ENERGY STORAGE: LIQUID CH4 AND CO2 NETWORK INTEGRATION

In this project, we will study the energy storage with liquid methane linked to a CO2 network that provides heat for district heating. The generated methane enters an hybrid cycle composed of a solid oxide fuel cell and turbines to generate electricity. Th ...

Breaking Vertical Boundaries. The Spatial Logics and Underground Potential of San Antonio, Texas.

Michael Robert Doyle

For the past century, the urban underground has been developed piece-meal out of necessity rather than as the object of a long-term planning effort. The underground contains not only potential usable space, but also raw materials, groundwater and geotherma ...

Estimating the geothermal potential of heat exchanger anchors on a cut and cover tunnel

Lyesse Laloui, Fabrice Dupray, Thomas Mimouni

This study addresses the geothermal potential of using the anchors of a cut-and-cover tunnel as heat exchangers with the ground for seasonal heat storage. The influence of the soil properties and water table level were investigated. Various service conditi ...
