Swiss Empa scientists and their colleagues have spent four years studying the potential of sodium hydroxide (NaOH) to store heat from the warmth of summer into the cold of winter. The theory behind this kind of heat storage is fairly straightforward: if you pour water into a beaker containing solid or concentrated sodium hydroxide (NaOH), […]

Pacific Northwest National Laboratory (PNNL) using methane, the primary component of natural gas for fuel has designed a new, small-scale solid oxide fuel cell system that achieves up to 57 percent efficiency with room to improve. Fifty seven percent for a solid oxide fuel cell system at this size is significantly higher than the 30 […]
