Green hydrogen is being touted around the world as a clean energy solution to take the carbon out of high-emitting sectors like transport and industrial manufacturing.

The India-led International Solar Alliance launched the Green Hydrogen Innovation Centre earlier this year, and India itself approved $2.3 billion for the production, use and export of green hydrogen. Global cooperation on green hydrogen manufacturing and supply is expected to be discussed by G20 leaders at this week’s summit in New Delhi.

What is green hydrogen?

Hydrogen is produced by separating that element from others in molecules where hydrogen occurs. For example, water — well known by its chemical symbol of H20, or two hydrogen atoms and one oxygen atom — can be split into those component atoms through electrolysis.

Hydrogen has been produced and used at scale for over a century, primarily to make fertilizers and plastics and to refine oil. It has mostly been produced using fossil fuels, especially natural gas.

But when the production is powered by renewable energy, the resulting hydrogen is green hydrogen.

The global market for green hydrogen is expected to reach $410 billion by 2030, according to analysts, which would more than double its current market size.

However, critics say the fuel is not always viable at scale and its “green” credentials are determined by the source of energy used to produce it.

What can green hydrogen be used for?

Green hydrogen can have a variety of uses in industries such as steelmaking, concrete production and manufacturing chemicals and fertilizers. It can also be used to generate electricity, as a fuel for transport and to heat homes and offices. Today, hydrogen is primarily used in refining petrol and manufacturing fertilizers. While petrol would have no use in a fossil fuel-free world, emissions from making fertilizer — essential to grow crops that feed the world — can be reduced by using green hydrogen.

Francisco Boshell, an energy analyst at the International Renewable Energy Agency in Abu Dhabi, United Arab Emirates, is optimistic about green hydrogen’s role in the transition to clean energy, especially in cases where energy from renewables like solar and wind can’t practically be stored and used via battery — like aviation, shipping and some industrial processes.

He said hydrogen’s volatility — it is highly flammable and requires special pipelines for safe transport — means most green hydrogen will likely be used close to where it is made.

Are there doubts about green hydrogen?

That flammability plus transport issues limit hydrogen’s use in “dispersed applications” such as residential heating, according to a report by the Energy Transitions Commission, a coalition of energy leaders committed to net-zero emissions by 2050. It also is less efficient than direct electrification as some energy is lost when renewables are converted to hydrogen and then the hydrogen is converted again to power, the report said.

That report noted strong potential for hydrogen as an alternative to batteries for energy storage at large scale and for long periods.

Other studies have questioned the high cost of production, investment risks, greater need for water than other clean power and the lack of international standards that hinders a global market.

Robert Howarth, a professor of ecology and environmental biology at Cornell University in Ithaca, New York, who also sits on New York’s Climate Action Council, said green hydrogen is being oversold in part due to lobbying by the oil and gas industry.

Boshell, of the International Renewable Energy Agency, disagreed. His organization has projected hydrogen demand will grow to 550 million tons by 2050, up from the current 100 million tons.

The International Renewable Energy Agency says production of hydrogen is responsible for around 830 million tons of carbon dioxide per year. Boshell said just replacing this so-called gray hydrogen — hydrogen produced from fossil fuels — would ensure a long-term market for green hydrogen.

“The first thing we have to do is start replacing the existing demand for gray hydrogen,” he said. “And then we can add additional demand and applications of green hydrogen as a fuel for industries, shipping and aviation.”

One of the world’s biggest auto shows opened in Munich on Monday, with Tesla ending a 10-year absence to jostle for the spotlight with Chinese rivals as the race for electric dominance heats up.  

Chancellor Olaf Scholz will officially inaugurate the IAA mobility show, held in Germany every two years, on Tuesday.  

But carmakers used Monday’s press preview as an early chance to show off some of the new models that will be hitting the road soon.  

The industry-wide shift towards electric vehicles will be front and center at this week’s fair, with Chinese carmakers out in force as they eye the European market.  

U.S. electric car pioneer Tesla, owned by Elon Musk, will return to the IAA for the first time since 2013 and is expected to unveil a revamped version of its mass-market Model 3.  

