16/11/2012 10:15 | Acta have no connection to Altergy, but the news that Fuel Cell back-up or off-grid power was the only power source still going strong after Hurricane Sandy knocked out the power grid is a very significant piece of good news for the fuel cell market because even though on price it is already comparable to other back-up power options now the whole world can see it is the most reliable. The ACTA connection to back-up telecoms market comes in the form of their electrolyser for producing hydrogen on-site, the only one that can compete on price with bottled gas and is actually cheaper than bottled gas in the Asia markets that Acta are targeting, which is why Heliocentris and SEFCA have signed agreements with Acta to use their tech. "This installation will represent the first telecoms customer field trial of an integrated fuel cell back-up power system incorporating Acta's unique technology, and is the only system in the world able to offer the same functionality at a comparable price." ............ "On the basis of a five-year Total Cost of Ownership, the system is cheaper than diesel or battery-based alternatives, while incurring none of their environmental disadvantages. In addition, since the hydrogen used to power the fuel cell is generated onsite whenever it is required, the system suffers none of the logistical barriers (delivery of hydrogen or other fuel) often associated with fuel cell back up power units. This is particularly advantageous in remote locations and in markets with high hydrogen costs, such as in Australia and in South East Asia in general." Sefca recognises the Acta solution as a major breakthrough for us and our customers. It is the quantum improvement "disruptive" technological solution that we have been searching for. Uniquely, it is a solution that offers Sefca the ability to produce high pressure hydrogen on site, is designed to work with the variable power outputs of PV cells, and all at a relatively low cost. Sefca has been monitoring the Fuel Cell and Electrolyser markets closely in search of a product that can solve these issues and we are incredibly excited to distribute Acta Electrolyser. We see it as meeting our needs and providing the hydrogen breakthrough that the market in Australia has been waiting for." | swimhat | |
16/11/2012 09:18 | Is Altergy linked to alta? If not, then what is so special about alta's cell tower product if there are allready established competitors with similar products? | basti1302 | |
15/11/2012 14:52 | Another big tick in the box of fuel cells for back-up power in the telecoms sector ........... makes the SEFCA field trials for producing on-site hydrogen with Acta's electrolyser even more interesting. "Altergy has been informed by some of its customers that the only wireless cell tower sites that remained up and operating during the power outages that followed hurricane Sandy were those powered by Altergy's Freedom Power fuel cell systems. Telecom carriers reported that numerous cell tower sites became inoperable due to loss of power, rapid depletion of battery backup power and failure of diesel generators to start. Wireless customers powered by Altergy's Freedom Power Systems were still able to make calls, contact emergency services, etc., during the prolonged outages." | swimhat | |
15/11/2012 09:30 | So why invest in ACTA? Hydrogen is the most abundant element in the universe, yet electrolyser technology which produces hydrogen from water faces two major barriers: cost, and energy efficiency. Until now. More than a hundred years ago aluminium was one of the most precious materials, only available to kings and queens. This was until the late 1880s, when the Hall-Héroult process was developed to produce it so cheaply that it became abundant. Today aluminium is accessible to everyone. There are currently two conventional methods of electrolysis (PEM and alkaline), and now Acta offers a third. It is this third method which has the potential of doing for hydrogen what the Hall-Héroult process did for aluminium. Hydrogen plays a crucial role in the renewable energy mix, and it is for this reason that Acta has been focusing on cost-effective and efficient hydrogen generation, with the clear goal of bringing this technology to the mass market. After six years of R&D and acquiring patents, Acta has refined and developed a groundbreaking technology with products ready for commercialisation and mass adoption. The product range includes Alkaline Electrolyser Stacks (AES100 to 1000) for electrolyser manufacturers, as well as electrolyser units (EL100 to 1000) for systems integrators and onsite hydrogen production. The products are compatible and perfectly suited for applications such as backup power, energy storage, and light vehicle refuelling. Simplicity and no noble metals Hydrogen production from electrolysis today is expensive and energy-inefficient. But Acta's AES technology solves both problems: the use of an alkaline solid polymeric membrane eliminates the need to use expensive and rare noble metals on the electrodes, and enables the safe production of directly compressed hydrogen without recourse to post-compression or sophisticated pressure balancing systems, which add to the complexity and cost. The system is intrinsically simple, also saving the power required for the ancillary devices and for the compressor. An important feature of the Acta system is that it strongly assists commercial adoption since it is not