However, sectors such as long-haul aviation, shipping, backup power, and some industry applications depend on high-density, storable fuels. Many strategies emphasize hydrogen as a solution; however, significant concerns remain regarding the scale-up of clean hydrogen production, as well as associated infrastructure requirements and handling costs. Large-scale pipeline networks and storage facilities require large investments and strong coordination across sectors, leaving such strategies vulnerable to political instability and the risk of stranded assets.</div><div>We analyze the cost-effectiveness of methanol as a hedge against these challenges. Methanol is liquid at ambient conditions, compatible with existing infrastructure, and is already a major industrial feedstock, with increasing use as a shipping fuel. In a European energy system model, methanol emerges as a cost-effective platform chemical to fuel shipping, aviation, and high-value chemical production to meet stringent emissions targets. The absence of hydrogen and methane networks increases system costs by only 2%–6%, with methanol also emerging as a cost-effective fuel for backup power. Renewable Fischer-Tropsch liquid fuels from CO<sub>2</sub> and sustainable biomass can play a complementary role. Together, renewable liquids utilizing biomass residue streams can reduce dependence on large, politically fragile infrastructure projects and provide a transitional bridge between today’s fossil fuel regime and a future net-zero energy system dominated by electrification and renewable fuels.</div><div><div>Electrification of sectors such as land transport and building heating is a cost-effective pathway to deep decarbonization. However, some sectors still require energy-dense fuels—including aviation, shipping, and backup power—or chemical feedstocks. Although a “hydrogen economy” is often proposed to fill these hard-to-electrify gaps, it faces challenges in transport, storage, and infrastructure coordination. We introduce a “minimal methanol backstop” to supply residual demand in highly electrified systems. As a liquid fuel, methanol is easy to store and transport and avoids infrastructure lock-in. Produced from hydrogen and carbon monoxide, it can help integrate biogenic carbon from decentralized biomass wastes and residues.

It could replace fossil-based hydrogen and help reduce carbon emissions in industry and energy systems. However, today’s electrolysis process is still expensive and energy intensive, mainly because it must also produce oxygen through a slow reaction that requires costly materials and yields little value. In this work, we address this limitation by replacing oxygen production with zinc oxidation—a reaction that is faster and uses abundant, low-cost zinc—while simultaneously generating hydrogen gas and valuable zinc oxide nanoparticles. This approach reduces the required energy and turns what is normally a wasted byproduct into a useful material that can help offset production costs. Such systems could be directly paired with renewable energy sources, making hydrogen production more practical and cost-effective in real-world applications. More broadly, this study shows that rethinking electrolysis to produce valuable materials instead of low-value oxygen can open new pathways toward more efficient, affordable, and scalable green hydrogen production.</div><div><div>Water electrolysis is a promising electrochemical route for producing green hydrogen, which is essential for achieving carbon neutrality. However, conventional systems are limited by high energy demands, primarily due to the sluggish oxygen evolution reaction (OER) that produces low-value oxygen as a byproduct. In this study, we introduce an oxygen-free water electrolysis system that replaces the OER with electrochemical synthesis of ZnO nanoparticles through zinc oxidation. The process operates via two coupled half-reactions: 2H<sub>2</sub>O + 2e<sup>−</sup> → H<sub>2</sub> + 2OH<sup>−</sup> and Zn → Zn<sup>2+</sup> + 2e<sup>−</sup>, yielding an overall cell potential of E<sup>0</sup> = −0.07 V. At 500 mA cm<sup>−</sup><sup>2</sup>, the system achieves stable operation with energy consumption of only 32.16 kWh kgH<sub>2</sub><sup>−1</sup>, markedly outperforming previous decoupled and alternative oxidation reactions-assisted water electrolysis systems.

However, in state-of-the-art monolithic all-perovskite tandems, the indispensable interconnecting layers heavily rely on acidic and hygroscopic poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and interdiffusing gold (Au) layers, which largely impede stability, especially under elevated temperatures. In this work, we report a robust interconnecting layer design for all-perovskite tandems by employing a bithiophene-triphenylamine small molecule modified with an amphiphilic conjugated polyelectrolyte to replace PEDOT:PSS as the hole transport layer (HTL) in tin-lead (Sn-Pb) perovskite subcells, enabling superior hole extraction and, importantly, enhanced interface robustness. Furthermore, we substitute the conventional (sub)nanometer-thick Au recombination junction in the interconnecting layer with a highly transparent sputter-coated indium-doped zinc oxide (IZO) layer, which effectively eliminates metal diffusion-induced reactions and minimizes parasitic optical absorption.&lt;/div&gt;&lt;div&gt;The improved interconnecting layer enables a certified PCE of 30.19% for double-junction tandems, along with enhanced operational stability even under the combined stressors of elevated temperature and simulated sunlight. In a preliminary compatibility assessment using a triple-junction device structure, we achieved PCEs of up to 27.1%. Considering the demonstrated universality in neat lead-based cells as well, we thus expect further adoption of our newly designed interconnecting layers in multi-junction thin-film photovoltaics with more than two junctions and across different tandem technologies, aiming for high efficiencies while ensuring long-term stability.&lt;/div&gt;&lt;div&gt;&lt;div&gt;Robust interconnecting layers are critical for all-perovskite tandems but are typically limited by acidic poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and interdiffusive gold, compromising stability.

Existing imaging methods capture morphological changes but not lithium concentration dynamics inside cathode particles, leaving ion transport to be interpreted through classical diffusion models. Here, we directly visualize lithium chemical-state evolution in operating ASSBs using an X-ray-transparent, pressure-compatible pouch cell with operando X-ray absorption microscopy. Despite dynamic changes in state of charge, domain-specific lithium heterogeneity stays pinned and reappears upon current reversal, a behavior that concentration gradients cannot explain but that a stress-coupled free-energy landscape can, by stabilizing non-uniform lithium configurations near quasi-equilibrium. This stress-imprinted topology correlates with progressive degradation, evolving from early dislocations to rock-salt phases during cycling. Enhancing lithium mobility suppresses stress accumulation, restores homogeneous (de)lithiation, and markedly improves long-term stability.
