("Acta" or "the Company")

Peer Review Journal Publication

Acta S.p.A. (AIM: ACTA), the clean energy products company, is pleased to announce that a research paper prepared by the Company's scientists and describing the nature and benefits of Acta's core electrolysis technology has been published by the prestigious review journal, Angewandte Chemie International Edition.

Angewandte Chemie is one of the world's leading general chemistry journals, with an Impact Factor higher than comparable journals1. Publication of the paper represents a significant scientific recognition of the technology developed by Acta over many years and of the outstanding results achieved both within its research labs and in practical applications.

Through the published work, Acta's scientists have demonstrated that very high efficiency and stability can be achieved by an electrolyser without the aid of platinum metal group electro-catalysts and by using cost effective alternatives. Moreover, they showed that the system is effective for applications with intermittent power sources, such as renewable energy.

The paper has been published as a "Communication", which are papers that have been critically selected by the journal for publication following a detailed peer review and which report on the latest research results in chemistry. It will appear in printed form in a future edition of the journal.

Paolo Bert, Chief Executive of Acta, commented:

"This is the first scientific paper that we have produced on our technology and it has been accepted for publication by one of the leading general chemistry journals in the world. I would like to congratulate our scientific team on achieving this important recognition of their outstanding work."

Acta's research paper, entitled "Highly Efficient Platinum Group Metal Free Based Membrane-Electrode Assembly for Anion Exchange Membrane Water Electrolysis", has now been published online (http://dx.doi.org/10.1002/anie.201308099).

About Acta S.p.A.

Acta S.p.A. is a developer and manufacturer of a range of clean energy products. Based on its world-leading expertise in alkaline membrane technology, the Company has developed a unique range of low-cost, compact hydrogen generators (electrolysers) which produce pure, dry compressed hydrogen at high efficiency from renewable or grid power.

In April 2013 Acta launched the Acta Power, an integrated electrolyser and fuel cell system for use in back-up power and renewable energy storage applications. Best understood as a "Hydrogen Battery", the system converts energy from renewable or grid power when it is available and stores it in the form of hydrogen, and then converts the hydrogen back to electrical power when needed due to grid black-out or lack of solar / wind power.

This system has extensive application as a back-up power unit for telecommunications base stations, where it competes on cost against traditional battery and diesel solutions, while offering a cleaner solution and better service. In particular, the use of rainwater and the generation of hydrogen on-site removes the cost and logistical barriers of fuel delivery, while also avoiding the theft risk associated with diesel, methanol and battery systems.

The supply of fuel cell back-up power systems for telecommunications base stations represents a large and fast-growing market, especially in extensively bad-grid and off-grid locations such as in Asia and Africa. Battery sales to the Chinese telecoms industry are currently valued at $4.7 bn to $7.8 bn per annum (Fuel Cell Today, China).

Acta holds a portfolio of patents and patent applications on its key technologies, manufactures its products through a combination of production, component subcontracting, and final product assembly and quality control, and has established distribution channels through partnerships in China, India, SE Asia, Australia, Africa, Middle East, Germany, UK, USA and South America.

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