Nostromo Energy Limited announced that it submitted preliminary results from a 2-year accelerated stress study to Royal Dutch Shell. The study was funded by and conducted in cooperation with Shell. The results from the study were submitted to Shell and are currently under review. The results of the study suggest that Nostromo's IceBrick(TM) energy storage capsules can withstand 6,600 thermal charge/discharge cycles (equivalent to more than 20 years of use), with a negligible 1% loss in capacity. Nostromo built two experimental energy storage systems to stress-test the capsules over time, under mechanical and thermal cycles. In each of these two systems, a group of 48 IceBrick(TM) capsules were placed (96 capsules in total). In one group of 48 capsules, each cell was subjected to 6,600 full thermal recharge and discharge cycles (freezing and thawing), equivalent to 25 years of use (assuming 260 discharges per calendar year, five times a week). In the second group of 48 capsules, each cell underwent more than 300,000 hydraulic expansion and contraction cycles, simulating the forces acting on the capsules during freezing of water (a 9% expansion in volume). All cycles and pressure data were continuously monitored and documented. Cycles in which the pressure and temperature stress levels were below a minimum predefined threshold were excluded from the analysis. Of the 96 capsules tested, a single failure was detected in the thermal cycling test group after completing 6,100 cycles. Capsules in the second group, which underwent more than 300,000 hydraulic cycles, presented a zero-fail rate. The full report was submitted to Royal Dutch Shell and is currently under review.
