Two Australian companies have cracked the ranks of the 2013 Global Cleantech 100, double the number represented on last year’s peer-nominated list which, each year, is whittled down from around 5000 companies worldwide.

CSIRO-developed energy storage start-up Ecoult and Queensland hydrogen fuel cell company Hydrexia both won spots on this year’s index, with Ecoult making the top ten, and Hydrexia taking first place in the list’s Asia Pacific Company of the Year award.

Interestingly, both of the Australian companies to make the list were successful beneficiaries of federal funding via one of the former Labor government’s clean energy investment mechanisms, Australian Renewable Energy Agency (ARENA).

Ecoult was granted $480,000 via ARENA’s Emerging Renewables Program, to go towards testing its world-leading energy storage technology, while Hydrexia received $4.5 million from the Southern Cross Renewable Energy Fund, to go towards its renewable energy storage technology.

As we wrote back in March, Ecoult’s $1.16 million pilot project aims to determine whether its CSIRO-developed Deka UltraBattery technology can lower operating and storage costs for residential and commercial renewable energy systems, through tests on a storage pilot at CSIRO’s Newcastle facilities.

The Sydney-based company is also currently implementing Deka Ultrabattery as part of a full stand-alone Power System for the King Island Renewable Energy Integration Project, being developed by Hydro Tasmania to reduce King Island’s reliance on diesel.
