Wind turbine towers produced on demand

COBOD is a danish company focusing on automation in the construction industry by designing robotic 3D construction printers and automated processes for the building site. In 2017 COBOD 3D printed the first building in Europe – The BOD (Building On Demand) –  demonstrating that it was possible to 3D print a building according to European building codes.

The company has been investigating the construction of onshore tall concrete wind turbine towers, by means of 3D concrete printing (3DCP) with reinforced ultra-high performance concrete (UHPC). Indeed, 3D printing of towers – or pedestals for the towers – is relevant since the tower production cost increases exponentially with the tower size. As an example, the cost of going from i.e. 100 to 120 meters generally means that the production cost doubles. Further, 3D printing removes the high transportation cost of elements as well as the well-known highly restricting logistics constraints, which makes the use of towers with a base diameter greater than 4.5 meters virtually impossible unless (manually) cast at the site. This is both a very slow and costly process since the installation sites are typically at remote locations.

COBOD’s project focuses on providing the necessary and fundamental proof that 3D printing can be used to manufacture tall wind turbine towers and that this process is economically and technically feasible, receiving a principle approval from a third-party verifier. The result will be a 10-meter-tall pilot tower to prove the feasibility of the 3D printed UHPC with reinforcement.

Thanks to a fruitful and successful collaboration between COBOD and 1st Mile, the project has received funding for the next three years from The Danish Energy Agency’s (Energistyrelsen) Energy Technology Development and Demonstration Programme (EUDP).

Amager Bakke (ARC)

ARC’s project

The Amager Ressource Center is København’s famous waste-to-energy facility. Motivated by the ambition of the Municipality to become CO2-neutral by 2025, in 2019 ARC started investigating the possibility of applying carbon capture and storage/utilisation technology (CCS/CCU) to their waste-to-energy plant.

Waste-to-energy plants are particularly suited for CCS/CCU because they have many pathways to recuperate heat streams needed to operate and minimize the energy consumption in relation to carbon capture. The principle behind is to capture the CO2 from the smoke leaving the incinerators by spraying the smoke with a liquid that binds the CO2. Such a process enables to capture the CO2 and have CO2-free smoke leaving the chimney. The CO2 is then stored, but the long-term plan is to use it as a fuel replacing oil.

In February 2020, a study conducted and completed by ARC showed it is technically and economically feasible to couple CCS/CCU technology to its plant. This means that the 480,000 tons of CO2 emitted every year by ARC can be captured by the facility itself in a  cost-effective way, and thus deliver CO2 reductions at the lowest possible cost to the citizens.

“Despite all the efforts towards a green transition, there will continue to be waste, which is why we are looking for solutions that can reduce our CO2 emissions,” – Peter Blinksbjerg, chemical engineer and quality manager at Amager Resource Center

The ground-breaking ambition of this project is, in cooperation with DTU-CERE, Rambøll, and Union Engineering, to demonstrate that carbon capture at ARC can be done at net-zero energy consumption. In other words, the project aims optimize the energy consumption of every step of the CCS process to achieve the cheapest energy-consumption CCS process.

1st Mile’s work with ARC

The first step to implement the project is the demonstration of the technical and economic feasibility of the Carbon Capture technology, meaning that it is achievable at an acceptable cost both for waste producers and heat consumers (the citizens).

This is why the EUDP funding of DKK 30 mio that ARC was granted after collaborating with 1st Mile, have a key role for demonstrating the feasibility of cost-effective carbon capture on waste-to-energy plants, and mark a critical milestone and decision point for full-scale deployment of decarbonization of the waste-to-energy industry, in Denmark, Europe and globally. The final outcome of the project will be a decision base for ARC to decide upon an investment in a full-size Carbon Capture plant to capture all of the 480,000 tons of CO2 emitted by ARC every year.

“It’s fantastic. It will be the first of its kind in Denmark, and the prospects are enormous. It points in the right direction. ARC’s ambition is to manage waste in a completely carbon neutral way, making a serious and significant contribution to realizing the vision of the world’s first carbon neutral capital” – Jacob H. Simonsen, director at ARC

LED iBond

What is LED iBond’s Project about?

Founded in 2014, LED iBond International offers innovative solutions for integrating light and data, based on the company’s deep knowledge of modern LED technology and many years of development. LED iBond’s latest project develops around LED iBond’s flagship product Tracy®, which provides the lightest and thinnest LED panels available for commercial use today. Tracy® will serve as the base for a new smart LED infrastructure system for the green and smart buildings of the future, in order to support monitoring and real-time management of building energy consumption, temperature, ventilation, humidity, heating and a wide range of other building functions.

LED iBond expects that the project will expand the application potential of Tracy® significantly.

1st Mile’s Work with LED iBond

1st Mile was involved in LED iBond’s business development at an early stage and after a successful collaboration it was able to successfully help securing funding for the project in the first attempt. This press release can be found here.

The project, named ”LED Light as IoT infrastructure for buildings and industrial applications” was awarded a grant of DKK 9.6 million, of which LED iBond will receive DKK 6.1 million over a period of two years, while the other projects partners will receive a total of DKK 3.5 million.

The EUDP grant is a seal of approval for our technology as well as our potential within smart buildings which is one of our core markets. The grant provides us with the opportunity to speed up development of our core products, which will put us further ahead of the competition. We are grateful for the trust that EUDP has shown us with this grant”  –  Rolf H. Sprunk-Jansen, CEO of LED iBond International.
