Scaffolding and green pipes envelop a refinery in the port of Rotterdam where Finnish giant Neste is preparing to significantly boost production of sustainable aviation fuel.

Switching to non-fossil aviation fuels that produce less net greenhouse gas emissions is key to plans to decarbonise air transport, a significant contributor to global warming.

Neste, the largest global producer of SAF, uses cooking oil and animal fat at this Dutch refinery.

Sustainable aviation fuels are being made from different sources such as municipal waste, leftovers from the agricultural and forestry industry, crops and plants, and even hydrogen.

These technologies are still developing and the end product is more expensive.

But these fuels will help airlines reduce CO2 emissions by up to 80 percent, according to the International Air Transport Association.

Global output of SAF was 250,000 tonnes last year, less than 0.1 percent of the more than 300 million tonnes of aviation fuel used during that period.

“It’s a drop in the ocean but a significant drop,” said Matti Lehmus, CEO of Neste.

“We’ll be growing drastically our production from 100,000 tonnes to 1.5 million tonnes next year,” he added.

There clearly is demand.

The European Union plans to impose the use of a minimum amount of sustainable aviation fuel by airlines, rising from two percent in 2025 to six percent in 2030 and at least 63 percent in 2050.

Neste has another site for SAF in Singapore which will start production in April.

“With the production facilities of Neste in Rotterdam and Singapore, we can meet the mandate for EU in 2025,” said Jonathan Wood, the company’s vice president for renewable aviation.

Vincent Etchebehere, director for sustainable development at Air France, said that “between now and 2030, there will be more demand than supply of SAF”.

– ‘Need to mature technologies’ –

Air France-KLM has reached a deal with Neste for the supply of one million tonnes of sustainable aviation fuel between 2023 and 2030.

It has also lined up 10 year-agreements with US firm DG Fuels for 600,000 tonnes and with TotalEnergies for 800,000 tonnes.

At the Rotterdam site, two giant storage tanks of 15,000 cubic metres are yet to be painted.

They lie near a quay where the fuel will be transported by boat to feed Amsterdam’s Schiphol airport and airports in Paris.

The Franco-Dutch group has already taken steps to cut its carbon footprint, using 15 percent of the global SAF output last year — or 0.6 percent of its fuel needs.

Neste’s Lehmus said there was a great need to “mature the technologies” to make sustainable aviation fuel from diverse sources such as algae, nitrocellulose and synthetic fuels.

Air France CEO Anne Rigail said the prices of sustainable aviation fuel were as important as their production.

Sustainable fuel costs 3,500 euros ($3,800) a tonne globally but only $2,000 in the United States thanks to government subsidies. In France, it costs 5,000 euros a tonne.

“We need backing and we really think the EU can do more,” said Rigail.

Olympic chief Bach says AI can be a game changer for athletes

IOC president Thomas Bach delivers his keynote speech at the Olympic AI Agenda launch
Share this:

IOC president Thomas Bach said artificial intelligence can help identify talented athletes “in every corner of the world” as he unveiled the Olympic AI Agenda in London on Friday.

Bach, speaking at Olympic Park, which hosted the 2012 Games, said the Olympic movement needs to lead change as the global AI revolution gathers pace.

“Today we are making another step to ensure the uniqueness of the Olympic Games and the relevance of sport, and to do this, we have to be leaders of change, and not the object of change,” said the International Olympic Committee president.

The former fencing gold medallist said it was vital to have a “holistic” approach to create an “overall strategy for AI and sport”.

Bach, speaking less than 100 days before the start of the Paris Olympics, said “unlike other sectors of society, we in sport are not confronted with the existential question of whether AI will replace human beings”.

“In sport, the performances will always have to be delivered by the athletes,” he said. “The 100 metres will always have to be run by an athlete -– a human being. Therefore, we can concentrate on the potential of AI to support the athletes.

“AI can help to identify athletes and talent in every corner of the world. AI can provide more athletes with access to personalised training methods, superior sports equipment and more individualised programmes to stay fit and healthy.”

Bach said other advantages of AI included fairer judging, better safeguarding and improved spectator experience.

The Olympic AI Agenda comes from the IOC AI working group -– a high-level panel of global experts including AI pioneers and athletes, set up last year.

When asked about the potential negatives of AI, Bach was keen to emphasise the importance of free choice in sport.

“He and she, or the parents, must still have the free choice,” said the German. “So a guy who is then maybe identified as a great athlete in wrestling must still have the chance to play tennis and cannot be sorted out from these sports.”

– Vonn ‘jealous’ –

Former Olympic skiing champion Lindsey Vonn, who also spoke at the London event, told AFP she envied current athletes, who could use AI to enhance their training.

“I’m very jealous that I didn’t have any of this technology when I was racing because I just really feel that it’s going to enhance the athlete’s experience all around,” she said.

“Athletes can utilise AI in training to enhance their knowledge from training like, for example, skiing on the mountain but then also off the mountain in the gym recovery times,” added the American.

