Increasing efficiency of application technology is
creating an large and unmet demand foroff-grid powerat
small-scale
•LED Lighting •Intelligent load management
•Small-scale computing power •Electronic Displays
— 20 fold efficiency
improvement in
near-term
— Galaxy S4 as
powerful as 2009
high end laptop @
fraction of power*
— New technologies
easier to control (eg
LED lighting and
displays)
— Efficient LED TVs
— Arrival of low power
OLEDs
— Passive e-displays
•Wireless technology •Solid State Drives (SSDs)
— Rapid growth in
wireless capability
— Increasing device
connectivity
— lower quiescent
power
— Reduced size

Technical limitations of current distributed power
generation is stifling growth in applications.
• Technology •Requirement for 50W continuous load?
• ICE generators
— Highly inefficient (<1%) at
lower powers
— High service costs
— Noisy and polluting
• Batteries
— Lead-acid : lower cost but
too heavy
— Lithium Ion: lighter but
very high capital cost
• Solar PV
— large area required
— not practical in northern
winters
— do not work in shade
— Lead acid : 1 visit per week / 24 hour charge
time / 250kg battery pack / ~£1500 pack cost
— Lithium ion : 1 visit per week / 12 hour charge
time / 125kg battery pack / ~£10,000 pack cost
— ~750 liters of diesel per month
— frequent service visits
— noise, air and ground pollution
— 20 m2
of PV array only gives 90% availability
— Requires very large energy store battery
— Even if footprint available, shading can further
reduce efficiency
NO PRACTICAL SOLUTION BETWEEN 5W and 250W CONTINUOUS

ICE gensets are extremely inefficient at low
output powers
• Very mature, low cost technology but with
some fundamental limitations
– Inefficient, particularly at lower powers
– Small petrol genset will be less than 5% efficient at
100W and about 2% efficient at 50W
– Noisy & polluting
– Smaller units have very short service life
• Hymera efficiency ranges from 30% to 50%

Fuel cells
• An electro-chemical device that converts
a ‘replenishable fuel’ into electrical power
without the presence of high temperature
combustion
• A battery where the electrodes and
reactants are separated and can be
recharged by adding more reactant rather
than ‘recharging’
• advantages..
– Efficient – especially with H2
– Silent
– Reliable (long service life and long
service interval)
– Scaleable (mW to MWatts)

Linde developed HYMERA II and launched in
UKin September2014
Key improvements /developments
— Variable output voltage (single unit serves
multiple markets)
— Remotely configurable/operable (essential
requirement of stand-alone off-grid market)
— Rugged metal case
— Extended lifetime guarantee
— Extended operating temperature rang
— DC only (110Vac / 230Vac versions not
required)
— Single side air inlet / outlet (simplifying OEM
integration)
— Significantly lower operating costs compared
to Hymera 1 (50%)

Data and Communications
Power for rapid deployable security cameras
— A number of customers deploy high
spec security system with night time
vision, lights and loudspeaker to
replace security guard.
— used to use conventional diesel
generators to power very high spec
50W security camera
— Main cost is diesel generator (> £1000
per month) but still much lower cost
than conventional security guard (fast
growing market)
— Benefits of using HYMERA and
Hydrogen are:
—Clean and silent operation
—Longer Runtimes/Less interaction
—Lower cost than diesel

12. Welfare cabins and temporary offices
— Possible to use modern technology to
bring base electrical load to well below
100W, even for sizeable welfare cabin
— Move heating load to ‘Webasto’
type heaters
— LEDlights & PIRs
— Efficient waterheaters
— Power large welfare cabin with 2-3 x K
cylinders per week + diesel (in winter)
— Massive potential reductions in diesel fuel
consumption can compensate for mixed
fuel (H2 + diesel)

13. — offers very significant cost savings, in fuel
and servicing, over conventional diesel
generators
— PV alone not viable due to low sun levels
in December & January (50W load would
require 15m2 of PV to get through winter)
— Conventional cylinders viable in some
locations
— Applications: Cameras, temporary
accommodation, remote monitoring and
control, lighting, etc
