Researchers at Monash University have demonstrated a multiscale reduced graphene oxide architecture achieving 99.5 Wh/L volumetric energy density in ionic liquid electrolytes, positioning carbon-based supercapacitors within striking distance of lead-acid battery performance while maintaining power delivery advantages. The development addresses a persistent limitation in electrostatic storage devices, where conventional carbon-based supercapacitors typically deliver below 10 Wh/L, substantially lower than the 30-50 Wh/L range of lead-acid systems.​ Material Processing Enables Surface Area Utilization The performance gains stem from a rapid thermal annealing process applied to natural graphite oxide precursors, creating curved graphene structures with controlled ion pathways. This approach unlocks previously…

Three workers were hospitalized following a hydrogen tank explosion at the Cahpsa industrial park near Asunción on November 30, with one in serious condition and two suffering severe burns. The incident, which prompted a complete facility shutdown and triggered renewed local complaints about hydrogen operations in residential zones, underscores a pattern of recurring safety failures across the global hydrogen sector, even as the industry scales toward clean energy targets. Pattern of critical failures during non-routine operations The Cahpsa explosion follows a fatal October blast at SK Energy’s Ulsan refinery in South Korea, where two contract workers died after mistakenly opening…

With the European Commission’s second Union list of Projects of Common Interest and Projects of Mutual Interest, hydrogen infrastructure has grown from a niche category to a core element of energy planning. More than 130 transmission projects and over 500 hydrogen-related proposals now populate European maps. Still, only a select fraction carries the coveted PCI/PMI status, raising questions about how such designations are granted and whether they target true system-critical investments or speculative bets on future market growth. From first to second list: scaling up and narrowing down The first PCI list under the revised TEN‑E Regulation included 65 hydrogen…

Global final energy consumption has grown 1.8% annually over the past two decades while GDP expanded 3.4% yearly, establishing a decoupling trend that electrification could dramatically accelerate. Analysis from the Energy Transitions Commission projects that electrification will reduce final energy demand by 24% over the next 25 years, even as global economic output doubles, challenging conventional assumptions that prosperity growth necessitates proportional energy consumption increases. This efficiency dividend stems from fundamental thermodynamic advantages electric systems hold over combustion-based alternatives, creating cost and carbon reduction pathways that align rather than conflict. The efficiency differential between electric and fossil fuel applications reveals…

The thirtieth UN climate conference in Belém, Brazil, concluded with developed nations committing to triple climate adaptation finance for vulnerable countries by 2035, while systematically avoiding binding language on fossil fuel reduction that over 80 nations demanded. This outcome crystallizes a pattern emerging across recent COP gatherings: financial mechanisms advance incrementally while decarbonization timelines remain deliberately ambiguous, creating a structural disconnect between stated temperature targets and enforceable transition pathways. The final agreement text omits explicit references to coal, oil, or natural gas phasedown commitments, despite coalition pressure from Colombia, Germany, Kenya, and similar economies seeking concrete transition obligations. Energy exporter…

Fluence Energy’s evaluation of India as a battery energy storage system manufacturing hub confronts a market paradox: ambitious capacity projections totaling 411 GWh by FY 2031-32 meet current installed capacity of just 4 GWh as of December 2024, creating a 103-fold expansion requirement within seven years. The gap between forecast demand and operational infrastructure exposes whether India’s BESS trajectory represents genuine grid modernization momentum or premature scaling of production capabilities ahead of confirmed offtake. The US-based BESS provider, controlled by AES Corporation and Siemens, commands approximately 25% global market share through existing manufacturing in the United States and Vietnam. India’s…

The distinction between hydrogen concentration and hydrogen accumulation in subsurface systems represents the central engineering challenge facing natural hydrogen commercialization, a gap that current exploration enthusiasm has largely overlooked. While geological surveys map prospective zones and media coverage amplifies discovery potential, reservoir drive mechanisms and recovery efficiencies will ultimately determine which projects achieve industrial scale production versus remaining geological curiosities. TO LEARN MORE FROM EXPERTS, REGISTER FOR OUR MASTERCLASS Natural hydrogen’s formation mechanisms—serpentinization of iron-rich ultramafic rocks at 200-300°C, radiolysis from gamma-emitting granites, methane pyrolysis at extreme temperatures, and speculative mantle degassing—produce subsurface concentrations through multiple pathways. Yet concentration presence…

French infrastructure developer HDF Energy has committed to a $500 million investment pipeline across Vietnam’s energy and transport sectors, with Ho Chi Minh City positioned as the primary deployment zone for hydrogen-powered mobility and port infrastructure projects. The announcement, delivered Thursday by HDF Energy’s Vietnam country director Tran Khanh Viet Dung to HCMC Vice Chairman Bui Xuan Cuong, marks the most substantial foreign commitment to Vietnam’s nascent hydrogen economy. The investment strategy targets four distinct verticals: a hydrogen-powered river bus network on the Saigon River, green port development at Can Gio, renewable energy systems for the Con Dao Special Administrative…

How an Austrian media executive ignored the “experts,” bought a car online in 2014, and accidentally became an electric mobility prophet In 2014, Franz Liebmann did something that made his colleagues think he’d lost his mind. He spent €100,000 on a car he’d never test-driven, from a company everyone said would be bankrupt within months, using technology the automotive press dismissed as “a toy for showoffs.” Eleven years and 800,000 kilometers later, that car is still running. And Franz? He’s still driving it, with no plans to ever buy another car again. WATCH THE FULL INTERVIEW The Moment Everything Changed…

The production cost gap has widened to over 30% between Chinese and European manufacturers, fundamentally reshaping who will control the global automotive industry. The Anatomy of a Cost Crisis Manufacturing a small SUV in China costs approximately USD 7,000 less than producing the same vehicle in Germany or the United States. This gap isn’t primarily about labor rates or energy prices: those factors contribute less than 20% to the difference. The battery alone explains nearly 40% of the manufacturing cost disparity for electric vehicles, with Chinese battery cell prices running 30% lower than in Europe and 20% lower than in…
