Alternative Energy / Geothermal Energy

  • Shell Backs Geothermal Gun Tech

    From compact fusion to solar energy generation, the world has been desperately searching to find a way to generate energy which is not only abundant but cleaner and cheaper than conventional fossil fuels. Geothermal energy is one energy source which is more than capable of satisfying the world’s entire energy needs (at least in theory). Apart from being the cheapest renewable source, geothermal energy scores over wind and solar power when the issue of intermittent power generation arises. In spite of its benefits, its global installed capacity when compared to solar and wind power is miniscule. However, geothermal energy is…

  • Benefits Of Geothermal Power Outweigh The Risks

    The debate over geothermal energy has generally been a quiet one. With just 13 gigawatts (GW) of global installed capacity, it is considered by some to be a relatively non-controversial (or even irrelevant) energy issue. Yet a new study questioning the health risks associated with geothermal power generation could bring this neglected energy source into the spotlight. Brushing the usual fear-mongering headlines aside, the study raises an important question – what are the risks associated with geothermal power? The study itself is careful not to equate correlation with causation. The authors suggest that exposure to hydrogen sulfide (H2S) emanating from…

  • What Is Really Keeping Geothermal Power Back?

    Earlier this month an article published on Oilprice argued that the future for geothermal power was limited, at best. In short, the article argued; • There are a shortage of high-temperature resources; • Geothermal heat can’t be transported and must be used on site; and,• Questioned geothermal power sustainability. However, these three points have little to do with geothermal power’s barriers to growth for the following reasons; • When including temperatures as low as 95?C the resource base vastly expands. With Organic Rankine Cycle technology, geothermal brine can produce electricity at temperatures less than that of boiling water. The geothermal…

  • Why Geothermal Energy Will Remain A Small Player

    Geothermal is presently a minor player in the field of renewable energy and for the reasons discussed here is likely to remain one, but Energy Matters has never featured it before and it deserves its fifteen minutes of fame. Besides, I worked in geothermal a number of years ago and haven’t revisited it since, so it’s time I updated myself on what’s been going on. I start with a bit of personal memorabilia. Below is an aerial view of the Hudson Ranch 1 plant in the Salton Sea geothermal field, California, a three-stage flash plant with an installed capacity of…

  • Geothermal Power Gathering Steam in U.S.

    The bubbling sulfur springs and powerful, majestic geysers of Yellowstone National Park are visible manifestations of the potential for geothermal energy in the United States. Yet for various reasons -- including logistics, economics and permitting issues -- geothermal has not even come close to reaching its potential. That could be changing, though, with the introduction this summer of a series of geothermal bills that may hasten its development and remove some bureaucratic obstacles. Renewable Energy World reported at the end of July that U.S. House and Senate subcommittees discussed permitting needs and took up two bills related to geothermal development.The…

  • Drilling Down To The Economic Realities Of Geothermal Power

    When someone who has just completed a series of mining asset sales totalling $1.6 billion chooses to share some frank thoughts on geothermal power, you have to respect the source.Geothermal bubbled up in the news in May as a lost opportunity for BC Hydro in the Joint Review Panel's thumbs-sideways assessment of the Site C dam project.Lumina Copper founder Ross Beaty knows something about copper – enough to complete the company's sale to First Quantum Minerals earlier this month for $470 million. Beaty is also passionate about renewable energy, which led him into a geothermal power investment in 2008, only…

  • Geothermal Gains Traction in Post-Fukushima Japan

    Japan’s Chuo Electric Power Co. is preparing to launch the country’s first new geothermal power project in 15 years at a time when Tokyo is grappling with energy alternatives to its deactivated nuclear reactors. The new geothermal plant on Japan’s southern island of Kyushu will take advantage of the area’s natural hot springs and volcanic activity and will be one of the first to go online since 1999, boosting the nation’s geothermal power-generation potential which currently represents only 2%. Chuo Electric has said it plans to open five more geothermal power-generation plants in the next five years. Related Article: Three…

  • Japan Looks at Dozens of New Geothermal Power Plants

    In the aftermath of the 11 March 2011 Fukushima Daiichi nuclear crisis, the then ruling Democratic Party of Japan took all of the country's 54 nuclear reactors offline before subsequently restarting two NPP reactors at the Oi nuclear power facility in Fukui Prefecture.Nevertheless, not unexpectedly, resistance to nuclear power generation nearly three years after the Fukushima Daiichi debacle, which shut down six reactors, remains quite substantial.  Accordingly, seeking alternative power sources has increased, with the result that construction plans for mid-sized geothermal plants is becoming a boom energy concern across Japan in the wake of the 2011 “Great East Japan…

  • Iceland Taps Magma for 24/7 Geothermal Energy Source

    Renewable energy has always faced a significant bottleneck for broader acceptance – the wind doesn’t blow 24 hours a day, the sun doesn’t always shine, and 24/7 renewable power sources such as hydroelectric dams require massive investment before coming operational. Given that consumers are solely concerned with bottom line, the cost of a kilowatt-hour, renewables have faced an uphill struggle to gain acceptance.One 24/7 potential source of renewable energy is geothermal, and now Iceland has apparently surmounted one of the industry’s bottlenecks...and it was inadvertent.Iceland’s first “magma-enhanced” geothermal Icelandic Deep Drilling Project IDDP-1 well at Krafla has been proclaimed successful,…

  • Hawaii Embraces Geothermal – Cautiously

    In the ongoing energy debate about fossil fuels versus renewables, solar and wind renewable sources have a shortcoming – the sun doesn’t always shine, the wind doesn’t always blow.Three renewable resources, in contrast, can provide electricity 24/7 – hydroelectric, wave and geothermal. A major plus side for all three is that, like nuclear power, they emit zero greenhouse gases.While geothermal use is still a fraction of wind and solar, it is drawing increasing interest in the year of its centenary, when the world’s first commercial geothermal power plant opened in 1913 in Larderello in the Tuscany region of northwestern Italy,…