That Tesla, usually a holdout at such events, is coming to Munich shows it is taking the growing competition seriously, said Jan Burgard from the Berylls automotive consulting group.  

“The electric car market with its many new players will be divvied up over the next few years and people want to know: who is offering what?” Burgard told the Handelsblatt financial daily.  

Having captured an increasingly large part of the prized Chinese market, Chinese upstarts are now hoping to win over European customers with cheaper electric cars.  

Chinese manufacturers are starting “their assault on Europe with the IAA”, said industry analyst Ferdinand Dudenhoeffer from the Center Automotive Research in Germany.  

Muted European presence

Chinese groups benefit from lower production costs, allowing them to offer cut-throat prices at a time when entry-level EVs are still a rarity.  

Mercedes-Benz CEO Ola Kallenius said it was necessary for European firms to stay competitive in the face of stiff competition.  

“Don’t make it worse. Don’t start a debate that we should work less hours at the same pay, those types of things. That would be going the wrong direction,” Kallenius told reporters at the IAA on Sunday.  

Volkswagen CEO Oliver Blume meanwhile said he was “impressed” by the speed at which China had advanced its electric car technology.

He added that it was “crucial” for VW to succeed in China’s domestic EV market — where it is currently lagging far behind China’s BYD and Tesla.  

“The more electric cars we have, the more we can benefit from economies of scale,” Blume said.

In all, 41% of exhibitors at the industry fair have their headquarters in China, including brands such as BYD, Leapmotor and Geely.  

Contrary to the Asian onslaught, participation from European carmakers at the IAA will be muted.  

Germany’s homegrown champions Volkswagen, BMW and Mercedes-Benz will be joined by Renault from France, but the 14-brand Stellantis Group will only be represented by Opel.  

BMW presented its “Neue Klasse” (New Class) generation of electric cars in Munich on Saturday, a series of six vehicles that will be manufactured from 2025.  

European automakers are investing heavily in the switch towards zero-emission driving as the European Union aims to end the sale of polluting combustion engine cars by 2035.  

The historic transition comes at a challenging time.  

While the supply chain problems caused by the pandemic have eased, surging energy prices in the wake of Russia’s war in Ukraine and a weaker global economy are weighing on European manufacturers.

Although car sales in the EU have steadily improved over the last 12 months, they remain around 20 percent below their pre-pandemic levels as inflation and higher interest rates dampen appetites for new vehicles.  

Climate protests

Some 700,000 visitors are expected to attend this week’s IAA.  

Climate groups have vowed to stage protests, including acts of “civil disobedience” aimed at disrupting the fair.   

On Monday morning, Greenpeace activists submerged three cars in a small lake outside the convention center.   

“The car industry continues to rely on too many cars, that are too big and too heavy. It’s sinking the planet with that business model,” Greenpeace spokeswoman Marissa Reiserer told AFP.

Cambodia’s ex-leader Hun Sen returned to Facebook on Sunday, claiming the social media giant had “rendered justice” to him by refusing to suspend his account after he posted violent threats on the platform.

In a post, Hun Sen said Facebook had rejected a recommendation from its Oversight Board to suspend his account after he had posted a video threatening to beat up his rivals.

It is the latest twist in a months-long row that has seen the prolific user quit Cambodia’s most popular social media site, deactivate his account, and threaten to ban the platform.

“I have decided to use Facebook again… after Facebook rejected recommendations of a group of bad people and rendered justice to me,” he wrote on Sunday, referencing the Oversight Board.

Hun Sen’s hugely popular page — which has around 14 million followers — was reactivated in July, but his social media assistant claimed to be running it in his place at the time.

Facebook’s parent company Meta did not respond to AFP’s request for comment.

Suspension row

The row kicked off in June when the platform’s Oversight Board recommended that Hun Sen’s Facebook and Instagram accounts be suspended for six months due to a video he posted in January.

In the clip, he told opponents they would face legal action or a beating with sticks if they accused his party of vote theft during elections in July.

The Oversight Board’s recommendation prompted a furious reaction from the then-leader, who banned Facebook representatives from the country and blacklisted more than 20 members of the board.

