Narrative:
Upon arriving at the aircraft I performed my walk-around of the aircraft. I noted no irregularities with the exterior of the aircraft. I was the PF. During climbout through 22;000 feet I noticed the EICAS message for hydraulic qty and immediately brought up the status page and noted the right hydraulic quantity was at ~0.28 and falling. We performed the QRH for hydraulic qty. I slowed the aircraft to 270 KIAS to slow our forward progress and we maintained FL230 as last assigned by ATC and we did not climb higher. Next we received the hydraulic primary pump EICAS message. We ran the QRH. Right hydraulic qty was now less than 0.2.we then received the right hydraulic system pressure EICAS message and we ran the QRH. The captain then got on commercial radio and got a patch to dispatch and maintenance. I was out of that conversation as I was monitoring the aircraft and ATC. I later was then told by the captain that we were authorized to return to ZZZ as there were major storms over ZZZ1 and we were so close to ZZZ this would be the safest course of action. I notified ATC of our intention to return to ZZZ. We made a right turn back direct to ZZZ under C autopilot command. None of the QRH procedures said to deviate to the neatest suitable airport. Ultimately; we left hydraulic fluid on [the] runway upon touchdown.

Title: B767-300 flight crew reported a hydraulic system anomaly which resulted in a return to the departure airport.
Narrative: Upon arriving at the aircraft I performed my walk-around of the aircraft. I noted no irregularities with the exterior of the aircraft. I was the PF. During climbout through 22;000 feet I noticed the EICAS message for HYD QTY and immediately brought up the Status page and noted the R HYD quantity was at ~0.28 and falling. We performed the QRH for HYD QTY. I slowed the aircraft to 270 KIAS to slow our forward progress and we maintained FL230 as last assigned by ATC and we did not climb higher. Next we received the HYD PRIMARY PUMP EICAS message. We ran the QRH. R HYD QTY was now less than 0.2.We then received the R HYD SYSTEM PRESSURE EICAS message and we ran the QRH. The captain then got on commercial radio and got a patch to dispatch and maintenance. I was out of that conversation as I was monitoring the aircraft and ATC. I later was then told by the captain that we were authorized to return to ZZZ as there were major storms over ZZZ1 and we were so close to ZZZ this would be the safest course of action.
