Yes they resumed testing to demonstrate commercial viability... so far the device had shown stability in over 870 hours operation
“"While the device started to degrade after 105 hours, we are confident that we can fix these issues, resume testing, and ultimately demonstrate commercial viability.” April 9 PR
There should be no confusion. The whole device showed stability in over 870 hours. But before they get to that number the catalyst started to degrade after 105 hours.
The initial goal (Feb 7 PR) was 365 hours but HYSR shoot for 1000 hours because DOE standard for cost efficiency is 1000 hours up. The test had not achieved the DOE requirement but it has achieved an exceeded their goal of 365 hours
