Jeremy Hobson:In the energy business there are renewables like wind and solar. And there are non-renewables -- like oil. Once you use up the oil that's in the well. That's it. Well, actually, a few researchers and entrepreneurs in Texas say that's not it.

Andrew Oxford reports.

Andrew Oxford:In his office at the University of Texas, geologist Bruce Cutright is pouring over maps and charts.

Bruce Cutright:This is just a picture of the number of wells there are in Texas -- existing wells -- somewhere between 1.2 and 1.4 million.

He is trying to show me what oil and gas companies usually don't see when their wells dry up. Those wells, Cutright says, are more than just holes in the ground.

Cutright:As you drill deeper into the Earth, it gets hotter and hotter. By the time you're below 12,000 feet, you're encountering temperatures above 300 degrees Fahrenheit.

All that heat, Cutright says, could be used to create geothermal power. Usually, it's generated by harnessing the heat from hot water near the surface -- geysers, for example. Drilling for that heat has long been considered too expensive. If someone else has already drilled a hole for you, it could be much more affordable. That's where entrepreneurs like Frank Smith come in.

Frank Smith:The oil and gas guys have no interest in water because when they see water they say "uh, my well is done."

But water is just what Smith is looking for. Smith is the CEO of Sologen Systems, a start-up in San Antonio that is repurposing oil and gas wells to generate geothermal energy.

Smith:We're using hot salt water. The water is already heated we just have to bring it up to the surface, extract the heat out of it, and put it back in the ground.

Smith is ready to start producing power. While each well only produces enough energy for a few hundred homes at best, connect several wells on a single acre and it can add up. But, when it is all added up, can geothermal compete with the low cost of fossil fuels?

Uday Turaga:Oil and gas developers are saying, "Why shouldn't I just continue drilling for oil and gas?"

Uday Turaga runs ADI Analytics, an energy consulting firm in Houston. He says a hydrofracturing boom is keeping oil and gas prices low. There is uncertainty around renewable energy incentives and many investors are staying away from geothermal.

Turaga:I would say interest is fairly low so someone has to do it on a commercial scale for the first time.

That is exactly what Sologen aims to do with just a few of the more than one million wells already drilled across Texas.

In San Antonio, I'm Andrew Oxford for Marketplace.

(Reuters) - The current design of the wholesale power market in Texas will not encourage needed investment in new power plants, the Brattle Group said in a report commissioned by the state electric grid operator.

Texas electric regulators and the grid agency that oversees the $34 billion deregulated wholesale market are working to encourage construction of new generation in the state, which has little ability to import power from its neighbors.

Unlike many areas of the United States, electric demand in Texas continues to grow because of the state's healthy economy.

"Electric reliability matters to all of us and we must remain focused on the central question of whether we are doing enough to guarantee an adequate power supply," said Craven Crowell, chairman of the Electric Reliability Council of Texas.

ERCOT, which oversees the grid for most of the state, has warned that the prospect for rolling blackouts in future years will increase as the power supply is unable to keep pace with growing demand.

Low wholesale prices and tight financial markets have stalled development of new generation in Texas even as more stringent environmental rules threaten to shut older coal- and gas-fired plants over the next few years.

"The cold hard fact is that new power plants will not be built unless power prices support that build," said Bill Nordlund, managing director of Panda Power Funds. Panda has two natural gas-fired plants primed for construction in Texas.

Last summer's protracted heat wave, which triggered record electricity demand and six emergency declarations from ERCOT, intensified the need to address the state's shrinking power reserve margin, the cushion needed to avoid blackouts.

The report by the Brattle Group, a power industry consultant, did not recommend a specific course of action to modify ERCOT's "energy-only" market, which pays generators only when they produce power, but outlined five options along with advantages and disadvantages of each.

Brattle principal Sam Newell said the energy-only market has worked well to attract generation investment in Texas, but low wholesale prices now will not encourage as many new megawatts as regulators believe are necessary to meet a 13.75 percent reserve margin in the summer when electric use soars.

Newell said Texans should reexamine that reserve target given the fact that power line problems are the cause of many more outages than supply shortages.

"You can plan on a very high level of reserves and almost never, ever have to shed load, but that would be more expensive than maintaining a lower reserve margin," Newell said on a call with reporters. "There's got to be a balance somewhere. We think it's worth re-evaluating those standards."

If the commission decides the state requires a higher reserve margin than the energy-only margin will provide, Brattle offered several potential solutions.

