The concept of “green” hydrogen energy is increasingly being shattered by reality …

Today, the transition to carbon-free energy is considered to be a resolved issue. The general trend to improve the environmental friendliness of the economic activity of entire countries of the world has become the subject of numerous disputes, discussions and development of strategies for the transition to a new energy structure.

Europe (and the whole world as a whole) has chosen the transition to hydrogen energy as the most economically and energetically effective means of achieving climate neutrality in its countries by 2050.

In the energy strategies presented by Japan, South Korea, Russia and European countries, hydrogen is a universal energy carrier. It is intended to replace hydrocarbon fuels (oil, gas, coal) with an environmentally friendly and neutral gas with a high calorific value.

However, hydrogen energy has a significant problem (in addition to storage and transportation). The lack of free hydrogen deposits. Therefore, hydrogen is required to be produced. That is, to convert primary energy and primary resources into the production of hydrogen.

In other words, we must artificially create this energy carrier, moreover spending more energy on its production than we will receive from its use. And this, in turn, imposes a lot of restrictions on the use of primary energy. Firstly, it must be carbon-neutral, and secondly, powerful enough to provide not only the energy needs of mankind in primary energy, but also have a large reserve for the production of hydrogen and the transition to a hydrogen economy (as seen in Germany). Or to the hydrogen society (according to the Japanese version).

The basic concept for the use of hydrogen in Europe. 
Hydrogen is produced in electrolytic cells using renewable energy sources, as well as coal and gas stations. 
In addition, hydrogen and raw materials for its production (ammonia) are imported. 
The feedstock is processed into an additional volume of hydrogen, which is supplied to consumers through the existing gas pipelines (including together with natural gas).

Primary energy can be obtained in several ways:

  • burning traditional hydrocarbon raw materials (oil, gas, coal);
  • by using the physical processes of fission of an atomic nucleus (atomic energy);
  • using the potential of water masses in places of elevation differences (hydropower);
  • or using wind and solar energy (wind and solar energy);
  • using the thermal energy of the bowels of our planet (geothermal energy);
  • in the future, it is possible to use physical processes of fusion of nuclei of light elements (thermonuclear energy).

Since the hydrogen concept provides for the abandonment of hydrocarbon resources, it is impossible to use gas or coal to produce hydrogen – this will break the entire hydrogen concept.

However, new gas-fired power plants under construction in Germany have practically zero CO2 emissions into the atmosphere due to the technology of capturing associated greenhouse gases with their subsequent utilization. For example, the energy company “Uniper” in Germany has already built the world’s first coal-fired power plant that meets all European environmental standards.

Moreover, in spite of Germany’s policy of not using coal, a brand new 1100 MW Datteln 4 coal-fired power plant was launched in 2020, whose emissions are at the level of the most modern gas-fired power plants operating in Germany. The cost of this project amounted to almost 1.5 billion euros.

Kraftwerk Datteln 4 is the world’s first environmentally friendly coal-fired power plant. 
Germans do things ..

Yes, as amazing as it is, Germany has donated € 1.5 billion to a coal plant! Coal! But an environmentally friendly coal-fired power plant. And this is different – you need to understand.

Obviously, in the next 10 years, gas and even coal-fired power plants will become climate neutral, without harmful emissions into the atmosphere. And this is a fact.

The production of hydrogen as an energy carrier implies the use of renewable environmentally friendly raw materials – water, as well as renewable environmentally friendly sources of energy in the form of the sun, wind and the same hydropower.

The production of hydrogen by this method will be as natural for the Earth’s ecosystem as the water cycle in nature. This type of hydrogen has received the designation – “green”.

Today it is too expensive to mass-produce “green” hydrogen using solar and wind power plants. This trend will only get worse in the future. The thing is that the cost of raw materials in the form of rare earth metals, and just all other non-ferrous metals (for example, copper) is already breaking records due to high demand. Without them it is impossible to build a modern SPP and wind turbine.

Thus, spot prices for polycrystalline silicon increased by more than 20%. And the cost of producing polysilicon panels has grown exponentially since the beginning of 2021!

