Siemens Australia, the local arm of the German power engineering giant, has signed on as technology partner for a massive clean energy project that aims to make hydrogen for transport from 5000 megawatts of wind and solar power on the Western Australian coast.

The idea is to build a large scale – up to 5000 MW – solar and wind farm on the 120,000 hectare site capable of producing "renewable hydrogen" energy to be exported to Asian countries like Japan and Korea.
