Some of that ARPA-E funding has gone to wind turbines, electric-vehicle battery research, solar power systems, and even geothermal energy projects, among many others. This week, […]

What's most interesting about his discovery is that the three metals form a very light alloy, about 40% lighter than a Lithium Ion battery pack at the same size (for example, a Prius battery weights 317 kg, while this hydrogen tank would only weight 200 kg).
