating. This paper describes basic characteristics of underground storage systems applicable within city limits: gas storage, compressed air energy ...
