Can green hydrogen save a coal town and slow climate change?

DELTA, Utah  — The coal plant is closing. On this tiny Utah city surrounded by cattle, alfalfa fields and scrub-lined desert highways, tons of of employees over the following few years will probably be laid off — casualties of environmental laws and competitors from cheaper vitality sources.

But throughout the road from the coal piles and furnace, beneath dusty fields, one other transformation is underway that would play a pivotal function in offering clear vitality and exchange a few of these jobs.

Right here within the rural Utah desert, builders plan to create caverns in historic salt dome formations underground the place they hope to retailer hydrogen gas at an unprecedented scale. The endeavor is one among a number of initiatives that would assist decide how large a job hydrogen will play globally in offering dependable, around-the-clock, carbon-free vitality sooner or later.

Catastrophic Climate Change Cannot Be Stopped If We Keep Using Coal


On the twenty sixth United Nations Convention on Local weather Change, diplomats put down on paper, for the primary time, the collective must speed up phasing out coal and fossil fuels subsidies to fulfill their local weather objectives in a draft assertion launched Wednesday.

Nations can both hold utilizing coal at present ranges or restrict future warming to the 1.5 levels Celsius (2.7 levels Fahrenheit) goal of the Paris local weather settlement. It’s not possible to do each. However this scientific actuality has been an elephant within the room of high-level worldwide local weather negotiations for years — till now.

“It’s important,” Helen Mountford, a vice chairman at World Sources Institute, instructed reporters. “We’ve by no means had a textual content like that earlier than.”

Nonetheless, this new declaration isn’t remaining, has no timeline or different particulars, and comes together with some murky country-specific pledges. This incongruity on coal captures the central rigidity taking part in out on the high-profile local weather talks in Glasgow: the obvious gaps between what nations should do to halt the worsening local weather disaster, what nations say they are going to do sooner or later, and what they’re really doing now.

“We’ll see if that textual content sticks,” Mountford later stated. “We’re hoping it’s going to. It’s a very vital and concrete motion that nations can take to truly ship on their commitments.”

Outdoors the local weather negotiations, protesters pushed for the language to remain in. In response to the Washington Submit, they chanted: “‘Fossil fuels’ on paper now” and “Hold it within the textual content.”

Even United Nations Secretary-Basic António Guterres expressed frustration with the negotiations on Thursday, saying that country-level “guarantees ring hole when the fossil gas trade nonetheless receives trillions in subsidies, as measured by the IMF. Or when nations are nonetheless constructing coal crops.”

With present local weather insurance policies in place, the world is on observe to heat greater than 2 levels Celsius (3.6 levels Fahrenheit) this century in comparison with preindustrial ranges. Even probably the most up-to-date tallies of present pledges for future local weather motion put the world on observe to warmth up 1.8 levels Celsius. Because of this even when all of the nations really ship on their most formidable guarantees — a giant if — we’ll nonetheless overshoot the important thing Paris aim by 0.3 levels. This will appear to be a minor distinction, however the science is abundantly clear that each tenth of a level is disastrous for humanity: extra frequent and intense warmth waves, droughts, hurricanes, and wildfires; extra sea degree rise; and, in the end, extra struggling.

The science can be clear that coal is simply terrible for the local weather. Coal is probably the most carbon-intensive power supply, answerable for about 40% of carbon emissions tied to international fossil gas use.

That’s why a rising variety of officers are saying that ditching coal is among the many most vital steps to take for tackling local weather change. Simply final week, for instance, Canadian atmosphere and local weather change minister Steven Guilbeault stated in Glasgow: “Ending emissions of coal energy is among the single most vital steps we should take to fulfill the objectives of the Paris local weather settlement and the 1.5 diploma goal.”
