Energy Globe Award

With more than 178 participating countries and over 2000 project submissions annually the Energy Globe Award is today's most prestigious environmental prize worldwide. It distinguishes projects regionally, nationally and globally that conserve resources such as energy or utilize renewable or emission-free sources. Award ceremonies are held all over the world. Prominent personalities as well as Energy Globe Ambassadors in 90 countries support the mission of Energy Globe. The activities of Energy Globe attract worldwide media attention - international TV stations report each year with approximately 1,000 hours of broadcasting time. The aim of the Energy Globe is to raise global attention on sustainable, everywhere applicable environmental solutions and to motivate people to also become active in this area.

National ENERGY GLOBE Award Spain 2017

Submitted by: HELIOVIS AG
Inflatable solar collectors made of plastic

HELIOVIS developed a lightweight pneumatic technology for solar concentrators which allows 55% cost savings and 40% CO2 reduction compared to the best parabolic trough technologies.

Initial situation
Various studies have shown that Concentrating Solar Power (CSP) offers great potential for commercial energy production in the desert regions of North Africa and the Middle East as well as in the arid southern regions of the United States and Europe. The main advantage of solar thermal power plants over photovoltaic systems is the option to integrate very economic storage capacity leading to a predictable renewable power source for peak- or base-load demand. However, current CSP technology solutions are still too cost-intensive. The current CSP solutions are not cost-effective enough to warrant their implementation. Conventional technologies are resource and energy intensive in construction, logistics and installation, leading to high costs and negative environmental impacts.

HELIOVIS developed a lightweight pneumatic technology for solar concentrators which allows 55% cost savings and 40% CO2 reduction compared to the best parabolic trough technologies. The HELIOtube is an inflatable cylindrical concentrator made of plastic films. Its full scale is 220 m long with a diameter of 9 m. It can concentrate light by a factor of 100 and heats the thermal receiver fluid to a temperature of 400 to 600° C, enough to provide steam to turbines for electricity generation. HELIOtubes will be manufactured by a fully automated roll-to-roll process and in large quantities from commercially available recyclable plastic films (instead of the current steel-and-glass based technologies). The rolled HELIOtube can be transported in a standard container and will be inflated at the site designated for the power plant. This offers significant competitive advantages in materials, production, logistics, and installation costs.

In the past, the supply of thermal energy by CSP has been economically feasible only for large plants. For small-scale applications the technology has been perceived as cost-ineffective. While the majority of solar power technology focuses on the generation of electricity, HELIOVIS, due to its cost-effectiveness, operates in the segment of thermal energy generation in which CSP has not yet been applied. Moreover, HELIOVIS sets itself apart from other players in the solar technology field by the scalable, transportable and modular design of the HELIOtube concentrators.

We are an enthusiastic supporter of the Energy Globe Awards and its aim to strengthen society’s awareness of the necessity for ecological change, by honouring outstanding best practice projects in environmental sustainability from all parts of the world. ADVANTAGE AUSTRIA is the official Trade Promotion Organisation (TPO) of the Republic of Austria and as a country we are proud of our success in green technologies. Our support of the Energy Globe Awards continues this tradition.
