Rotterdam's Green Gamble: Can Europe's Largest Port End Its Fossil Era?

Rotterdam's Green Gamble: Can Europe's Largest Port End Its Fossil Era?

Pressure is mounting on the Port of Rotterdam to decarbonize its fossil-fuel–heavy footprint, with a lawsuit demanding a concrete plan to wind down coal, oil and gas flows. The port authority aims to cut its own energy emissions by 90% by 2030, backing a hydrogen hub, onshore power for ships, and low-carbon bunkers while pursuing CCS via the Porthos project. Critics say the port must do more than manage emissions and should accelerate a full transition, arguing the hub’s influence is limited and that global policy and corporate relocation can undermine progress; the ultimate target remains net-zero by mid-century, but the path and pace are hotly debated.

Plug Power Signals Margin Turnaround as Q1 2026 Revenue Climbs 22%

Plug Power reported Q1 2026 revenue of $163.5 million, up 22% year over year, and a 71% improvement in gross margin to negative 13% from negative 55%, driven by higher sales and cost discipline; GAAP EPS was -$0.18, with adjusted EPS -$0.08 after about $140 million of non-cash charges related to convertible debt and warrants. The company remains focused on achieving positive EBITDAS in Q4 2026 as it scales its integrated hydrogen platform, with progress across Material Handling (GenDrive/GenFuel), Electrolyzer Solutions (over 320 MW deployed and more than $8 billion in project pipeline with projects in Portugal, Spain and Canada), and Hydrogen Production (hydrogen fuel sales up 22% and margins up 54 percentage points). Liquidity stood at over $802 million in cash, plus restricted cash, and it expects further asset monetization (~$275 million) and tax-credit proceeds (~$39.2 million) to support its growth and margin expansion.

Five hopeful science breakthroughs reshaping health and energy

Nature highlights five uplifting science stories from 2025–26: infants can now be treated for malaria with the weight-tailored drug artemether-lumefantrine, reducing infant deaths; six Leigh syndrome patients show mobility and breathing improvements after sildenafil (Viagra) treatment, though more trials are needed; engineered bacteria produce hydrogen from waste bread with a catalyst, cutting greenhouse-gas emissions; researchers extract hydrocarbon-rich biofuel from date-palm leaf fibers, offering a new energy source and waste-management benefit; and a US study finds HPV vaccination in boys and men linked to a 46% reduction in several cancers, underscoring the vaccine’s power for cancer prevention.

Ancient underworld waters fuel Earth’s hidden microbial empire

Scientists mapped a global network of hydrogen-rich waters trapped deep in Precambrian shield rocks and identified two reactions— radiolytic breakdown of water and serpentinization—that generate hydrogen, providing a long-lasting energy source for microbes isolated from the surface. Studied across 19 mines in Canada, South Africa, and Scandinavia, the hydrogen output may rival marine systems, suggesting a vast, enduring subsurface biosphere and reshaping ideas about Earth's habitable volume and the search for life on Mars.

Iron and UV light unlock cheap hydrogen from alcohols

Scientists at Kyushu University discovered that mixing methanol with iron ions and sodium hydroxide and then exposing the mixture to UV light triggers a rapid release of hydrogen—921 mmol per hour per gram of catalyst—comparable to costly modern catalysts. The approach works with other alcohols and biomass feeds, offering a cheap, abundant iron-based route to sustainable hydrogen production. Although the reaction mechanism isn’t fully understood yet, the simple setup could be replicated widely and help decouple hydrogen generation from fossil fuels; researchers plan to optimize the process moving forward.

Hidden hydrogen halos reveal thousands more gas reservoirs around galaxies

Astronomers using the Hobby-Eberly Telescope analyzed about half a petabyte of data and found more than 33,000 hydrogen gas halos surrounding galaxies from 10–12 billion years ago (the cosmic noon), up from roughly 3,000 previously detected, suggesting hydrogen is far more widespread than understood and enabling deeper study of early galaxy formation and star formation processes.

Alpine's Alpenglow Hydrogen V6 Roars to 9,000 RPM with Water-Only Exhaust

Alpine’s Alpenglow hydrogen-powered V6 prototype revs to 9,000 rpm, delivering about 740 hp and a top speed of 205 mph while emitting only water vapor. The design uses a pre-chamber and regulator for hydrogen at ~700 bar, with compact storage tanks and standard radiators to maintain aero efficiency. Blue energy-recovery brake lights and a transparent acrylic rear spoiler underscore that this car is a mobile lab for testing hydrogen in high-performance applications, suggesting clean-energy ICE viability without heavy battery packs.

Cosmic dawn mapped in 3D reveals a sea of light across the early universe

Astronomers used line-intensity mapping from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) to create a 3D map of the early universe, revealing a vast ‘sea of light’ from hydrogen Lyman-alpha emission that traces galaxy and gas distributions 9–11 billion years ago. The work helps probe gravity and dark energy’s role in cosmic evolution, leveraging hundreds of millions of spectra; further noise-reduction advances will enable mapping even fainter structures and tighten cosmological constraints.

Earth’s Core Could Hold 45 Oceans of Water, New Study Suggests

A Nature Communications study led by Motohiko Murakami suggests hydrogen from early Earth became chemically bound inside the metallic core as iron hydrides, not as free gas or water. If hydrogen accounts for up to about 0.36% of the core’s mass, this could translate to roughly 45 oceans’ worth of water, implying Earth’s surface water may be just a fraction of a much larger deep-water inventory formed during planet formation.

NASA readies second full fueling test for SLS in Artemis countdown drills

NASA will conduct a second, full wet dress rehearsal (WDR-2) of the Space Launch System at Launch Complex 39B, loading more than 700,000 gallons of liquid hydrogen and liquid oxygen and counting down to a simulated T-0 around Feb. 19 after a Feb. 12 confidence test that yielded useful data but pointed to a ground equipment issue; a firm launch date will follow a successful WDR-2, with March 6 cited as the earliest possible window.

Earth's Core May Harbor Massive Hydrogen Reserves, Redrawing Water's Origin

Earth's Core May Harbor Massive Hydrogen Reserves, Redrawing Water's Origin

A Nature Communications study estimates Earth’s molten iron core could host a vast hydrogen reservoir—potentially the planet’s largest—amounting to about 0.07% to 0.36% of the core’s weight, equivalent to roughly nine to 45 hydrogen oceans. Using atom probe tomography and high-pressure iron experiments to mimic core formation, researchers examined how hydrogen interacts with silicon and oxygen under extreme conditions. If confirmed, this suggests Earth acquired most of its water during its early growth rather than via late comet deliveries and may relate to heat flow that helps power the magnetic field; however, the estimate relies on indirect methods with uncertainties, and further work is needed to refine the numbers.

New Study Reveals Hydrogen's Limited Climate Benefits and Global Budget Challenges

A study published in Nature warns that hydrogen, often seen as a clean energy source, may contribute to climate change by prolonging methane's presence in the atmosphere, thus slightly increasing global temperatures. The rise in hydrogen emissions, mainly from human activities like industrial leaks and fossil fuel use, indirectly enhances warming by reducing atmospheric detergents that break down methane, highlighting the need for a deeper understanding of hydrogen's role in climate dynamics.