Therefore, conversations about the mass production of “green” hydrogen, faced with the harsh reality, began to subside on the sly. Simply because producing electricity at the same solar power plants is 3 times more profitable than producing the same amount of “green” hydrogen in energy equivalent.

Today, the production of “blue” hydrogen is 3-4 times more profitable than the production of “green”, even taking into account the carbon tax 

Realizing this, many would-be hydrogen producers have simply abandoned the mass production of green hydrogen. For example, Australia in its hydrogen strategy focuses on the production of “gray” hydrogen from coal with associated storage of CO2. Japan is already interested in the project.

The United Arab Emirates and Qatar will invest in the production of blue hydrogen.

And in the hydrogen strategies of Japan, South Korea and European countries, the point of self-sufficiency of their economies with the necessary amount of hydrogen is generally omitted.

In Germany, it is generally stated that Russia should supply them with hydrogen, so there should be no problems with the transition to a hydrogen economy by 2050 (see paragraph 38 of Germany’s hydrogen strategy).

In Russia, according to the hydrogen strategy, by 2024 the economic model of the hydrogen economy itself, with all its derivatives (production of methane-hydrogen mixtures; production of turbine units capable of operating on hydrogen; production of hydrogen transport) should be developed and substantiated. Gazprom is developing a technology for producing “blue” hydrogen. Rosatom is developing a technology for producing “yellow” hydrogen (electrolysis of water at nuclear power plants and the construction of a nuclear power plant for the direct production of hydrogen by high-temperature electrolysis).

Since 2010, Rosatom has been developing a technology for producing hydrogen using high-temperature gel nuclear reactors. 
The first such station should appear in 2030

Even old Europe is not so optimistic about green hydrogen anymore. Europe suddenly equated the ecological footprint of nuclear power plants in her 387-page study posted on the European Commission’s JRC SCIENCE FOR POLICY REPORT to the ecological footprint of wind and solar power plants.

This is because there is no other way to realize the mass and, most importantly, cheap production of “green” hydrogen, on which Europe relies heavily. Well, this somehow saves the very concept of environmentally friendly hydrogen.

However, in Russia, quite recently, the development of a project began, which is still able to revive the original concept of precisely “green” hydrogen. As the use of water and a renewable environmentally friendly source of energy. This project, worth more than $ 300 billion, will pay off in just 5 years. It will fully provide Europe with the necessary amount of “green” hydrogen. At the same time, Russia itself by 2050 will become the world’s largest producer of hydrogen of all “colors”. And 85% of the total world production of “green” hydrogen will be generated by Russian power plants.

One of the projects for the production of mass and cheap “green” hydrogen is the construction of a tidal power plant in the water area of ​​the Penzhinskaya Bay.

Arms Expo – New submachine gun PPK-20 from Russia

One of the most interesting novelties of the Army-2021 forum was the new version of the PPK-20 submachine gun. It was presented by the Kalashnikov concern. This product is designed in the interests of the aerospace forces. The submachine gun is optimized for use in the equipment of military pilots and should provide their self-defense in emergency situations.

By order of the Ministry of Defense

The development of a promising submachine gun for the armed forces began several years ago. It was carried out within the framework of the Vityaz-MO ROC. The purpose of the work was to create an automatic weapon for a pistol cartridge for use in various structures of the army. Accordingly, it was required to provide high fire performance with limited dimensions and weight.

The first reports on the results of the ROC in the open press refer to the last year. So, in July, the Kalashnikov concern announced the successful completion of state tests. The interdepartmental commission recognized the product as meeting the customer’s requirements and suitable for mass production. It was recommended to assign the name of the new development “Kalashnikov submachine gun mod. 2020 “- in memory of the designer V.M. Kalashnikov, who laid the foundations for a modern line of such weapons.

Updated version of the PPK-20

Modern solutions

PPK-20 in its configuration last year externally significantly differed from the Vityaz-SN. The new version of the weapon for the Aerospace Forces also received a number of components that change its exterior and affect the ease of use.

