No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.

👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em

 The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)
We see strong demand for hydrogen from steel in particular as producers all over Europe (🇸🇪🇷🇴🇩🇪🇦🇹🇮🇹🇫🇷) plan to move to direct reduced iron (DRI) processes – and so do others around the globe, as recent announcements from China and Korea have shown. (6/17)
Given the 2050 climate neutrality target, we see the demand from refineries vanish, to be replaced with demand from steel. Overall, by 2050 we expect that almost 300 TWh of low-carbon hydrogen will be required. Remarkably, that is similar to hydrogen demand in 2020. (7/17)
Having established inescapable demand, we can start thinking about matching supply. European and neighbouring countries have a high renewable energy potential that can be tapped for direct-electric applications and renewable hydrogen production. (8/17)
In our analysis, we consider two scenarios with renewable hydrogen production: The BLUE-GREEN scenario also includes SMRCCS as an option in 🇳🇱🇳🇴🇬🇧because those countries are actively developing the technology. (9/17)
Taking into account asset lifecycles and political commitments in the BLUE-GREEN scenario, fossil-based hydrogen with carbon capture will remain a viable investment until the 2030s. However, … (10/17)
… strong policies for renewable hydrogen will shorten the investment window for fossil hydrogen, likely closing it before the end of the 2020s as is the outcome of the FAST GREEN scenario which is in line with EU Hydrogen strategy electrolyser targets. (11/17)
But producing the required quantities of H2, especially with renewables, is only one piece of the puzzle. Geography adds to the challenge: steel, ammonia, refineries and chemical plants are widely distributed across Europe. Their demand can vary by an order of magnitude. (12/17)
Ensuring reliable supply means accounting for various weather and seasonal effects. In our analysis, we model salt caverns to take care of the variation in renewables to produce “flat hydrogen”. That led us to derive least-cost pipeline corridors for hydrogen transport. (13/17)
Consequently, we identify 4 robust no-regret corridors for early hydrogen pipelines and storage based on industrial demand in different parts of Europe. The demand identified is unlikely to justify a large, pan-European H2 backbone. (14/17)
We do note, however, that our assumptions are limited to inescapable demand from industry. Adding potential hydrogen demand from power, aviation and shipping sectors is likely to strengthen the case for a more expansive network of H2 pipelines. (15/17)
Nonetheless, even under most optimistic scenarios any future H2 network will be smaller than the current natgas network. A no-regret vision for H2 infrastructure reduces the risk of oversizing by focusing on inescapable demand, robust green hydrogen corridors and storage. (16/17)

I think @SamAdlerBell in his quest to be the contrarian on Fauci gets several things wrong here. 1/


First, the failure last year actually was driven by the White House, the #Trump inner circle. Watch what's happening now, the US' scientific and public health infrastructure is creaking back to life. 2/

I think Sam underestimates the decimation of many of our health agencies over the past four years and the establishment of ideological control over them during the pandemic. 3/

I also am puzzled why Tony gets the blame for not speaking up, etc. Robert Redfield, Brett Giroir, Deb Birx, Jerome Adams, Alex Azar all could have done the same. 4/

Several of these people Bob Redfield, Brett Giroir, Alex Azar were led by craven ambition, Jerome Adams by cowardice, but I do think Deb Birx and Tony tried as institutionalists, insiders to make a difference. 5/

A week ago I voluntarily admitted myself to the hospital to get help bc I am losing weight as a result of increased food intolerances, secondary to my very severe #MECFS. A psychiatrist here decided that im mentally ill, 1/

purely on the basis that the medical workup was unable to explain my food intolerance. My psych eval only found mild anxiety and depression. 2/

They have put me on a 72hr psych hold while they work to get the county courts to commit me to a psych ward. This is a nightmare. They have taken away most of my belongings, put me in a new uniform, and are keeping me under 24/7 video surveillance. 3/

In the middle of the night last night when I sat up to use the urinal loud alarms sounded, as though I was trying to escape. I can’t even walk and hadn’t even left my bed. 4/

If they succeed in having me fully committed I will lose ability to communicate with the outside world except for an occasional phone call. I will lose all agency, and will very likely have treatments forced upon me. 5/

If you want to get in the best shape of your life by 2023 read this:

1. Get 80-90% of your calories from single ingredient nutrient dense foods.

2. Avoid processed foods as much as possible because they're addictive, devoid of nutrients & leave you feeling empty.

3. Eating similar meals every day is an underrated way to get lean.

4. Lift weights 2-4x a week. Use progressive overload to build muscle.

5. Progressive overload is simply doing more through reps, weight or frequency,

6. Eat .8 to 1 gram of protein per pound of body weight. This helps you build & retain muscle. Eat protein with every meal.

7. Avoid trying to lose weight. Focus on creating good habits. The first is focused on an outcome the latter is focused on your lifestyle.

8. Your aim is to become the type of person who stays in shape. In order to change your body your identity must come along for the journey.

9. Eat your meals on a schedule. This will help train your hunger & circadian rhythms.

10. Replace snacking with water & drink it before meals. You usually want to snack because you're bored or dehydrated. Water also helps you feel full & increases energy.

Living with meltdowns.

A personal, very late diagnosed, autistic perspective.

#autism
#AllAutistics
#ActuallyAutistic

1/

Before my autism diagnosis I had occasional emotional outbursts. These generally happened at home after a sustained period of pressure at school or at work.

When I discovered I was autistic I realised that these were actually what people call meltdowns.

2/

Getting intensely upset was a bit of a family thing. Sudden shouting and throwing of things, with resumption of peace and calm afterwards, wasn’t that unusual.

