Issue description:

The Energy Upgrade no longer reduces the operating power costs for the Electrolytic Separator, it only increases the internal power reserves that the machine has available.

Steps to reproduce:

1. Place down Electrolytic Separator, wire it with power and pipe water into it.
2. Watch and note operating power cost.
3. Put a full stack of 8 Energy Upgrades into it, then go back to power panel on the machine and watch as the operating power cost for the machine does NOT decrease.

Not so much a bug as a balancing thing. Making hydrogen then burning hydrogen used to be a net gain from what I understand.

So having the Electrolytic Separator's operating power cost increase when you increase HydrogenEnergyDensity is intentional as well? In it's present state, having Hydrogen even available as a fuel is 100% pointless. The whole setup always results in a zero-sum setup... power generated is power consumed.

Why even have it as a fuel?

A good question, one to which I don't have an answer sorry.

They've never been meant to reduce usage in the separator, as doing so would allow for a net energy gain, thus violating thermodynamics.
