- 1Canadian telescope maps earliest hydrogen glow of universe▼Canadian telescope directly maps earliest glow of hydrogen, opening a new window on the universe
A Canadian telescope has for the first time directly mapped the earliest glow of hydrogen in the universe, according to an announcement from researchers at the University of British Columbia. The result, reported through EurekAlert! and UBC science communications, opens what researchers describe as a new observational window on the early cosmos, allowing astronomers to study the epoch when the first hydrogen gas filled the universe.

Plug Power's stock climbed after the company announced a deal to supply electrolyzers to Arcadia eFuels, which is developing a synthetic fuel plant in Denmark. The agreement strengthens Plug Power's foothold in Europe's emerging green hydrogen market, and investors reacted positively to the commercial validation of its electrolyzer technology.

Green steel production faces a geography problem: low-emission steel is made where renewable energy is cheap, while buyers are often elsewhere. A book-and-claim system, similar to mechanisms used for green hydrogen and renewable power certificates, would let companies purchase the environmental attributes of clean steel produced in one region to support decarbonisation goals even if their physical supply comes from another.
- 4Big Bang nucleosynthesis enters era of precision cosmology●The earliest of the Big Bang's four cornerstones is nucleosynthesis: the primeval creation of the light elements. It now
Big Bang nucleosynthesis, the primeval formation of the universe's light elements such as hydrogen and helium, is now being studied with precision-cosmology methods, according to a science commentary drawing on Ethan Siegel's Big Think column. As measurement of the cosmic microwave background and element abundances sharpens, the earliest of the Big Bang's four cornerstones can be tested against observations with unprecedented accuracy.
- 5Chinese reactor claims fusion breakthrough using boron fuel●When it comes to cleantech, boron is not boring. https://www. scmp.com/news/china/science/ar ticle/3369086/chinese-comme
A Chinese commercial reactor is reported to have achieved nuclear fusion producing clean hydrogen, with boron used as the fuel. The development is drawing attention in cleantech and renewable energy circles because hydrogen from fusion could offer a low-carbon energy route, and China's progress in commercialising the technology is being closely watched.
- 6FuelCell Energy stock rises Tuesday, outperforming the market●FuelCell Energy Inc. stock rises Tuesday, outperforms market
FuelCell Energy Inc. shares closed higher on Tuesday, beating the broader market's performance. The gain drew attention from investors tracking clean-energy stocks, though the company did not announce specific news alongside the rise. Trading activity in fuel-cell and hydrogen-related names continues to draw interest amid ongoing focus on alternative energy investments.
- 7Bloom Energy Jumps 11% as Fuel Cell Selloff Reverses●Bloom Energy Rallies 11% as Fuel Cell Selloff Reverses; FuelCell Surges 7%, Plug Power Rises 3%
Fuel cell stocks rebounded sharply after a recent selloff. Bloom Energy led the recovery with an 11% rally, while FuelCell Energy surged 7% and Plug Power rose 3%. The bounce suggests investors stepped back in to buy the dip across the hydrogen and fuel cell sector, though no company-specific news was cited for the move.
- 8Metal-organic frameworks could reshape liquid hydrogen storage●Rethinking liquid hydrogen storage with metal-organic frameworks
Researchers are proposing metal-organic frameworks as a way to rethink how liquid hydrogen is stored. The materials, with their highly porous structures, could offer denser and more efficient hydrogen containment than conventional cryogenic tanks. The work is drawing attention amid growing interest in hydrogen as a clean fuel for transport and industry, where storage remains a key technical hurdle.