dependent on the supply of highpurity water, and is very tolerant in relation to competing technologies. Off-grid hydrogen opportunities The AES stack can be directly connected to an off-grid intermittent power source, such as solar panels or a wind generator, to produce clean hydrogen. At the heart of the AES technology is a significant intellectual property portfolio centred on Acta's alkaline membrane-electrode assembly (MEA) technology, developed through six years of research. Acta's AES versus alkaline and PEM electrolysers So how does Acta's AES technology really compare to conventional electrolyser systems? The AES stack technology combines the benefits of a liquid alkaline electrolyser with those of a PEM membrane electrolyser. As in the alkaline system there is no need to use noble and rare metals at the electrodes, reducing costs and making the technology feasible on a gigawatt scale for global commercialisation. But as in a PEM system, the hydrogen can be safely produced compressed beyond 30 bar (435 psi), with no need for caustic electrolyte, powered directly by intermittent renewable energy. Acta's alkaline solid polymeric membrane creates a physical barrier between the hydrogen and oxygen such that they can never mix in an explosive ratio unlike liquid alkaline electrolysers, where gases will blend across the porous separator when the current fluctuates, making them unsuitable for powering directly from intermittent renewable energy and for pressures beyond 67 bar (90100 psi). Liquid alkaline systems are generally used at ambient or low pressures, and to get higher than 67 bar requires post-compression and complex pressure balancing systems. Additionally, in Acta's technology there is no water transport through the membrane, reducing system complexity and cost, and permitting a simple, low-cost and efficient system. In a compressed alkaline liquid electrolyser, caustic KOH/water solution circulates under pressure at both electrodes, requiring a complex gas-water separator, pressurised solution pumps and circuit, and a KOH trap. The PEM system is simplified since distilled water is circulated only at the anode (oxygen) side, which is kept at ambient pressure. However, water is transferred to the cathode by the H+ proton as it crosses the membrane, and thus requires a water-hydrogen separator, a water recirculation system, and drying of the hydrogen. In Acta's AES stack, water is circulated at ambient pressure at the anode, requiring only an inexpensive water pump and soft plastic hosing. In addition, there is no liquid water transport to the cathode, which therefore remains dry except for a few ppm of vapour. Therefore the AES unit produces hydrogen that is already sufficiently dry and pure for most applications, and requires only a vapour trap for laboratory use. This contributes greatly to the simplification and cost reduction of the electrolyser system. Acta systems perform extremely well and at a low cost in comparison to other hydrogen technologies. When compared with low-cost electrolysers, for example, Acta's EL100 and EL200 units generate the highest pressure of hydrogen at the lowest cost among their competitors, and also lead the field in terms of hydrogen purity at the highest flow rates. At high volumes of hydrogen, the company's EL100 and EL500R are leaders in terms of offering high flow rates at high purity at very competitive prices. These strong technical benefits give Acta's products a distinct commercial edge. Indeed, a number of applications would not be commercially viable without Acta's priceperformance ratio, which underscores the growing interest from across the industry for the technology. The product range Acta is focusing on its product range including stacks for electrolyser manufacturers as well as complete electrolyser devices for systems integrators and hydrogen end-users. AES stacks Acta's AES stacks (AES100, AES200, AES300, AES500, and AES1000) produce dry, pure and compressed hydrogen at 30 bar. The hydrogen purity levels are 99.94% at 30 bar without a purification system, or 99.999% with the optional purification system. The stacks can be used in electrolysers for the distributed generation of hydrogen in domestic, industrial, and vehicle applications, combined directly with intermittent renewable energy. The water can be supermarket grade, demineralised water, or even rainwater can be used with the optional rainwater module for entirely independent offgrid systems. EL electrolyser range Acta's EL generators produce hydrogen on demand from water, directly compressed, dry and pure through a patented electrolytic process. CE-certified, low-cost, safe and highly efficient, it provides the ideal refill for fuel cell applications on the market. The EL water electrolyser demonstrates the great potential of the AES stack technology and simplicity of design. Acta EL water electrolysers can be powered by AC or DC for direct connection to renewable power sources. The electrolyser product range includes the EL100, EL200, EL300, EL500, and EL1000 systems. Entering the market As the hydrogen market matures, particularly for backup power, light vehicle refuelling and storage, Acta is seeing increasing interest in its technology. Light vehicle refuelling Acta has an agreement with Asia Pacific Fuel Cell Technologies (APFCT) in Taiwan to develop and supply hydrogen refuelling systems for light vehicles. This agreement is indicative of the opportunities in this