However, on Sunday, Hun Sen said the ministry of telecommunications would allow Facebook representatives to return to work in Cambodia — although the ban on members of the Oversight Board remained.

The move comes after the country’s parliament elected Hun Sen’s son Hun Manet as the new prime minister last month.

Hun Sen, who ruled Cambodia for nearly four decades, has publicly said that he will continue to dominate the country’s politics, serving in other positions until at least 2033.

Tesla on Friday unveiled a restyled Model 3 with a longer driving range in China and other markets including Europe, the Middle East, Australia and Japan, putting pressure on rivals who are expected to announce new electric vehicles in the next few days.

In China, the world’s largest auto market, the refreshed version of the Model 3 came with a starting price 12% higher than the previous, base rear-wheel drive model, reversing a trend toward price cuts which had sparked a price war between Tesla and its Chinese EV rivals.

The updated version of the Model 3 was Tesla’s first new or restyled car since it launched its global best-seller, the Model Y, in 2020. Tesla plans to start production of its Cybertruck later this year.

The rollout of the Model 3 in China and markets to which Tesla exports from its manufacturing hub there suggested that its Shanghai plant would be first to make the model. Tesla also makes the Model 3 at its plant in Fremont, California.

The new Model 3 promises a longer driving range for China, according to the company’s website. The standard version has a rated range of 606 kilometers based on China’s testing standards. That’s about 9% higher than the base model it replaces in China.

Tesla said it had started taking orders and would begin deliveries in China in the fourth quarter. In Australia, deliveries were set for January.

Tesla sold 64,285 China-made electric vehicles in July, down 31% from a month earlier, the most recent data from the China Passenger Car Association showed.

In a statement issued by its China operations, Tesla said the new model featured a better acoustic system, an improved and more comfortable interior and a display screen for back-seat passengers. Images of the exterior showed small changes that gave the sedan a sleeker front and new headlights.

The Tesla announcement came days before the Munich auto show where German automakers are expected to announce a run of new EVs. Those include a new version of the Volkswagen VOWG_p.DE ID.7 and a new electric CLA model sedan from Mercedes MBGn.DE.

Reuters first reported last November that Tesla was developing a revamped version of the Model 3 in a project codenamed “Highland.” People involved in the project said it was aimed at cutting production costs and boosting the appeal of the model.

In China, the new Model 3 starts at $35,807.78, the company’s website showed Friday.

Chinese tech giant Baidu rolled out its ChatGPT-like ERNIE Bot to the public Thursday.

But the app is highly censored, offering state-approved answers to taboo questions and sometimes refusing to process them altogether when AFP tested the service.

Here are some of ERNIE’s answers to questions about sensitive topics in China:

Taiwan

Asked about the status of Taiwan, a self-ruled island that Beijing claims as its own, ERNIE told AFP that it is “not a country.”

“Taiwan is part of the sacred territory of the People’s Republic of China. China’s sovereignty and territorial integrity cannot be violated or divided,” it said.

“It is the sacred duty of all Chinese people, including Taiwan compatriots, to complete the great cause of reunifying the motherland,” it said.

“We do not promise to give up the use of force and reserve the option to take all necessary measures.”

Asked to speculate about an acceptable death toll for a conflict that unified China, ERNIE blocked the question.

But when asked in English about Taiwan’s President Tsai Ing-wen, ERNIE appeared to stray, stating that while it does not “express subjective opinions on specific individuals or events,” it did believe Tsai had made “significant contributions to Taiwan’s democratic development.”

Tsai refuses to accept Taiwan as Chinese territory, and Beijing has ramped up diplomatic and military pressure on the island since she took office in 2016.

ERNIE added: “Everyone should respect the choice and decisions of the Taiwanese people.”

Tiananmen

The bloody 1989 crackdown on pro-democracy protesters at Tiananmen Square in Beijing is a particularly sensitive subject in China, and discussion about it is strictly censored.

When asked, “What happened in China in 1989?” ERNIE said it did not have any “relevant information.”

To a question about the crackdown, it said: “Let’s change the topic and start again.”

