3.3 Steam buffer and condenser buffer.
The RAN-concept includes two types of energy storage. The storage is called Steam buffer and Condenser buffer. The steam buffer is a high temperature storage that will offer several attractive features in automotive applications as well as small scale CHP. The steam buffer makes it possible to design the steam generator for only average power out put. High electric and hot water peak power can be obtained by the steam buffer. The steam buffer smoothing the combustion and enable optimizing of the combustion to avoid environmental harmful emissions. The steam buffer can also be used to store low tariff electricity during nights. The steam buffer unfolds also new possibilities for solar thermal energy applications when it can store the solar energy until occasion when the sun is not shining .The Steam Buffer also makes it possible to matching the mismatch between the electricity and heat demand. Further more Steam Buffer will imply reduced risk for outages when there will be steam available to propel the steam engine even if the burner will break down.
The condenser buffer makes is possibly to condense large amount of steam at a high rate without noise which is important in all kind of applications. For more detailed information see separate document
