http://productiongap.org/

Governments are planning to produce about 50% more fossil fuels by 2030 than would be consistent with limiting warming to 2°C and 120% more than would be consistent with limiting warming to 1.5°C.

Collectively, countries’ planned fossil fuel production not only exceeds 1.5°C and 2°C pathways, it also surpasses production levels consistent with the implementation of the national climate policies and ambitions in countries’ NDCs. As a consequence, the production gap is wider than the emissions gap.

Indeed, though many governments plan to decrease their emissions, they are signalling the opposite when it comes to fossil fuel production, with plans and projections for expansion. This hinders the collective ability of countries to meet global climate goals, and it further widens not just the production gap, but the emissions gap as well.

That of course is what governments do, they have meetings and sign agreements off in the future figuring whoever replaces them will have to deal with it.  Then they pony out some PR scale projects to create the appearance they are DOING something of substance.

Meanwhile, in the real world, things continue apace.  But they SOUND good, and they are able to fool many.

Probably paid for by Exxon.


so, is filling a landfill a bigger issue than burning coal?

from the article........


MidAmerican’s Greenwood says the utility plans to spend $2.3 billion to repower 1,215 turbines across the state through 2022.

Consumers will pay none of the wind costs, Greenwood said. In fact, MidAmerican has said the utility will receive about $10 billion in federal production tax credits for the investment, covering the capital costs needed to build the wind farms.

MidAmerican Energy has set a goal to create as much energy from wind as its 770,000 Iowa electric customers use over a year. So far, it’s reached about 50%.

Despite the big investment, coal is still Iowa’s largest source of energy to produce electricity, followed by wind and other renewable energy and natural gas. Iowa gets 34% of its electricity from wind, the second-largest proportion in the nation after Kansas at 36%.

I personally think coal is by far the worst thing to use to generate electricity.  My own approach would be to try and replace every coal plant (nearly) in the US in a decade, at least going to NG is a good step, and that is happening due to market forces of course.  The fly ash from coal is a big problem as well.

https://undark.org/2019/11/13/cement-carbon-green-concrete/

Cement is one of the global economy’s most carbon-polluting industries. Responsible for about 8 percent of global carbon dioxide (CO2) emissions in 2015, if it were ranked with individual countries, the cement industry would be the third-largest greenhouse-gas emitter in the world behind only China and the United States. And this already outsized footprint is only projected to grow in the coming decades as economic development and rapid urbanization continue across Southeast Asia and sub-Saharan Africa. According to the International Energy Agency and the Cement Sustainability Initiative, by 2050 cement production could increase by as much as 23 percent.

A real-world demonstration of their product is taking shape in Georgia at a multi-story commercial office building under construction in one of Atlanta’s hippest neighborhoods. Set to be completed by the end of the year, the building will be the first large-scale development to use concrete made with CarbonCure throughout the entire structure.

I laughed at "hippest neighborhoods" comment.  I guess it is in a way, it's not far from us at all, walking distance.

One thing I saw in spades at work was "imagery", basically style over substance.  When I was young, I was often drawn in to the pitch, after all, you want to believe your leaders are leading and telling the truth and great things are happening.  Of course, after a decade or so, this became impossible, fool me once etc.

The more experienced folks tried to warn me, but I really had to learn it myself.  And the young folks I tried to warn had excuses just as I did.

I got so jaded and cynical I didn't believe anything, which was perhaps an over reaction, but not by much, if any.  It was somewhat similar to 1984.  Really.  What WAS true two years before was now to be forgotten because of this NEW truth.  Which was better.  Of course, those who went along were team players and got promoted, so there was a big motivation to appear to believe whatever guff they were selling.

I was lucky in a way, I managed to find a sinecure where I didn't have to sell my soul to appear to believe in what was obvious crap.  They paid me quite well, and I didn't need to work very hard at all.  I didn't try and create any pretense I was working hard.  I just faded away.

I regret to this day I didn't try something more adventurous for a career, I think I could have done something of some minor consequence somewhere else.  But, it paid well anyway.  And I had kids, they tend to be your priority.

It was my priority in life, trying to, of course I made many mistakes.  I realize now we all do.

I encouraged my kids to major in something they enjoyed and worry about getting a job later.

Several local environmental organizations are sounding the alarm and trying to raise awareness about a power plant proposed for the campus of The Ohio State University.

Officially known as the Combined Heat and Power Plant (CHP), the facility would have a capacity of 105.5 megawatts, power that would be generated – for the first decade of its operation, at the very least – through the burning of natural gas. The plant is proposed for a piece of OSU-owned land at the northeast corner of Tharp Street and Herrick Drive, across the street from the OSU Veterinary Hospital and directly south of the Department of Food Science and Technology.

