hydrogen

Episode 1604 discusses hydrogen and its historical use in balloons, connecting science to technology. The episode references hydrogen's role in 1783.

Hydrogen was considered a solution for decarbonizing heavy vehicles like long-haul trucks, but battery-electric trucks are now leading the competition against hydrogen-powered alternatives.

Hyundai is investing $6 billion in a new steel plant in Louisiana, which aims to use hydrogen for low-carbon production but has stated it will use natural gas when operational in 2029. The project was announced by President Trump, Louisiana Governor Jeff Landry, and Hyundai executives, highlighting both economic and environmental implications.

China's provincial governments have released their 15th five-year plans (2026-2030), aligning with national climate goals like peaking carbon emissions by 2030. Plans emphasize solar, wind, hydrogen, and new-energy vehicles (NEVs), with regional variations in focus, such as Zhejiang's 90GW solar target and Jilin's 50% NEV sales goal by 2030.

Europe is accelerating its focus on hydrogen and biofuels as strategic solutions to reduce fossil fuel dependence amid rising energy security concerns. Industry and policymakers highlight infrastructure and cost barriers as key challenges to scaling these green technologies.

The article argues that Europe's pursuit of hydrogen energy security involves appropriating land, water, and renewable electricity from its southern neighbors. It compares this approach to colonialism, suggesting a pattern of resource exploitation.

Researchers have developed a new porous glass material that can trap CO2 and hydrogen by combining ancient glassmaking techniques with modern chemistry. By adding sodium and lithium compounds, the team made the material more processable and shapeable. This breakthrough has potential applications in clean energy, gas storage, and advanced manufacturing.

Storing carbon dioxide in rocks while producing hydrogen from them could provide a climate benefit, with potential for geothermal power generation. Multiple groups are working to develop this approach.

Scientists suggest that deep within Uranus and Neptune, extreme pressures and temperatures may create a 'superionic' hybrid phase of carbon and hydrogen, where hydrogen atoms move fluidly through a rigid carbon structure. This discovery could explain the planets' unusual magnetic fields and reshape understanding of heat and electricity flow in their interiors.