“The more we understand about your body, about the sport, about performance, the better you can adjust as an athlete.

Vonn, 39, also said AI would be a vital tool for talent identification, particularly in nations without the resources to scout talent.

“You can give them access to AI through a cell phone and you do a series of tests and they can identify ‘OK this athlete would be a great, a 40-metre dash sprinter, or this athlete would potentially be an amazing high jumper,” she said. 

“You have the ability then to find the talent and give them resources through things they already have like a cell phone.”

Meta releases beefed-up AI models

Meta founder and CEO Mark Zuckerberg contends freshly released Meta AI is the most intelligent digital assistant people can freely use
Share this:

Meta on Thursday introduced an improved AI assistant built on new versions of its open-source Llama large language model.

Meta AI is smarter and faster due to advances in the publicly available Llama 3, the tech titan said in a blog post.

“The bottom line is we believe Meta AI is now the most intelligent AI assistant that you can freely use,” Meta co-founder and chief executive Mark Zuckerberg said in a video on Instagram.

Being open source means that developers outside of Meta are free to customize Llama 3 as they wish and the company may then incorporate those improvements and insights in an updated version.

“We’re excited about the potential that generative AI technology can have for people who use Meta products and for the broader ecosystem,” Meta said.

“We also want to make sure we’re developing and releasing this technology in a way that anticipates and works to reduce risk.”

That effort includes incorporating protections in the way Meta designs and releases Llama models and being cautious when it adds generative AI features to Facebook, Instagram, WhatsApp, and Messenger, according to Meta.

“We’re also making Meta AI much easier to use across our apps. We built it into the search box right at the top of WhatsApp, Facebook, and Instagram messenger, so any time you have a question, you can just ask it right there,” said Zuckerberg in the video.

AI models, Meta’s included, have been known to occasionally go off the rails, giving inaccurate or bizarre responses in episodes referred to as “hallucinations.”

Examples shared on social media included Meta AI claiming to have a child in the New York City school system during an online forum conversation.

– Slow and steady –

Meta AI has been consistently updated and improved since its initial release last year, according to the company.

“Meta’s slower approach to building its AI has put the company behind in terms of consumer awareness and usage, but it still has time to catch up,” said Sonata Insights chief analyst Debra Aho Williamson.

“Its social media apps represent a massive user base that it can use to test AI experiences.”

By weaving AI into its family of apps, Meta will quickly get features powered by the technology to billions of people and benefit from seeing what users do with it.

Meta cited the example of refining the way its AI answers prompts regarding political or social issues to summarize relevant points about the topic instead of offering a single point of view.

Llama 3 has been tuned to better discern whether prompts are innocuous or out-of-bounds, according to Meta.

“Large language models tend to overgeneralize, and we don’t intend for it to refuse to answer prompts like ‘How do I kill a computer program?’ even though we don’t want it to respond to prompts like ‘How do I kill my neighbor?’,” Meta explained.

Meta said it lets users know when they are interacting with AI on its platform and puts visible markers on photorealistic images that were in fact generated by AI.

Beginning in May, Meta will start labeling video, audio, and images “Made with AI” when it detects or is told content is generated by the technology.

Llama 3, for now, is based in English but in the coming months Meta will release more capable models able to converse in multiple languages, the company said.

US Congress to take on TikTok ban bill — again

TikTok est depuis plusieurs mois dans le collimateur des autorités américaines, de nombreux responsables estimant que la plateforme de vidéos courtes et divertissantes permet à Pékin d'espionner et de manipuler ses 170 millions d'utilisateurs aux Etats-Unis
Share this:

The US House of Representatives will again vote Saturday on a bill that would force TikTok to divest from Chinese parent company ByteDance or face a nationwide ban.

The measure has been written into a massive $61 billion aid bill for Ukraine, Israel and Taiwan, which could ease its passage in both chambers of the US Congress.

Under the bill, ByteDance would have to sell the app within a few months or be excluded from Apple and Google’s app stores in the United States.

It would also give the US president the authority to designate other applications as a threat to national security if they are controlled by a country deemed hostile.

TikTok slammed the bill, saying it would hurt the US economy and undermine free speech. 

“It is unfortunate that the House of Representatives is using the cover of important foreign and humanitarian assistance to once again jam through a ban bill,” a company spokesman said.

He added a ban would “trample the free speech rights of 170 million Americans, devastate 7 million businesses, and shutter a platform that contributes $24 billion to the US economy annually.”

Western officials have voiced alarm over the popularity of TikTok with young people, alleging that it is subservient to Beijing and a conduit to spread propaganda, claims denied by the company and Beijing.

Joe Biden reiterated his concerns about TikTok during a phone call with his Chinese counterpart Xi Jinping in early April.

The House of Representatives last month approved a similar bill cracking down on TikTok, but the measure got held up in the Senate.