sector, which includes bikes, scooters, and light four-wheeled vehicles. APFCT plans to expand its production of fuel cell scooters rapidly within the global scooter market, which currently stands at over 50 million units produced per annum (of which 75% are sold in China, India, and South East Asia). While the majority of e-scooters and e-bikes are currently battery-powered, it is expected that the numbers of fuel cell bikes and scooters will grow as their economics become more compelling. In addition, Acta's first project was recently launched between Hawaii-based Aloha Motor Company a joint venture by H2 Technologies and APFCT for the world's first commercial off-grid solar hydrogen refuelling station, in Honolulu [see page 7]. The hydrogen station uses solar power to drive the electrolysis of water, generating hydrogen. The 500 litre/h electrolyser was supplied by Acta to provide a convenient vending-machine hydrogen refuelling system for the scooters. Energy storage A renewable energy economy is impossible without storage, and hydrogen storage is currently the 'holy grail' for meeting the storage demands of intermittent renewable energy technologies. In the future, intermittent predominately solar or wind power systems are likely to require energy storage for a period of time stretching from a few days to a week or longer, whether they are on- or off-grid. To achieve this energy storage, the conversion of electricity to chemical energy is attractive, since chemicals are usually inexpensive to store. The most attractive chemical for this process is likely to be hydrogen, generated locally by electrolysis of water using excess intermittent solar or wind power. The hydrogen can subsequently be used to regenerate electricity via an engine or fuel cell. While hydrogen electricity storage is less energy-efficient (4050%), than battery or compressed air storage technologies, it offers far lower costs of storage capacity. (The overall efficiency is more like 30%, i.e. 60% efficiency for the electrolyser × 50% for the fuel cell.) Thus Acta's products have opportunities in renewable energy storage and micro-distributed peak power saving, with the AES1000 and EL1000 5 kW electrolyser products producing directly compressed hydrogen for maximum energy efficiency. Acta has a licensing agreement with Heliocentris, providing a strategic commercial partnership for the German market currently the world's largest solar market, as well as having a significant number of off-grid homes. Heliocentris specialises in autonomous energy supply and energy efficiency solutions with the aim of replacing diesel generators with zero-emission products. Its Clean Energy business offers a one-stop shop for fuel cells, hydrogen storage and power electronics, for off-grid, backup power and auxiliary power applications with low and zero emissions. Acta is included in Heliocentris' commercial product catalogue. Backup power systems Power consumption is a general problem for all telecom companies. The difficulty for most telecom operators is the hydrogen itself, and the need to source, store, and deliver what at the moment is a specialty chemical in heavy cylinders to remote base stations. This is the 'hydrogen barrier', and currently presents a major obstacle to the adoption of fuel cells in this application. The hydrogen barrier has led to the stalling of a number of projects in regions with unreliable grids, but Acta's solution promises to overcome this. Onsite generation of hydrogen removes the service cost and logistics problems encountered when handling hydrogen or any other fuel. Furthermore, thanks to its tolerance of the purity of the water supply, the company's electrolyser can be rain-fed for service-free operation. With Acta's solution, the longer replacement period and lower five-year total cost of ownership, fuel cell storage systems strongly outweigh the lower upfront costs of diesel and battery systems. For a systems integrator, the benefits of Acta stacks lie in their ease of UPS integration, their compact size and low cost, and for the endcustomer, their service-free operation, which requires no hydrogen delivery. They offer extended runtime, lifecycle, and reliability. A significant opportunity is seen in the fuel cell backup power market for telecoms. Acta has recently signed a marketing and distribution contract with SEFCA, an Australian-owned company specialising in the design, supply, installation, and support of fuel cells for backup and prime power applications. The immediate commercial objective of the new partnership is to integrate Acta electrolysers into SEFCA's fuel cell backup power systems, and to distribute them to the major telecom operators in Australia and New Zealand. The Australian market is distinctive for its high cost of hydrogen supply and the logistical difficulties of fuel distribution to remote locations. This makes the market economics particularly attractive for onsite hydrogen generation using electrolysis. By incorporating onboard hydrogen generation via Acta electrolysers, SEFCA intends to reduce the service costs of its fuel cell backup power systems, in particular for telecom base stations. 'SEFCA's greatest challenge has been the cost and availability of hydrogen in Australia,' explains Martin Burns, CEO of SEFCA. 'Due to Australia's geographic diversity and small regional populations, delivering reliable power to regional and remote areas is a major challenge.' 'The Acta solution... offers SEFCA the ability to produce high-pressure hydrogen onsite, is designed to work with the variable power outputs of solar PV cells, and all at a relatively low cost,' continues Burns. 'SEFCA recognises the Acta solution as a major breakthrough for us and our customers. It is the quantum improvement 'disruptive' technological solution that we have been searching for.' | encarter | |
