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)

Can any MP ask the government why early treatment kits to stop viral replication & infection are not made available cheaply & prescription free in pharmacies as they are in India? Is it lives we want to save or is it Big Pharma profits? Because the two are mutually exclusive.


There could even be competing kits, & the decision which to take could be left to doctors & patients, as happens with most medicines. The problem is that there is not one of these kits available cheaply & prescription free anywhere in the West.

Doxycycline, Ivermectin, Azithromycin, Hydroxychloroquine, Zinc, Vitamin D, Vitamin C, omega-3s, all approved as safe drugs decades ago. This is clearly not an issue of safety. It should be left to a doctor's experience & judgement whether they are effective or not, not academia.

A GP could simply state on his website: of all the kits I recommend Kit Z, then Kit Y etc. No need to wait hours for consultations, as soon as the symptoms are clear the self administered treatment begins, and thousands of lives are saved, as well as hospitals remain underwhelmed

There is no need to go to ER or ICU if people can buy early treatment kits from pharmacies. There is no need for any hospital to be overwhelmed. This problem could be resolved in days. There is simply no political will to save lives as it means to go against Big Pharma profits.

Now you know I love to sh-t in Harvard. But I also like accuracy. So I decided to go look at Harvard’s catalog to see its lack of military history that this article describes (they only teach history of pets it claims) and what I found shocked me! Shocked me! A thread: 1/


First off, Harvard students literally have multiple sections of military history that they can take listed. (It appears these ones are taught at MIT, so they might have to walk down the street for these) but... 2/


Say they want to stay on campus...they can only take numerous classes on war and diplomacy...3/


They have an entire class on Yalta. That’s right. An entire class on Yalta. 4/


But wait! There is more! They can take the British Empire, The Fall of the Roman Empire for those wanting traditional topics... 5/

In medicine, reckoning with racism includes reappraising the very syntax we use every day. Proud to add my voice w/ @J_Ikeme and @RWGrantMD in this @JAMAInternMed pub addressing:

Does race/ethnicity belong in the first line of the patient

Some background: I’ve struggled with this question since early in medical school

Medical syntax is designed to communicate information in a predictable sequence with key elements prioritized to facilitate efficient communication and formation of an assessment and plan

2/

From preclinical lectures to Qbank questions to clerkship rotations, race/ethnicity was often prioritized in the same sentence as age + gender.

I grew accustomed to reading/hearing: a 70-year-old Black man w/ history of x, a 50-year-old Hispanic woman presented w/ y.

3/

However, when it came time for me to use race/ethnicity, there was always tension. Race/ethnicity are self/socially-ascribed identities that in clinical practice are almost always assumed by providers based on appearance. I was also concerned about the potential for bias

4/

I wondered how my own care would be impacted or not impacted by my ethnicity (Hispanic) – I have light skin so I’m not sure if my doctors would even identify me as such – but how would my care be different if I was presented as a 30-year-old Hispanic male?

Let’s talk about ORGANIC.

Robert Paarlberg’s new book on the food system is out today, and here’s an excerpt.

He’s not a fan of organic, and he makes some good points but misses others.

Here we go.

Organic's biggest shortcoming is that you need more land to grow the same amount of food.

The yield penalty happens in almost every crop, in almost every study.

The gap could narrow with more research/varieties, but it won’t go away.

This has big, bad climate implications.

The second issue I have with organic, which Paarlberg shares, is that its basic criterion is naturalness.

Natural doesn’t mean safe, or even safer. A farming standard based on it forces farmers to sometimes use more dangerous, less effective tools.

On human health, there’s scant evidence that pesticide residues on conventional produce are harmful to consumers (though it’s possible farmworkers could be at risk).

What I don’t want is for folks who can’t afford organic to worry about feeding their kids conventional produce.

On the plus side, Paarlberg acknowledges that the organic standard has some real advantages for animal welfare.

This is why I buy organic animal products.

Many in the organic world would like more regs ensuring animals have decent lives.

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.

The Haas / Force India argument is fascinating, and the decision of the stewards may still have consequences. The first key finding is that the stewards ruled Racing Point Force India to be a valid constructor. That means that it builds its own cars.

Haas had argued that the cars had been designed by Force India, but as Haas knows only too well, "outsourcing" is legal. The stewards decided that "there is no regulatory support for the argument that Outsourcing of Listed Parts cannot come from a former or excluded team."

In determining this, the stewards also came to the following conclusion: "In relation to the submission by the Racing Point Force India F1 Team that it is not a new team, the Stewards decide that the Racing Point Force India F1 Team is indeed a new team."

This will have a big knock on effect for Haas in its continued arguments over the rights of RPFI as relates to its eligibility and rights under the complex payments structure. Haas has argued all along that RPFI should be treated as a new team and tread the same path that it did.

TLDR? Haas lost the fight but may have won the war. In having its argument that Racing Point hadn't designed their own car thrown out, they gained clarification that RPFI was a new team.

