Telstra's telecommunication network covers a diverse area, which is subject to Australia's challenging environmental factors. These factors present challenges to the network and can prominently affect Telstra's remote sites, especially off-grid sites. This paper presents the key findings of using stationary fuel cells at these remote sites. The fuel cells implemented by Telstra are indirect methanol and electrolysis-based Proton Exchange Membrane Fuel Cells (PEMFCs). Additionally, this paper covers site logistical challenges and overcoming traditional technology mindsets along with key operational benefits.
