What is Geothermal Energy?
To put it simply, it’s the heat beneath our feet. Did you know that at its core, the earth is roughly as hot as the surface of the sun? About 4,000 miles down, the earth’s molten core is over 6,000°C (or 10,800°F). That heat isn’t disappearing anytime soon – thanks to the continuous decay of naturally occurring radioactive elements which generate roughly 30 ...

Strada Global: Why we need to rethink the map on Geothermal
For decades, everything we’ve known about geothermal potential has been modelled on a map that shows available resources in some parts of the world, but not others. We need to change that mindset and make people aware that we’re standing on vast resources of geothermal heat, wherever we are in the world. When it comes to geothermal, there are hurdles in people’s minds. They ...

Developing Sustainable Geothermal Technology
Developing and implementing innovative technology is about far more than just the big idea. Ensuring that a venture fully capitalises on its opportunities and prototypes is more like a journey that involves a team with a vision, backers who understand the value of that vision and a relentless pursuit of potential. For Strada, it’s about accelerating the opportunities our ...

Changing The Mindset On Geothermal
‘Geothermal energy is potentially the largest – and presently the most misunderstood source of energy in the US and the world today’ Al Gore So why don’t we use more of it? After all, geothermal energy has practically unlimited potential and could theoretically power our entire planet. Yet only a tiny fraction is being used. The challenge is tapping into it in a ...

Unlocking The Potential of Geothermal Could Provide All The Energy The World Will Ever Need
One of the biggest challenges facing mankind today is our quest to transition to renewable energy. We need a stable, constant energy source that doesn’t harm our planet. Geothermal energy generation is clean, renewable and cost-effective over the long term, and the world has vast, untapped geothermal resources. So why is it still operating on the sidelines? Compared to other ...

Projects Thermoelectric Generators in a Geothermal Field - Case Study
This is an R&D project which will build and test a new field-scale thermoelectric generator (TEG) at our Bottle Rock Power geothermal facility near Cobb, California. TEGs produce electrical energy when a strong enough temperature difference exists across the generator (a phenomenon known as the Seebeck effect). This will be the first TEG developed specifically to generate electricity from a ...

Projects Newberry EGS Demonstration, Oregon - Case Study
The Newberry EGS Demonstration project is the site of cutting-edge research into enhanced geothermal systems (EGS) development. AltaRock Energy began investigating the Newberry site for EGS development in 2009 . The project site is located on the western flank of Newberry Volcano in Central Oregon and aims to improve the feasibility and viability of EGS technologies and applications. The major ...

As Global Demand for Electricity Grows, Geothermal Energy Heats Up
January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of catastrophic ...

Case Study - Aluto Langano Power Plant Rehabilitation
Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

Renewable Energy - A Key Solution to End Global Warming
Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...

Design of method and mechanism for geothermal energy extraction
By drilling using a specially designed hydride carbide (melting point: 1,365°C) drill, we can drill the earth's crust to about 5 to 40 km to reach temperatures of 700 to 1,000°C, with minimum cost of the drill and drilling technology. Further, we can extract energy by pouring in water on an inserted carbide alloy vessel into the drilled well and bringing out as steam to drive the turbines. By ...
