I keep getting more questions on our Microgrid module. One question is how does a small Microgrid solar array with cement storage and ORC engine compare to Concentrated Solar Power (CSP) installations. See my previous blogs on what such a system is like and its economics.

Some of you have asked about our Microgrid module and how it could be used to power a microgrid. Here’s the details. I envision the smallest microgrid plant to produce 100kW of electrical power. Larger plants would use multiples of 100 kW, for example a one MW plant would be made of ten 100 kW plants. This is on the small size for current turbogenerators because efficiency drops quickly if they are even smaller. A 100 kW plant can power 20 US homes at 5 kW per home. My earlier blog (Apr. 14, 2015) showed a preliminary design for a Microgrid module system with concrete cylinder storage. What capital costs ($/W) could be expected for a complete system (collectors, storage and ORC engine) if it were produced in China? What will be the cost of energy over the plant's lifetime? |
