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. They are also applicable in non-fuel cell hydrogen and oxygen applications, including oxy-hydrogen gas welding systems, where the Company is generating significant commercial interest.

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.
