Biochar

Some paraphrased comments made on the biochar yahoo group relaying our local situtation.

Even though biochar may produce less energy than turning all biomass to ash, it should be pursued since it may have long term benifit in our loam soils.

> We have to stop burning coal!
Our electricity is 98% coal here.

> We have to find another resource for the energy.

> hydrology power
The local source has been tapped. It provides 1%. While we are at the confluence of two rivers damming them for power would flood the region (which would take care of our energy problem). Also a series of locks was put in decades ago so the river is more a seris of lakes as it is that only rarely has large movement (while the rivers
are wide before the locks one could wade acrossed the river except in spring).

> wind
There is little harvestible wind. In fact locally I would be oppossed to wind. We live in one of those valleys that does not get much fresh air. While our modern activities cause pollution even before that time we had an issue with pollen. Mark Twain was quoted as something to the effect that people in Cincinnati were disgusting .. they spit all the time. An effect of the pollen. (He also said "When the end of the world comes, I want to be in Cincinnati because it's always twenty years behind the times.")

> Nuclear power
Bad memories.
I think we have the only nuclear plant that was converted to a coal
plant.

And then there was dear Fernald...

While it is unrelated we have low levels of radon also which is subconsciously attributed to the above two things.

However these nifty mini-generators might be acceptable locally.


> geothermal
The earth crust is extremely thick here and cool to a great depth.
The east coast of the USA will have Geothermal before we do and that is a long way off.

However geo heating of homes works well here. It just needs to be used more. But it more often replaces natural gas and not electric.

> solar electric (photovoltaic)
Also not a real great place for solar but out of all the non-waste alternatives that could be built widely this one would be the leader here. I have hope that some of the newer cheaper flexible solar design that our out will be a good match here. They aren't as efficient as the hard silicon light but they cut in in lower light.

> solar thermal
This works well here. We need to do more of it. Again it replaces more natural gas than coal.

> Conservation
Would you be surprised that this is on TOP of Duke Energy's list?

Also Carsharing may help here as well.

> biomass energy conversion
While we don't have alot of biomass available locally this is my interest in biochar here.


> We could set the price paid for carbon emissions so high that it
drives coal-fired power industry out of business, because it won't compete any longer against the other carbonless forms of energy.

You've hit upon the key as to why I felt the need to start this NKY Carbon thing and my interest in biochar and any solution. Change is coming. Both presidential canditates support cap-and-trade. We have some of the lowest electric rates and we import all of out energy (the coal comes by river, the natural gas and gasoline is
pipelined in)

> [8] As a temporary alternative to coal E&S, biochar from agricultural wastes can be used right now to achieve a net gain in carbon capture and storage, as compared with business as usual, in the course of which these wastes are usually burned. Also denuded forest areas can be replanted. And so on.

> So for existing coal-fired operations for the time being, I would require only a significant reduction in emissions and compensating activities off site for the balance, until we get the technological breakthroughs to make retrofits economically feasible.

Duke is current experimenting with:
- CO2 injection to the saline auqifer
- algea from flue gas
- they want to replace the oldest coal plant with a IGCC system
- their alliance to get biomass burning facilities desinged has been
mentioned in this group
