Great, but UTC Power could not provide information about this low temperature technology.
Besides that: you seem to have a very high flowrate to operate this type of electricity plant. In the Netherland we have the right temperature, but not enough flow. How to solve this challenge?

Higher flow rates are required when using medium to low quality thermal sources for power generation. This is a consequence of the basics of the Carnot Cycle; the lower the temperature difference between the heat source and sink, the higher the flow rate must be between these two points to generate an equivalent amount of power as would be produced from another thermal source that uses a higher thermal gradient. Another way of saying the same thing is to highlight the fact that the lower the temperature gradient, the lower the thermodynamic energy transfer efficiency of the system will be. This flow rate feature that Immanuel mentions can not be avoided.