One of the main requirements of the Aerospace Forces concerned the maximum reduction in the size of the weapon. In this regard, the submachine gun received a telescopic butt, folded by turning forward and to the right. When folded, the PPK-20 with a standard muzzle device has a length of only 410 mm. Unladen weight of the product, without ammunition, scope, etc. – 2.5 kg.

USM both PPK-20 retained the long flag of the fuse-translator of fire, characteristic of the AK. In the new modification, it was supplemented with small levers on the same axis, located on both sides of the weapon. This allows you to engage the safety or select the fire mode without removing the leading hand from the handle.

The weapon received a new forend with strips and slots for mounting the necessary devices. “Last year’s” PPK-20 has a bar only at the bottom, the new one – at the top and bottom. A similar bar is provided on the receiver cover. Mechanical sights are preserved in the front and rear of the forend and cover.

Controls: the standard translator is supplemented with a new lever

The PPK-20 kit includes a silent firing device. If necessary, it is installed directly on the flame arrester using a bayonet connection. This operation takes minimal time, but provides a dramatic reduction in noise and flash.

India will help Russia turn Arctic into global trade route

New Delhi is planning to assist in developing Russia’s Northern Sea Route (NSR). And turning it into an international trade artery, according to Indian Prime Minister Narendra Modi.

“India will help Russia in the development of the Northern Sea Route and opening this route for international trade the same way as Russia helps India to develop with the aim of space exploration and the preparation of the national manned Gaganyaan program,” Modi said, speaking via video link at a plenary session of the Eastern Economic Forum.

The Indian prime minister also said Moscow and New Delhi had managed to make significant progress in developing commercial ties despite massive disruptions caused by the Covid-19 pandemic.

The friendship between India and Russia has stood up against the test of time,” he said.

“Most recently, it was seen in our robust cooperation during the Covid-19 pandemic, including in the area of vaccines. The pandemic has highlighted the importance of the health and pharma sectors in our bilateral cooperation.”

According to the Indian head of state, an energy partnership between the two nations would bring greater stability to the global energy market.

Modi also said that such joint projects as the Chennai-Vladivostok sea corridor, which is currently under development, provide greater connectivity along with the North-South transport corridor.


Major deal on developing Russia’s Big Northern Sea Route sealed at Eastern Economic Forum

A broad agreement aimed at providing stable growth of exports, cabotage and transit traffic along Russia’s Arctic sea route has been signed at the Eastern Economic Forum (EEF) in Vladivostok on Friday.

Russian state nuclear corporation Rosatom and the Ministry for Development of the Far East and the Arctic agreed to closely cooperate on projects aimed at developing the transport artery stretching along Russia’s Arctic coast.

“The Big Northern Sea Route from Murmansk to Vladivostok plays an important role in transport security, and connects by sea the European part of Russia with the Far East,” Rosatom’s director general, Aleksey Likhachev, told the media on the sidelines of the EEF.

“We are interested in promoting cooperation under this project with both Russian and foreign counterparts,” he added.

The Northern Sea Route lies from the Kara Gate Strait in the west to Cape Dezhnev in Chukotka in the east. The Big Northern Sea Route includes the Arkhangelsk, Murmansk regions and St. Petersburg and the Far East from the Northern Sea Route’s border in Chukotka to Vladivostok. The 5,500-kilometer (3,417-mile) lane is the shortest sea passage between Europe and Asia.

The Russian nuclear industry to switch to the development of new civilian power reactors

The license of Rostekhnadzor for the creation of the BREST-OD-300 power unit was issued to the Siberian Chemical Combine of Rosatom (Siberian Chemical Combine, Seversk, Tomsk Region)

Aleksandr Uvarov, editor-in-chief of the information portal on nuclear energy AtomInfo.ru, told RIA Novosti that “Construction of a new reactor is starting in Russia and thus a new,“ land ”direction of reactors with heavy metal coolant is being opened, which is still nowhere in civil nuclear power. has not been mastered in the world ”   He recalled that Russia is the only country with successful experience in operating heavy-metal cooled reactors used on a number of Soviet nuclear submarines.

