Green hydrogen by electrolysis
Electricity splits water. The hydrogen is only as clean as the kWh. Offtake, water, and the hours the electrolyser actually runs decide if a project is a plant or a press note.
Green hydrogen explained: production and application
An electrolyser, alkaline or PEM, passes a current through water and yields hydrogen and oxygen. Call it green only when the electricity is renewable and additional, not when a certificate is bought after the fact. Capacity factor is the number that matters: an electrolyser sitting idle for want of cheap power is a stranded asset.
Kerala has hydro, a growing solar pipeline, and industrial offtake in fertiliser, refining, and mobility trials. Water for electrolysis is not free in a dry year. The mechanical package, compressors, storage, safety, sits in the same brief as the electrical incoming.
A site note should name the offtaker, the water source, and the hours. Without those three, hydrogen is a slide.

Policy/2026
Growth for all, and ecology as management
Development and ecology have been set against each other for a long time. Small is not always better, and holding other people back is not sustainability. Growth for everyone, planned so it does not wreck the place, is the job.
Civil/2026
Cost-effective building, specified clearly
Cheap is not the same as cost-effective. The saving is in the method: the wall, the slab and the skill on site, written in the BOQ, not hoped for after the tender.
Hydro/2026
Small hydro, rebuilt as a working station
Older stations still earn if the civil, mechanical, and electrical sides are named. New runners, environmental flows, and protection that keep a plant on the grid.
