Geoengineering - CO2 Sequestration

Print

Increasing rate of carbon dioxide (CO2) release to atmosphere after industrial revolution had triggered the studies on green house gases effect and its impact on global warming. Sustained worldwide growth in population and economic activity has increased anthropogenic CO2 emissions and are beginning to stress the natural carbon cycle.  Earth’s climate is expected to warm even more rapidly during this century, as global CO2 emissions increase from present rates near 7 GtCy–1, to 15 GtCy–1 or more by 2050. Estimates of warming expected through the 21st century vary among models, but all are responsive to levels of carbon dioxide in the atmosphere. The concentration of CO2 in the atmosphere is increasing at a rate of about 1-2 parts per million (ppm) per year and it is currently around 390 ppm from the pre-industrial level of 280 ppm. Increasing concentration of atmospheric CO2 will exert greenhouse effect that traps solar energy and intern may warm our planet and  changes in regional climates.

Major forums like UN convention of climate change, Kyoto Protocol and Global Climate change program had addressed the mitigation plans in controlling the green house gases to control the human impact in triggering the climate cycle. Our society needs to understand the options available for controlling levels of atmospheric carbon dioxide, and the threat of CO2-induced climate change prove real. If we wait until there is definitive proof of harmful climate change, it will be too late to develop large-scale solutions to the problem. Hence, while addressing the mitigation efforts, carbon dioxide sequestration studies in the ocean is an important field of activity which is in progress in many international laboratories.

a) Objectives

To understand the mechanism of ocean CO2 sequestration techniques in the ocean by capacity building;  study and establish the feasible CO2 capture technology from industrial sources, arriving feasible field executable transportation technology; and  development of ocean instrumentation for EIA observation and monitoring.

b) Participating Institutions:

National Institute of Ocean Technology, Chennai

c) Implementation Plan

To start working on this domain of research to understand the ocean CO2 sequestration techniques for controlling the global warming phenomena by CO2 emission to atmosphere.

Wherever required, it is proposed to work in collaboration with academic institutes, research and development organizations, industries and international organizations. 

d) Deliverables:

CO2 capture, transportation and ocean sequestration technology

e) Budget : 50 crores

(Rs. In crores)
