How A Sand Battery Could Change The Energy Game

How A Sand Battery Could Change The Energy Game – Thermal Energy Storage Explained.

As you know, efficient energy storage systems are the conundrum of making the most out of intermittent renewable energy. Unless you’ve had your head in the sand, it’s a glaring problem we have to solve, which is why so many different battery technologies are being explored and developed. To the point that some of them are now coming out of the sand … that’s what recently happened in Finland where the world’s first commercial sand battery technology went live this past July. How does it work and is it a viable path for storing energy? Let’s see if we can come to a decision on this.

To Make Headway on Climate Change, Let’s Change the Subject

States point to the economic advantages of cleaning up their electric grids.

DENVER — The morning two years ago that Jared Polis announced his run for governor of Colorado, he went to a coffee roaster operating on solar power and promised more renewable energy for the state. Campaigning on that alongside education and health care reform, Mr. Polis, a Democrat, blew away his Republican opponent last fall by 11 percentage points.

This week, the clean-energy voters who helped put him into office will get their first reward. Mr. Polis is expected to sign a remarkable package of 13 environmental and energy bills that will propel Colorado to the top rank of states tackling the climate crisis.

Colorado stands out, but it does not stand alone. A wave of fresh ambition to confront climate change is sweeping through state governments as lawmakers point to the benefits: green jobs, lower electric rates and new tax revenues.
Six states have adopted policies that will effectively require the elimination of carbon dioxide emissions from their electric grids by midcentury, most of them in the past year. So many other states are considering it that the number could double in the next year or two.

This is happening mostly in states like Colorado where Democrats have taken full control of state government, and I think the trend holds important lessons for the Democratic Party. At the national level, the Democrats need to start running hard on climate and energy, instead of paying the issue lip service.

Signs abound that the American public is ready for a serious discussion about our energy options. But how to discuss the subject? For that we should look not just to states like Colorado but, interestingly enough, also to a state under complete Republican control: South Carolina.

This received little national attention, but the South Carolina legislature just adopted a bold policy meant to open the state to more solar power. Utilities like Duke Energy may yet torpedo the plan, but if they are beaten back, South Carolina in a few years could match North Carolina in getting 5 percent of its electrical power from the sun, compared with less than 1 percent last year.

The solar bill is part of the ongoing recuperation in South Carolina from an attempt to build a new nuclear power plant. That turned into a debacle, with repeated cost overruns and construction problems finally leading to the cancellation of the plant. South Carolinians will be paying for their $9 billion hole in the ground for many years to come.

In the aftermath of that mess, the solar industry swooped in and offered to put a lot of clean power onto the grid. The industry was careful with words, though. Tyler Norris, who helped craft the bill on behalf of South Carolina’s solar industry association, told me that the focus was on the direct benefits to the people of the state.

I don’t know that the terms ‘climate change’ or ‘global warming’ were ever uttered in the entire year and a half of advocacy and debate around this,” Mr. Norris said.

The final vote in the South Carolina Senate was 46-0, and in the House, 103-0. You read that right.

The champion of the Energy Freedom Act, a Republican state senator named Tom Davis, explained his thinking last week, writing in an op-ed that the bill was a step toward “real competition that will provide downward pressure on the cost of producing energy.”

He is right: We are entering an era when clean electricity is going to be the cheapest electricity. That means monopolies like Duke Energy are about to get stuck with a bunch of dirty, coal-burning power plants that are becoming uneconomical.

Some utilities, it must be said, are turning into clean-energy champions. The leading one in the country is Xcel Energy, which happens to supply much of urban Colorado with power and operates in seven other states. The company has been ramping up its clean-energy commitments for years; after Mr. Polis was elected but before he took office, it committed to going 100 percent clean by 2050.

Mr. Polis, working with a legislature controlled by Democrats, wrote into law a mandatory 80 percent reduction in emissions for Xcel by 2030, along with a broader target of reducing emissions from the entire Colorado economy 90 percent by 2050. The legislative package includes a big push for electric cars, as well as measures to ensure fair treatment for workers laid off from dirty power plants.

