How about taking 21.6 million gallons of water per day from the Hakalau aquifer to cool the turbines,
How about injecting the hot contaminated water back into the aquifer via 3 injection wells that are less than 100 feet from the edge of geologically unstable cliffs,
How about the power purchase agreement with Helco to pay 21.5-32 cents per kilowatt for 30 years compared to solar which is only 9-11.
red herring, red herring, red herring...
Where do you think HELCO gets their cooling water from? Thin air? They have major production wells supplying the HELCO power plants, they take it out of the Mauna Loa aquifer and put it back in...
The (HELCO and Hu Honua) injection wells are below the Underground Injection Control Line, which means that, after review by DOH, they are permitted to inject cooling water near the shoreline. Can you show me that the composition of the water from the biomass plant is different from that injected by existing HELCO power plants?
And the cost of that solar is as available - what will it cost to have guaranteed solar PV as base load???
In fact, one of the options being investigated for reducing atmospheric concentrations of CO2 is a process called Bio-Energy-Carbon Capture and Sequestration: where the exhaust gases from biomass combustion are processed to remove CO2 and then that CO2 is injected into the ground. Hawaii turns out to be an excellent place to do that because the injected CO2 reacts with the basalts to form limestone and, hence, the CO2 is sequestered permanently. That is not to say that Hu Honua is planning to use that process - but it would be an excellent place to test the technology.
