Let’s Not Coat Our Roads in Toxic Wastewater

Apparently this needs to be said.

Betteridge’s law of headlines, as defined by the journalist Ian Betteridge, states that any headline which ends in a question mark can be answered by the word “no.” This is probably especially true of a headline like the one that ran on Jake Bolster’s recent story for Inside Climate News, which read “Should Toxic Wastewater From Gas Drilling Be Spread on Pennsylvania Roads as a Dust and Snow Suppressant?”

There are many red flags here, starting with “toxic” and “wastewater.” But it also speaks to a larger problem: Most of the fluid that comes out of the ground during oil and gas drilling operations is wastewater — more than 800 billion gallons a year — and we don’t really have a good solution for what to do with it. As I wrote last year, injecting the water back into the ground, which has been the go-to method for disposing of it in many places, has created earthquakes in both Texas and Oklahoma. And, as Inside Climate News also reported in a story yesterday, oil and gas companies have been spilling millions of gallons of the stuff in Texas, contaminating wells and poisoning cattle.

The water that comes out of the ground is briny stuff, so some bright minds in the oil and gas industry have been trying to sell regulators on the idea that it can replace road salt, which is itself bad for the environment. According to Grist, 13 states, including Ohio, Indiana, Illinois, and Michigan, allow for the "beneficial use" of wastewater, including for de-icing roads, and industry representatives are now trying to convince Pennsylvania's Department of Environmental Protection to consider allowing its use in their state as well. But wastewater is more than just ancient, underground seawater — it also has benzene, arsenic, and the radioactive isotopes radium 226 and 228 riding in it.

Nobody in Pennsylvania is buying what the industry is selling. “It’s a terrible idea,” Bill Burgos, a professor of environmental engineering at Penn State, told Bolster. The wastewater, it turns out, washes right off the road without even suppressing dust. That still leaves the question of what to actually do with all that wastewater (here, perhaps, is where I point out that we wouldn’t have this problem if we, you know, stopped drilling for oil and gas).

As for the roads? Perhaps Pennsylvania should consider beets. It seems to be working for the Canadians.

The Country’s Largest Power Markets Are Getting More Gas

Three companies are joining forces to add at least a gigawatt of new generation by 2029. The question is whether they can actually do it.

Two of the biggest electricity markets in the country — the 13-state PJM Interconnection, which spans the Mid-Atlantic and the Midwest, and ERCOT, which covers nearly all of Texas — want more natural gas. Both are projecting immense increases in electricity demand thanks to data centers and electrification. And both have had bouts of market weirdness and dysfunction, with ERCOT experiencing spiky prices and even blackouts during extreme weather and PJM making enormous payouts largely to gas and coal operators to lock in their “capacity,” i.e. their ability to provide power when most needed.

Now a trio of companies, including the independent power producer NRG, the turbine manufacturer GE Vernova, and a subsidiary of the construction firm Kiewit Corporation, are teaming up with a plan to bring gas-powered plants to PJM and ERCOT, the companies announced today.

The three companies said that the new joint venture “will work to advance four projects totaling over 5 gigawatts” of natural gas combined cycle plants to the two power markets, with over a gigawatt coming by 2029. The companies said that they could eventually build 10 to 15 gigawatts “and expand to other areas across the U.S.”

So far, PJM and Texas’ call for new gas has been more widely heard than answered. The power producer Calpine said last year that it would look into developing more gas in PJM, but actual investment announcements have been scarce, although at least one gas plant scheduled to close has said it would stay open.

So far, across the country, planned new additions to the grid are still overwhelmingly solar and battery storage, according to the Energy Information Administration, whose data shows some 63 gigawatts of planned capacity scheduled to be added this year, with more than half being solar and over 80% being storage.
