I’m shooting timelapse with a Canon 70D, but one battery only gives me about 4.5 hours of operation, which isn’t long enough for the number of frames I need. Are there official power options or accessories that will let the camera run longer than a standard battery?

Canon (and every other manufacturer) make AC adapters for their cameras. If that's an option, your problem is solved - see Can my Canon Eos camera be used with continuous power? for a bit more detail.

If AC power isn't an option, are you using a grip? These contain a space for an extra battery so should double your available time.

Yes. Camera makers, including Canon, offer AC power adapters for continuous power, which is the best solution if you can plug into mains power.

If you need to stay portable, a battery grip is the usual option. A grip holds an extra battery, effectively giving you about double the runtime compared with a single battery.

So the practical choices are:

AC adapter for continuous power when an outlet is available
Battery grip with two batteries for longer untethered timelapse sessions

For very long timelapses, continuous external power is generally more reliable than relying on a single battery.
