In September 2022, EnerVenue signed a master supply agreement covering 250 MWh from 2023 to 2025, with deliveries of 50, 100, and 100 MWh, for an earlier generation of its product. The order it now calls its first commercial contract at multi-megawatt-hour scale is 26 containerized units totaling 11 MWh for an unnamed Chinese oil and gas producer, with the first three due in December from a production line that made its first conforming cell at the end of September. Eleven megawatt-hours across 26 units works out to about 423 kWh per container. Launch coverage of the Energy Prism by…

India’s utility-scale storage market faces a critical execution test as the Solar Energy Corporation of India Limited issues a Request for Selection targeting 800 MW / 3,200 MWh of standalone battery storage capacity. Published under tender reference SECI/C&P/IPP/15/0010/26-27, the SECI-ESS-IV solicitation establishes a tariff-based competitive bidding mechanism for four-hour duration assets operating on a Build-Own-Operate framework. As the Intermediary Procurer, SECI will execute 20-year Power Purchase Agreements (PPAs) with winning developers while backing these commitments through Power Sale Agreements (PSAs) with buying entities. The technology-agnostic tender allows grid interconnections at either the Inter-State Transmission System (ISTS) or State Transmission Utility…

When energy infrastructure operators evaluate blending hydrogen into natural gas transmission networks, the safety calculus appears straightforward at first glance. However, quantitative risk assessments reveal a surprising physical reality: overall pipeline risk does not scale linearly with hydrogen concentration. In a high-pressure 10-kilometer transmission pipeline operating at 84 bar and 50 °C, the maximum individual risk does not occur with pure natural gas or pure hydrogen. Lower Mass Flow Rates Do Not Equal Lower Risk When a pipeline breach occurs, fluid density determines release dynamics. Substituting natural gas with lighter hydrogen molecules lowers mixture density, reducing mass discharge rates through…

India’s green hydrogen industry is entering a more commercially significant phase as developers begin converting government-backed production ambitions into binding international offtake agreements. Publicly announced commitments involving ACME Group, AM Green and Larsen & Toubro’s L&T Energy GreenTech now point to an export pipeline of roughly 1.2 million tonnes per year of green and renewable ammonia, alongside about 100,000 tonnes per year of green methanol. The significance is not simply the volume. The agreements increasingly connect Indian production projects with Japanese and European buyers through long-term contracts, take-or-pay structures and government-supported mechanisms designed to address the central weakness of the…

Europe’s €10 million effort to train battery industry workers is facing scrutiny over whether its reported success reflects genuine skills development or inflated participation figures. The European Battery Alliance Academy, implemented by EIT InnoEnergy, announced more than 100,000 learners in December 2024. However, questions remain over how those numbers were calculated and whether the programme delivered the workforce capabilities Europe needs. The central issue is measurement. The reported total was based on certificates issued rather than necessarily on unique individuals. Participants completing multiple courses could therefore be counted repeatedly. Significant discrepancies have also emerged between reported participation figures for individual…
