Hydro
• Should you have an application for
harnessing hydro energy. You are in great
luck as this type of renewable energy is the
most reliable, controllable and feasible
installation. In addition it is most likely to
have the shortest pay back period.
• A viable hydro application requires to have
a minimum hydraulic head of 3 meters.
Geothermal / Heat Pump
• Geothermal refers to the heat that is trapped in the
earth. In Ireland when people speak of geothermal
heating the are more often describing a broader
concept of heat pump application. Heat pumps can
be used to capture large quantities of low
temperature heat and convert it into smaller
quantities of higher temperature heat. This can be
achieved any where heat is available. The main
applications are from the Earth and ambient air or
water sources.
Wind
• Ireland has an
abundance of wind
energy. Almost any
location here will
provide more energy
than that of the best
located sites in
Europe.
• Utilizing energy from
the wind remains our
greatest obstacle.
• It is very expensive to
store electrical energy.
• The way forward is to
follow our European
neighbours and adopt
net metering.
Net Metering
• Net metering is achieved
when the electricity
created is synchronized
with the national grid. It
can then be connected
directly to the grid called a
grid tie installation. The
electricity provider
provides metering which
can meter energy flow in
both directions.
• When ample wind exists
the system may export
energy and conversely it
will import in times of low
wind. After an agreed
period has elapsed the
imported and exported
figures are computed to
determine the net import
or export, each of which
will be paid for at an
agreed rate. This negates
the need for storage.
Biomass
• BIOMASS is a very loose term in renewable
energy context, but generally it means utilizing the
energy from organic materials, crops and by
products such as chipped willow, grain, straw and
palletized wood shavings etc. Principally speaking
2.5 tons of biomass can substitute 1000 liters of
oil. Biomass may be even more attractive if you
currently produce some of the above fuels.
Solar
• Solar energy is
captured by every
surface that the sun
shines on some are
more effective than
others. Strong sunlight
can deliver up to 1 kw
of energy on each
square meter surface
area.
• Plants are by far the
most efficient
converters of solar
energy. To date only
two types of
technology are broadly
used in the capture of
solar energy. These are
solar water heaters and
photovoltaic cells.
Solar water Heaters
• This is the most common application.
• It is primarily used to heat domestic hot
water it can supplement approx 60%.
• The two main types are Flat plate and the
more efficient however not as aesthetically
pleasing Evacuative tube Solar panel.
• The have an unsubsidised payback period of
approximately 16 years.
Photo Voltics
• This technology converts the suns rays into
electrical Power
• PV systems currently cost approximately
six euro per watt.
• In addition to this they require batteries
and/or inverters to utilize their power.
• Their pay back is in excess of 20 years.
Hybrid Systems
• A hybrid system generally refers to a combination
of two or more technologies.
• The most common referred to is the wind/ PV
system which is configured to optimise energy
production in varying weather conditions.
• These systems have a wind turbine and Solar PV
feeding a common battery and or Inverter.
Anaerobic Digestion
• Natural gas is formed naturally by the decomposition
of organic matter in an Anaerobic (oxygen free)
atmosphere.
• Man has adopted and Improved this process for over
1000 years.
• Consequentially we know what conditions favour gas
production and we simulate these conditions in a
purpose built digester to produce and capture this gas.
• The decomposition of the matter in the digester is a
form of waste treatment and reduces the risk to the
environment.
