Coal and natural-gas power plants are one of the largest man-made sources of carbon dioxide. But by paying to build a Calera facility next door, a plant can trap that smokestack carbon while producing and selling construction materials. Calera's process combines the CO2 with calcium from underground brine or seawater to produce calcium carbonate, which can act as a cement.
Calera has had a demonstration plant running since 2009 and this year started planning its first commercial facility, which should sequester about 70 percent of the coal plant's CO2 emissions.
Which Should? About? 70%? How much carbon to build and run said system? How long are we going to kill men in mining?
Coal is not and never will be clean.
It's about renewables. Sustainability. Redundancy. Longevity. Invest today and reap rewards long into the future. BUILD IT TO LAST.
You mean renewables subsidized by money borrowed from China, which they generate by burning coal?
This system is a two-for-one special. It sequesters CO2 from fossil fuel combustion and creates cement without burning fossil fuels. It also uses waste heat to run the process. That's three-for-one. Brilliant!
It is only necessary to figure out new ways to keep us quiet! To continue oil consumption, and create a seeming scarcity of energy. Not to mention the trillion dollar car industry that would be hit by a giant reduction in after market value. Where is our money going? and what is money anyways? its oil, that is scarce, not the unlimited source of the sun, waves, etc. Resources are really what our world is made up of, money is just a system of stratification. Look up the Venus Project, the Zeitgeist Movement, Peter Joseph and Jacque Fresco's lectures, really look at it, because I have been trying to refut it, I can't do it. As a member of humanity and nature, i cant stand for it any longer.
It is unfortunate that none of this year's Best of Green Tech includes nuclear energy. It may not be "green" by nature but it could reduce the dependence on fossil fuels and carbons. Notice that many new inventions rely on electricity (hybrid cars, gadgets, batteries, etc). And since hybrid/electric cars are supposed to be the green alternative, we will need greener and more efficient ways to supply the necessary power for the energy grid demand.
