Solutions for power generation by pure renewable means. Range 10kW to 30kW, non intermittant.
Looking for solutions, 10 to 30 kW standalone power generation by pure renewable means
Please highlight case studies.
Potential Market
1. Mobile towers
2. Mills, Factories operating power tooling machines, hoists and cranes - Industrials
3. Agriculture - water pumping, deep borewells, Borewell drilling platforms, food processing units
4. Information Technology - Data centers, air conditioning
5. High rise building housing corporate offices - Elevators
Today's solutions -
1. Diesel generator sets. Not so green, noise and air pollution.
2. Use a micro turbine running on biofuel, slightly greener
3. Big Bang migration (uproot) of existing infra (motors and machines) to DC power
4. We have explored Hydrogen. Could not connect with ICE or fuel cell vendors. We feel Fuel cells might not be able to take the load of 10kW - 30 kW. We found fuel cell stack replacement costs very high and operating hours very low.
5. We found biofuels to be expensive.
6. We studied pumped and stored hydro. Present water turbines expect 25-30 liters per second flow pressure. This works out to 360,000 liters for 4 hours and around 720,000 liters for 8 hours. Solar water pumps available here can pump upto maximum of 160 feet only, this limits kW needed to just about 8-9 kW. We will need 6 of them since their daily limit is 125,000 liters only - given good sunlight conditions. Building storage tanks at that height involves considerable real estate, civil works and costs. Not feasible.
We are looking for something better storage solution - batteries are not able to handle this range.
