Energy Exchange

Postcard From Mark Brownstein In Tel Aviv, Israel

Source: Trekkie Gal

A lumber yard in the middle of Tel Aviv is an unlikely place to discover innovative new technology to transform ocean waves into energy, but there I was watching a demonstration of wave-to-energy technology in a makeshift wave tank constructed by Shmuel Ovadia.  Ovadia is a talented engineer passionate about harnessing the power of the ocean when he is not otherwise engaged in running his successful high-end lumber business.  See for yourself at:  http://www.sde.co.il/.

I suppose I shouldn’t have been surprised.  I am on the first day of a seven trip for U.S. energy leaders sponsored by Project Interchange, an educational institute of the American Jewish Committee, and by the time I arrived at Ovadia’s lumber yard in the late afternoon, I had already seen tremendous creativity in the unlikeliest places.  Our morning was spent walking down Tel Aviv’s Rothschild Boulevard, Israel’s equivalent of Silicon Valley, dropping by several of the technology incubators that are a large part of the reason why Israel is known as the “start-up nation.”  

Here, 20-somethings only a few years out of Israel’s army – where technology and project management skills are acquired and honed – are developing innovative software at a furious pace.  The aging, somewhat decrepit buildings dating back to Israel’s socialist early years, are brimming with entrepreneurial drive and youthful spirit.  Most interesting to me was a visit to the IDC Elevator, where Shmuel Chafets, Director of Business Development for Giza Venture Capital, described a recent investment in a start-up that is applying sophisticated software and smart grid technology to improve the efficiency of water delivery systems, which – among other things – anticipates leaks before they happen. 

In Israel, a nation increasingly reliant on energy-intensive desalination, saving water is also saving energy, a lesson at the heart of our report two years ago on the Energy-Water Nexus in Texas.  This visit got me wondering whether this same technology might be helpful in EDF’s efforts to partner with gas utilities to reduce methane leaks along their distribution systems.  Surely such smart grid ingenuity can be used to help fight the causes of global warming and not just the fresh water scarcity that is one of its many symptoms?

While software companies in Israel do well in attracting venture capital from the United States, Europe and, more recently, Southeast Asia, guys like Shmuel Ovadia struggle to attract capital to their bright ideas.  Even venture capitalists like to see commercial scale prototypes before investing major dollars, and good-old fashioned mechanical technologies are a whole lot more physically difficult and expensive to get to commercial scale than software solutions.  So it takes a special type of investor to risk the serious capital it takes to bring a hardware solution to market. 

It is a challenge, but not impossible, as our visit to Better Place’s Tel Aviv showroom demonstrated.  Here, we were treated to a test drive of the Renault Fluence ZE, an all-electric four passenger sedan, that has a range of approximately 100 miles and a battery that can either be recharged at home or our work or swapped out in a 5-minute visit to a Better Place ‘refueling’ station.  When you buy the car (and had we been Israelis, sales people were there ready to take our order), you buy a contract for miles to go with it.  Included in that contract are up to two charging stations, the electricity they supply, and access to any of Better Place’s battery swapping stations now being constructed throughout Israel. 

In short, the Better Place’s Renault Fluence is like the cell phone I have carried with me to Israel.  It is my phone, but I purchase the international sym card and the corresponding minutes of voice and data from Orange, a local carrier, which is easily slipped into the phone and recharged with new minutes as needed. 

Tomorrow we head down south to the Negev to see what is brewing in the world of solar energy.  I can only imagine what surprises await us.  I’ll keep you posted.

Tenaska Coal Plant to Usher in New Era of Carbon Capture and Storage, Water Conservation

You’ve heard us say before that we are not champions of coal, but we are realists.

Realists can also be idealists. We still want the same things – cleaner air and water, and clean, sustainable energy – and yet we know that the transition away from fossil fuels as a major energy source will take some time and require interim collaborative solutions.

We seek solutions that will work until the day comes that all energy is clean and non-polluting. So it is, that today we agreed not to oppose the Tenaska power plant in Sweetwater, Texas.  Read More »

Texas Solar Plant Sets New Trend with Water Saving Technology

The blog was co-authored by Amy Hardberger, an attorney in the EDF Texas office who specializes in the energy-water nexus.

The hard truth is this: Texas will need more electricity as it continues to grow. This means we’ll have to make some tough choices in the future to balance the needs of our economy with the environment. 

Renewable energy, particularly solar, is an important piece of the solution.  As more large solar projects are proposed, regulators, local citizens and developers will need to weigh economic development opportunities with wildlife and land preservation.  In Texas, EDF has been involved in many of these issues, especially the use of water as it relates to power plants.

