Energy Tank

An Energy Tank upgrade in Echoes

The Energy Tank is a common Suit Expansion in the Metroid series, featured in every Metroid game to date. The Energy Tank is used to increase Samus's maximum energy by 100 units (with the exception of Hard Mode in Metroid: Zero Mission, where each Tank increases Energy by 50). They also refill Samus's energy to full upon acquisition. Extra Energy Tanks are represented by small boxes near the top of the HUD. These, like other expansions, are not required to progress through the games' plots, thus creating two challenges: completing the game with all the Energy Tanks acquired, and completing the game with the least amount of Tanks possible acquired.

Locations of Energy Tanks

Metroid: Zero Mission

Location	Items needed	Notes
Brinstar	Morph Ball Morph Ball Bombs	Samus must use her Morph Ball and Morph Ball Bombs to crawl through a tunnel in the ceiling of the room where the first Chozo Statue of the game resides; the Tank is at the end of the tunnel.
Brinstar	No items are needed	Samus must travel to where the second possible Deorem encounter is. At the end of the corridor, the Tank sits on a platform.
Brinstar	Varia Suit	After obtaining the Varia Suit, Samus must travel backwards to a corridor filled with acid, then access a tunnel down under the acid; the Tank resides at the end of the tunnel.
Norfair	No items are needed	After Samus defeats two Kiru Giru larvae, she must jump up to the tank from the corpse of the second larva.
Kraid	No items are needed	After charging up the Zip Lines, Samus must use one on the ceiling nearby to access the Tank sitting on a pillar.
Kraid	Speed Booster	After ending Kraid and obtaining the Speed Booster, Samus must travel to a corridor with several bugs flying around. She must then Shinespark through several blocks that block access to the Tank.
Ridley	Power Grip	While traveling through Ridley's lair, Samus encounters this Tank sitting plainly at the end of the corridor. However, the path to the Tank is lined with fake blocks, so Samus must tread carefully to reach it.
Ridley	No items are needed	After obtaining the third Unknown Item, Samus must jump behind the Chozo Statue holding it; the Tank sits right there.
Ridley	No items are needed	After defeating Ridley, Samus must travel to a corridor with pipes that send out bugs, then lay a Morph Ball Bomb near the entrance of the corridor to access a network of tunnels; the Tank is at the end of the tunnel.
Chozodia	Speed Booster	Samus must travel to the room outside Mecha Ridley's room, then build up enough speed to break through a set of blocks in the room to the left. She will then be able to access the Tank, but only if she succeeds in bypassing tripwire lasers.
Chozodia	Legendary Power Suit Power Bombs	Samus must travel to the glass tunnel that connects the Mothership with the Chozo-built portion of Chozodia, then lay a Power Bomb to break the glass, then exit through the bottom left after laying another Power Bomb to break open the wall. She must then drop down a hole, then travel to the left. Finally, she must Shinespark up through a narrow corridor until she hits the Tank.
Chozodia	Speed Booster	Samus must travel to the room adjacent to the room that holds the Ruins Test, then exit through the bottom right. She must then use her Speed Booster cleverly to keep enough charge through several rooms while traveling to the right, eventually reaching a platform where she must Shinespark to reach the Expansion.

Metroid Prime

Location	Items needed	Notes
Tallon Overworld - Cargo Freight Lift to Deck Gamma	Missile Launcher	When Samus climbs up through the shaft, she must break open the glass at the bottom with a Missile, granting access to the Tank.
Tallon Overworld - Hydro Access Tunnel	Gravity Suit	When Samus travels through the shaft, she must Bomb Jump up to the top of the shaft underwater; the Tank is at the top of the shaft.
Chozo Ruins - Main Plaza	No items are needed	Samus must enter the Main Plaza from the Vault; the Tank is on a ledge by the door she comes out from.
Chozo Ruins - Transport Access North	Missile Launcher	After defeating the Hive Mecha and obtaining the Missile Launcher, Samus must destroy the Missile Door Lock with a Missile to access the Transport Access North; the Tank sits plainly inside.
Chozo Ruins - Furnace	Morph Ball	Samus must roll through a Morph Ball tunnel in the Furnace, accessing a small area holding the Tank.
Chozo Ruins - Hall of the Elders	Ice Beam	Samus must shoot the white-colored lock in the room with her Ice Beam, then enter the Chozo Statue's hands in Morph Ball mode. The statue rolls Samus into a small chamber with the Tank.
Chozo Ruins - Training Chamber	Boost Ball Spider Ball	After defeating the Chozo Ghosts located in the Training Chamber, Samus must use a Half-pipe in conjunction with her Boost Ball to activate a Bomb Slot high up in the room. This activates an elevator that leads up to a set of Spider Ball Tracks that leads to the Tank.
Magmoor Caverns - Transport Tunnel A	Morph Ball Bombs	When Samus rolls through the tunnel to access Phendrana Drifts, she must use a double bomb jump three times to climb up to this Tank high up in the network of tunnels.
Magmoor Caverns - Magmoor Workstation	Wave Beam Thermal Visor	Samus must activate three conduits using the Wave Beam along with the Thermal Visor. After activating the third one, she must roll through to a small chamber; the Tank is inside.
Phendrana Drifts - Ruined Courtyard	Boost Ball Space Jump Boots	Samus must activate two Bomb Slots to restore power to a Spinner, then activate the Spinner using her Boost Ball, thus raising the water level. She must then jump across the ice floes using her Space Jump Boots, accessing a platform with a tunnel she must enter as Morph Ball. The Tank is at the end of the tunnel.
Phendrana Drifts - Research Lab Aether	Missile Launcher	Samus must shoot a containment tank on the ground level with a single Missile, breaching the glass and granting access to the Tank.
Phendrana Drifts - Transport Access	Plasma Beam	Samus must melt a sheet of ice covering the Tank using her Plasma Beam.
Phazon Mines - Ventilation Shaft	Power Bombs	Samus must lay a Power Bomb to destroy a grate in front of a fan, then activate a terminal with her Scan Visor to turn on a fan. This blows a large number of Puffers into another fan, revealing the Tank.
Phazon Mines - Processing Center Access	Plasma Beam	After defeating the Omega Pirate, Samus must exit the Elite Quarters through a Red Door on the upper level of the room. The Tank is in plain sight once she enters the Processing Center Access.
