The US Department of Energy (DoE) has announced an investment of $2.4m in five projects across the US with an aim of reducing costs and improving efficiency of hydrogen fueling stations.

The projects in California, Illinois, and Connecticut will collect and analyze data from hydrogen fuelling stations besides advanced components and other hydrogen technologies using renewable energy or natural gas.

Analysis of the data in real-world environments will help design improvements to drive further efficiencies.

The investments are part of a two-year initiative and the projects that will receive investment include – one project each of the

California Air Resources Board, California State University and Los Angeles Auxiliary Services, Gas Technology Institute and two projects of the Proton Energy Systems.

DoE will make the funds available in the 2012 fiscal year, with the awardees pitching in with 50% of the project cost.
