Acta's EL100 exhibited by Heliocentris at the Worlddidac Basel

Acta S.p.A. (AIM: ACTA), the clean energy products company, is pleased to announce that Heliocentris Energy Solutions AG (XETRA: H2FA) ("Heliocentris") will be exhibiting Acta's EL100 at the Worlddidac in Basel on 24 - 26th October 2012.

The EL100 is Acta's CE certified hydrogen generator which is easy and safe to use therefore ideal for educational and laboratory applications.

This will be a debut for Acta's electrolysers at the Global Trade Fair for Educational Resources. Worlddidac Basel is recognised as an essential meeting point for the sector and 30% of the world's wholesale trade in education resources is conducted here. The results of an independent visitor and exhibitor survey from Worlddidac Basel 2010, confirmed that the exhibition is an excellent place to feature new products, with 94% professional visitors and approximately 5 000 visitors who are international dealers, it provides a hub for products in the sector.

The EL100 will be part of Heliocentris' product range for educational institutions and laboratories. Heliocentris has an exclusive global license to sell Acta's products to the educational market and in return has committed to buying alkaline solid membrane electrolyser products exclusively from Acta.

Acta's EL100 can be seen at Heliocentris' stand in hall 5.0 at booth No. D50.

Paolo Bert, Chief Executive of Acta commented

"We are pleased to be able to exhibit the fruits of our strong partnership with Heliocentris. The partnership has enabled Acta to address significant markets for its products through the established sales channels which Heliocentris already has in place and we hope to continue to gain market share together."

Ayad Abul-Ella, Chief Executive of Heliocentris commented

"We are proud to present Acta's EL100 to the market at Worlddidac Basel 2012. This low cost electrolyser technology which produces clean and dry hydrogen is ideal for integration into our educational products and and applied research products. We are looking forward to showing the advantages Acta's technology provides to our Multi-Hybrid-Energy Systems to our worldwide customer base."

About Acta S.p.A.

Acta S.p.A. is a developer and manufacturer of a range of clean energy products. Its product line includes market-leading compact hydrogen generators (electrolysers) which produce pure, dry and compressed hydrogen in a way that is easy-to-use and completely safe, and the Company is committed to integrating its award-winning electrolysers with renewable energy sources.

Acta's cost-competitive electrolysers are based on its proprietary, inexpensive environmental catalyst and hydrogen conversion technologies. These products help overcome the barriers to the adoption of fuel cells, most notably the lack of a local hydrogen infrastructure.

Acta's low-cost hydrogen generators represent a unique breakthrough in electrolyser technology. They can operate using mains power or intermittent renewable energy, and produce clean, dry hydrogen already at pressure for use in fuel cell and other applications. This unique combination of features avoids the system complexity and energy cost of further cleaning, drying and compression of the hydrogen, resulting in a simple, compact, low-cost and highly efficient system that is ideally suited for energy conversion and storage applications. In such applications, which include battery replacement and renewable energy storage, low cost and high efficiency are critical to commercial viability, while hydrogen compression is essential for the energy density of the system. No other water electrolyser currently on the market offers this combination of benefits.

Acta is focusing on delivering its products to markets with high volume demand for high-value environmental solutions (transport, back-up power, energy and leisure). It is accelerating the commercialisation of its products via partnerships with original equipment manufacturers (OEMs), distributors, and agents in these sectors, and intends to drive down production costs at high volume via contract manufacturing.

Acta S.p.A. is based near Pisa, Italy, and was admitted to trading on AIM in October 2005.
