The Energy Catalyzer (also called E-Cat) is a purported cold fusion or Low-Energy Nuclear Reaction (LENR) heat source built by inventor Andrea Rossi, with support from physicist Sergio Focardi. An Italian patent, which was approved on April 6, 2011, describes the apparatus as a "process and equipment to obtain exothermal reactions, in particular from nickel and hydrogen". The device allegedly works by infusing heated hydrogen into nickel, transmuting it into copper and producing heat. An international patent application has received an unfavorable international preliminary report on patentability because it seemed to "offend against the generally accepted laws of physics and established theories" and to overcome this problem the application should have contained either experimental evidence or a firm theoretical basis in current scientific theories.

The device was demonstrated to an invited audience several times, and has been commented on by various academics and others, but has not been independently tested. Mark Gibbs of Forbes commented: "until a verifiably objective analysis is conducted by an independent third party that confirms the results match the claims there’s no real news".

Evaluation of the device

Rossi and Focardi are reported to have been unable to find a peer-reviewed scientific journal that would publish their paper describing how they claim the Energy Catalyzer operates. Their paper appears only in Rossi's self-published blog, Journal of Nuclear Physics. The device has been commented on positively by University of Bologna physics professor Giuseppe Levi.

The University of Bologna explicitly states that they have not been involved in the demonstrations and none of the experiments were at the university. University of Bologna researchers have attended some E-Cat experiments, but only as observers. The University will begin experiments on the E-Cat as soon as the contract signed with EFA Srl (Andrea Rossi's Italian company) is put into effect. On November 23, 2011, the Corriere della Sera reported on its Bologna edition that the University's contract with Rossi is expected to start "within a few weeks", and that the results of the research would be published in scientific journals, possibly "by summer ".

As Ny Teknik reports, Peter Ekström, lecturer at the Department of Nuclear Physics at Lund University in Sweden, concluded in May 2011, "I am convinced that the whole story is one big scam, and that it will be revealed in less than one year." He cites the unlikelihood of a chemical reaction being strong enough to overcome the Coulomb barrier, the lack of gamma rays, the lack of explanation for the origin of the extra energy, the lack of the expected radioactivity after fusing a proton with Ni, the unexplained occurrence of 11% iron in the spent fuel, the 10% copper in the spent fuel strangely having the same isotopic ratios as natural copper, and the lack of any unstable copper isotope in the spent fuel as if the reactor only produced stable isotopes. Kjell Aleklett, physics professor at Uppsala University, said the percentage of copper was too high for any known reaction of nickel, and the copper had the same isotopic ratio as natural copper. He also stated, "Known chemical reactions cannot explain the amount of energy measured. A nuclear reaction can explain the amount of energy, but the knowledge we have today says that this reaction cannot take place." According to PhysOrg (August 11, 2011), the demonstrations held from January to April 2011 had several flaws that compromised their credibility and Rossi had refused to perform several tests that could verify his claims.

Hanno Essén, associate professor of theoretical physics, and Sven Kullander, chairman of the Royal Swedish Academy of Sciences' Energy Committee, wrote in a report about the device "Since we do not have access to the internal design of the central fuel container and no information on the external lead shielding and the cooling water system we can only make very general comments." and "Any chemical process for producing 25 kWh from any fuel in a 50 cm container can be ruled out.".

Other reactions to the device have been mixed. Dennis M. Bushnell, Chief Scientist at NASA Langley Research Center, described LENR as a "promising" technology and praised the work of Rossi and Focardi. Roland Pettersson, retired Associate Professor from Uppsala University, who witnessed the Oct 6 demonstration said "I'm convinced that this works, but there is still room for more measurements". Skeptic James Randi, discussing the E-Cat in the context of previous cold fusion claims, predicts that it will eventually be revealed to not function as advertised. Commenting on an assertion made by Rossi, who said he was not ready for a full academic investigation of his technology because he doesn’t yet have full patent protection, the Dean of Science at the UML Robert Tamarin stated: "That’s consistent with it not working, but it’s also consistent with it working very well".

Theoretical astrophysycist Ethan Siegel and nuclear physicist Peter Thieberger argue that the claims for the E-Cat are incompatible with the fundamentals of nuclear physics. In particular, the Coulomb barrier for the claimed fusion reaction is so high that it is unsurpassable anywhere in the known universe, including the interior of stars. The reaction also would create gamma radiation that would penetrate the few inches of shielding apparently provided by the E-Cat; much more substantial shielding, i.e., "a foot of lead, a meter of concrete, or a few meters of water" would be required to prevent acute radiation syndrome in persons involved in the claimed 'demonstrations'. Given numerous other fundamental scientific inconsistencies – such as the ratio of isotopes in the supposed copper "fusion product" being identical to that in natural copper – the authors argue that it is now time "for the e-Cat's proponents to provide the provable, testable, reproducible science that can answer these straightforward physics objections. Given everything that we know, as others also demonstrate...it's time to set aside the mirage of Nickel + Hydrogen fusion and get back to work finding real solutions to our energy and environmental problems".

