supply comprises a mix of traditional
and renewable power sources, often
including battery storage.
The benefits of hybridization, in this
instance, are fuel savings, performance
improvements and reduced emissions.

Decarbonization is under increasingly urgent global focus as climate change research
and experience increasingly impact societies around the globe. As a result, we develop
the means and measures required to guide the international community towards cleaner
energy sources such as the international Sustainable Development Goals, the Paris
agreement, and International Maritime Organization regulations

The world is steadily, and quite quickly, diversifying its primary sources of energy. As we
transition from fossil fuels such as oil and coal, through natural gases and nuclear power
and further toward solar, wind and hydro, there’s an increasing need to overcome the gaps
produced when the energy demand exceeds energy supply - or when energy supply
exceeds demand.

Energy providers attempt to meet the
ever-changing supply and demand
requirements as closely as possible.
However, external factors, such as
the weather (in relation to renewable
sources of power) and the needs of
industrial customers (with inherent
changes in peak demands), make the
balance of energy supply and demand
quite challenging. This is where
hybridization comes into play.

Hybridization at a glance

A simple and broad
definition of
hybridization is any
system with two
or more sources of
energy acting together to accomplish
a task. A hybrid power supply system
could include a combination of
multiple energy sources, for example
solar power, batteries, and LNG. One
of the most commonly recognized
forms of hybridization today is the
distributed grid, where the mains power

In the world according to Danfoss
Drives, the definition of hybridization
can be summed up by introducing a
means of energy storage into a system.
Hybrid solutions are implemented
primarily for at least one of these
reasons:

Opportunity to sell more energy from

renewable sources to the grid

Reduce total cost of operation (TCO)

over the lifetime of the system by:

- avoiding over-dimensioning a system

- deferring investment in infrastructure
In over-supply situations, the hybrid
system can store the surplus energy.
When demand levels are high,
the stored energy can then be used
again to provide an additional source
of energy

Reduce operating expenses (OPEX)

- improve system efficiency

- increase system availability
Hybrid systems can increase system
efficiency and avoid power outages
caused by grid instability;

Decrease downtime of the system

by increasing robustness in the
case of power-quality issues.

Hybrid
configurations

The illustration
shows how some of
these systems can
be arranged. The size
and layout of each
hybrid system varies
greatly depending
on the application.

Multiple sources
can supply energy
to the application,
for example mains
supply, local
renewable energy
source, and energy
storage in the form
of batteries, super
caps or other form
of energy storage.

Energy storage directly connected to the AC grid using
a grid converter

This reduces the component count and size of the system and improves efficiency.
