  • Retragerea ArcelorMittal pune sub semnul întrebării oțelul verde german

    Retragerea ArcelorMittal pune sub semnul întrebării oțelul verde german

    As Germany has pledged to become carbon-neutral by 2045 — five years earlier than the rest of the European Union — the steel industry must cut up to 55 million metric tons of CO₂ annually, which is roughly 30% of all industrial emissions, according to the German Steel Federation lobby group.

    In order to make German steel production significantly more sustainable, the previous government comprising the Social Democrats, the environmentalist Greens and the pro-business FDP had embarked on policies encouraging the use of hydrogen with huge state subsidies.

    Green hydrogen produced with renewable energy is planned to replace coal in the industry.

    Why ArcelorMittal pulled plans for green steel in Germany

    One of the steelmakers who had initially applied for government subsidies was Luxembourg-based steel conglomerate ArcelorMittal, under a corporate plan that intended to make the company’s two German steel works carbon-neutral by 2050.

    The German government supported the plan, offering €1.3 billion (that the European steel market is currently under “unprecedented pressure, with weak demand and high levels of imports.”

    Billions in subsidies likely not enough

    The pullout of ArcelorMittal from the German green steel plan highlights the risk for companies to fully embark on a green transition course.

    The €1.3 billion in German state money were primarily intended to cover the massive upfront costs of building new production facilities. But that’s only part of the problem.

    Using green hydrogen in steel production — produced by the electrolysis of water, using renewable electricity mainly from wind and sun —  is still more expensive than grey hydrogen based on natural gas or coking coal.

    Yet, green steel must ultimately compete on global markets with cheaper, conventionally produced steel. And while changes in global coal prices affect all steelmakers equally, says Stefan Lechtenböhmer, switching to hydrogen-based production means “entering a completely different market.”

    “Hydrogen is produced locally, and long-distance transport is still very difficult today,” the professor at the University of Kassel in Germany told DW, adding that green hydrogen requires large amounts of electricity, meaning that local power prices directly impact its cost.

    Germany’s hydrogen target a pie in the sky?

    But the issue isn’t just cost; supply is also a major challenge. German steelmakers will need a reliable and sufficient supply of green hydrogen, a portion of which is supposed to be produced domestically.

    According to Germany’s National Hydrogen Strategy, the country aims to build up 10 gigawatts (GW) of electrolyzer capacity by 2030 to produce green hydrogen.

    But that target appears to be wishful thinking, because as of February 2024, Germany had just 0.066 GW of installed electrolyzer capacity, data from the government’s Energy Transition Monitoring Report shows.

    “It’s almost impossible to meet the 2030 target now,” Martin Wietschel, energy expert at the Fraunhofer Institute for Systems and Innovation Research, told German ARD public television recently.

    Hydrogen imports essential but inefficient

    Energy experts agree that most of the hydrogen Germany needs will have to be imported from other countries, which is why the government has revised its strategy, now assuming that between 50% and 70% of the projected 2030 demand will have to be sourced from abroad.

    Berlin is now working to make sure that both foreign production capacity and extensive transport infrastructure will be in place by then.

    At the European Union level, a range of hydrogen infrastructure projects are in the pipeline to be completed by 2030 — including repurposing natural gas pipelines to carry hydrogen and constructing entirely new ones.

    Here, too, progress is hampered by setbacks. Several pipeline projects, for example, have been canceled or delayed, including a North Sea pipeline to Germany planned by Norway’s Equinor, and a pipeline from Denmark.

    At the same time, shipping hydrogen across oceans is also not yet viable on a large scale. Hydrogen must be liquefied for ship transportation in a process that requires cooling it to minus 253 degrees Celsius (minus 423 degrees Fahrenheit).

    Alternatively, it can be converted into ammonia for transport, but that would lead to energy losses of around 50%, says Lechtenböhmer.

    As a result, transportation costs would cancel out the cost advantages of wind- or sun-rich countries like Namibia, Chile, or Australia, the expert added, which were touted as promising green hydrogen partners for Germany.

    Some steelmakers stay the course

    Given the soaring costs and sluggish investments on both the supply and demand sides, a study by the Institute of Energy Economics (EWI) at the University of Cologne, Germany, doubts the EU’s and Germany’s 2030 goals for green steel are still achievable.

    But despite the challenges, ArcelorMittal is not abandoning green steel altogether — it’s just shifting production to countries with more predictable and affordable electricity supplies.

    In May, the company announced that it will build its first new electric arc furnaces (EAFs) in Dunkirk, France, — one of the countries that are “able to provide visibility and certainty on low-cost electricity.”

    The current electricity prices in Germany, the statement added, are high when compared internationally and with European neighbors. 

    Hold out and wait for EU carbon market

    By contrast, German steelmakers Thyssenkrupp and Salzgitter AG say they remain committed to Germany as the location for producing green steel.

    Following ArcelorMittal’s pullback, both companies, however, called for faster infrastructure development and better safeguards for competitive energy prices.

    Unlike ArcelorMittal, which owns steelworks all over the world, the two companies’ operations are solely based in Germany, lacking the flexibility to relocate production abroad.

    Public procurement could help them, particularly as the current government plans to spend massively on revamping German infrastructure under a multi-billion-euro investment plan.

    That money could also be used to support green steel production, Lechtenböhmer argues, but the government must be “willing to pay higher prices for green steel.”

    In the long run, steel prices in Europe — whether conventional or green — are likely to rise due to a new EU emissions trading system coming into force in 2027.

    At the moment, says Lechtenböhmer, most industrial companies have received their emissions allowances for free. But the EU’s new scheme will introduce a carbon market that will likely boost prices for coal-based steel compared with green steel.

    A study by the Boston Consulting Group projects that conventional steel will no longer be economically viable in Europe after 2030.

  • Atacurile americane asupra instalațiilor nucleare iraniene amplifică temerile legate de siguranță.

    Atacurile americane asupra instalațiilor nucleare iraniene amplifică temerile legate de siguranță.

    The strikes were a part of what US President Donald Trump called “Operation Midnight Hammer” and targeted the nuclear facilities in the cities of Fordo, Natanz and Isfahan.

    The operation involved 125 aircraft and specialty B-2 bombers carrying 30,000-pound bombs officially designated as Massive Ordinance Penetrators — and colloquially known as “bunker busters.”

    Fordo heavily fortified

    The strike in Fordo was the most significant. It is the country’s most heavily fortified nuclear facility buried deep inside a mountain to shield it from attacks.

    It is unclear when Iran began building the plant in Fordo but its existence was revealed to the world in 2009. The facility was designed to house around 3,000 centrifuges, machines used to enrich uranium.

    How Iran’s economy suffers from war with Israel

    As part of Iran’s 2015 nuclear deal — the Joint Comprehensive Plan of Action (JCPOA) — with global powers, Tehran agreed to convert the site into a research facility and halt uranium enrichment there for 15 years.

    But after US President Donald Trump, during his first term, unilaterally withdrew from the agreement in 2018, Iran resumed enrichment activity at Fordo.

    Iran has been enriching uranium to 60% purity at the site, well beyond what is required for civilian nuclear power generation purposes. Tehran also announced plans to further expand enrichment capacity at the site.

    The International Atomic Energy Agency (IAEA )also said it had found uranium particles at Fordo enriched to as high as 83.7% purity — significantly close to the 90% enrichment needed for weapons-grade uranium.

    Targeting uranium enrichment facilities

    Another target of the US operation was the nuclear facility in Natanz, Iran’s largest uranium enrichment hub, located around 140 miles (225 kilometers) south of Tehran. 

    Like the one in Fordo, Natanz is also a subterranean nuclear site that can hold around 50,000 centrifuges.

    Both the Fordo and Natanz facilities had previously been targeted multiple times in a series of sophisticated attacks.

    Iranian officials said these attacks — ranging from the 2010 Stuxnet cyberattack to incidents disabling the Fordo power grid and a remote-controlled explosion in Natanz four years ago — had already caused extensive destruction and severely damaged their enrichment capabilities.

    The third nuclear site targeted by the US was the one in Isfahan, which was suspected of hosting near weapons-grade nuclear fuel.

    In simple terms, this facility was converting natural uranium into uranium hexafluoride gas, which goes into centrifuges at Natanz and Fordo for uranium enrichment.

    Russia provides fuel for Iran’s sole nuclear power plant

    The sites at Fordo, Natanz and Isfahan are uranium enrichment facilities, and experts estimate that Iran already has more than 400 kilograms (880 pounds) of highly enriched uranium. 

    Despite the damage US strikes caused to the three sites, the fate of this enriched uranium remains uncertain.

    Iranian government sources mostly claim that the enriched uranium has been moved to “secure” locations.

    However, several media outlets have quoted Israeli sources as saying that the uranium was distributed among the three sites and “was not relocated.”

    A senior Israeli official, who did not want to be named, recently told the BBC that a portion of the enriched uranium was located deep within the Isfahan facility and that Iran could try to retrieve it.

    The three targeted sites are believed not to have active nuclear reactors. However, Iran does have an operating nuclear power plant, in Bushehr, some 750 kilometer south of Tehran. The plant, which is monitored by the IAEA, is run by uranium supplied by Russia. Its spent fuel is also returned to Russia to prevent reprocessing into weapons-grade material.

