Working in a company of passionate and intelligent colleagues fills me with inspiration every day to continue our progress towards decarbonization. There are many topics connected to this progress, and this month, I am happy to introduce energy efficiency in low voltage motors, along with insights into creating the green hydrogen economy.
Without early action on efficiency the energy transition to net zero emissions will be more expensive and much more difficult to achieve, according to the International Energy Agency (IEA).¹ Stefan Floeck , Division President, IEC Low Voltage Motors, shares compelling insights on how ABB is pushing the boundaries of innovation with the introduction of IE6 Hyper-efficient SynRM motors, which achieve a 20 percent reduction in energy losses against comparable IE5 motors.
Alongside some of my team, I had the pleasure to attend the World Hydrogen North America 2024 conference in May and we found it another significant learning experience. I have shared some of my findings below on how creating the clean hydrogen economy needs a collaborative approach across the supply chain.
That applies not only to hydrogen, but to all topics that we encounter in accelerating decarbonization. Collaboration, teamwork and passion helps deliver the technology needed, so enjoy these stories with many more to come in our collective effort.

1. IE6 motors take energy efficiency to the next level
Stefan Floeck , Division President IEC Low Voltage Motors, ABB Motion
Pumps, fans, compressors and other equipment use around two-thirds of the electricity consumed by industry. That is why energy efficient motor technology is critical, both for productivity and for decarbonization initiatives to reduce the CO2 emissions related to generating electricity. In fact, if we could replace the 300 million-plus industrial electric motor-driven systems operating today with optimized, high-efficiency versions, worldwide electricity consumption could be cut by up to 10%.
It is good to see governments worldwide supporting this effort by introducing increasingly stringent efficiency regulations for motors. For example, the EU has its Ecodesign Directive, which since July 2023 has required IE4 "Super-premium" energy efficiency for many common types of motor in the range of 75 – 200 kW. Other countries and regions are following the EU’s lead.
However, for ABB it is not enough to just meet current legislation. We aim to be at the leading edge in technology, to ensure our customers always have access to the most energy-efficient motors. That is why we were proud to launch our "Ultra-premium" energy efficiency IE5 SynRM motors in 2019. In less than five years they have made a significant impact, enabling us to take over a quarter of the global market for low voltage IE5 motors. Building on that success, we have continued push the envelope even further by launching our Hyper-efficient IE6 motors that feature the same well proven technology.
How do we define IE6?
While there is currently no standard to define an efficiency class beyond IE5, we think it makes sense to base our approach on the "20% principle". Because, so far, each IE efficiency class has had 20% lower losses than the previous one. Therefore, we set ourselves the natural the goal that IE6 Hyper-efficiency will offer 20% lower losses than IE5.
Achieving IE6 with magnet-free SynRM technology
Synchronous reluctance (SynRM) motor technology combines the performance of a permanent magnet (PM) motor with the simplicity and service-friendliness of an induction motor. The rotor has neither magnets nor windings and suffers virtually no power losses.
SynRM motors are combined with variable speed drives (VSDs), making a SynRM package the ideal upgrade, especially as the motors are the same size as equivalent IE3 induction motors. This makes it easy to achieve a rapid return on investment (ROI) by replacing legacy motors with modern, high efficiency products.

The next logical step up from the success of IE5 was to develop our new IE6 SynRM motors. In use, they have around 50% lower energy losses than an IE3 motor, enabling significant savings across a wide range of applications.
Technology to fit customers’ needs
The magnet-free SynRM motors are just one element in ABB’s comprehensive premium portfolio of high-performance motors that incorporates over 140 years of domain expertise to ensure maximum reliability combined with a commitment to sustainability. Recognizing that a single technology is not the answer to all customer needs, we aim to master all motor technologies. That is why, in addition to SynRM, we have also achieved IE6 Hyper-premium efficiency with permanent magnet (PM) and PMSynRM technology - a hybrid technology launched in 2014 that pairs the SynRM design with a permanent magnet "boost".
With this latest generation of IE6 motors we are well placed to accelerate the global drive for increased energy efficiency and industrial decarbonization.
2. World Hydrogen North America Reflection
Nora Han, Ph.D. , VP, Hydrogen Product Group
Last month, we had the extraordinary opportunity to attend the World Hydrogen North America 2024 conference. This event brought together a passionate group of nearly 2,000 individuals dedicated to the green hydrogen economy.
The conference was a learning experience for all of us. We collectively recognized that the creation of a clean hydrogen economy needs a collaborative approach across the supply chain. It also requires us to undertake shared risks.
Crucial factors to success:
During the conference, I shared my insights on ABB’s role for taking on shared risks. Having followed the green hydrogen economy for four years now, I've noticed a substantial emphasis on the electrolyzers that produce green hydrogen. The performance of these electrolyzers directly affects the price of hydrogen. This has become a hurdle in increasing market demand and delaying projects for FID. But it's not just about the electrolyzer it is also all the electrical components that make up make up the electrolyzer system (i.e. rectifier, transformer, and switch break.)
How can technology efficiency affect energy use and cut costs?
According to the International Energy Agency (IEA)[2] if we improve our current energy efficiency by 2% per year over the next decade, we could save up to 95 exajoules (EJ) of energy per year. To put this in perspective, 95 EJ is equivalent to the total final energy consumption of the United States in 2022.
Through such improvements, we could avoid an added 5 gigatons (Gt) of CO2 emissions per year by 2030, compared with a scenario where policymakers make no additional major efforts.
Yes, it can be just that simple.
As mentioned before, my optimism is renewed after attending the conference, but it takes us all in the hydrogen economy to make it successful by taking on shared risks and uniting in collaboration.
