First Orders Received for 1m3 Electrolyser Stacks

Acta S.p.A. (AIM: ACTA), the clean energy products company, is pleased to announce that it has received the first two orders for its 1m3/hour hydrogen generator stack. This is largest electrolyser stack unit currently produced by Acta, and is sold at a list price of €9,500 each.

The first of the orders is from the Spanish National Research Centre for Energy, Environment and Technology (CIEMAT). The centre is a public research organisation and part of the Spanish Ministry of Research, Development and Innovation. It focuses primarily on environmental and energy technologies, working closely with other national R&D institutions, universities and companies to support the industrial application of technologies for the achievement of environmental and social objectives.

The second order is from a German electrolyser manufacturer which is seeking to integrate Acta's hydrogen generator stack into its product range.

Deliveries of these two orders are scheduled for December 2012 and the Board believes that the two customer evaluations due to be carried out simultaneously by the national research institution and an industrial customer will provide important technical and commercial validation of Acta's breakthrough technology and may give rise to significant commercial opportunities. The Company is currently negotiating a number of additional sales proposals for its 1m3 electrolyser stacks.

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.

About CIEMAT

Formed in 1951 as the Nuclear Energy Board (JEN), CIEMAT conducts R & D in the area of energy. At present the main lines of action are the study, development, promotion and optimization of various energy sources including renewables, fusion, fission and fossil fuels, the study of their impact on the environment, and the development of new technologies, as well as key research areas such as high energy physics and bio-medicine.

CIEMAT's mission is to contribute to sustainable development in Spain and the quality of life of its citizens through the generation and application of scientific and technological knowledge, and its objective is to maintain a position as a centre of excellence in the scientific and technical areas in which it operates.

CIEMAT is geographically diversified with a team of some 1,400 people. While a significant part of the staff is based at the headquarters in Madrid, staff also work in Andalusia at the Plataforma Solar de Almería (PSA), a large internationally recognized scientific facility in solar technologies; at the Centre for Renewable Energy Development (ASSIGN) and the International Centre for Environmental Law (Cieda) in Soria; at the Extremadura Center for Advanced Technologies (CETA) located in Montreal; and at Barcelona at the Sociotechnical Research Center (CISOT).