The power unit with an installed electric capacity of 300 MW with the BREST-OD-300 reactor should become the key object of the experimental demonstration energy complex (ODEC), which is being built at the SGChK site within the framework of the strategic industrial project “Breakthrough”   In addition to the power unit, the ODEC includes a complex for the production of mixed uranium-plutonium nitride nuclear fuel for the BREST-OD-300 reactor, as well as a complex for the reprocessing of spent fuel.

The complex will make it possible to create a closed on-site nuclear fuel cycle, which will make it possible not only to generate electricity, but also to prepare new fuel from the fuel discharged from the reactor core. Earlier it was reported that the launch of the BREST-OD-300 reactor is scheduled for 2026. The BREST-OD-300 reactor is intended for practical confirmation of the main technical solutions laid down in lead-cooled reactor plants in a closed nuclear fuel cycle, and the main provisions of the inherent safety concept on which these decisions are based.

The features of the reactor make it possible to abandon large volumes of containment, a melt trap, a large volume of support systems, and also to reduce the safety class of non-reactor equipment.   Lead coolant has a number of advantages. First, it slows down neutrons a little, which is fundamentally important for the operation of “fast” reactors. In addition, lead has a high boiling point (about 1.8 thousand degrees Celsius), it is chemically inert in contact with water and air, and does not require high pressure in the coolant circuit.  

The combination of the properties of a heavy lead coolant and dense heat-conducting nitride fuel creates conditions for achieving full reproduction of nuclear “fuel” and excludes the most severe accidents – with an uncontrolled increase in power (as in Chernobyl) and loss of heat removal from the reactor core (as in Fukushima). This is the essence of the natural safety of the BREST-OD-300 reactor.   The integral design of the reactor plant makes it possible to localize coolant leaks in the reactor vessel volume and to exclude the dehydration of the core.

This excludes accidents requiring the evacuation of the population, and this actually means that the radiation safety of the environment is guaranteed not by technical means and methods, but by the very absence of activity above the already existing natural levels.

Why Rosatom’s new laid-down reactor is the safest in the world, and when will it enter series

Russian giant Rosatom is rightfully considered the world leader in nuclear energy and a number of other high-tech areas, as evidenced by an extensive portfolio of foreign orders

Rosatom was the first to master the serial production of the latest modern third generation fast breeder reactors. 

Now our concern has begun construction of the world’s first power unit of the next generation – the fourth.

A new power unit is being built in the city of Seversk in the Tomsk region. 

The installation was named Brest OD 300.

The new reactor operates on fast neutrons and has a lead coolant.

Rosatom considers this # type of reactor to be completely safe. Accidents like Chernobyl and the Fukushima disaster using the Brest reactor are excluded.

The new reactor was based on the principle of natural safety. 

Foreign competitors of Rosatom do not possess such technology and continue to build thermal neutron reactors in which water serves as a coolant.

The advantage of fast reactors is the ability to reuse spent nuclear fuel as new fuel, thereby achieving a closed cycle. 

In addition to being economical, fast reactors are safer than existing thermal reactors. The possibility of unpredictable and uncontrollable acceleration of neutrons is excluded, which is equivalent to the loss of the coolant. 

The risk of a parazirconium reaction that provoked the disaster at the Fukushima nuclear power plant is also excluded. 

The work on the design of the fourth generation reactor has been carried out by Rosatom since 2010. Rosatom plans to commission the Brest power unit by the end of 2025.

One of the important advantages of the new reactor will be its ability to run on fuel # uranium 238, which is much cheaper and more widespread on our planet, in contrast to the rare uranium 235.

In the next few years, Rosatom plans to organize the serial production of the newest Brest reactors in Russia, and after 2030 start exporting them to foreign partners. 

