This is not the first time that CSP and Ib Andresen Industri have collaborated. Already last year, Ib Andresen Industri delivered steel components for Aalborg CSP’s pilot plant in Brønderslev. Because of the positive results from the pilot plant, Brønderslev Forsyning is willing to invest in this much larger solar thermal facility.
“Since our deliveries last year, we have been in close dialogue with Aalborg CSP about how we could further develop and mature the structure, should the need for additional deliveries arise. This dialogue and other initiatives resulted in us becoming part of this very interesting project,” explains Carsten Damsgaard, Sales Manager, Ib Andresen Industri.
The new solar thermal facility has a rated output of 16.6 MW, which is much higher than the pilot plant’s rated output of 0.8 MW. Ib Andresen Industri manufactures and delivers the steel components that have to keep the parabolic trough reflectors and absorber tube in place to maximise system output. Per Aasted, Sales and Project Engineer for Aalborg CSP, has this to say about the collaboration:
“It is important for us to have reliable partners who are experts in their field. Ib Andresen Industri’s wide-ranging knowledge of steel enables it to deliver top-quality steel at the time agreed. And they were our natural choice because we were very satisfied with working together with them on the steel structure for the pilot plant in Brønderslev.”
What does Ib Andresen Industri deliver?
Ib Andresen Industri delivers support arms and the rotating structure which make up to the steel body to which the arms are attached, as well as the sectional steel components that keep the facility’s absorber tube in place over the reflectors.
The steel body itself is made of 600 tonnes of steel. The body will comprise two steel troughs that are first laser-cut and edge-bent and then bolted together on site. The body has a circumference of about 4 m and it is 12 m long. The parts will be galvanised before being delivered by Ib Andresen Industri to Aalborg CSP.
Ib Andresen Industri rolls, curves and assembles the support arms to ensure that the system’s reflectors can be positioned correctly in the parabolic troughs. There are 10 support arms for each trough, five on each side of the body. The steel bodies with the 10 arms are joined in series. Once the 12 bodies are assembled, a drive unit is mounted on the end. The drive unit adjusts the position of the parabolic troughs in relation to the sun.
“This order will bring several of our steel services into play. In-house, it will be a major engineering and coordination feat, and it will prove once again that we guarantee intelligent, value-creating steel solutions. Our know-how relating to steel and metalworking processes – which for this order include laser-cutting, edge-bending, roll forming, surface treatment and assembly, with just-in-time delivery – strongly demonstrates our capability as a business partner,” concludes Carsten Damsgaard.
The deliveries will be made over a 10-week period and will generate multiple millions of kroner in turnover for Ib Andresen Industri.
What is CSP technology?
CSP stands for Concentrated Solar Power and is a technology, which uses reflectors to reflect and concentrate solar rays onto an absorber tube filled with a heat-transfer fluid positioned over the reflectors. The fluid is heated up by the solar rays to more than 300°C, after which the heat is channelled to a combined heat and power plant, which converts the solar energy into electricity and heat for end-users.
The fact that the new CSP facility can generate electricity is a pioneering feature within this technology.