Renewable energy can be water efficient

Conventional power plants, such as nuclear and coal plants, are well known as high consumers of water, but renewable power is a different story.  Photovoltaic solar projects in Texas require little to no water. 

A lesser known, but very promising solar technology is Concentrating Solar Power (CSP).  CSP uses conventional power plant technology coupled with highly concentrated sunlight to avoid the use of fossil fuels. 

Texas can lead the renewables industry in water efficiency

In terms of water use, CSP developers have traditionally relied on more conventional water-based cooling systems. However, there is a  shift to dry-cooled systems, a more water efficient system – reducing water usage by as much as 90%. This is good news since most CSP projects are proposed in places with a lot of sun and not a lot of water.

Texas may be at the forefront of a utilizing CSP in an even more water efficient way. Texas’ first CSP project is being developed by Tessera Solar. Their design features a technology that uses no water in the electric generation process. The only water needed is to clean the system.

In other locations, Solar Millennium announced its decision to change a planned project in Nevada to dry cooling in November of last year, and BrightSource Energy has chosen to use dry-cooling for all of its projects. 

Texas and a solar boom

This couldn’t come at a better time for Texas. The Public Utilities Commission is finally considering a rule to implement renewable energy goals for non-wind resources from a bill passed in the 2005 Texas Legislative Session that will help kick start solar in Texas.  Meanwhile, conventional power plants that are being proposed have some cities proposing the equivalent of taking out a second mortgage on their water supply

Texas is well positioned for a solar boom to rival the last decade’s wind boom, and we’re glad to see that solar companies are reading the writing on the wall. Trying to find water in the desert is like trying to find a needle in a haystack.  Why waste your time, when you can avoid the haystack all together?

Understanding the water and energy relationship

Most people who watch the news are aware that we have both energy and water problems in Texas.  What a lot of people may not realize is that these two issues are related and affect the water we use every day and the energy we bring into our homes. 

In order to better understand this relationship, I helped author a new report with the University of Texas Jackson School called Energy-Water Nexus in Texas that was released today. Check out the video below which gives a quick summary of the report’s findings.

[kml_flashembed movie="http://www.youtube.com/v/lWNoNu0MpPM" width="375" height="300" wmode="transparent" /]

The truth is that energy and water are related in just about every way you can imagine.  The water supply sector utilizes large amounts of energy to transport, treat, and deliver water.  On the flip side, vast quantities of water are required to generate power.

As Texas continues to grow and pressure increases on our water and energy resources, the linkages between water and energy become more important.  The cycle goes like this: A growing community needs more power, which requires more water, which uses more power, and so on.

Understanding this relationship highlights the importance of conserving water and practicing energy efficiency.  For every kilowatt saved, water is also saved.  For every gallon of water not used, energy demand is reduced. Investments in and incentives for energy and water conservation must be our highest priority.

How clean energy just overtook coal in this competitive electricity market

Look around the U.S. and you’ll find plenty of examples of smart policy that is driving the adoption of cleaner, more efficient energy resources. In particular, California, New York, and Illinois are all leveraging policy to reduce carbon pollution and transition to a 21st century electric grid.

But in addition to those success stories, markets also are achieving significant clean energy results – and nowhere is that more evident than here in Texas.

In 2001, the Lone Star State transitioned to a competitive electricity market that (for the most part) puts the cheapest energy resources on the grid first. Since then, wind has grown from supplying less than 1 percent of the state’s electricity to over 20 percent for the first half of 2017. And as cheap natural gas remains plentiful and renewable costs keep falling, expensive coal is getting pushed out of Texas’ market. In fact, wind power capacity just overtook coal capacity.

Saving Energy and Doubling Worldwide Water Supplies – One Drip at a Time

Netafim HQOn a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.

Naty Barak, the Netafim director who I met on the visit, notes that if the world’s farmers increased their use of drip irrigation to 15 percent (up from just under 5 percent now), the amount of water available for use worldwide could double.

Drip irrigation saves more than water. Whereas traditional irrigation typically uses quite a bit of energy, drip reduces the pressure (and power) needed to get the water to the crops while reducing the need for energy-hungry fertilizers. Plus, due to the inextricable link between water and power, saving water results in further saved energy.

Texas has already enhanced its water efficiency, but it could go further and take a page out of Israel’s book. By investing in thoughtful drip irrigation now, Texas could lead the nation on expanding this innovative technology and significantly reduce the energy footprint of its irrigation sector, while protecting water supplies for our growing cities and creating more sustainable farming practices.