“Colorado prides itself on being an innovative, forward-looking state,” Mr. Polis told me. “We want to lead as a state to make sure Colorado is well positioned for the renewable-energy future.”

The clean-energy picture has evolved so rapidly in the past few years that I think the situation calls for a strategic shift on the part of the Democrats. Wagging fingers in the Republicans’ faces about their climate denial has not worked. Demanding that they pass punitive fuel taxes has not worked. What seems to be working is to emphasize the local and statewide benefits of clean energy.

Senator Chuck Grassley, Republican of Iowa, likes wind energy because it is good for the farmers who get paid to host turbines. School boards in Kansas and Oklahoma love it because the taxes on wind parks are filling their coffers. In the South, people are figuring out that solar panels can put out cheap power just about the time they are cranking up their air-conditioners.

As the economic case for renewables grows more compelling, the issue becomes how much faster we can go in cleaning up the grid. The tactical goal for Democrats is not to get Republicans to admit they have been wrong about climate science; the only thing that matters is to pass measures to speed the energy transition.

Understanding all this, Democrats can still run hard on climate change in party primaries. But in general elections and upon taking office, they need to make the subtle shift from talking about the climate crisis to talking about the benefits of clean energy — something that Mr. Polis, for one, is skilled at doing.

The polls have told us, over and over, that right below the surface in this country lurks a powerful consensus to go all out on the energy transition. The falling costs offer a fresh opportunity to talk about competition and freedom of choice in the market for electricity, a language that many Republicans understand.

That unanimous measure in South Carolina tells you that for the right policies advocated in the right language, the votes are there.

Who’s Afraid of Nancy Pelosi?

What has Pelosi achieved?

First, as House minority leader, she played a crucial role in turning back George W. Bush’s attempt to privatize Social Security.

.. Then she was the key figure, arguably even more crucial than President Barack Obama, in passing the Affordable Care Act, which produced a spectacular fall in the number of uninsured Americans and has proved surprisingly robust even in the face of Trumpian sabotage.

She helped enact financial reform, which has turned out to be more vulnerable to being undermined, but still helped stabilize the economy and protected many Americans from fraud.

Pelosi also helped pass the Obama stimulus plan, which economists overwhelmingly agree mitigated job losses from the financial crisis, as well as playing a role in laying the foundation for a green energy revolution.

.. whenever you hear Republicans claim that Pelosi is some kind of wild-eyed leftist, ask yourself, what’s so radical about protecting retirement income, expanding health care and reining in runaway bankers?

It’s probably also worth noting that Pelosi has been untouched by allegations of personal scandal, which is amazing given the right’s ability to manufacture such allegations out of thin air.

Canada Backtracks on a Carbon Tax

Justin Trudeau’s Liberals try to stop a stampede of capital out of the country.

The new carbon tax is only one of the green policies hurting Canada’s competitiveness. Ontario has long been the nation’s manufacturing hub. But in 2005 the province began phasing out the use of coal for electricity generation, and in 2009 it passed the Green Energy Act, designed to force industry and consumers into renewable energy. The net effect has been skyrocketing electricity prices in the province and declining manufacturing output.

.. Ontario, under new political management since June, and Saskatchewan have gone to court to challenge the federal government’s authority to impose the tax. Prince Edward Island, New Brunswick and Manitoba have their own proposals to price carbon and are all on record against a federal take.

In Alberta, where the economy depends heavily on pumping oil, the United Conservative Party’s Jason Kenney is the favorite to win next year’s election for provincial premier. He has promised to oppose the Trudeau tax. He says he will keep a provincial carbon tax but limit it to “major emitters.”

Canadian Environment Minister Catherine McKenna said last week that the Trudeau government wants “to have the most energy efficient, smart industries here that create good jobs, at the same time do what we need to do to tackle emissions.” But Liberals may soon find out that as one of the world’s foremost energy producers, Canada can’t have it both ways.
