The lab works on developing methane hydrate and storing CO2 beneath the seabed.
AboutAbout the lab
Sustainable development of seabed resources
The Konno Lab studies the sustainable development of seabed resources and the effective use of the seabed environment.
The lab works on developing methane hydrate, which is expected to become a next-generation natural gas resource.
It is also developing technology to store carbon dioxide by making use of the deep-sea seabed environment.
Research is carried out through collaboration among industry, national research institutes, and universities.
Key terms
- Methane hydrate
- An ice-like substance in which methane is trapped inside cages formed by water molecules
- CCS (carbon dioxide capture and storage)
- Technology that captures CO2 and stores it deep underground so that it is not released into the atmosphere
- Reservoir
- A porous underground geological formation that can hold gas, oil, CO2, and other fluids

ResearchResearch themes
Aiming at the sustainable development of seabed resources and the effective use of the seabed environment, the lab conducts research in collaboration among industry, government, and academia. Its work includes methods for producing gas from methane hydrate, technology for storing CO2 beneath the seabed, and studies of development systems for putting ocean technology to use in society.
*Illustrative imageProducing gas from methane hydrate
The lab is developing methods to produce gas stably and in large quantities from methane hydrate reservoirs beneath the seabed. This is joint research with organizations including the MH21-S R&D Consortium.
*Illustrative imageCCS sealed by hydrate
In collaboration between industry and academia, the lab proposes a new type of CCS in which CO2 stored beneath the seabed forms CO2 hydrate at its boundary with the seafloor and thereby seals itself. Its performance is examined in laboratory experiments using simulated sediments.
*Illustrative imageFrameworks for using ocean technology in society
Using methane hydrate development as an example, the lab examines the roles that society expects of such technology, as well as how to think about development systems and projects. It is building a model that handles production volume and economic evaluation together.
*Illustrative imagePreventing pipeline blockage
Subsea pipelines operate under high pressure and low temperature, so they can become blocked by hydrates. Using a test apparatus that reproduces gas flow, the lab investigates the mechanism by which hydrate particles aggregate.
