TECHNOTHON 2026
A national innovation challenge aimed at solving the key
technological challenges in Deep-sea mining.
DIVE DEEPER
~6000 m beneath the ocean surface lies a vast reservoir of critical minerals with the potential to power the clean-energy transition.
ENGINEER RESPONSIBLE DEEP-SEA MINING
Advance technologies for environmentally responsible deep-sea mineral extraction through innovation, monitoring and sustainable engineering.

Shape the future of India's deep ocean programme
Technothon 2026 invites Industries, MSMEs, Startups, Incubation centres and Academic researchers to develop innovative engineering solutions for sustainable deep-sea mining and critical mineral exploration.
National platform
Present your work to scientists at NIOT and the Ministry of Earth Sciences.
Real-world problem
Address engineering challenges on India's Deep Ocean Mission.
Awards up to ₹1.2 Cr
A two-stage award structure up to ₹50 lakh per team at Stage II.
Your IP stays yours
IPR remains with participants. NIOT receives only an evaluation licence.
Two problem statements, one deep frontier
Collect polymetallic nodules from 4,500–6,000 m — with or without a vertical riser. Select a statement to explore what you'd be building.
Development of mining system with Innovative Impact less Nodule Collection System with Vertical Riser Transport
The conventional deep-sea mining architecture employs a tracked seabed collector coupled with a vertical riser and lifting system that transports nodules hydraulically or mechanically to a surface support vessel. While technically mature compared to other concepts, significant challenges remain in Collector efficiency, Sediment management, Hydraulic transport efficiency, Energy consumption, Reliability, System weight, Deployment logistics and Environmental footprint.
- Collector vehicle
- Pick-up mechanism
- Hydraulic collection head
- Mechanical collection head
- Nodule separation
- Water management
- Sediment rejection
- Intelligent navigation

Novel ideas beyond the above are encouraged.
Built for industry & research
Technothon 2026 is open to organisations and researchers with the capability to build and deploy deep-sea technology.
How the challenge unfolds
A two-stage journey from registration to milestone-wise fund release — each step a checkpoint on the descent.

Agreement signing
Winning teams formalise the project agreement with NIOT.
Milestone-wise fund release
Project funds are disbursed against agreed development milestones.
Into the deep — six kilometres down
Under India's Deep Ocean Mission, NIOT is engineering the crewed submersible and the seabed machines that will explore the abyssal plains of the Central Indian Ocean — where polymetallic nodules rich in cobalt, nickel and rare earths rest under crushing pressure and perpetual dark.
Technothon 2026 opens that engineering frontier to you. Design the sensors, the sustainable collectors, the navigation and the life-support that make responsible deep-sea exploration possible.
