The Business of FirstLight Energy LimitedFirstLight Energy Limited focuses on the utilisation of renewable and sustainable energy technologies, to
provide clients in the public and private sector, with solutions that are designed to reduce both energy cost and consumption and to support the client in the achievement of their environmental
responsibilities.
FLE design, install and maintain systems encompassing the following technologies:-
Solar ThermalThermal Energy StoresUrban Wind TurbinesVoltage Regulators
Air De-stratification SystemsHybrid Lighting
FLE is also committed to a number of R&D projects to advance technologies to provide leading edge solutions to clients needs, whilst at the same time developing a strong IP base.
These include:-
Advanced heat stores using phase change materialsLight transmission - hybrid technology for the bio fuels industry
Wind turbines design to counter wind turbulence
The company is currently negotiating a distribution deal for inter - seasonal heat storage technology and an advanced air to air heat pump.
Topics for Discussion
1.Phase Change Material
2.Hybrid Lighting Technology
3.Algae Growth
Phase Change Materials
SunStream Energy Stores
UtilizingPhase
ChangeMaterials
By creatingan effective method of
utilising the phase change of materials it is possible to store
largerquantities of energy
thanusing water.
Typically up to 4 times for
equivalent volume of water
when used in conjunction
with the insulated jacket
Why SunStream Energy Stores
Benefits 1Acting as a storage buffer
Reducing the number of times a boiler starts and stops we can improve its
efficiency.
Running the boiler longer helps reduce carbon deposits as the flue temperature
reaches its peak efficiency.
Up to 25% energy reduction
Boiler on/off cycles no power tanks
Typically 30- 40,000 cycles /season
Boiler on/off cycles with power tanks
Typically 4 - 5000 cycles per season
Impact on boilers
Benefit 2Impact on Solar Thermal
Greater energy storage will enable better usage of available thermal energy and provides for the option
of increasing the size of the solar array to provide more free energy and to compensate
for the lower winter sun
We can achieve an increase in energy storage of 25%
70-80 ºC Commercial Heating systems
62ºC Boiler system / solar
45ºC Heat Pumps
And now low temperature PCM for cooling systems.
Temperature Range of PCMcan be variable
SunStream Energy StoresBenefits / Features
Efficient storage system for solar energy
Substantially improves most boiler efficiencies
Combines systems can reduce energy consumption by up to 70%
100 year life span 10 year guarantee
No maintenance or corrosive materials
Can be stored both vertically or horizontally
TUV certified
Can be used in both domestic and commercial situation
SunStream Energy Stores
The future:-
We are working with :
•Ciba Chemicals•Nottingham University•South East England Development Agency•PERA
In the development of new types of PCM thermal storage.
The Future is here now
In January 2009 we will be launching a new concept in PCM storage allowing us :
•Faster heat transfer rates•Lower installation costs
•Modular units•Direct replacement of hot water cylinder
•Low temperature PCM for cooling systems
All at a lower price!!
Hybrid Lighting
To capture sunlight and distribute it, using optical fibres, into the interior of a
building to provide premium quality, controllable lighting capable of reducing energy
consumption.
Hybrid LightingSystem Objective
Hybrid Lighting
The Solar Collector
The solar collector consists of a two-axis tracking mechanism that supports a 1.2 metre diameter plastic primary mirror, a smaller secondary mirror, and a fibre optic receiver unit.
The collector tracks the sun using a microprocessor-based controller that accurately calculates the position of the sun given the local GPS co-ordinates and the local time.
BenefitsBrings natural sun light into buildings
Improves productivityReduces downtime
Reduces the effect of SADReduces building costs in achieving light regulations
Reduces energy consumption
Hybrid LightingThe Hybrid Luminaires
A "hybrid" luminaire is a lighting fixture that contains both electric illuminants (such as fluorescent lamps or incandescent bulbs) as well as fibre optic illuminants. Often the fibre optic illuminant is a dispersing element that converts the highly directional fibre optic light into a more desirable distribution. Hybrid luminaires are available for both directional lighting and area lighting. A daylight harvesting sensor is used to maintain a constant amount of combined illumination resulting from the hybrid luminaire. When sky conditions result in a reduction in available sunlight, the hybrid luminaire can instantly respond by increasing the amount of corresponding electric light.
Current R&D Projects
1.Light Emitting Panels
2.Combined Light Technology
3.Range extension of transmission
Hybrid Lighting and Algae Growth
Algae FarmingOpen Ponds or Bio-Reactors
Requirements for Efficient Growth
CO2 / Nutrients / Light
Benefits of AlgaeUses 6% more CO2 in growth phase than in burning
Produces solid or liquid fuel Can be used as food
Can be used as nutrientsDoes not require land for food production
Can use sea water or dirty waterCan be produced at point of use
Theoretically can produce more output than any other bio-crop