हिमालय पर्वत की एक बड़ी पवित्र गुफा थी।उस गुफा के निकट ही गंगा जी बहती थी।एक बार देवर्षि नारद विचरण करते हुए वहां आ पहुंचे।वह परम पवित्र गुफा नारद जी को अत्यंत सुहावनी लगी।वहां का मनोरम प्राकृतिक दृश्य,पर्वत,नदी और वन देख उनके हृदय में श्रीहरि विष्णु की भक्ति अत्यंत बलवती हो उठी।


और देवर्षि नारद वहीं बैठकर तपस्या में लीन हो गए।इन्द्र नारद की तपस्या से घबरा गए।उन्हें हमेशा की तरह अपना सिंहासन व स्वर्ग खोने का डर सताने लगा।इसलिए इन्द्र ने नारद की तपस्या भंग करने के लिए कामदेव को उनके पास भेज दिया।वहां पहुंच कामदेव ने अपनी माया से वसंतऋतु को उत्पन्न कर दिया।


पेड़ और पौधों पर रंग बिरंगे फूल खिल गए और कोयलें कूकने लगी,पक्षी चहकने लगे।शीतल,मंद,सुगंधित और सुहावनी हवा चलने लगी।रंभा आदि अप्सराएं नाचने लगीं ।किन्तु कामदेव की किसी भी माया का नारद पे कोई प्रभाव नहीं पड़ा।तब कामदेव को डर सताने लगा कि कहीं नारद क्रोध में आकर मुझे श्राप न देदें।

जैसे ही नारद ने अपनी आंखें खोली, उसी क्षण कामदेव ने उनसे क्षमा मांगी।नारद मुनि को तनिक भी क्रोध नहीं आया और उन्होने शीघ्र ही कामदेव को क्षमा कर दिया।कामदेव प्रसन्न होकर वहां से चले गए।कामदेव के चले जाने पर देवर्षि के मन में अहंकार आ गया कि मैने कामदेव को हरा दिया।

नारद फिर कैलाश जा पहुंचे और शिवजी को अपनी विजयगाथा सुनाई।शिव समझ गए कि नारद अहंकारी हो गए हैं और अगर ये बात विष्णु जी जान गए तो नारद के लिए अच्छा नहीं होगा।ये सोचकर शिवजी ने नारद को भगवन विष्णु को ये बात बताने के लीए मना किया। परंतु नारद जी को ये बात उचित नहीं लगी।

THE IMPORTANCE OF DEVI BEEJ / BIJA MANTRA.

Once Suutji in his discourse with King Janmajeya repeated the words of Vyasji regarding the pronounciation of the word ऐ. Vyasji had heard the importance of this word in a meeting of all important saints at Naimisharanya.


There this story was discussed.

In that gathering of such great sages, Rishi Jamdagni asked a question to all the eminent luminaries. He wanted to know which diety is the most revered and gets satisfied easily with our prayers. So Lomash rishi replied that Devi

Bhagwati was one such diety. She will be satisfied and is ready to grant you a boon even if you just say the first letter of her beej mantra. In this context he narrated the story of Satyavrat. The story is as follows.

There lived a Brahmin named Devdutt in Kosal.

He was childless. He arranged for an elaborate yagya for a intelligent son to be born. He invited all the eminent rishi's to conduct this Yagya. Rishi Suhotra, Pael, Brahaspati Yagyavalka were assigned different tasks. Rishi Gobhil was asked to sing the Saamved.

He sang the verses very well, but he had to take respite in order to breathe between two verses. This angered devdutt. He spoke his thoughts to Gobhil rishi.

The rishi got very angry as devdutt did not realise the practicalities of singing. He cursed devdutt that

Magudeswarar Temple, Kodumudi
#Erode
#Tamilnadutemples 🚩

Situated on the banks of the river Kaveri, Magudeswarar Temple is one among Paadal Petra Shiva Sthalam. Kshetram is famous Parihara Sthala for Naga Dosham and for performing Tarpanam to the departed souls.


There are 3 sannidhi here for Paramashiva, Mahavishnu and Brahma Deva.

Sthala Puranam says that once Adisesha and Vayu Deva placed Meru parvat at the centre to decide who is stronger among them. Parvatam was held tightly by Adisesha and Vayu blew the wind to push Parvatham.


In this struggle, peak of meru  parvatham broke into 7 pieces and fell in different places as precious gems. Diamond fell at  Kodumudi as Magudeswarar. Panchamirtham abhishekam is very famous here. Vanni tree situated here is very old which contains medicinal values.


It is believed that Agasthiya Muni did Prathishta of Shiva Lingam here. As Adisesha is one of the reason for creation of the temple, this is famous Parihara Sthalam for Naga Dosham. It is believed that those who


who take a bath in the river Kaveri and worship paramashiva and mahavishnu, will be cured of diseases and will get relief from all illness.

RANI NAIKI DEVI AND THE BATTLE OF KASAHRADA

Mohammad Ghori, the young Ghurid Prince conquered Ghaznavids in Afghanistan in the year 1173 CE. He conducted some successful raids into the Indian territory, which even Mahmud Ghazni & the Persians couldn't do.


First&foremost,Ghori invaded states of Multan &Uch in India.After this he turned to southern states of Gujarat &Rajputana.Everybody knows this about Ghori,but what most pple r unaware of is the defeat he suffered at hands of Chalukyan Queen Naiki Devi in 1178 Battle of Kasahrada.


When he marched southwards, his first target was the prosperous fortified town of Anhilwara Patan.
It was the capital of Chalukyas(also known as Solankis of Gujarat) which was established by Vanraj of Chapotkata Dynasty in 8th century.


American historian Tertius Chandler states that it was the 10th largest city in the world at that time. The history of Chalukyas has been written by many historians, but the valour of the Great Queen Naiki Devi remains unsung.


Born to the Kadamba King Paramardin of Goa,Naiki Devi was well trained in sword fighting, horse riding, strategy & every other subject of Statesmanship. She was married to King Ajaypala of Gujarat who sat on throne in 1171CE. Unfortunately,the King died within 4 yrs of his rule.
