thyssenkrupp introduces net-zero energy elevators
thyssenkrupp has showcased a new innovation in green mobility: a net-zero energy system which can be used for existing elevators.
Buildings – particularly large corporate buildings – are responsible for up to 40 percent of global energy consumption, but this breakthrough could put a huge dent in that number if adopted on a wide scale. It is hoped that it will also inspire other companies to create similar systems and make the urban world ever cleaner.
Elevator equipment has a long life cycle, and each lift is used potentially hundreds of times a day. They tend to remain in a building for at least 15 years, and can account for up to 10 percent of a building’s energy consumption. The concept of energy-creating elevators already exists, which convert the device’s kinetic energy into electricity that can be fed back into the building’s power grid. thyssenkrupp installed this system at the One World Trade Center in New York, and the energy created feeds the building’s lighting.
This net-zero energy concept takes clean elevators a step further, improving energy efficiency whether or not the lift is in motion. The design, which is easily installed in existing elevators, uses a ‘hibernation’ or ‘sleep’ mode when the lift is idle that reduces energy demand. The energy to power the lift when in motion can be gathered from solar panels, with some to spare.
The system has been tested thoroughly, with a particular focus on older buildings, to ensure retrofitting is viable and valuable. thyssenkrupp is continuing to work on smart products and technologies to improve life and the environment.
Andreas Schierenbeck, CEO of thyssenkrupp Elevator, commented: “Elevators are often overlooked in our buildings but are actually at the very heart of a more energy-efficient future for our cities. We are delighted to reveal today our progress in developing a new concept that can help deliver this vision and set the stage for the next generation of intelligent, energy-savvy innovation.”
He added: “If we are to meet the sustainability targets defined by countries and ultimately save our planet’s resources, authorities and private companies need to act collaboratively in implementing the latest technology solutions to deliver real energy savings. At thyssenkrupp, we are constantly evolving our game-changing technologies and solutions in order to best serve current and future urban mobility needs.”

Drax advances biomass strategy with Pinnacle acquisition
The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.
The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).
This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.
In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.
The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
