Mexico: Solar Process Heat Beats Fossil-Fuel Boiler in Energy Cost

Inventive Power MexicoMexican company Inventive Power helps industrial customers to reduce their energy costs, which in turn reduces pollution in major cities. “Besides traffic, industrial boilers are responsible for much of the pollution in urban areas,” Ángel Mejía Santiago explained during the Intersolar Europe. The founder and CEO of Inventive Power emphasised that concentrating solar systems could offer energy at significantly lower cost than thermal power generation by natural gas or oil. Santiago sees great market potential in the technology, as there have been 32,000 boilers and water heaters installed across the country – at hotels and hospitals as well as food and beverage companies.

Denmark: Solar Concentrating Systems to Offer Wide Array of Uses

Submitted by Baerbel Epp on June 20, 2016
Aalborg Tars InaugurationAt present, the Danish turnkey supplier of concentrating solar systems, Aalborg CSP, has two more large projects under construction. Both installations – one for Danish district heating company Brønderslev Forsyning and one for Australian vegetables producer Sundrop Farms – cover electricity and heat demand at their sites. Yet another first-of-its-kind project was inaugurated in August 2015 in the Danish village of Tårs (see photo), 30 km north of Aalborg. It entailed 4,039 m² of parabolic trough collectors and a preheating flat plate collector field of 5,972 m². Simulations have pointed to a 31 % coverage of annual heat demand even without seasonal storage, since overheating in summer can be avoided by moving the parabolic trough collectors out of focus. Aalborg CSP is an experienced planner of steam and boiler systems and has been offering concentrating solar solutions since 2007.