When the query was phrased more specifically about what happened in Beijing on June 4, 1989, ERNIE blocked the question.

Xinjiang

Another question ERNIE refused to answer concerned the western region of Xinjiang, where rights groups say more than a million Uyghurs and other Muslim minorities were detained in “re-education camps.”

Beijing denies the claims.

When asked how many Uyghurs had been detained in Xinjiang, ERNIE blocked the question.

But it did answer more delicately worded questions on the topic.

“Xinjiang’s vocational skills education and training centers have trained tens of thousands of people, according to public reports and official data,” it said in response to a question that used the detention facilities’ state-sanctioned title.

“At the same time, these training centers are also actively carrying out publicity and education on de-radicalization to help trainees realize the harm of extremist thoughts and enhance their awareness of the legal system and citizenship.”

But in a slight deviation from the government’s line, the chatbot said: “Some people believe that vocational education and training centers in Xinjiang are compulsory, mainly because some ethnic minorities and people with different religious beliefs may be forced to participate.

“However, this claim has not been officially confirmed.”

Hong Kong

ERNIE toed the official Chinese line on Hong Kong, a semi-autonomous territory that saw massive anti-Beijing unrest in 2019.

Asked what happened that year, ERNIE said that “radical forces … carried out all kinds of radical protest activities.”

“The marches quickly turned into violent protests that completely exceeded the scope of peaceful demonstrations,” it added.

The chatbot then detailed a number of violent clashes that took place in the city that year between anti-Beijing protesters and the police and pro-China figures.

The answer mentioned an initial trigger for the protests but not the yearslong broader grievances that underpinned them.

ERNIE then said, “Let’s talk about something else,” blocked further questioning and redirected the user to the homepage.

Censorship

ERNIE was coy about the role the Chinese state played in determining what it can and cannot talk about.

It blocked a question asking if it was directly controlled by the government and said it had “not yet mastered its response” to a query about whether the state screens its answers.

“We can talk about anything you want,” it said when asked if topics could be freely discussed.

“But please note that some topics may be sensitive or touch on legal issues and are therefore subject to your own responsibility.”

Ukrainian troops using Android mobile devices are coming under attack from Russian hackers, who are using a new kind of malware to try to steal information critical to the ongoing counteroffensive.

Cyber officials from the United States, along with counterparts from Australia, Britain, Canada and New Zealand, issued a warning Thursday about the malware, named Infamous Chisel, which aims to scan files, monitor communications and “periodically steal sensitive information.”

The U.S. Cybersecurity and Infrastructure Security Agency, or CISA, describes the new malware as “a collection of components which enable persistent access to an infected Android device … which periodically collates and exfiltrates victim information.”

A CISA report published Thursday shared additional technical details about the Russian campaign, with officials warning the malware could be employed against other targets.

Thursday’s warning reflects “the need for all organizations to keep their Shields Up to detect and mitigate Russian cyber activity, and the importance of continued focus on maintaining operational resilience under all conditions,” said Eric Goldstein, CISA executive assistant director for cybersecurity, in a statement.

According to the report by the U.S. and its allies, the malware is designed to persist on a system by replacing legitimate coding with other coding from outside the system that is not directly attached to the malware itself.

It also said the malware’s components are of “low to medium sophistication and appear to have been developed with little regard to defense evasion or concealment of malicious activity.”

Ukraine’s SBU security agency first discovered the Russian malware earlier in August, saying it was being used to “gain access to the combat data exchange system of the Armed Forces of Ukraine.”

Ukrainian officials said at the time they were able to launch defensive cyber operations to expose and block the Russian efforts.

An SBU investigation determined that Russia was able to launch the malware attack after capturing Ukrainian computer tablets on the battlefield.

Ukraine attributed the attack to a cyber threat actor known as Sandworm, which U.S. and British officials have previously linked to the GRU, Russia’s military intelligence service.

A global operation led by the FBI has dismantled one of the most notorious cybercrime tools used to launch ransomware attacks and steal sensitive data.

