Puna geothermal plant
#1
Just wondering what the skinny is about the Puna geothermal plant - I've seen a few references to it in the postings, but I'm not clear. Is it noisy, smelly, what? From western Leilani I seem to remember hearing a deep noise that I didn't know what it was - the plant?

I also think I read that that one plant provides 20% of BI electricity - if that's corrrect, then making the BI totally carbon neutral, as far as electricity/etc is concerned, should be easy.

Mmmm. You certainly wouldn't be the first to fantasize about that scenario, olin137.
However, I'm afraid you'd just be opening a can of (very hot) worms.

See, the initial plans actually did call for dozens of wells to be drilled, but protests in the late 80's to mid 90's pretty much put an end to all that.

There were health concerns. There were noise concerns. There were concerns regarding future/additional blowouts. And naturally there were serious concerns as to where the drilling fields would be located.

Heaps of concerned citizens managed to protect not only their neighborhood, but the Wao Kele o Puna Rainforest.

I think with prices of energy constantly on the rise here in Hawaii. That sooner or later we will have to visit Geothermal energy once again and consider our options.
In a perfect world Geothermal Energy is clean energy ,and one that residents of Hawaii could benefit from.

At some point in time higher electrical bills will force Big Island residents to consider Geothermal options once again..

H2S is one of the most dangerous gases. I work as a Cargo Surveyor loading large ocean going tankers with crude oil. One of the dangers is H2S emmitting from the crude. We have learned through safety training that constant exposure to H2S will deminish ones ability to acutally smell the gas. So, the danger is obvious. Once we have been overexposed we will not be able to detect the odor with our sense of smell. We can still smell other things, but not the H2S. This stuff is nasty.

I sincerely hope you're wrong about that Beachboy. Would much prefer that folks pursue the truly-clean, more-reliable, non-dangerous, options out there.....like the wind, the sun, and the waves.

I think Pele would agree.

sure those are all great options. But what seems to be the problem with implementing these natural resources, cost or apathy? If apathy is the sole problem I hope we don't wait until it's to late to make these necessary changes? Though Solar seems to be an expensive option if you go through Helco to get set up.

I just don't trust the company to be watching out for the lives of everyone downwind from the plant.

In the independent investigation of the blowout that I linked above, it says:

"This report finds that the blowout occurred because of inadequacies in PGVs drilling plan and procedures and not as a result of unusual or unmanageable subsurface geologic or hydrologic conditions. While the geothermal resource in the area being drilled is relatively hot, the temperatures are not excessive for modem technology and methods to control. Fluid pressures encountered are also manageable if proper procedures are followed and the appropriate equipment is utilized.

A previous blowout of short duration occurred on February 21, 1991, at the KS-7 injection well being drilled by PGV at a depth of approximately 1600'. This unexpected incident alerted PGV to the possibility of encountering a high temperature, fractured zone at a relatively shallow depth. The experience at KS-7 prompted PGV to refine its hydrological model; however, the drilling plan utilized for KS-8 was not changed.

Not only did PGV fail to modify its drilling program following the KS-7 blowout, but they also failed to heed numerous ''red flags'' (warning signals) in the five days preceding the KS-8 blowout"

Also, if you look at the EPA's review of Hawai`i County's emergency response plan, the EPA did not think it was up to snuff and commented that PGV's communication lines with first responders weren't that great.

Guess I don't like having a facility "next door" that makes it necessary to have an evacuation plan for the entire region.

Another one of Daniel Inouye's pet projects ... he wanted an undersea pipeline to take the energy produced here to serve Oahu (and Maui) -- not to make the Big Island self-sustaining.

If you read just one of the links I provided, take a look at this article about the politics around this project, the people with health problems that are being pooh-poohed, and the fact that this plant has had a major incident (and Harry Kim feels deeply apologetic to the people about how it was handled).

http://www.chron.com/content/chronicle/n...awaii.html

To sum up the response to people's health concerns:
1) the effects of hydrogen sulfide exposure are known

2) the Puna citizens who complained were rabidly anti PVG

3) therefore, they have studied the symptoms they would have from hydrogen sulfide exposure and are reporting them even though they don't have them.

4) therefore, complaints about health issues can be ascribed to a bunch of radicals and may be dismissed.

I find it interesting when HELCO is using renewable your electric bill does NOT go down. They charge the same as they do when using diesel, bunker etc.

The windmills at Southpoint is blowing so strong and making so much electricity that the old electric lines cannot keep up that HELCO has had to reduce the electricity it is producing. Wouldn’t one think they would put in bigger lines that can accommodate the electricity produced and start eliminating the use of fossil fuel? Oh and also start reducing the cost of electricity.

I think some differtiation must be made from the original PG owners to the new owners which happened I think in early 2000-2002 sometime. Some one correct me (I know you will ha ha ) but the new owners put a lot of cash into bringing PGV into safety compliance, etc. I thought they bought PG at fire sale pricing and then had the money to invest in equipment.

(This is not an opinion on if it is good or bad - just trying to determine the two different periods & levels of saftey.)
