The first stage of the Angara-5 rocket, capable of delivering up to 25 tons to a low orbit, is powered by RD-191, arguably the world’s best “clean” engine that uses kerosene and oxygen as fuel. "Clean" or more efficient? A liquid hydrogen/liquid oxygen (LH2/LOX) is more "clean" than kerosene and oxygen, as the byproduct of LH2/LOX is water vapor.

More efficient, methinks.

Geptyl used in previous rockets is poisonous.