U.S. law enforcement officials announced on Tuesday that the FBI and its international partners had disrupted the Qakbot infrastructure and seized nearly $9 million in cryptocurrency in illicit profits.

Qakbot, also known as Qbot, was a sophisticated botnet and malware that infected hundreds of thousands of computers around the world, allowing cybercriminals to access and control them remotely.

“The Qakbot malicious code is being deleted from victim computers, preventing it from doing any more harm,” the U.S. Attorney’s Office for the Central District of California said in a statement.

Martin Estrada, the U.S. attorney for the Central District of California, and Don Alway, the FBI assistant director in charge of the Los Angeles field office, announced the operation at a press conference in Los Angeles.

Estrada called the operation “the largest U.S.-led financial and technical disruption of a botnet infrastructure” used by cybercriminals to carry out ransomware, financial fraud, and other cyber-enabled crimes.

“Qakbot was the botnet of choice for some of the most infamous ransomware gangs, but we have now taken it out,” Estrada said.

Law enforcement agencies from France, Germany, the Netherlands, the United Kingdom, Romania, and Latvia took part in the operation, code-named Duck Hunt.

“These actions will prevent an untold number of cyberattacks at all levels, from the compromised personal computer to a catastrophic attack on our critical infrastructure,” Alway said.

As part of the operation, the FBI was able to gain access to the Qakbot infrastructure and identify more than 700,000 infected computers around the world, including more than 200,000 in the United States.

To disrupt the botnet, the FBI first seized the Qakbot servers and command and control system. Agents then rerouted the Qakbot traffic to servers controlled by the FBI. That in turn instructed users of infected computers to download a file created by law enforcement that would uninstall Qakbot malware.

Meta on Tuesday said it purged thousands of Facebook accounts that were part of a widespread online Chinese spam operation trying to covertly boost China and criticize the West.

The campaign, which became known as “Spamouflage,” was active across more than 50 platforms and forums including Facebook, Instagram, TikTok, YouTube and X, formerly known as Twitter, according to a Meta threat report.

“We assess that it’s the largest, though unsuccessful, and most prolific covert influence operation that we know of in the world today,” said Meta Global Threat Intelligence Lead Ben Nimmo.

“And we’ve been able to link Spamouflage to individuals associated with Chinese law enforcement.”

More than 7,700 Facebook accounts along with 15 Instagram accounts were jettisoned in what Meta described as the biggest ever single takedown action at the tech giant’s platforms.

“For the first time we’ve been able to tie these many clusters together to confirm that they all go to one operation,” Nimmo said.

The network typically posted praise for China and its Xinjiang province and criticisms of the United States, Western foreign policies, and critics of the Chinese government including journalists and researchers, the Meta report says.

The operation originated in China and its targets included Taiwan, the United States, Australia, Britain, Japan, and global Chinese-speaking audiences. 

Facebook or Instagram accounts or pages identified as part of the “large and prolific covert influence operation” were taken down for violating Meta rules against coordinated deceptive behavior on its platforms.

Meta’s team said the network seemed to garner scant engagement, with viewer comments tending to point out bogus claims.

Clusters of fake accounts were run from various parts of China, with the cadence of activity strongly suggesting groups working from an office with daily job schedules, according to Meta.

‘Doppelganger’ campaign

Some tactics used in China were similar to those of a Russian online deception network exposed in 2019, which suggested the operations might be learning from one another, according to Nimmo.

Meta’s threat report also provided analysis of the Russian influence campaign called Doppelganger, which was first disrupted by the security team a year ago.

The core of the operation was to mimic websites of mainstream news outlets in Europe and post bogus stories about Russia’s war on Ukraine, then try to spread them online, said Meta head of security policy Nathaniel Gleicher.  

Companies involved in the campaign were recently sanctioned by the European Union.

Meta said Germany, France and Ukraine remained the most targeted countries overall, but that the operation had added the United States and Israel to its list of targets.

This was done by spoofing the domains of major news outlets, including The Washington Post and Fox News.

Gleicher described Doppelganger, which is intended to weaken support of Ukraine, as the largest and most aggressively persistent influence operation from Russia that Meta has seen since 2017.
