During initial operations at Dudingen, a number of upgrade possibilities were discovered to improve the durability and performance of the system. These upgrades are now complete and our datasheet has now been revised to reflect the better performance:

The new performance was better than we hoped for and demonstrated 85kW of electricity equating to over 16% efficiency based on electricity out / calorific value of fuel consumed. Over the coming weeks we plan to gradually increase furnace temperatures to achieve 100kWe output.
