The Liverpool City Region is abandoning its hydrogen bus initiative, deciding to convert its fleet of 20 vehicles to battery electric power due to a critical shortage of hydrogen fuel. This move follows a troubled rollout where half the buses never carried a single passenger and the other half saw extremely limited service. While the […]

A new study suggests that offshore wind farms can significantly benefit marine ecosystems, acting as artificial reefs that foster biodiversity. Researchers discovered that the concrete foundations of wind turbines support a thriving community of stationary organisms, which in turn creates a complex food web. The areas surrounding these installations were found to host a greater […]

A new project supported by the European Space Agency has yielded a groundbreaking solar tracker that functions without electricity, motors, or any human control. Drawing inspiration from sunflowers, researchers at the Université de Bretagne Sud have engineered a system using advanced 4D-printed materials. These smart composites autonomously change shape when exposed to varying light and […]

Recent analyses of hydrogen-powered public transit projects reveal a significant discrepancy between their “zero-emission” branding and their actual climate impact. When the entire fuel lifecycle is accounted for—from production and transport to leakage—hydrogen buses and ferries often generate CO2 emissions comparable to, or even exceeding, their diesel counterparts. This counterintuitive result stems from energy-intensive supply […]

A novel iron-air battery technology has achieved a major milestone by successfully connecting to a public power grid for the first time in the Netherlands. Developed by the Dutch startup Ore Energy, the system went online at Delft University of Technology, demonstrating a low-cost, long-duration energy storage solution. By utilizing a reversible rusting process with […]

For the first time on record, global electricity generation from wind and solar power has surpassed that of coal. A report from the climate think tank Ember reveals that during the first six months of 2025, the growth in these renewable sources was substantial enough to meet the world’s rising electricity demand, marking a significant […]

A new urban model developed by researchers at Concordia University in Montreal demonstrates how neighbourhoods can achieve near-complete vegetable self-sufficiency and cut carbon emissions by 98%. The framework, detailed in the journal *Sustainability*, combines the 15-minute city concept with localized food production and renewable energy. By repurposing small portions of existing urban spaces for agriculture […]

A significant milestone for the UK’s domestic battery industry has been achieved with the creation of the first cylindrical sodium-ion cell made entirely from local materials. Developed through a partnership between energy storage firm Batri and Swansea University, the 18650-format cell incorporates innovative components, including a composite carbon anode derived from Welsh coal. This breakthrough, […]

A new economic analysis suggests that the growth of rooftop solar increases electricity costs for households without it, while the adoption of electric vehicles (EVs) tends to lower bills for everyone. The working paper from University of Maryland economists quantifies a cost shift where utilities, facing reduced revenue from solar-equipped homes, raise overall rates. This […]

In Lund, Sweden, a new parking garage is demonstrating a groundbreaking approach to sustainable construction by using decommissioned wind turbine blades as its facade. The Niels Bohr parking garage, designed by architect Jonas Lloyd, tackles the significant environmental challenge of recycling old rotor blades, which are typically sent to landfills. In a partnership with energy […]