In fact we had a kind of mantra that it was much better to express our emotions than to keep them bottled up.

3/

It was hard to gauge my own emotions against other people’s but by any measure I felt things incredibly intensely.

As a child the injustice of being told off for something that wasn’t my fault burned into me. I sobbed until the tears stang my face and I could hardly breathe.

4/

But suppressing emotion was necessary for me to survive in the outside world. That’s partly what led to uncontrolled outbursts of feelings at home.

I melted down because there was no justice and I’d been misunderstood. I wasn’t using emotion as some kind of bargaining tool.

Ever notice how the top niches are centered around health, wealth, and relationships?

There's a deep-rooted psychological (and biological) reason why.

And today, I'm gonna to explain all of it so you can start profiting off of this knowledge 💰💰

*Now, this thread is going to be long and in depth. Make sure to favorite the top tweet now so you can come back to it later.

So. Down to the very core of every living being (humans, dolphins, bacteria, aliens), there are only two drivers:
1. To survive
2. To reproduce

Right off the bat, we know that sex is a primary driver to human behavior.

This would also mean that each gender has its own insecurities regarding sex.

Men have a subconscious fear that their woman will leave them for someone more successful

Women have a fear that their man will leave them for someone younger & better-looking

We can conclude that men are attracted to looks, and women are attracted to status.

This is human nature down to its very core.

Crazy, blue-haired feminists will try to argue and say otherwise.

But, 50 years of feminism DOES NOT OVERRIDE millions of years of evolutionary biology.

Here's a quick visualization exercise so you can see how true all this is...

Spent a quaint half hour in a cafe listening to a guy yell at his dad after his dad said that the women Trump molested wanted it: "Dad, that's like saying the Jews who died in the Holocaust were asking for it!" ENJOY YOUR TERRIBLE FAMILIES THIS WEEK!

"Mom, has a man ever touched you without your consent?"
"Of course."
"Did you report it?"
"No."
"Dad, your WIFE has been through this!"

Dad was unmoved and told the guy to stop arguing with him.

At this point we learned the boy child has allergies.

I forgot to remark upon the presence of the very cute grandson, who was very small and gave not one shit about the yelling. I believe a sister or aunt was present and feeling very stressed. I wanted to hand her a Xanax or seven.

It was really hard to not jump in and say, "Sounds like you guys are going to have a fun meal tomorrow!" so they could unite in hatred against me, the outsider, and stop squabbling. Instead I exchanged glances with a nearby fellow lady patron, who also emotionally ate a cookie.

Anyway, I want to thank the random family for yelling about rape and the Holocaust in an Israeli cafe in the US of A today because it reminded me that while this country isn't the greatest, it is inevitably my stupid favorite and I am never, ever bored.

1. The major problem most startups face is marketing and the ability to carve out a niche, find and retain paying customers.

Even with a stellar developer team and a stellar product, your startup may not grow or survive without a great marketing and sales teams.

2. Start growing your audience before you’ve a product or an idea.

You should start promoting yourself and building your audience before you have a finished product or even before you have a great idea that you want to build.

3. Don’t wait to start building your audience after you’ve launched a product.

Most first-time developers actually ignore marketing.

They’re oblivious to the challenge of attracting people to take a look at something they’ve created.

4. At least until they see their first project crash and burn within hours of the launch.

There are so many times that I have seen developers spend countless hours building something, releasing it with no fanfare...

5. and only then trying to figure out how to promote it by asking marketing questions on Indie Hackers, Quora or Hacker News. Don’t make that mistake.

#DoYouKnow -The place where
Lalitha Sahasranamam -1000 names of Devi originated.

It is in Lalithambigai temple -Thirumeeyachur,Near Mayiladuthurai,TN

There is a Legend #story & it is related to this beautiful #sculpture of Kshetrapuraneswarar & Ambal Lalithambigai #Thread 👇


#Legend #story
It is believed that this is birth place of Kashyapa Maharishi’s sons, Arunan& Garudan. Arunan(charioteer of Surya)was physically handicapped.He was a Shiva devotee.Arunan wanted to visit Kailash to have Shiva Darshan,but Surya Dev denied permission.

So Arunan disguised as a girl & was on his way to Kailash.On the way Surya Dev saw this girl & outraged her modesty.Shiva was very angry with Suryan for misbehaviour & cursed him to get darkened. Whole world plunged into darkness.Surya Dev pleaded to Bhagwan Shiv to forgive him.

Shiva Bhagwan asked him to go to Thirumiyachur & worship him there. As advised, Surya Dev performed rigorous penance, placed murthi of Shiva& Parvathy on an elephant & took them to the clouds.Shiva in this temple is known as Meganathaswamy,Devi is known as Lalithambigai


Even after severe penance,Shiva does appear,so Surya Dev cries out in agony.Disturbed by his call, Parvathy protests.Siva pacifies her & offers relief to Surya Dev.The sculpture of Shiva pacifying Ambal shows her sullen from one angle &smiling from another.

Hey, for people interested in this stuff, here's a thread about a change we made to running our facebook account:

So, about 5 years ago, we got on facebook. Why? Well, facebook has a big audience and they like to consume on facebook. So, we started posting comics there, even though we got paid nothing and facebook made money off the free content.

Why? Because back then, once in a while, you would say "also hey, I sell books" or "hey, I'm going to be signing at this event" and your facebook followers would actually see it.

Effectively, the implicit old arrangement was "facebook lets me reach readers efficiently, and I supply facebook with free content they run ads on."

Over time, like a bad business partner, facebook basically made it impossible to reach your audience without *paying them*. Thus, you supply them free content on which they run ads, and you get nothing in exchange.