Options included keeping the energy-only design, but adding a market-based reserve margin; higher prices to support a target reserve margin; or a back-stop procurement process to maintain minimum acceptable reliability.

Other options included a mandatory resource adequacy requirement for companies that supply power to customers, or having a resource-adequacy requirement with a centralized forward capacity market.

While the Texas Public Utility Commission has resisted calls to create a capacity market similar to those used in other U.S. power markets, the Brattle report addressed a number of criticisms that capacity markets simply boost overall costs that benefit existing generation owners without attracting new power plants.

The PUC and ERCOT have already implemented a number of market changes, including raising the price cap on wholesale power when supplies are scarce, to encourage construction of new power plants.

"The Brattle Group's report confirms that we are moving in the right direction," said Donna Nelson, PUC chairman.

Unlike what the commission has proposed, however, the Brattle Group advised ERCOT to gradually increase the wholesale price cap to $9,000 per megawatt-hour from $3,000 MWh, reaching $9,000 only in extreme scarcity when power to customers is being curtailed. These prices would be paid by the suppliers who serve homes and businesses.

"We like scarcity prices to progress over a range instead of jumping to the cap (because) with a smoother price curve, you have better market behavior and it will work better with demand response," Newell said.

The report warned that simply increasing price caps will not attract more generation.

"Many market participants that were supportive of the commission's actions so far were wary of the prospect of raising caps much higher," the report said.

The Sierra Club criticized the report for its limited look at energy efficiency and conservation options where customers are paid to reduce power use when supplies are strained.

"Instead of using our money to build more coal and gas plants, the PUC should implement their rules proposed to raise energy efficiency goals," said Cyrus Reed, conservation director of the Lone Star Chapter of the Sierra Club.

The Brattle report said expanded demand-response programs will be needed, but that over the long-term the state will have to see new power plants built.

Reed also called on the state to increase use of renewable power, such as solar. Texas is already the No. 1 state for wind generation.

The Brattle Group noted that growth of wind power in Texas has depressed wholesale prices to the point that generators cannot justify investment in new gas-fired power plants.

John Ragan, president of NRG Energy's ( NRG.N ) Gulf Coast region, complemented regulators and ERCOT for seeking "expert, external analysis of the different options Texas can implement to encourage greater resource adequacy while maintaining a strong commitment to competition and regulatory certainty."

"I am confident that we can address the issues that we face," Ragan said.

A new report on the state of the solar industry in America indicates that despite a global oversupply and a potential trade war with China , the U.S. solar industry had its second-best quarter ever in terms of installations, during the first quarter of 2012.

The number of installations, 506 megawatts worth, enough to power just over 350,000 homes , was bested only by the fourth quarter of 2011, which saw a whopping 708 megawatts worth of solar installed.

On top of that, the report , drafted by clean-energy market analysis firm GTM Research and the Solar Energy Industries Association and released Tuesday, a trade group, forecasts that total U.S. installed solar power will increase 75 percent his year alone, with 3.3 gigawatts-worth of solar power installed, compared to the 4.4 gigawatts that are currently installed in the country and were added over years of development.

“This will be by far the largest year we’ve ever had for solar in the U.S.,” said  Shayle Kann , vice president of research at GTM , in a phone interview with TPM. “Relative to expectations, the first quarter was very strong. We saw both the commercial and residential markets grow.”

Indeed, commercial solar installations, those put in place on corporate properties, accounted for the overwhelming majority’s worth of solar power installed in the quarter — 288.8 megawatts, according to the GTM and SEIA U.S. Solar Market Insight report .

Furthermore, residential power installations (those installed on homes) accounted for 93.9 megawatts. The final category, utilities power installations, or solar put in place by power companies, accounted for 123.6 megawatts of installations, but that number was actually a steep decline from both the third and fourth quarters of 2011.

However, as the report points out, “direct comparisons between these two quarters [fourth and first] carry little meaning,” because “construction timelines for a relatively few large projects can cause large swings from quarter to quarter more than any underlying market dynamics.”

In essence: The natural construction cycle for solar projects and other power installations, governed by weather and the fiscal year, means that generally, utilities won’t be installing solar panels in larger numbers until later in the year, so long as they have those projects already lined up, “in the pipeline,” as it were.

“The pipeline is still huge,” Kann told TPM.

Intriguingly, when it came to the state-by-state breakdown for solar installations for the first quarter of 2012, New Jersey lead the nation in solar installations, with a whopping 173.8 megawatts of solar power generation capacity installed in the three month period. California, more commonly associated with solar, was second with 148.4 megawatts.

