The Green Optimistic

The new technique developed by California-based Simbol Mining could make geothermal wells even more valuable. Extracting lithium with old technologies has up to now been considered impractical.

When we hear about carbon dioxide, it’s like hearing of a serial killer. LBNL (Lawrence Berkeley National Laboratory), and a CA-based company Symyx Technologies, instead, aided by several U.S. universities, have changed the image of this greenhouse gas a bit by putting it into a green job: geothermal energy harvesting.

The group already owns a 17.4 MW plant on a field where it has operating rights since September last year, so this new geothermal field can bring them a total of 77.4MW of power.

Geothermal energy has a lot of potential worldwide. As it is not dependent on many factors, geothermal energy could be the cleanest power source of near future. Two scientists from University of Oviedo, Spain, have concluded that geothermal energy could be provided by mine shafts.

Scientists from the Pacific Northwest National Laboratory in Richland, WA, announce they developed a new type of heat extracting liquid that could absorb much better the heat coming from the hot water in the geothermal wells.

Geothermal technology surely is one of the cleanest technologies available to us, extracting clean heat from the hot underground. This energy source is often seen as inexhaustible, and its benefits seem to outweight its weak points. For decades, geothermal companies have been drilling into Earth’s crust at depths of over 4-5km.

Geothermal energy is considered to be the ultimate energy source in terms of reliability. Since it doesn’t depend on day or night, or other external factor, it is practically undisturbable and has a huge potential.

Paris wants to invest in geothermal energy and already started to dig and drill to reach for underground hot water.

Michael Strizki’s house is the most low impact house I’ve ever seen. He lives his life off-grid, because his home system feature solar panels, 10 hydrogen tanks filled with the excess energy from the solar panels, with the hydrogen taken out of water, and a 15 year-old geothermal system, that covered its price 8 times since it was installed.

Pumping carbon dioxide through hot rocks could simultaneously generate power and mop up the greenhouse gases produced by fossil fuel power stations, according to a new study.
Harnessing geothermal power involves extracting heat from beneath the surface of the Earth. Normally, this means pumping water down through hot rocks and extracting it again. But the new [...]

America can kick its addiction to fossil fuels by drilling more wells, says a panel of experts at the Massachusetts Institute of Technology. Not for oil, but to tap Earth’s heat.
Converting geothermal heat into electricity by pouring water onto hot rocks underground and using the steam to turn turbines is arguably the most promising – [...]
