Abstract India heavily relies on coal for about 70 % of its energy demand, leading to a concerning 29 increase in CO 2 emissions from 2015 2022. The need alternate fuels is evident with rising demand and the rapid depletion fossil fuels. Green hydrogen emerges as solution, leveraging renewable sources mitigate environmental impact. This study assesses five high-speed wind locations green production, analysing resource potential using six different turbine (WT) models. A comprehensive techno-economic analysis was conducted evaluate feasibility considering factors like annual production (AEP), levelized cost (LCOE), (LCOH). Furthermore, quantified carbon mitigated instead conventional methods. Additionally, assessed storage capacity. Results indicated Mandvi (S2) most location, boasting capacity factor 50.51 AEP by WT4 13.273 GWh, yielding 221.21 tons annually. Cost reveals an LCOE 0.0225 $/kWh LCOH 2.3103 $/kg. utilizing at S2 location could 12.37 Mt/year emissions.

Abstract Accurate forecasting of heat demand in district heating networks is essential for their efficient and sustainable operation. This paper presents a novel approach using random parameter linear regression model to forecast demand, distinguishing itself from classical models by its ability address unobserved heterogeneity among parameters. Through case study Estonia utilizing data 2018 2023 considering seasonality consumption patterns, the investigates determinants networks. Two were trained non-heating seasons. Results indicate significant impacts weather conditions, energy prices, time day, network infrastructure on supply during season, while only day electricity prices drivers with no notable influence conditions. Prediction accuracy was slightly enhanced model, mean absolute percentage error 9.66 % compared 9.99 Multi Linear Regression Model testing set.