“New Jersey has been a leader in solar for years thanks to good state level policy,” Kann explained, “That’s the most important thing.”

Kann pointing to the state’s Solar Renewable Energy Certificates (SREC) program , which allows solar installation owner to sell credits on a competitive state market , credits earned for every 1,000 kilowatt-hours of electricity every single project generates. He said that other states were wise to follow in New Jersey’s path.

At the same time, domestic solar manufacturing took a hit as prices for some solar panel arrays plummeted by 47 percent over the same quarter last year.

The manufacturing downturn was taken as proof positive by the Coalition For Solar Manufacturing, a trade grouped formed specifically to petition the U.S. government to slap tariffs on Chinese imports of cheap solar panels, which the group says were illegally subsidized and dumped. The Commerce Department did find some Chinese companies guilty of illegally subsidizing and dumping , and did end up imposing tariffs.

As Gordon Brisner, president of SolarWorld America, the lead company in CASM, said in a statement distributed to reporters this week: “The sharp drop in U.S. solar manufacturing, even as demand in the United States grows, is powerful evidence of injury caused by unfair Chinese trade practices.”

Kann said that just because there was a global oversupply of solar panels driving down the price didn’t mean that China was necessarily dumping, though.

“Manufacturers across the globe didn’t prepare well,” Kann told TPM. “They kept producing even when their inventory was really high, which lead to a drastic market correction,” i.e., the falling price of solar panel modules.

Still, Kann said that the overall picture of the U.S. solar industry remained bright.

“We’re expecting see growth in all three sectors: residential, commercial and utilities,” Kann added.

Voluntary participation in renewable energy credits up 29 percent
May 15, 2012, AUSTIN, TX -- Texas posted a 13 percent increase in energy generated by renewable sources in 2011, according to the state’s renewable energy credits registry administered by the Electric Reliability Council of Texas (ERCOT), grid operator for most of the state.   The renewable energy recorded in the state’s renewable energy credit program was 31.7 million megawatt-hours (MWh) in 2011, compared to 28 million MWh in 2010 — a 13 percent increase — as reported in the Texas renewable energy credit program annual report , filed today at the Public Utility Commission of Texas (PUC). Wind generation represented the largest share at nearly 30.8 million MWh. Due to the ongoing drought in most of the state, generation of hydroelectric power decreased by more than half, while solar power generation more than doubled.

How Sologen’s plan to turn abandoned oil and gas wells into geothermal power producers could replace coal power in Texas.


By lemaster 17 Nov, 2017

Miles below Texas are zones of hot, pressurized brine that for decades posed a liability to drillers and rendered oil and gas wells worthless.

Now, new wildcatters are going after those same pools in the name of green energy. They want to use the pressure and heat to make electricity.

If successful, they will introduce a new source of clean power to the grid that has the potential to exceed all other sources.

According to a report by the Southern Methodist University Geothermal Laboratory, the hot water and pressure between 8,000 and 25,000 feet below Texas could supply more than 100 times the state's 2008 total electric consumption for well over a century.

The concept and technology of using the hot water from old oil and gas wells have been around in various forms since the 1960s. Since then, more than half a million oil and gas wells have been drilled in Texas.

The challenge always has been to make electricity production economical from those wells.

This summer, a Houston company will give it a try at a well in Liberty County. Also, a San Antonio company is working on financing a project to produce more than 100 megawatts in 12 months.

They and a handful of other companies have the support of the federal and state governments. A new state law provides tax incentives to companies producing electricity from oil and gas wells.

The Texas Public Utility Commission is working on rules to kick-start the geothermal market by requiring utilities to buy more clean energy. The commission did the same thing for wind power development, which is one reason Texas now is a national leader in wind energy production.

The federal government is issuing grants, including several in Texas, to accelerate the development of the geothermal market.

“There are millions of wells across the country and hundreds of thousands in Texas,” said Tim Reinhardt , who specializes in low-temperature geothermal development at the U.S. Energy Department . “We feel that this is a great thing.”

Southern Methodist University received $5 million to create a national geothermal database cataloging the millions of wells drilled across the country that could be used to generate electricity.

The U.S. Energy Department is investing another $5 million in El Paso County for the research and development of a geothermal system using new wells to produce electricity for Fort Bliss. The work is part of the post's effort to become self-sufficient.

“It's like gambling,” said Jon Lear , who works for a contractor on the Fort Bliss project. “You put a lot of chips out on a lot of different squares.”

