a tray, the tray and a surface of the frame forming a second available volume,
at least some of the first and second available volumes configured to receive components of a hybrid hydrogen fuel cell/battery-based powerplant;
a fuel cell system disposed in at least one of the first available volumes or the second available volume;
a battery system disposed in at least one of the first available volumes or the second available volume; and
a hydrogen storage system (HSS) disposed in at least one of the first available volumes or the second available volume.
2 . The mining haul truck of claim 1 , wherein the plurality of first available volumes includes a front of frame volume at a front portion of the frame.
3 . The mining haul truck of claim 2 , further comprising a cooling system disposed in the front of frame volume.
4 . The mining haul truck of claim 1 , further comprising a cooling system disposed in at least one of the first available volumes.
5 . The mining haul truck of claim 1 , wherein the fuel cell system, the battery system, or the HSS is distributed in: (a) two or more of the first available volumes; or (b) the second available volume and at least one of the first available volumes.
6 . The mining haul truck of claim 5 , wherein the battery system is distributed in two of the plurality of first available volumes.
7 . The mining haul truck of claim 6 , wherein the two of the first available volumes includes a left wheel pocket and a right wheel pocket, and the battery system is distributed in the left wheel pocket and the right wheel pocket.
8 . The mining haul truck of claim 7 , wherein the battery system has a mass, and wherein the mass of the battery system is evenly distributed between the left wheel pocket and the right wheel pocket.
9 . The mining haul truck of claim 1 , wherein the plurality of first available volumes includes an engine bay.
10 . The mining haul truck of claim 9 , wherein the fuel cell system is disposed in the engine bay.
11 . The mining haul truck of claim 1 , wherein the HSS is disposed in the second volume.
12 . The mining haul truck of claim 11 , wherein the HSS is configured to store hydrogen in a gaseous state.
13 . The mining haul truck of claim 11 , wherein the HSS is configured to store hydrogen in a liquid state.
14 . The mining haul truck of claim 11 , wherein the HSS includes a storage tank.
15 . The mining haul truck of claim 11 , wherein the HSS includes a plurality of storage tanks.
16 . The mining haul truck of claim 1 , further comprising a deck having a third available volume,
the fuel cell system disposed in at least one of the first available volumes, the second available volume, or the third available volume;
the battery system disposed in at least one of the first available volumes, the second available volume, or the third available volume; and
the HSS disposed in at least one of the first available volumes, the second available volume, or the third available volume.
17 . The mining haul truck of claim 16 , further comprising an electromechanical replacement disposed in at least one of the first available volumes, the second available volume, or the third available volume.
18 . The mining haul truck of claim 17 , wherein the electromechanical replacement is disposed in the third available volume.
