An energy storage device includes a plurality of plates, each having a first and second surface, with at least one of the surfaces having a plurality of grooves formed therein. The device further includes inlet and outlet plenums for providing or receiving a heat transfer medium to or from the grooves. At least one of the first surface and the second surface having the plurality of grooves formed therein of a first plate is disposed in direct contact with the other one of the at least first surface and second surface of an adjacent second plate. Heat from the transfer medium is transferred to the plates in a charging mode of operation or transferred from the plates to the transfer medium in a discharging mode of operation when the heat transfer medium is passed along the grooves.

A porous heat exchanger including a single piece core extending axially is provided. The core defines a first air inlet and a first air outlet for a first fluid, a second air inlet and a second air outlet for a second fluid. The first/second fluid flows into the core from the first/second air inlet through a first/second fluid channel and flows out of the core through the first/second air outlet. The core includes solid material sheets and porous material sheets disposed alternately with the solid material sheets so each porous material sheet has an adjacent solid material sheet on each side defining one of the first fluid channel for a flow of the first fluid or the second fluid channel for a flow of the second fluid. Heat transfer occurs between the first fluid in the first fluid channel and the second fluid in the second fluid channel.
