OFF-GRID I APPLICATION
Q CSP technologies have had a bit of negative press with some suggesting it is now too expensive. Can you
elaborate on whether you feel this has any truth and how your solutions maintain a cost effective approach?
A CSP is definitely more expensive than PV and I believe it will continue to be so. But CSP holds out the promise of
storage that is very expensive with PV using megawatt hour size batteries. So while CSP is more expensive watt for watt, it may be cheaper than PV for a specific application. This is especially true when CSP can function as a hybrid, as in AORA’s technology.
Q What sort of environments do you feel Aora’s products are best suited?
A High DNI, off-grid, village size, needing power 24/7 or close to it. If there is an application for the waste heat,
that improves the economic analysis.
Q How can hybrid technologies help solar become a more accepted power source in the global energy mix?
A Hybridization means flexibility. You cannot be more flexible than a jerry can of gasoline. So being hybrid
brings renewable energy to a higher level of acceptance.
Q Can you please tell us more about the types of alternative fuels that can be used to power the gas turbine?
A It will run on almost any liquid or gaseous fuel with sufficient caloric value to generate the necessary heat.
Q What benefits can a 24 hour operation offer a grid connected installation?
A 24 hour green energy vs. 24 hour coal generated grid power. Clearly, there is less benefit where a grid exists as
explained above. However, for example, there are more than 65,000 villages throughout India without a grid connection, and, in such a vast country, combined they contain almost twice as many people as live in the United States, showing the scale of the challenge.
These people cannot operate refrigerators on a regular basis because they have no power at night. So a woman spends all her time cooking meals for the day, never able to store food and create free me. If there is refrigeration, the wife of the family can work part time outside the home, increasing prosperity etc.
Q AORA states it is committed to finding energy solutions whilst reducing environmental impact. How has the
company achieved this?
A We have gone from considering natural gas as our ideal hybrid fuel to working to perfect a bio-gas based solution.
We will also be beginning a concerted effort to lower the cost of our product and at the same time incorporate as much recycled material as possible to lower our overall environmental footprint.
