Possible these are GNE's Yutongs and that is Voltra's base livery? just hazarding a guess because there's a green front shown in the image
Also the roof pod is different to the E10's/E12's that have arrived already from China for First Leeds and Newport Transport and indicates to me that of a fuel cell bus.
