Danfoss will participate in the next International Energy
Agency (IEA) conference in Rotterdam on May 2017 to paint
the vision of the new role for supermarkets as enablers of
the energy transition. Under the title of the "Integration
of the hidden refrigeration capacity as heat pump in smart
energy systems," we will describe an innovative future,
based on state-of the art technologies that help to
integrate higher shares of renewable energy into the energy
The challenge of integrating more renewable energy,
primarily wind and solar, is that the elements can not be
controlled. A person can't make the sun shine or the wind
blow at a certain point in time, such as when they want to
charge our phone. Electricity generated on windy nights and
sunny days needs to be stored so it can be used when it's
needed. The ability to do this, namely, to provide
flexibility for the energy system and storage, is called
demand response. There is a solution available today. Thanks
to the potential of supermarkets, the excess capacities of
their refrigeration systems can be unlocked, via a heat
pump, to offer the required flexibility to the energy grid
of the future.
The traditional refrigeration system that keeps your pizza
frozen and your lettuce fresh carries the potential to
create a more sustainable energy mix for the communities of
tomorrow. Danfoss is ready to enable this transition through
innovative solutions and sophisticated technology.
Using existing technologies in new and innovative ways, such
as a supermarket's refrigeration system to create
flexibility in the energy system, is of the utmost
importance, according to a World Economic Forum report on
Grid Edge Transformation.

provides the innovations necessary to create electrical
and thermal energy storage capabilities with
supermarkets. These solutions will enable supermarket
systems to go beyond normal waste heat recovery and
become decentralized heat producers that can export
excess heat to connected thermal networks. As
supermarket refrigeration systems are dimensioned for
"the hottest day in a ten-year period," the normal
refrigeration system has substantial surplus capacity -
up to 70% of which can be utilized to supplement
external energy systems.
Future supermarkets are not only excellent new business
cases for their owners in terms of energy efficiency,
but they are also good for the environment. Supermarkets
can obtain up to 40% cost and emission savings by
leveraging the full potential of their refrigeration
system in the context of variable electricity prices.
Accumulated CO2 savings can be in the range of 60-70%.
With innovative solutions, Danfoss keeps people,
products, and the planet cool.
