Arctic amplification refers to the disproportionately rapid warming of the Arctic compared to the rest of the planet, driven by feedback mechanisms related to ice and snow cover.

Green hydrogen is particularly crucial for decarbonizing sectors that are difficult to electrify or switch to other renewable sources, such as heavy industries (steel, cement) and long-haul transportation.

The mission is expected to create numerous green jobs, stimulate domestic manufacturing of related equipment, and enhance India's export capabilities in the clean energy sector.

The Indian government has shown strong interest and policy support for the Green Hydrogen Mission. The primary challenges are the cost of electrolyzers, renewable energy availability, and infrastructure development.

The National Green Hydrogen Mission was launched by the Indian government in January 2023 with the aim of making India a global hub for green hydrogen production and export.

Green hydrogen is produced through electrolysis, where water is split into hydrogen and oxygen using electricity generated from renewable sources like solar and wind power.

The porous nature of the bio-concrete is specifically engineered to facilitate the settlement and subsequent growth of coral larvae, a critical step in reef restoration.

Healthy coral reefs are crucial for coastal protection against erosion and storm surges, and they support significant economic activities like tourism and fisheries.

Pilot projects for the bio-concrete technology have been successfully implemented in the Great Barrier Reef and the Maldives, demonstrating its effectiveness.

Climate change, particularly ocean warming and acidification, along with pollution and destructive fishing practices, are the primary drivers of coral reef degradation.