“KamAZ of Doomsday, the conqueror of the poles…

You all know such tractors and trucks as KamAZ. They can be found on the streets of absolutely any city, on the highway, or even in villages. But what do we usually see? These are trucks, well, dump trucks. But what if I tell you that KamAZ has an incredible truck capable of driving anywhere in general, of unrealistic dimensions and many functions, as well as with incredible design solutions? Today I will tell you about the coolest, largest and most expensive KamAZ – KamAZ-e “Arctic”!

In fact, no matter what work of art “Arctic” may seem. During the premiere, it did not make a splash. “How so ?!” – you ask. The answer is further in the article!


Creature

For the first time, the idea to make such a “miracle” came from a designer from Naberezhnye Chelny in 2017 and they embodied it in the form of KamAZ 6345 (in the photo on the left). However, it had to be improved and almost completely changed, and in the course of this, “Arctic” appeared. And when it was presented at the “COMTRANS19” exhibition, everyone thought it was just an improved 6345! However, if the old “Arctic” had a 6×6 base, the old cockpit. Then when everyone realized what KamAZ had done, then all the youth clambered over this car and just the same a sensation took place!

KamAZ 6345 (Left) and KamAZ 6455 (right, the same new Arctic) Photo taken from the site gruzovikpress.ru

Appearance

Agree that the appearance of this truck is something absolutely unusual and indescribable. This is a real doomsday machine. High ground clearance, unusual design, a bunch of ladders and equipment and the most unusual thing – wheels! It is also very unusual to watch him turn, but more on that later.

At the driver

This is how the workplace of the driver of this “miracle” looks like. But in order to drive such a truck, you need to be a real extreme, or a complete professional in your field.

Despite the abundance of functions and the unusualness of this truck, the driver will not be confused in the cab: everything is intuitive and simple, especially for those who have already driven KamAZ-ah. As you may have noticed, there is an automatic transmission here, because poking around with a “handle” on such a car would not be the best thing to do. Naturally, even a sleeping bag is provided here!

For what

I think that by the very name of this tractor, you have already understood what it was created for. The word “arctic” speaks for itself! But it was made not only for the conquest of the poles. It is provided for and created for hard-to-reach terrain, where there is no road from the word “at all”;
for wetlands where conventional trucks cannot pass; and the list of what it was prepared for includes tundra, taiga, permafrost.

Constructive decisions

Naturally, the most important and unusual solution, one might even say a design temptation, is the articulated frame, which is movable in the horizontal plane and provides a minimum turning radius. The maximum folding angle, by the way, is 45 degrees!

Technical specifications

Below, instead of a ton of text, I will give photographs of the size of the “Arctic” 8×8 and a small list of its technical characteristics:

Here is such an article! By the way, the price of this miracle starts at 15 million rubles! What do you think about this truck? Personally, I don’t even know how to summarize

A hydrogen economy is closer than you think

Shell, BP and Saudi Aramco are all actively exploring ways to transition to a hydrogen-mixed economy

By JOHN BALLANTINE

Hydrogen-mixed economy might be coming much sooner than expected. There are many factors contributing to that outcome – at least at the middle term of transition from fossil fuels to renewable energy sources.

Tehran, 1943: Joseph Stalin, Franklin D. Roosevelt and Winston Churchill. Hosted by the young Shah Reza Pahlavi. Agree on plans for the two-front attack on Hitler while sketching out the east-west division of Europe.

Holding the meeting in Iran, with separate consultations with the shah, was no mistake. Gulf oil was a critical resource to the Allied war effort. Oil has flowed under the surface of political conflicts ever since.

Fast-forward to today, and political antagonists and energy players are again forging a messy path forward. This time focused on long-term energy transitions as disparate countries try to slow and eventually stop climate change.

The 2015 Paris Agreement was a groundbreaking diplomatic effort. 196 countries committed to prevent average temperatures from rising by more than 2 C (3.6 F), with an aim of less than 1.5 C (2.7 F). To meet that goal, scientists argue that fossil fuel use will have to reach net-zero emissions by mid-century.

As the world’s population and economies grow, energy demand is expected to increase by as much as 50% over the next 30 years. Making the right long-term investments is crucial.

