Strada Global: Why We Developed Our Geothermal Technology
I was interviewed recently by Patrick Hanson of Geo Energy Marketing, an organisation in the US that seeks to tell the stories of innovative businesses within the geothermal space. Read the interview below for a closer insight into why Strada chose to focus on geothermal technology, the mission that drives our company and why we believe geothermal innovation can be the solution to the ...

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 ...

Cultivating geothermal energy sources – Case Study
Since the early twentieth century, geothermal energy has been used to produce electricity. In the 1980’s and 90’s, rapid expansion in the demand for geothermal energy put pressure on suppliers to reduce costs and increase efficiencies. Because of high temperatures and varying pressures, measuring steam flow through "Differential Pressure" methods was fraught with inconsistencies. ...

Powering up Geothermal
As a drilling technology company, it’s been interesting here at Strada Global to see the focus on geothermal energy gathering pace. The Net Zero commitment to decarbonise economies means that we’re seeing accelerating interest in geothermal energy from governments. Recent media coverage has reflected this, including the World Economic Forum’s article ‘Geothermal energy, ...

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 ...

Geothermal Power Approaches 12,000 Megawatts Worldwide
In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal’s best year since the ...

What’s geothermal again?
Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

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 Davenport Newberry Holdings, LLC. - Case Study
AltaRock Energy, Inc. actively manages over 40,000 acres of geothermal leases on the western flank of Newberry Volcano in central Oregon. The leases, held by Davenport Newberry Holdings, LLC. (DNH) and administered by the US Bureau of Land Management, represents a unique opportunity to test and develop Enhanced Geothermal System (EGS) technologies in the field. In partnership with the US ...

World geothermal power generation nearing eruption
With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth’s heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total ...

New energy economy emerging in the United States
As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have ...

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 ...

A Cleaner Energy Future
As renewable energy plays an increasingly important role in the world’s energy portfolio, the standards of ASTM International Committee E44 are helping to pave the way for innovation in clean energy sources. A growing population and improving living standards around the world are causing significant increases in energy demand and competition for fossil fuels. These escalating energy ...

Personal Account: Stanford Geothermal Workshop
AltaRock Energy’s Matt Uddenberg accompanied a group of staff to this year’s Stanford Geothermal Conference, where AltaRock’s Susan Petty and Trenton Cladouhos gave a presentation on the Newberry EGS Demonstration. This was Matt’s first experience with the workshop, so we asked him to share his experience. Why I Went I was fortunate enough to have my first experience ...

Strada: How Our Geothermal Drilling Technology Works
The energy potential that lies beneath our feet has historically been measured by what can be achieved – and what can’t be. Strada exists because of that challenge. We’ve identified the issues raised by ultra deep geothermal drilling, and set out to solve them through game changing technology. That’s why we’re focused on hard rock drilling methods capable of drilling ...

Create new jobs & cut emissions by investing in renewable energy efficiency
At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...
