Heliocentris orders Acta's EL100

Acta S.p.A.

("Acta" or "the Company")

Heliocentris orders multiple units of Acta's HG100 electrolyser

Acta S.p.A. (AIM: ACTA), the clean energy products company, is pleased to announce that it has received a blanket order for multiple units of its HG100 hydrogen generator from Heliocentris Energy Solutions AG ("Heliocentris").

The expected total value of the order once concluded is approximately €150,000 depending on the product mix and Acta expects to complete delivery of the units during the first half of 2013. Delivery against the order is subject to call-down of the units by Heliocentris based on market demand generated through Heliocentris' global distribution network for the educational market.

The HG100 is based on Acta's EL100 hydrogen generator which is easy and safe to use and is therefore ideal for Heliocentris' product range for educational institutions and laboratories. Acta has incorporated a number of modifications to the electrolyser to meet the specific requirements of Heliocentris' target market, including the development of a dryer module for high purity hydrogen production. The hydrogen generator, named HG100 and branded as a Heliocentris product, is being launched today at the Worlddidac exhibition in Basel and will be on display at Heliocentris' stand in hall 5.0 at booth No. D50 from 24th - 26th October 2012.

The Worlddidac is a Global Trade Fair for Educational Resources which is recognised as an essential meeting point for the sector and 30% of the world's wholesale trade in education resources.

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.

Paolo Bert, Chief Executive of Acta commented: "Acta is delighted with the continued interest from Heliocentris in our electrolyser products. This is further endorsement and recognition of our technology. It cements our already strong partnership and demonstrates the increasing demand in the market for low cost electrolyser technology which produces clean and dry hydrogen."

Ayad Abul-Ella, Chief Executive of Heliocentris commented:"Acta's HG100 hydrogen generator is ideal for integration into our educational products and applied research products. We are pleased to add the hydrogen generator to our growing range and look forward to showing the advantages of the technology to our educational market customers at Worlddidac Basel 2012."

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.
