Overview

• Power and energy are constraining factors on military

operations

• Likely to continue

• MOD needs improved power and energy management

• Industry is funding relevant development

• MOD has fossil fuel use reduction targets to meet

Enduring challenge areas

• Dismounted soldier applications

• Bases, platforms and the

‘defence enterprise’

Dismounted Soldier

System (DSS) power issues

• Soldiers carry too much

• Batteries contribution significant

• Future capability could increase

power demand – more data = more power

• Need to reduce battery burden

MOD requires a means of transferring

high volumes of time-synced data

while minimising power consumption

What we want

• COTS / MOTS high data rate, low power

consumption, reliable network with no latency

issues

• 1GBaseT (1 Gb/s) Ethernet functionality with

lower power consumption

• OR solution to synchronisation and latency

issues with USB

MOD requires a means of powering

dismounted soldier systems over

multiday missions without excessive

mass

What we want

• Novel, reliable and practical to sustain the

dismounted soldier power needs

• Efficient and practical ways to move power (and

data) around torso and to weapon and helmet

• Better batteries

• Better than state of art energy harvesting

What we don’t want

• Energy harvesting proposals that don’t

– improve state of the art

– compete with batteries over 2-3 day missions

– make reasonable assumptions for resource

• Battery or fuel cell proposals that don’t

– exceed COTS

– or utilise COTS systems in a novel way

Expected bid technical information

• Show an awareness of state of the art and

how the proposal claims to improve on this:

– Novel improved technology

– Novel use of a COTS technology

– Estimated performance

• Evidence or logic for estimates if possible

– Clearly defined deliverables

• Beyond the soldier, defence

activities both foreign and

domestic consume significant

quantities of energy

• Are we resilient?

Bases, platforms and ‘defence

enterprise’

Why fossil fuel?

25 June 2014 OFFICIAL

DSTL/PUB82049

• Well understood properties

• High energy density

• Relatively safe in an operational environment

• Single source of energy reduces logistical burden

Risks

25 June 2014 OFFICIAL

DSTL/PUB82049

• Energy cost increases

• Cost instability

• Future availability of military fuel

grades

• Commercial markets adopting new

types of fuels

Reason for action –

operations

OFFICIAL

• Better resilience has benefits:

– Reduced re-supply missions

• Reduces cost and exposure to

harm

– Increased autonomy of force

elements

– Fight longer, harder, better

– Improve area of influence

Reason for action –

UK infrastructure

OFFICIAL

DSTL/PUB82049

• Better energy resilience of

MOD infrastructure has

benefits:

– Reduced energy cost

– Flexibility to meet demand

– Reduced CO2 emissions linked to

defence

Efficiency

Behaviour

Planning

1. Improve equipment

efficiency through improved

design and technology

insertion

2. Improve operating behaviour

through training

3. Improve planning to consider

the energy demand of

different options