Yeong E. Kim, Professor of Physics and Group Leader Purdue Nuclear and Many-Body Theory Group of Purdue University wrote and presented a paper that proposes preliminary theoretical explanations of the reported results of the device.

Patents

An application in 2008 to patent the device internationally had received an unfavorable preliminary report on patentability at the World Intellectual Property Organization from the European Patent Office, noting that the description of the device was based on "general statements and speculations" and citing "numerous deficiencies in both the description and in the evidence provided to support its feasibility" as well as incompatibilities with current scientific theories. The patent application was published on October 15, 2009.

However, on 6 April 2011 an application was approved by the Italian Patent and Trademark Office, which issued a patent for the invention, valid only in Italy. International, European, and U.S. patent applications are still pending.

Demonstrations

The device has not been independently verified. Invited guests attended several demonstrations in Bologna. In January and February two demonstrations were given in the presence of Levi. In March two Swedish scientists witnessed a demonstration. In April some representatives from the press were invited, and two demonstrations followed in September and October. Of the January demonstration, Discovery Channel analyst Benjamin Radford wrote that "If this all sounds fishy to you, it should," and that "In many ways cold fusion is similar to perpetual motion machines. The principles defy the laws of physics, but that doesn’t stop people from periodically claiming to have invented or discovered one."

• January 14, 2011: The demonstration was monitored by independent scientists of the University of Bologna, including INFN physicist Giuseppe Levi. Levi concluded that the power and energy produced was "impressive," and that the Energy Catalyzer might be working as a new type of energy source.
• March 29, 2011: Two Swedish physicists, Hanno Essén and Sven Kullander participated as observers in a test of a smaller version of the Energy Catalyzer. The test ran for six hours, with claimed results of net power output of 4.4 kW, and total energy output of about 25 kWh. They were given samples of nickel powder, some unused and some that Rossi reported as used for 2.5 months. An analysis showed the unused powder was pure nickel while the used powder contained 10 percent copper and 11 percent iron, Kullander said that the presence of copper is "a proof that nuclear reactions took place in the process”. Iron production is not mentioned anywhere in the patent. In their test report, Essen and Kullander cautioned, "Since we do not have access to the internal design of the central fuel container... we can only make very general comments." In a later conversation Essén stated "I am still very uncertain about this."
• October 6, 2011: An E-cat was demonstrated, which reportedly lasted for about eight hours. Roland Pettersson, retired Associate Professor from the University of Uppsala, who witnessed it said "I'm convinced that this works, but there is still room for more measurements".

Commercial plans

Originally, a new Greek company, Defkalion, was to deliver a heating plant based on the Energy Catalyzer, but this deal was terminated. Since then Defkalion have announced that they plan to make a similar device.

In May 2011 Rossi reached an agreement with AmpEnergo, an Ohio company, to receive royalties on sales of licenses and products built on the Energy Catalyzer in the Americas.

On October 28, 2011, 1 MW plant based on the Energy Catalyzer was reported to have been tested by engineer Domenico Fioravanti for an undisclosed customer. According to Fioravanti, the plant released 2,635 kWh during five and a half hours of self sustained mode, an average power of 479 kilowatts – just under half the promised power of one megawatt. The customer reportedly acquired the plant after the test. Independent observers were not allowed to watch the measurements or make their own, and the plant remained connected to a power supply during the test allegedly to supply power to the fans and the water pumps. Rossi claims to have orders from customers in the US and Europe for thirteen more 1 MW units in addition to the undisclosed customer from the October 28 test. He offers these for sale for $2 million. The Italian popular science magazine Focus reports that 12 additional units are to the same, undisclosed customer, and quoted Rossi: "We are building a 13 MW thermal plant, made of 13 plant such as the one you saw on October 28th: but it's a military research and I can't reveal any further detail, not the name, nor the place, nor the nationality of the customer".

Ecat.com is a website for selling the device, run by four Swedish entrepreneurs, two of them particle physicists. Magnus Holm, one of the physicists, in response to a question about sceptical commentary regarding the device, replied that "Until makes an independent test, there is obviously a small chance that it does not work. We are willing to take that risk because it’s such an amazing technology if it works". When asked what his response was to suggestions that he was "contributing to fraud", he replied "We are not engaged in any deception, and I do not think Rossi is engaged in any fraud either. If it would turn out that it does not work, in spite of everything, I would think it is about self-deception".

On November 23, 2011, in the Massachusetts Statehouse, Andrea Rossi met with the minority leader of the Massachusetts Senate Bruce Tarr and representatives from the Massachusetts Institute of Technology, Northeastern University, and the University of Massachusetts, to explore the prospects for developing and manufacturing the device in Massachusetts, USA. According to Robert Tamarin, the Dean of Science at UML, the representatives were mostly skeptical and only examined the possibilities of manufacturing within Massachusetts in case the technology turns out to work.
