Dealing with Energy Poverty in India

Issues with the Rural Electrification:

Access: Poor access and consumption with high inequity

Availability

Reliability

Quality

Affordability

Challenges before the Power Sector:

Capacity: Weak infrastructure (electricity, railways etc.)

Not rich in resources: hydrocarbons, land, water, capital

Efficiency: Need to improve; Poor environmental management

Cost: Need to minimize the cost of power generation

IECM-cs Model: Salient Features

Estimation of the performance and costs is directly linked

Multi-pollutant interactions taken into account

Capable of probabilistic analysis

User-friendly graphical interface

Transparent (model inputs and default assumptions)

Provides consistent basis to compare various technology options

Energy Penalty

CCS energy penalty as the increase in energy input per unit of product output due to CCS

EP = (ηref / ηccs ) – 1

As per the IPCC Special Report on CCS, the energy penalty in case of various types of plants: PC = 27% (22-29%)

IGCC = 16% (12-22%)

Oxyfuel = 25% (15-43%)

NGCC = 15% (14-16%)

(IPCC, 2005)

Cost of CCS

Bulk of the cost: Capture (and compression)

Potential revenue: EOR/ ECBM (early adopters)

(IPCC, 2005)

$28-111/tCO2

$1.7-14.8/tCO2

$7-13/tCO2

regarding CCS

Major Concerns or Issues

Technical: Feasibility; Scale-up; Experience

Economic: Expensive; Need for incentives; Viability?

Social: Public acceptance?

Health/Safety: Risk of slow/ accidental leakage

Relevance of CCS

IS IT RELEVANT FOR INDIA?

India and Climate Change

Not a major contributor to the problem (cause); Potential to be part of the solution (mitigation)

Hansen, 2006

India and Climate Change

Not a major contributor to the problem (cause); Potential to be part of the solution (mitigation)

Likely to face disproportionate impacts (extreme events, agriculture, sea-level rise, water availability....)

Vulnerability issues; Need for adaptation and mitigation

Relevance of CCS

Carbon Management Options: Improvements in conversion and generation efficiency

Use of low-C or non-C fuels or energy sources

CO2 Capture and sequestration (CCS)

A Bridging Technology: May allow us to continue the use of conventional fossil fuels without

worrying about the greenhouse effect

CCS as a Carbon Management Option:

How much can we store?

At what cost?

Is the technology ready?

MESSAGE

(IPCC, 2007)

Critical share

Global Cost Curve for GHG Abatement Measures

beyond “Business As Usual”

Ref: Enkvist et al., McKinsey & Company, 2007 (page 38)

Marginal cost of avoiding emissions of 1 ton CO2eq in each abatement demand scenario

Coal: Backbone of India’s Energy Infrastructure

Indian Scenario

In 2014 India’s CO2 emissions totalled 1,931 Mt (BP, 2014);

~ 60% from large (>0.1 Mt) stationary sources.

(Holloway for IEAGHG R&D Programme, 2008)

CCS in India

CCS = Capture + Compression + Transport + Storage + Monitoring?

US/EU: Need to first resolve the issues related to technical feasibility, economic viability, future liability and public acceptance

Need for detailed assessment of CCS potential in India CO2 sequestration in SW India

Conclusion

CCS is a potential mitigation option, but it needs to

overcome several barriers/challenges

The key challenges are: technical feasibility &

scaleup, economic viability and public acceptance

Our priorities as a developing country: Enhancing

capacity; Improving energy efficiency; Reducing

Costs (NOT CCS!!)

RD&D in CCS: Flexibility of future policy options; A

low-cost insurance policy against future

uncertainty (Shackley & Verma, 2008)

Please remember..

We have not inherited this earth

from our ancestors….

We have only borrowed it

from our future generations!
