Good News, Bad News & Urgent Action Needed on Frac Sand

LANDSTEWARDSHIP ALERT: Good news, Bad News & Urgent Action Needed on Frac Sand

The good news is that on the front page of today’s Star Tribune, Governor Mark Dayton said this about Sen. Matt Schmit’s provisions to protect trout streams in southeast Minnesota (including a one mile setback): “I strongly support that position and will do everything I can in conference committee to get it enacted.’’

The bad news is that the Governor met with a group of frac sand industry lobbyists today. Despite several requests for a meeting from groups representing citizens affected by frac sand mining, we have not had the same opportunity this legislative session. That the Governor is hearing from one side only is a cause for concern. If the Governor maintains his commitment to the trout stream protections, including the one mile setback, we have a good shot at getting them passed. If his commitment softens, our chances are slim.

Take action! Call Gov. Dayton IMMEDIATELY at 651-201-3400 or 800-657-3717, and e-mail him HERE. If you use Facebook, post on Gov. Dayton’s official Facebook page under the fishing opener post or message him on his personal Facebook page .

Message to Gov. Dayton: “I saw the story in the Star Tribune today and am very glad to see that you are strongly supporting a one mile setback from trout streams for frac sand mines in southeast Minnesota. We need some standards in place now that clearly put these most sensitive areas off limits to frac sand mining. I also saw that you met with frac sand lobbyists today. While environmental review is good, it is not, as the industry claims, a standard that protects our community. I urge you to stick to the one mile setback. Once the damage is done, it cannot be undone. We must protect this resource now. I hope you will not consider changing your mind because of today’s meeting. If you are reconsidering your views on this issue, I think you should also meet with people from southeast Minnesota whose communities are on the line.”

This issue is being negotiated now, so we need calls and e-mails immediately.

Join us at the Capitol. We expect Sen. Schmit to offer his amendment on the Senate floor tomorrow and will be gathering at 10:30 a.m. in front of the Senate chambers at the Capitol to show our support. If you plan to attend, let Bobby King know at bking@landstewardshipproject.org.

These provisions that Sen. Schmit developed with Minnesota Trout Unlimited say that for southeast Minnesota’s driftless area (roughly the five counties that are in southeast Minnesota):

  • No frac sand mining is allowed within one mile of any spring, groundwater seepage area, fen, designated trout stream, class 2a water or any tributary of class 2a water or designated trout stream.
  • The DNR cannot issue groundwater appropriation permits for frac sand-related activity, including frac sand processing. (These permits are necessary when over a million gallons of groundwater a year will be used.)
  • Mining frac sand within 25 feet of the water table is prohibited.

These provisions protecting trout streams would help dramatically in limiting the harm frac sand mining can do in southeast Minnesota, and would go into effect immediately. Without a moratorium, we need standards in place NOW before anymore frac sand mines or processing facilities are established in southeast Minnesota. For more details on the language proposed in the amendment, go to LSP’s website HERE.

Some people think a widespread shift from fossil fuels to cleaner energy sources is not practical or even possible. You’ve probably heard the arguments: wind doesn’t always blow, sun doesn’t always shine, the technology’s not advanced enough, installations take up too much space, we need sources of baseload power that can only come from fossil fuels or nuclear power. And so we carry on, rushing to squeeze every last drop of oil and gas from the ground using increasingly difficult and destructive methods like fracking, deep-sea drilling and oil sands extraction, with seemingly little concern for what we’ll do after we’ve burned it all.

low-cost, long-life battery enables solar, wind to be major grid suppliers

New Battery Design Could Help Solar and Wind Energy Power the Grid

April 24, 2013

Menlo Park, Calif. — Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.

“For solar and wind power to be used in a significant way, we need a battery made of economical materials that are easy to scale and still efficient,” said Yi Cui, a Stanford associate professor of materials science and engineering and a member of the Stanford Institute for Materials and Energy Sciences, a SLAC/Stanford joint institute. “We believe our new battery may be the best yet designed to regulate the natural fluctuations of these alternative energies.”

Cui and colleagues report their research results, some of the earliest supported by the DOE’s new Joint Center for Energy Storage Research battery hub, in the May issue of Energy & Environmental Science.

Currently the electrical grid cannot tolerate large and sudden power fluctuations caused by wide swings in sunlight and wind. As solar and wind’s combined contributions to an electrical grid approach 20 percent, energy storage systems must be available to smooth out the peaks and valleys of this “intermittent” power – storing excess energy and discharging when input drops.

Among the most promising batteries for intermittent grid storage today are “flow” batteries, because it’s relatively simple to scale their tanks, pumps and pipes to the sizes needed to handle large capacities of energy. The new flow battery developed by Cui’s group has a simplified, less expensive design that presents a potentially viable solution for large-scale production.

Today’s flow batteries pump two different liquids through an interaction chamber where dissolved molecules undergo chemical reactions that store or give up energy. The chamber contains a membrane that only allows ions not involved in reactions to pass between the liquids while keeping the active ions physically separated. This battery design has two major drawbacks: the high cost of liquids containing rare materials such as vanadium – especially in the huge quantities needed for grid storage – and the membrane, which is also very expensive and requires frequent maintenance.

The new Stanford/SLAC battery design uses only one stream of molecules and does not need a membrane at all. Its molecules mostly consist of the relatively inexpensive elements lithium and sulfur, which interact with a piece of lithium metal coated with a barrier that permits electrons to pass without degrading the metal. When discharging, the molecules, called lithium polysulfides, absorb lithium ions; when charging, they lose them back into the liquid. The entire molecular stream is dissolved in an organic solvent, which doesn’t have the corrosion issues of water-based flow batteries.

“In initial lab tests, the new battery also retained excellent energy-storage performance through more than 2,000 charges and discharges, equivalent to more than 5.5 years of daily cycles,” Cui said.

To demonstrate their concept, the researchers created a miniature system using simple glassware. Adding a lithium polysulfide solution to the flask immediately produces electricity that lights an LED.

A utility version of the new battery would be scaled up to store many megawatt-hours of energy.

In the future, Cui’s group plans to make a laboratory-scale system to optimize its energy storage process and identify potential engineering issues, and to start discussions with potential hosts for a full-scale field-demonstration unit.

Tarsand Oil Pipeline to Arctic Ocean Mulled by Alberta, Canada

Pipeline to Arctic Ocean Mulled by Canada

Calgary firm hired to do feasibility study of pumping oilsands bitumen to Tuktoyaktuk 23 Apr 2013

by CBC News [Link]

The government of Canada’s province of Alberta is looking at yet another pipeline option to get its oil to market should the Keystone XL or Northern Gateway pipeline proposals not come to fruition.

Calgary consulting firm Canatec Associates International Ltd. has been hired by the province to study the feasibility of moving crude from the oilsands up to a port in the Northwest Territories. It has been estimated $30 billion dollars a year stays locked in Alberta’s oilsands because there is no way to get it to market.

TransCanada’s Keystone XL pipeline to the Texas Gulf Coast still needs the approval of the U.S. State Department and President Barak Obama. Its proposal to convert an existing pipeline to pump bitumen eastward to refineries in Quebec and New Brunswick is also controversial.

Meantime, Enbridge’s pipeline proposal west to Kitimat is meeting with fierce resistance in B.C. from environmentalists and Aboriginal groups.

So the Alberta government is looking at another option to build a pipeline from the oilsands up the McKenzie River Valley to a proposed deep-water port at Tuktoyaktuk, a community in Canada’s Northwest Territories (N.W.T.) Continue reading
