WSJ Tech News Briefing: Episode Summary
Title: Why Airbus’s Plans for a Green Jet Remain Grounded
Release Date: April 23, 2025
Host: Katie Dayton, The Wall Street Journal
1. Introduction
In this episode of WSJ Tech News Briefing, host Katie Dayton delves into two significant topics shaping the tech and aerospace industries: the evolution of office lighting technologies and Airbus's ambitious yet challenged plan to develop a zero-emissions jet. This comprehensive summary captures the key discussions, insights, and conclusions presented in the episode.
2. Revolutionizing Office Lighting
a. The Problem with Traditional Fluorescent Lighting
Katie Dayton opens the discussion by addressing the ubiquitous issue of harsh, unflattering fluorescent strip lights that commonly plague office environments. She highlights the negative impact these lights have on both aesthetics and employee well-being.
“Anyone who's worked in an office knows about the perils of harsh, unflattering fluorescent strip lights.”

b. Introduction of High-Tech Adaptive Lighting Solutions
The conversation shifts to the innovative programmable lighting solutions being developed to replace traditional fluorescent lights. These new systems are designed to adjust to employees' circadian rhythms and mimic natural outdoor lighting, even in windowless spaces.
“Design firms have developed new programmable lights that can do things like adjust to match employees circadian rhythms and mimic natural outdoor lighting even in a totally windowless space.”
— Katie Dayton [01:21]
c. Enhancing Mental Health and Productivity
Ray Smith, WSJ's careers and workplace reporter, provides a vivid description of these adaptive lighting systems. He emphasizes their dual purpose: improving visual comfort and supporting mental health by aligning lighting conditions with natural biological rhythms.
“It can feel draining or wearying and cold. ... aiming to boost your mental health in some ways, or at least sync with your body clock.”
— Unnamed Reporter [02:13]
The report includes insights from Interseen, a company specializing in such technologies, noting the "Virtual Sun" and "Circadian Sky" products that create the illusion of natural sunlight indoors.
“It's called Virtual sun and Circadian Sky. ... It's these panels that mimic what it looks like outside.”
— Unnamed Reporter [03:10]
d. Economic Incentives for Companies
The discussion also touches on the economic motivations behind investing in advanced lighting solutions. Companies aim to create more appealing office environments to encourage employees to return to the workplace, thereby maximizing the use of their real estate investments.
“The goal is to have them want to spend more time there, even if they're not mandated to be in the office five days a week.”

3. Airbus's Green Jet Ambitions Hit Roadblocks
a. Initial Vision and Commitment
Ben Katz, WSJ's aviation and aerospace reporter, explores Airbus's bold initiative announced in 2020 to develop a hydrogen-powered, zero-emissions jet. This project was intended to position Airbus as a leader in sustainable aviation and provide a competitive edge over rivals like Boeing.
“In 2020, Airbus said it was going to figure out how to build a zero emissions aircraft powered by Hydrogen within 15 years.”
— Ben Katz [05:15]
b. Technological and Industry Challenges
The project has faced significant hurdles, leading to budget cuts and timeline delays. The primary challenges include:
-
Hydrogen Storage: Hydrogen requires cryogenic conditions for storage, necessitating bulky and heavy fuel cells that impact aircraft performance and passenger capacity.
“Hydrogen has to be stored at immensely cold temperatures ... it adds weight and additional equipment onto an aircraft.”
— Ben Katz [07:22] -
Industry Buy-In: The aviation industry's entrenched reliance on jet fuel infrastructure makes the shift to hydrogen complicated and slow.
“Hydrogen isn't the easiest fuel. The aviation industry ... is completely set up for jet fuel.”
— Ben Katz [07:22]
c. Current Status and Future Outlook
After five years and a significant investment of nearly $2 billion, Airbus has delayed the green jet project by up to a decade, now targeting 2045 instead of the original 2035 timeline. The broader ecosystem supporting hydrogen aviation is also behind schedule, contributing to the postponements.
“They were starting to realize that their dreams ... making this 2035 ambition just no longer feasible.”
— Ben Katz [08:46]
Despite these setbacks, Airbus remains committed to the concept, asserting that the substantial investment to date has validated hydrogen's feasibility. However, the company acknowledges the need to redesign the aircraft to achieve commercial viability.
“Airbus is really insisting that the last five years, over $1.5 billion spent ... there is a reasonable route and a feasible route to building the aircraft.”
— Ben Katz [09:29]
d. Broader Industry Implications
Katz contextualizes Airbus's challenges within a broader industry trend where sustainable engineering efforts face delays and reduced investor enthusiasm. Factors such as geopolitical tensions, market pressures, and shifting priorities have contributed to a slowdown in progress towards green technologies.
“It's a combination of two things. ... some of the focus on ESG funding and financing has kind of slipped away.”
— Ben Katz [10:12]
4. Conclusion
The episode underscores the complexities and challenges inherent in transitioning to sustainable technologies, whether in office environments or the aviation industry. While advancements in adaptive lighting promise enhanced employee well-being and productivity, Airbus's stalled green jet project highlights the formidable obstacles in achieving large-scale, zero-emission aviation. These discussions reflect a broader narrative of innovation tempered by practical constraints and shifting economic landscapes.