15/11/2012 09:16 | Mattjos ........ I disagree regarding the scooters, APFCT have come a long way in the 10 months or so since they signed an agreement with Acta and now there is a common standards agreement for fuel cells and hydrogen between Taiwan and China the market has opened up in front of them ............ but for me the most important point is that they have their Government behind them, don't underestimate the speed with which these Governments move ............ once the BETA test phase is over I think things will move quicker. The Government connection is another reason to like the SEFCA agreement as Martin Burns has some very nice Government connections. Having said that it's easy to get bogged down on one agreement and fortunately ACTA are not about one agreement growing slowly, they are about the sum of all agreements growing slowly (then hopefully growing quickly) and that's why this share has a very long way to go. I suspect there will be plenty more agreements to come that will keep adding to the list. I see Heliocntris are raising more cash at 6 a share to fuel their expansion. | swimhat | |
14/11/2012 23:58 | Thanks encarter. Assuming the consumer finds no other use for the canister then it looks like a nice closed-loop supply chain so up-scale costs should be reasonably easy to quantify and little allowance necessary for leakage from the system. Don't know enough about the legislation covering the transportation of hydrogen but, it is done simply enough by the likes of Linde & BOC in high pressure form so, in low pressure form it should have less onerous regulations covering it & could be shipped alongside other Non-Perishables in forecourt supply chains that run alongside petrol & diesel. The scooter itself lacks power. At 24v DC x 70Amps peak it's not actually any more powerful than an invalid carriage in terms of its ability to do work. It would need to go to 48v-72v & at least 125Amps peak to climb any sort of a hill but, it's early days and i can see it taking off ... I was amazed at the number of electric bikes & scooters i saw in Tel Aviv the last time i was there - the kids have really cottoned on to the cost-benefits of these and they are very trendy too. Has got real long term potential in many parts of the world but, its still early days and whether or not this methodology of employing Hydrogen comes to dominate is far from clear | mattjos | |
14/11/2012 23:04 | The scooter is my favourite. I want one. | encarter | |
14/11/2012 16:15 | the scooter project is only a showcase at this stage, as far as i'm concerned. Good PR of course but, i cant see much coming from it in the near-term other than raised awareness. The Telecom backup units look like they should slowly gain traction in various parts of the world and provide a slowly growing sales line. The welding project is too early to say. The Horizon alliance, assuming it is indeed Horizon, is very much the potential game-changer as it will result in volume sales and it is the sort of B2C product which could quickly capture the minds of consumers, early adopters, gadget freaks etc. | mattjos | |
14/11/2012 13:37 | swimhat .. that is the conclusion I also have arrived at because, just as yourself, I am unaware of any other such products out there from any other manufacturer & what Horizon have done there I would imagine is well protected also | mattjos | |
14/11/2012 13:18 | More evidence (in my head anyway) that the Exclusive Agreement signed in May is with Horizon ........... in the agreement we are told the following. "The contract is for the supply of Acta's alkaline MEA's for a consumer electrolyser to be used to refill small hydrogen cartridges for fuel cell applications." "consumer electrolyser to be used to refill small hydrogen cartridges" ........... the following link from Horizon says (call it page 2 next to the four hydrostiks and hydrofill) "THE FIRST & ONLY RECHARCHABLE FUEL CELL CARTRIDGE" Put the two quotes together and as some of us have been saying, if not Horizon then who? | swimhat | |
14/11/2012 10:13 | encarter why will we see a return of the bull market in 2013 ? | kcowe | |
14/11/2012 09:45 | ACTA, AFC, LLOY, TYR four of the eight stocks I now hold, all up in recent weeks and all showing me a healthy profit. We will see a return of the bulls in 2013 imho. | encarter | |
14/11/2012 08:39 | encarter ... "The markets will get better I already see the signsand 99% of stocks will go up" could you please enlighten me on the signs you see ! as for me it looks as if the markets are rolling over.......... | kcowe | |
14/11/2012 08:34 | 34S, just put it down to experience and move on. Do some research, find yourself a couple of undervalued companies to invest in and sit tight. The market will get better, I already see the signs and 99% of stocks will go up. | encarter | |
14/11/2012 08:18 | encarter Most of the buyers were topinfo and his friends, too weak to hold even for a week. | 34simon | |
14/11/2012 08:16 | Superb, I can't believe that these are still so cheap, must be a sign of the times. | encarter |
