Heavy industries must decarbonise dramatically to reach net zero. Replacing fossil fuels with green hydrogen, created with renewable energy, is one way to reduce emissions. Examples of green hydrogen being used in various industries are emerging, but as the FT’s Sylvia Pfeifer reports, this carbon-free innovation faces a major challenge to scale up.

Design: ‘The Line’ – A 100% Renewable Energy & Low Carbon Saudi Arabia City
No roads, cars or emissions, it will run on 100% renewable energy and 95% of land will be preserved for nature. People’s health and wellbeing will be prioritized over transportation and infrastructure, unlike traditional cities. Only 200 meters wide, but 170 kilometers long and 500 meters above sea level.
THE LINE will eventually accommodate 9 million people and will be built on a footprint of just 34 square kilometers. This will mean a reduced infrastructure footprint, creating never-before-seen efficiencies in city functions. The ideal climate all-year-round will ensure that residents can enjoy the surrounding nature. Residents will also have access to all facilities within a five-minute walk, in addition to high-speed rail – with an end-to-end transit of 20 minutes.
Astronomy: James Webb Telescope First Images
The first images from the James Webb Space telescope have been revealed. Incredibly clear images of the Carina Nebula, the Eight-Burst Nebula, a galaxy cluster called Stephan’s Quintet and an exoplanet named WASP-96b make up the first set of science data from JWST.
Astronomy: James Webb Telescope In The Cosmos
Decades of work, $10 billion in spending and nearly 14 billion years of cosmic history have brought us to this moment. The first science from the James Webb Space Telescope, the largest and most powerful observatory ever built. What questions will it answer? What new mysteries will discover? What will this new eye on the cosmos reveal? The telescope’s first science images will be out VERY soon. Here’s a quick look at what you can expect when they drop.

Covid-19: Can A Vaccine Be Developed That Lasts?
“Roughly two and a half years into the pandemic, White House officials and health experts have reached a pivotal conclusion about Covid-19 vaccines: The current approach of offering booster shots every few months isn’t sustainable.
Though most vaccines take years to develop, the Covid shots now in use were created in record time—in a matter of months. For health authorities and a public desperate for tools to deal with the pandemic, their speedy arrival provided a huge lift, preventing hospitalizations and deaths while helping people to escape lockdowns and return to work, school and many other aspects of pre-Covid life.”

Science: The Search For Alien Life In The Universe
The thought of finding alien life has fascinated people since the time of the ancient Greeks—but developments in astrobiology could be about to turn this possibility into reality. How do you hunt for life beyond Earth—and might this be the decade when we find it?

Tourism & Climate Change: The Future Of Air Travel
Exotic destinations, or staycations? As we make choices like these, we ask ourselves: Will we ever be able to fly without feeling guilty again? This film examines the tourism business today, and asks how the industry envisages the future.
The pandemic brought the tourist industry to a standstill. But it also highlighted something we have long suspected: Namely, too much travel is bad for the environment.
Not only that, but tourism transforms entire regions – not always for the better. It profoundly impacts communities and often brings benefits for only a very few. But our wanderlust remains. So, do travelers have to decide between the two extremes: exotic destinations (and high carbon footprints) or holidays at home? Given the climate emergency, can we fly without feeling guilty? How environmentally damaging are cruises? And what does it mean to have a sustainable holiday?
This documentary examines an industry that had gotten ahead of itself, even before it was hit by the pandemic. We hear from mayors, tourism managers, a climate expert, an internet activist and a sociologist. The film travels to the European tourist hotspots of Barcelona, Venice and Dubrovnik. The tiny island of Palau in the Pacific Ocean demonstrates how sustainable travel can be sensibly organized, and a Parisian start-up develops a concept for virtual travel experiences.
Opinions: New Frontier For AI, British Stagnation, Story Scene Imagination