The building that would hold the facility would be about 60 feet tall, with two cooling towers extending an additional 27 feet above the roof.

The site – which currently holds several green houses – was selected for its proximity to both central campus and the proposed west campus “innovation district,” where early plans call for dozens of new mid-rise buildings and apartments for as many as 4,000 residents. The plant would provide electricity and heating to buildings in both areas, utilizing the heat created by the power-producing turbines to make steam (which is in turn used to heat buildings in the winter and to humidify and regulate temperatures in buildings year-round, and for other tasks in labs and medical facilities).

Also planned for the facility is a new chiller plant, which would be used to cool buildings in the immediate area and in west campus.

Climate Disaster or Step Toward a Carbon-Free Future?
OSU characterizes the new plant as a key component of its latest climate action plan. The stated goal of the plan – which it says is bolstered by the $1.1 billion deal with private energy companies that led to the formation of Ohio State Energy Partners in 2017 – is to achieve full carbon neutrality by 2050. The CHP plant would help achieve this goal by making the university’s heating, cooling and electrical infrastructure much more efficient, and by greatly reducing the need for the institution to draw power from a regional energy grid (run by American Electric Power) that relies heavily on coal and older natural gas plants.

OSU estimates that the CHP plant will cut carbon emissions by 35% in the first year of operations, and is betting that the fuel source of the plant can be transitioned in the not-too-distant-future from natural gas to something more environmentally-friendly – either green hydrogen or renewable natural gas.

Neil Waggoner, the Ohio Senior Campaign Representative of the Sierra Club’s Beyond Coal Campaign, is skeptical of both claims. He points out that the 35% emissions reduction claim assumes that, if the plant is not built, OSU would simply continue to draw power from the regional grid, which he calls a “false choice.” A better method, he argues, would be to take into account other efforts OSU could undertake to transition to a more renewable mix.

For example, OSU could sign more power purchase agreements, like it did in 2012 when the university committed to buying 50 megawatts of power annually for 20 years from Blue Creek Wind Farm in northwest Ohio.

I'd like to understand how I can buy power from some wind farm instead of just taking it off the grid per normal.

Great River Energy said it will test an emerging battery technology that could revolutionize the field of grid-level energy storage by providing up to six days of continuous electricity.

The Maple Grove, Minnesota-based generation and transmission co-op will be the first utility to deploy Form Energy’s novel “aqueous air battery” system.

“If successful, this technology could provide an economically viable option for co-ops and other electric utilities that wish to increase their share of renewable energy on their systems while not sacrificing reliability,” said Jan Ahlen, NRECA energy solutions director.

“Lithium-ion batteries can provide significant grid value, but long-duration energy storage, such as Form Energy’s aqueous air technology, will be critical as states, communities and utilities set ambitious net-zero carbon targets.”

The 1-megawatt grid-connected battery with 150 megawatt-hours of continuous energy capability will be completed by 2023 at the site of Great River Energy’s peaking power plant in Cambridge, Minnesota.

“During the polar vortex in 2019, we experienced temperatures averaging 25 degrees below zero Fahrenheit for a 48-hour period. A four-hour lithium-ion battery would have done very little to help maintain the reliability of the electric grid,” Brekke said.

“A 150-hour battery would make a big difference in an event like that. It would have made a difference even if the polar vortex lasted a few more days.”

At utility-scale, the Form Energy battery also could save a lot of money, Brekke added.

“This system will be a fraction of the cost of lithium-ion battery on a cost-per-MWh basis,” he said.

https://cleantechnica.com/2020/05/11/will-form-energy-aqueous-air-battery-challenge-tesla-for-grid-storage-dominance/

What is an aqueous air battery? No one knows much about the technology and the company is being very tight-lipped about it.

In the discussion to Tina’s article, several people mentioned the power output from the Form Energy battery is quite low. For instance, Troy Frank pointed out the Hornsdale battery in South Australia could supply 1 MW of electricity for 129 hours, so the advantage of the Form Energy battery over a lithium-ion battery may be less than it appears to be at first glance.

He is correct (and the rest of his comments are on point and technically accurate), which leads to this conclusion. Flow batteries like the one coming from Form Energy may become part of the energy storage mix, providing a third option between fast reacting lithium-ion batteries and long term storage from pumped hydro systems. In the end, the issue will come down to cost. As another comment on Tina’s article pointed out, pumped hydro may still be the king of really long term storage but a flow battery can be installed just about anywhere. The same is not true of pumped hydro storage.
