China’s thermal coal market may remain buoyant on multi factors

More news from China that confirms a significant jump in coal usage this year, and therefore most probably a jump in China's CO2 emissions.

"It is true that hot weather and lower-than-expected hydro output, partly for the control of floods, pushed up demand for coal-fired electricity in the past months. But, it is more persuasive that stronger power demand from the industrial sector is the major driver for sustained solid growth in coal demand. And, this is expected to underpin thermal coal demand continuously in the months ahead, after the end of the hot summer ... Daily coal consumption averaged 721,000 tonnes at China’s six major coastal utilities in July, up 10.5% from a year ago; while that reached 798,000 tonnes over August 1-18, rising 13.2% from the year prior, both far more than expected."

The Aussie Government is following the Trump Presidency game plan.

$2.5bn on a coal-fired power station? That's good old pork barrelling

"The Queensland Liberal-National party (LNP) are promising that if they are elected to government they’ll build a new coal power station in northern Queensland. And just this week the prime minister, Malcolm Turnbull, announced that if Queenslanders elected the LNP at the next state election, all Australian taxpayers would help fund it.

It’s important to note that this would involve a serious amount of taxpayers’ money, because banks and power companies have made it clear they aren’t remotely interested in funding such a plant."
"Para a Causa do Povo a Luta Continua!"

Washington state deals blow to plan for coal export terminal
OLYMPIA, Wash. (AP) — A company that wants to build and operate a large terminal to export coal from the western U.S. to Asia was denied a key permit by Washington state on Tuesday because of environmental concerns.

The Department of Ecology rejected a water quality permit that Millennium Bulk Terminals sought because the proposed facility near the city of Longview would have caused “significant and unavoidable harm” to the environment. The department cited effects to air quality, noise pollution and tribal resources, among others. ...

People who say it cannot be done should not interrupt those who are doing it.

Explosion today at a coal gasification plant in Tennessee. :o
The cause was described as "a process upset in the coal gasification area."  ::)

No serious injuries reported, but local roads were closed, and nearby residents were instructed to Shelter in Place due to the possibility of dangerous fumes.

Short clip of raw video of the explosion:  https://mobile.twitter.com/6News/status/915608834781192193

Coal production in the United States decreased 33 percent from 2011 to 2016, and according to a recent Columbia University report, just 3.5 percent of that decline was due to environmental regulations. Even Rick Perry’s long-awaited Department of Energy report identifies cheap natural gas as “the biggest contributor” to coal plant closures.

Adding further evidence, an analysis from the Union of Concerned Scientists (UCS) released Tuesday found that 19 percent of coal-fired power is economically unviable compared to alternative energy sources such as renewables and gas.

“The transition away from coal over the past decade is poised to continue -- thanks primarily to market forces,” said Jeremy Richardson, a senior energy analyst at UCS, lead author of the analysis, as well as the brother and son of West Virginia coal miners. "The fundamental economics around coal-fired electricity have not changed, and rolling back the Clean Power Plan -- which was designed to put the U.S. on a pathway toward reducing carbon emissions responsible for global warming -- isn’t going to change that."

Perhaps Short Finger Donnie's stomping on the Clean Power Plan won't have much impact on closing coal plants.  As the price of wind and solar continue to fall more of the 61% now viable will join the present 21% which are not economically viable.  18% of existing US coal plants are scheduled for closure or conversion to NG.

Hopefully Donnie doesn't manage to get subsidies for coal.  That could keep some plants open longer than otherwise.

Democrats need to regain control of one house of Congress next fall so that they can block harmful legislation.  When we get a sane person in the White House they can undo Donnie's proclamations.

Dutch government:  We're stopping coal.  You say you just recently built a coal plant?  Tough luck!

Netherlands to close all coal plants by 2030
Announcement today by Dutch government seen as progressive step for renewables in the country. New legislation requires all coal-fired generation plants to be idled by 2030 and to meet more stringent emissions limits from 2021.
The Dutch government this week sent a positive message to the country’s renewable energy sector with the introduction of legislation that will see all coal-fired generation plants close by 2030.

The news will come as a blow to three utilities that as recently as 2015 commissioned three coal plants in the Netherlands – the newest in Europe – but will be welcomed by clean energy advocates across Europe.

Engie, RWE and Uniper each invested heavily in Dutch coal plants completed in 2015, but now all three utilities will likely suffer massive losses on the write downs made on these coal plants, said Gerard Wynn, analyst at the Institute for Energy Economics and Financial Analysis (IEEFA). ...

Armed With NASA Data, South Korea Confronts Its Choking Smog
The government is taking some action now. South Korean President Moon Jae-in is overseeing a fine dust task force and is shuttering 10 of the country's oldest and most polluting coal plants. The city of Seoul issues fine dust alerts over mobile phones to better inform residents of dangerous days.

Gutting the clean power plan doesn’t halt the transition, but it’s likely to slow it down. And it’s going too slowly already.

Another couple gigawatt of coal bites the dust:

"The utility will retire its Sandow Power Plan and Big Brown Power Plant in Central Texas, taking a combined nameplate capacity of roughly 2,300 MW offline. "
