ABB’s energy-efficient technology reduces CO2 emissions

The electricity sector is facing an ever greater challenge – it is necessary to provide enough energy for the growing world population, but it is also crucial to reduce greenhouse gas emissions in order to stop global warming and mitigate the climate crisis.

And while world leaders are making plans to reduce pollution at the Glasgow summit, it is important to know that some solutions, which we can implement immediately, we already have, and come in the form of two magic words – energy efficiency.

Rational use of energy today is not an option, but an obligation, and ABB offers us technology that allows us to save electricity, not from 2030 or 2050, but from 2021.

As 45 percent of the world’s electricity is used to power electric motors in buildings and industrial applications, it’s clear why ABB saw the space to achieve energy efficiency right there.

Electric motors are an integral part of everyday modern life. While we may not see them, they power the pumps that supply us with fresh water, run ventilation and air conditioning systems that cool us, and operate the sheet metal-forming presses for our car bodies. Also, they enable sustainable transport and are widely used in food production.

The challenge lies in the fact that too many motor-powered systems in the world are based on outdated and inefficient energy-wasting technology. That’s why energy-efficient engines will be controlled frequency regulators, play a major role on the road to zero CO2 emissions.

“Investing in the latest energy efficient technology can have a big impact. Research shows that global electricity consumption could be reduced by up to 10 percent if 300 million electric-powered industrial systems worldwide are replaced with optimized high-efficiency equipment. This represents more than 90% of the annual consumption of the entire EU, ”said Morten Wierod, President of ABB Motion.

Achieving energy efficiency in southern Europe

ABB is at the forefront when it comes to technologies that are already helping customers across southern Europe use less energy and reduce carbon emissions.

In one of the most populated cities in France, the local waterworks has completed a major project to renovate the city’s drinking water and sanitary water pumping stations. By renovating more than a hundred pumping systems, equipped with ABB high-efficiency IE4 motors, they have improved the overall electrical performance of the network by seven to ten percent.

HPP Bajina Basta, the second largest hydropower plant in Serbia, will improve availability and increase overall energy efficiency. Thanks to ABB MEGADRIVE-LCI (~ 21MW) and transformers for starting 2 x 315 MW synchronous machines in a reversible hydropower plant, ABB helps the entire HPP increase energy production by delivering an additional five to six GWh per year, with greater efficiency and operational readiness of hydro turbines.

IKEA has improved the energy efficiency of its two largest stores in Spain by installing solar panels and equipping air conditioning systems with fifteen ACH580 frequency converters with reduced harmonic emissions, as well as standard ACH580 and ACH550 frequency converters.

Upgrading the HVAC system resulted in a 25 percent energy saving for IKEA stores in Alcorcon and San Sebastian de los Reyes. These savings relate to an annual reduction in CO2 emissions of approximately 425 tonnes, which is equivalent to the annual emissions of 95 cars.

The Italian company, Farina Presse, has developed a new KERS (Kinetic Energy Recovery System) press used in heavy industries, such as metal. The system is equipped with a motor that renews energy via an ABB regenerative regulator, reducing consumption by more than 40 percent. The energy consumed by a standard press in the form of dissipative heat is 388,000 kWh: the KERS press eliminates 300 tons of CO2 emissions. In order to absorb this amount, 4,500 trees would need to be planted.

The world’s first zero-emission all-electric tugboat, called the Zeetug30, was launched at the port of Istanbul in Turkey.

ABB has contributed to this with 14 HES880 mobile drives: six DC / DC converters, two inverters for each dual-winding propulsion motor, one inverter for each bow thruster and fire pumps, as well as two 150 kVAoff-grid converters for tractor auxiliary drives . With this configuration, the Zeetug30 saves approximately 210 tons of CO2 and 9 tons of nitrogen oxide emissions per year, compared to diesel-mechanical tractors of similar size.

Italian OEM Sacmi Packaging and Chocolate has analyzed a typical homogenization cycle for high-quality dark chocolate produced in a factory operating approximately 7,000 hours per year, and estimates that replacing IE3 motors with ABB’s IE5 synchronous reluctant motors provides 3-4 percent energy savings, while reducing emissions CO2 for as much as 22 tons per year.

“These examples firmly demonstrate ABB’s commitment to climate protection in close synergy with our customers in industry and infrastructure,” said Alessandro Pueroni, ABB Regional Motion Business Manager for Southern Europe and Italy. “One of the cornerstones of our 2030 sustainability strategy is a commitment to reducing greenhouse gas emissions from customers by more than 100 million tons, in close cooperation with institutions, governments and universities. In this regard, we call on all stakeholders in our countries, including businesses and the media, to work together to combat climate change and join the energy efficiency movement. “