    The plant was not targeted in the US strikes.

    Monitoring radiation levels in Iran

    Following the US attacks, the IAEA said it didn’t notice any increase in radiation levels in the region.

    As no active reactors were targeted, the potential risk of radiation is limited to leakage of the uranium hexafluoride gas from enriched uranium storage tanks, centrifuge cascades or pipelines.

    If released, the gas would react with moisture in the air to form uranyl fluoride and hydrofluoric acid, the latter being a highly corrosive and dangerous acid.

    Contact with this acid or inhalation of its vapors can destroy lung tissue, and cause severe and deadly respiratory problems, which could result in suffocation and death.

    “There are indeed indications that uranium hexafluoride was released at the facility site. Both radiological hazards and elevated radiation levels, as well as chemical dangers, were mentioned. This can only refer to the release of hydrofluoric acid,” Clemens Walther, professor and nuclear expert at the Institute for Radioecology and Radiation Protection at the University of Hanover, told DW.

    “However, it was clearly stated that the incident was confined to the site itself. No spread into residential areas has been reported.”

    Roland Wolff, an expert in radiation protection, medical and radiation physics, said uranium, as a heavy metal, is chemically toxic.

    “It can, for example, cause kidney damage. Incorporation increases the risk of cancer as well as the risk of genetic damage due to the short-range alpha radiation. Depending on the scenario, this presents a potential hazard for both workers and the general population,” he told DW.

    How much damage was done to Iran’s nuclear program?

    Risk of a Chernobyl-style disaster?

    The nuclear meltdowns in Chernobyl in 1986, and Fukushima in 2011, highlighted the radiation risks caused by reactor accidents.

    The Fukushima disaster occurred when a magnitude 9 earthquake and tsunami disabled the power supply and cooling systems of three reactors at the Fukushima Daiichi nuclear power plant, on Japan’s east coast.

    Radioactive material was released from the site, leading to tens of thousands of people being evacuated.

    But Wolff said the targeted sites don’t pose a Chernobyl-style danger.

    “The radioactive inventory in enrichment facilities, unlike in nuclear reactors, does not contain fission products,” said the radiation expert. “Furthermore, it was not released into high altitudes by an explosion, as was the case in Chernobyl. Therefore, potential contamination is assumed to be local.”

  • Operațiunea Valkyrie: 81 de ani de la complotul de asasinare a lui Hitler

    Operațiunea Valkyrie: 81 de ani de la complotul de asasinare a lui Hitler

    „Nu mai rămâne nimic altceva decât să-l ucidem”, le spusese el celor mai apropiați confidenți cu câteva zile mai devreme.

    Stauffenberg nu a fost doar asasinul, ci și cel mai important organizator al unei tentative de lovitură de stat la scară largă, comisă de persoane din cercurile conservatoare, printre care se numărau înalți oficiali militari, diplomatici și administrativi.

    Claus Graf Schenk von Stauffenberg (1907-1944)Imagine: picture-alliance/akg-images

    Cu puțin timp înainte ca bomba cu ceas să explodeze pe 20 iulie 1944, ofițerul părăsise cazarma. A zburat cu un avion militar spre Berlin, crezând că „Führerul” era mort. În capitala Germaniei, „Operațiunea Valkyrie” era în desfășurare.

    Inițial concepută ca un plan al Wehrmacht-ului pentru a suprima o posibilă revoltă, conspiratorii – care dețineau poziții cheie în întregul aparat de stat nazist – doreau să o reutilizeze pe „Valkyrie” pentru propria lor lovitură de stat.

    Condamnată eșecului

    Dar Hitler a suferit doar răni minore. Masa grea de stejar și faptul că ferestrele cazărmii erau larg deschise din cauza vremii caniculare au atenuat forța exploziei.

    În ciuda acestui fapt, șansa unei lovituri de stat nu ar fi fost încă complet pierdută – dacă toți cei implicați ar fi dus la bun sfârșit Operațiunea Valkyrie fără abatere. Dar au existat întârzieri, defecțiuni și o planificare insuficientă. În plus, confruntându-se cu presiunea enormă de a fi descoperiți, unii dintre cei implicați au rămas pasivi sau chiar și-au schimbat tabăra.

    Spre seară, tentativa de lovitură de stat eșuase. Hitler a ieșit la radio pentru a transmite oamenilor și a vorbit despre „providența” care l-a salvat. Stauffenberg și mai mulți complici au fost arestați și executați de pluton în acea noapte. Alții au fost descoperiți abia mai târziu. În total, aproximativ 200 de luptători ai rezistenței au fost uciși.

    Istoricul Wolfgang Benz consideră că principalul motiv al eșecului a fost acela că „niciunul dintre liderii militari celebri” din acea vreme, cum ar fi generalul Erwin Rommel, nu a participat. „Cel puțin unul dintre ei trebuia să fie la cârmă, pentru ca apoi oamenii să spună: «Aha, și Rommel vede lucrurile așa, că Hitler este un criminal»”, a spus el.

    Un simbol durabil

    În ciuda eșecului său, rezistența împotriva lui Hitler din 20 iulie 1944 a devenit un simbol puternic. Cu câteva zile înainte, complicele lui Stauffenberg, Henning von Tresckow, ajunsese la concluzia că succesul nu mai conta: important era „că mișcarea de rezistență germană îndrăznise să-și riște viața în fața lumii și în fața istoriei”.

    Au existat și alte operațiuni de rezistență, cum ar fi încercarea eșuată la limită a tâmplarului Georg Elser de a-l ucide pe Hitler folosind o bombă artizanală într-o berărie din München în 1939 sau campania de pliante a unui grup de tineri prieteni cunoscuți sub numele de Trandafirul Alb. Acestea au fost ulterior umbrite pe nedrept de „rezistența târzie, ca să nu spunem întârziată, a elitelor conservatoare”, așa cum a judecat Wolfgang Benz complotul din 20 iulie 1944.

    „Holocaustul nu i-a interesat”

    Amintirea Operațiunii Valkyrie și a tentativei de asasinat s-a schimbat în timp. Multă vreme după încheierea războiului, inițiatorii acesteia erau încă considerați trădători. Soției lui Stauffenberg, de exemplu, i s-a refuzat inițial pensia primită de văduve. Ulterior, conspiratorii au fost desemnați oficial eroi: străzi, școli și cazărmi au fost numite după ei, iar clădirile publice au fost decorate cu steaguri în fiecare 20 iulie. Ceremoniile de depunere a jurământului pentru recruții forțelor armate Bundeswehr au avut loc cu ocazia aniversării: Armata Germaniei democratice i-a invocat pe luptătorii din rezistență care îl înconjurau pe fostul ofițer Wehrmacht, Stauffenberg.

    De ce sunt recrutați soldați bolnavi mintal în Ucraina?

    Potrivit partenerei sale, Olena, Vasyl nu își recunoaște niciodată cu adevărat problemele și este foarte posibil să nu fi făcut-o în timpul examenului fizic pe care l-a primit înainte de a se înrola în armată. Vasyl a fost declarat apt de serviciu și recent trimis în sudul Ucrainei pentru instrucție de bază.

    Olena a încercat să-i explice toate acestea noului comandant al lui Vasyl. După ce a fost mai întâi înțelegător, acesta a respins raportul din 2015 al unei clinici de psihiatrie pe care i l-a adus Olena, spunând că este învechit.

    „Dar cum poate acesta să nu fie motiv de externare, dacă starea lui este incurabilă?”, întreabă Olena.

    DW a văzut raportul, care include o listă a problemelor lui Vasyl. Când este stresat, simptomele se agravează, notează Olena. Asta l-ar transforma într-un pericol nu doar pentru sine, ci și pentru ceilalți.

    O imagine neclară a noului recrut Vasyl, în vârstă de 28 de ani, care primește îngrijiri psihiatrice pentru o tulburare de personalitate din 2015. Imagine: privat

    Cum pot fi recrutați bolnavii mintal?

    Există o bază de date ucraineană la care medicii militari o consultă pentru a afla dacă potențialii recruți sunt bolnavi în vreun fel. Se numește Helsi și pe site-ul său web, în limba engleză, se descrie ca fiind „cel mai popular sistem de informații medicale pentru instituțiile de asistență medicală și portal medical pentru pacienții din Ucraina”.

    Dar diagnosticul psihiatric al lui Vasyl nu se află în acel sistem, spune avocatul ucrainean Yevhen Tsekhmister, deoarece detaliile despre bolile psihologice pot fi salvate acolo doar dacă pacientul își dă permisiunea.

    Vezi toate știrile de pe recrutați soldați bolnavi

    Dacă diagnosticul ar fi existat, atunci, conform Ordinului nr. 402 al Ministerului Apărării, Vasyl ar fi fost inapt pentru serviciu. Ordinul nr. 402 stabilește ce ar trebui să caute examenul medical militar și cum se evaluează aptitudinea unui soldat pentru serviciu.

    Tsekhmister explică faptul că medicii militari au încredere doar în documentele oficiale, deoarece mulți bărbați simulează tulburări psihologice pentru a evita să fie înrolați.

    „Dacă s-ar fi solicitat consiliere juridică mai rapid și s-ar fi furnizat dovezi mai actualizate, Vasyl nu ar fi fost înrolat”, a spus avocatul.