Different visions of the future

Energy companies and policymakers have widely different visions of that future. Their long-term scenarios show that most expect fossil fuel demand to remain steady for decades and possibly decline. However, many are also increasing their investments in cleaner technologies.

The International Energy Agency has a history of underestimating demand and clean energy. Forecasts that renewable energy will meet about one-third of the global energy demand by 2040 in its most optimistic scenario.

That would be in a world with higher carbon taxes and more wind power, solar power, electric vehicles, carbon capture and storage. Greener technologies may come close to keeping warming under 2 C, but not quite.

Exxon, on the other hand, forecasts a path dependent on a fossil fuel-based economy, with slower transitions to electric vehicles, steady demand for oil and gas, and a warmer world.

Exxon is also investing in carbon capture and storage and hydrogen. However, it believes oil and gas will provide half the global energy supply in 2040 and renewable energy will be less than one-fifth.

OPEC, whose members are among the most exposed to climate change and dependent upon oil and gas, also sees oil and gas dominating in the future. Nonetheless, several Gulf nations are also investing heavily in alternative technologies. – including nuclear, solar, wind and hydrogen.

BP proposes a more focused shift toward cleaner energy. Its “rapid scenario” forecasts flat energy demand and a more dramatic swing to renewables combined with a growing hydrogen economy. The company expects its own renewable energy to go from 2.5 gigawatts in 2019 to 50 GW by 2030. And it expect its oil production to fall by 40%.

Exploring hydrogen’s potential

Others are also exploring hydrogen’s potential. Much as with utilities’ shift from coal to natural gas, hydrogen may ease the transition to cleaner energy with enough investment.

Since this fuel is getting so much industry attention, let’s look more closely at its potential.

Hydrogen has the potential to fuel cars, buses and airplanes. It can heat buildings and serve as a base energy source to balance wind and solar power in our grids. Germany sees it as a potential substitute for hard-coal coke in making steel.

It also offers energy companies a future market using processes they know. It can be liquefied, stored, and transported through existing pipelines and LNG ships, with some modifications.

So far, however, hydrogen is not widely used as a clean-energy solution. First, it requires an upfront investment – including carbon capture capacity. It requires pipeline modifications, industrial boilers for heat rather than gas, and fuel cells for transportation. Plus policies that support the transition.

Second, for hydrogen to be “green,” the electricity grid has to have zero emissions.

Most of today’s hydrogen is made from natural gas and is known as “grey hydrogen.” It is produced using high-temperature steam to split hydrogen from carbon atoms into methane. Unless the separated carbon dioxide is stored or used, grey hydrogen results in the same amount of climate-warming CO2 as natural gas.

The hydrogen market is divided into grey, blue and green fields depending on how the fuel is produced. Image: Facebook

Gray, Blue and Green Hydrogen

“Blue hydrogen” uses the same process but captures the carbon dioxide and stores it so only around 10% of the CO2 is released into the atmosphere. “Green hydrogen” is produced using renewable electricity and electrolysis. It is twice as expensive as blue and dependent on the cost of electricity and available water.

Many electric utilities and energy companies, including Shell, BP and Saudi Aramco, are actively exploring a transition to a hydrogen-mixed economy, with a focus on blue hydrogen as an interim step.

Europe, with its dependence on imported natural gas and higher electricity costs, is setting ambitious net-zero energy targets. That will incorporate a mix of blue and green hydrogen coupled with wind, solar, nuclear and an integrated energy grid.

China, the world’s largest energy user and greenhouse gas emitter, is instead investing heavily in natural gas. Natural gas has about half the carbon dioxide emissions of coal – along with carbon capture and storage and a growing mix of solar and wind power.

Russia, the second-largest natural gas producer after the US, is expanding its gas production and exports to Asia. Some of that gas may end up as blue hydrogen.

Ramping up blue and green hydrogen as clean-energy solutions will require substantial investments and long-term modifications to energy infrastructure. In my view, it is not the magic bullet, but it may be an important step.