This summer, George Alcorn , a third-generation oil and gas man, is setting out to prove he is worth betting on as he starts a demonstration project on a well outside Houston.

In 2008, with oil prices at record lows, Alcorn told his father he was doing the unthinkable and going green by opening up abandoned gas wells, not for the gas but for the 250-degree water that would gush to the surface. The hot liquid then would be used to create steam and turn a turbine before being injected back into the earth.

“I think a lot of guys his age and generation just can't fathom such an event,” Alcorn said of his 77-year-old father. “He's old school.”

Alcorn plans to start reconfiguring an abandoned 13,000-foot-deep gas well in Liberty County. He calls the well a “typical well,” in that it doesn't have exceptionally high temperatures or pressure. The idea is that if geothermal power can work on this well, this same technology could be applied to thousands of others.

He has the backing of a $1.5 million matching federal grant and expects to be producing about half a megawatt by December — enough to power about 75 homes.

It's not much in comparison to the hundreds of megawatts produced by geothermal plants on the West Coast. But those operations are built on top of or next to natural hot springs.

Texas does not have those kinds of formations. What it does have are more 500,000 oil and gas wells drilled since 1960.

“Some of our (oil) fields produce 10 times more water than oil,” said Jacques Beaudry-Losique , deputy assistant secretary for renewable energy at the Energy Department. “Some of it comes back pretty hot.”

Outside Victoria is a 41/2-mile-deep well with water at a recorded temperature of 510 degrees Fahrenheit, more than twice the boiling point. If exposed to the surface, the water would explode.

Along the Texas Coast are similar wells at slightly cooler temperatures but at thousands of pounds of pressure and capable of spewing continuous jets of brine hundreds of feet into the air.

It is that energy that Alcorn wants to tap. He envisions thousands of wells across Texas producing thousands of megawatts of clean power 24 hours a day.

Unlike wind and solar energy that's dependent on the weather, geothermal can produce power round the clock without fluctuation. The power generation also can be close to places where demand is high, making it more efficient than wind turbines that have to transmit power hundreds of miles.

Sologen Systems, a renewable energy development company in San Antonio, is betting on the abandoned wells of South and East Texas. It estimates they could produce 100 megawatts in 12 months — as soon as it secures funding.

But investors are cautious about the new technology, Sologen President Frank Smith said. They want assurance it will work and be profitable.

“You want to be on the cutting edge,” Smith said. “Not the bleeding edge.”

From late 1989 until early 1990, the Energy Department ran a demonstration plant at an old well on the Pleasant Bayou East near Houston that pumped out a steady megawatt of power. While clean and reliable, the energy was too expensive at the time to be marketable and the plant was shut down.

With the improvements in generators and the rising cost of energy, Alcorn believes the power now is marketable and has found investors to back his demonstration project.

“I feel like I'm wildcatting again,” Alcorn said. “I feel like I am out there taking the risks that no one else is taking.”

The person who figures out how to get that reliable clean energy to market cheaply will stand to make millions.

“My dad told me, ‘When you flip the switch, I want to be there,'” Alcorn said.

The United States Department of Energy (DOE) established a geopressured-geothermal energy program in the mid 1970's as one response to America's need to develop alternate energy resources in view of the increasing dependence on imported fossil fuel energy. This program continued for seventeen years and approximately two hundred million dollars were expended for various types of research and well testing to thoroughly investigate this alternate energy resource. The main goals of this program were to define the extent of the geopressured reservoirs, determine the technical feasibility of reservoir development including downhole, surface and disposal technologies, establish the economics of production, identify and mitigate adverse environmental impacts, identify and resolve legal and institutional barriers and determine the viability of commercial exploitation of this resource.

Geopressured-geothermal reservoirs occur in the United States most prominently along the northern Gulf of Mexico basin and the Pacific West Coast. Various estimates have been made regarding the recoverable natural gas from the geopressured-geothermal resources of the northern Gulf of Mexico basin and Dorfinan (1988) states that on an average approximately 250Tcf, equivalent to about 137% of known conventional methane reserves in the United States can be potentially extracted from this resource. The DOE program proved that long term high volume brine production was feasible and that gas-extracted brine could be successfully disposed by subsurface injection.

The U.S. Department of Energy’s geopressured-geothermal research program recommended that the ideal situation would involve the development of a total energy system in which all three associated forms of energy - chemical, thermal and mechanical are utilized. This U.S. DOE’S visionary research program has essentially laid the foundations for characterization of this resource and all aspects connected with its development.
