Many carbon-intensive businesses need to make

key decisions today to address the challenges,

and opportunities, that they will face tomorrow.

“Meeting the world’s growing energy

needs in an environmentally responsible

manner is a tremendous challenge.

Technology is essential to answering

that challenge.”

Jeroen van der Veer, Chief Executive, Royal Dutch Shell plc


The CEM programme integrates technology

and expertise from across Shell to help the

organisation reduce its own and its clients’

carbon footprints.

The flexible and modular programme assesses

a client’s energy use and carbon dioxide

production and compares its current position

with the most desirable operating practices.

Strategies for mitigation are then proposed,

which may include energy-efficiency or carbon

optimisation programmes, and the trading of

emissions allowances.

Developing a road map

The first step in a CEM programme often

involves making an assessment of your energy

and carbon position with a view to saving

energy, reducing costs and lowering carbon

dioxide emissions. Working closely with your

key staff, we will first analyse your position

and capabilities, and then review the response

options. A gap analysis is performed, and the

financial value of closing this gap is quantified.

Creating a carbon and energy inventory

Steps can be taken to validate your opportunities

for carbon optimisation and energy-efficiency

improvements in more depth. Baselining,

benchmarking and equipment and systems

performance gap analysis methodologies are

important techniques here. The cost and ease of

their implementation are also recorded.

These assessments may include the following:

• country-wide or enterprise-wide – portfolio

analysis; fuel switching options; funding

or offsetting within the Clean Development

Mechanism (CDM) or with Joint

Implementation (JI) projects; and change

readiness indicators;

• site-wide – benchmarking; site energy and

loss assessments; utilities modelling; project

analysis; and risk analysis; and

• equipment performance – equipment

gap analysis and benchmarking (for fired

equipment, heat exchangers and turbines,

for example); data mining; and process

simulation for heat or energy flows.

The carbon and energy management offer framework

Evaluating strategic choices

Investment options undergo a full cost–benefit

analysis that takes account of the required

operational or capital expenditure, the impact

on carbon dioxide emissions, and energy

cost savings or carbon allowance prices. This

is a complex analysis, but a cost-of-carbonabatement

study can help by prioritising

possible energy saving and emissions

mitigation measures in terms of the amount

of carbon dioxide saved and the cost of the

project work needed to achieve the saving

(Figure 1).

Strategic choices to be made could include

carbon dioxide abatement through make-or-buy

decisions for power; fuel switching evaluations;

and heat/power technologies such as

cogeneration.

Delivering on the strategy

Depending on the findings of the analyses

carried out previously, we may recommend

activity across three key areas: energy

efficiency, carbon optimisation and

emissions trading.

Energy efficiency solutions may include best

available technology assessments, hydrocarbon

management reviews, integrated equipment

performance evaluations, catalyst optimisation,

as well as our proven energy-efficiency

programme. Energy cost savings are typically

achieved through the intelligent application of

technology and by modifying behaviours and

processes. Programmes can be structured around

minimal capital expenditure for rapid payback.

Shell’s technology solutions

Shell has been active in deploying

technology across three key areas in order

to reduce emissions:

a) improve energy efficiency – examples

include energy optimisation and

operational-excellence programmes;

Carbon optimisation solutions may stem

from an earlier cost-of-carbon abatement

study. A masterplan could be considered that

provides a structured approach to delivering

carbon mitigation implementation proposals

in the context of your business’ operating

environment. Implementation activities may

include optimising catalysts, sequestration

or biofuels opportunities, carbon dioxide

mineralisation, and carbon dioxide sales.

Through our links with Shell Trading, one of

Europe’s leading emissions trading desks, we

can also offer value-adding services around

the Kyoto Protocol’s flexible mechanisms.

For instance, we can help you to trade

allowances. We can also support you as you

b) generate energy cleanly – introduce

renewable energy sources or switch to

less carbon-intensive fuels; and

c) mitigate emissions – prevent the release of

carbon dioxide into the environment by

capturing it for sale to industrial users or for

underground storage.

seek to identify qualifying opportunities for JI

and CDM projects, and to register them.

Ongoing support

To help capture value effectively and

provide sustainable results, we can also

offer implementation assistance and ongoing

support. For instance, we can assist with

detailed change-management programmes,

build in operator training programmes and

facilitate knowledge transfer.

We also offer a sophisticated energy

management system. This is a combination

of structured management processes and

monitoring tools – linked to real-time data

– that aims to operate a plant and its energyusing

systems at their most energy-efficient

operating points. Human intervention is an

integral part of the energy management

system and so the data is made available to

operations and production staff for them to

monitor and, where necessary, take action.
