World energy demand is growing exponentially and the paths to meeting it are many. Steadily, and quite quickly, the world is 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 towards renewable sources dependent on whims of weather, there’s an increasing need to overcome the gaps which arise when the scales of energy supply and demand are out of balance.
Hybridization in the form of energy storage is one of the leading recent technologies and is rapidly becoming a megatrend. Energy storage offers us flexible ways to make supply and demand meet.
Energy storage is often described as a key enabler for integrating renewable energy into power generation. Danfoss is also widening the scope of energy storage to optimize energy consumption.
The VACON® NXP variable frequency converter offers a powerful performance in extreme conditions and provides a versatile and reliable solution for hybrid energy applications.
With energy consumption expected to increase one third by 2035, we are meeting the challenge of matching supply to demand by drawing on the best technologies we have in generation, distribution, and efficiency in consumption. The solutions we need exist today and there is enormous potential to implement energy efficient technologies: 63% of energy saving potential is found in industry and buildings and 90% of buildings in the EU have not been renovated for energy efficiency. At the same time, it’s documented that GPD increases by 1% annually as a direct result of introducing energy efficiency measures.
‘With the rise of renewables in much of the world, understanding and managing flexibility is becoming a cornerstone of energy markets.’ International Energy Agency, 2017
In the United States, energy losses in the electric transmission and distribution system have fallen by more than 25% since 1980. And collective energy use reductions of 40-60% relative to current forecasts are predicted by 2050.
To address fast-rising energy demand, Southeast Asian countries are increasingly pursuing energy efficiency policies and have agreed on a collective efficiency target of reducing energy intensity by 30% by 2025 compared with 2005 level, in addition to national targets in some countries.
In 2017 the global energy storage market is expected to grow 47 percent from the already record-breaking year in 2016 in terms of new storage capacity deployed. So, market forces are propelling accelerated use of existing solutions and the development of new technologies too.
The increasing influence of renewables means that the energy system is rapidly evolving to accommodate decentralization.
Decentralization: With energy generation increasingly located decentrally at or near the customer site, energy providers attempt to meet the ever-changing supply and demand requirements as closely as possible. The vital technologies in achieving the balance are distributed storage, microgrids, demand response and energy efficiency measures.
Correspondingly, smart systems evolve to balance the grid and connect local energy generation with local consumption, evening out surpluses and deficiencies. Digitalization is a vital ingredient in facilitating the growth of decentral energy systems, enabling open, real-time, automated communication. We will increasingly employ smart metering, remote control and automation systems. Beyond the meter, optimization and aggregation platforms as well as smart appliances and devices will connect us even further.
Accelerating electrification of many applications traditionally fueled by hydrocarbons is critical to long-term carbon goals and will be a relevant distributed resource. We will increasingly convert to electric vehicles, smart charging and heat pumps, which in turn lend themselves to locally generated power.
The three trends of decentralization, digitalization and electrification have the potential to disrupt the conventional electricity system, and they reinforce each other in a virtuous cycle. The potential for disruption is further fueled by exponentially decreasing energy costs, innovative business models, and low asset utilization of the electricity grid.
Hybridization in the form of energy storage is one of the leading recent technologies and is rapidly becoming a megatrend. Energy storage offers us flexible ways to make supply and demand meet by bridging the lag between energy generation and consumption, dampening peak loads and bridging outages.
Using grid edge technologies and services, customers in the future energy system will produce, consume, store and sell electricity.
For customers in the future energy system, energy storage meets the challenges of unpredictability, such as the weather (in relation to renewable sources of power) and the needs of industrial customers (with inherent changes in peak demands). This is where hybridization comes into play.
A simple and broad definition of hybridization is any system with two or more sources of energy acting together to accomplish a task. Perhaps the most commonly recognized form of hybridization today is a hybrid vehicle where a conventional internal combustion engine propulsion system is combined with an electric propulsion system to create a ‘hybrid’ power train. The benefits of hybridization, in this instance, are fuel savings, performance improvements and reduced emissions.
Hybrid solutions are implemented primarily for at least one of these reasons: To
In over-supply situations, the hybrid system can direct energy toward storage. When demand levels are high, the storage medium can be accessed to provide an additional source of energy;
Hybrid systems can increase system efficiency and avoid power outages caused by grid quality problems;
Hybridization of systems is expected to continue to increase significantly across a wide cross section of land- and sea-based industry and commercial sectors, especially due to the reduction of battery costs and increases in energy density.
To implement hybridization in your operations, you can get help from Danfoss Drives to introduce a means of energy storage into a system. We provide personal support and other resources to help you gain more insight into hybridization where it’s relevant in your own applications. For example, you’re welcome to participate in our webinars.

Energy storage is often described as a key enabler for integrating renewable energy into power generation. Danfoss is widening the scope of energy storage and developing solutions that also focus on the optimization of energy consumption. By equipping both machines and entire processes with energy storage systems, it is possible to significantly improve power quality, and upgrade performance and overall efficiency.
The future energy system will provide additional roles for the grid, and incorporate many customer technologies. Danfoss Drives offers products, engineering, and testing solutions for energy storage in diverse hybridization applications, for example peak-load smoothing, black-start capability, back-up energy and time shifting in a range of industries:
