Angstrom Advanced Inc was invited to Minneapolis, MN to speak about the future of using Hydrogen (Steam Reforming and PSA technology) to improve Biomass development and economy, at the 2013 International Biomass Conference and Expo.
“Today we focus on hydrogen-from-biomass. As a renewable energy source, biomass can either be used directly, or indirectly—once or converted into another type of energy product such as bio-fuel.
By processing biomass through various routes, we can get lots of products such as bio oil, biogas, biodiesel, ethanol… but it’s better to transform them further to hydrogen through reforming reaction while collecting the carbon dioxide meanwhile.
The most important reason we adopt hydrogen as final energy carrier instead of other forms is the inherit properties of hydrogen:1) clean, 2) inexhaustible, 3) high energy density. ” More articles will be released about using Hydrogen in Biomass projects. Please pay attention to our press releases.

North America Clean Energy, the leading magazine and internet media in Renewable Energy sector published again an article from us about our innovative collaboration of Hydrogen and Biomass technology. “A new application of hydrogen is being deployed which is helping solve humanity’s ever-evolving energy woes. Traditionally, hydrogen has a large number of applications – used in everything from industrial products to food packaging. Ammonia used in fertilizer and industrial processes amounted to 160 Million tons worldwide in 2011; hydrogen is a primary component in ammonia. The market demand for new, less expensive sources of hydrogen is driven heavily by fertilizer and manufacturing, however, a new market demand is emerging for hydrogen in another sector – energy. Power plants in Germany as well as Canada (using wind and natural gas, respectively) are today supplementing their primary electrical generators with advanced configurations of hydrogen technologies. These retrofits help the plants save money by smoothing supply, converting excess electricity generated into storable hydrogen gas which can be returned to electricity using a turbine generator or a fuel cell. ” (The drawing is referred to a famous biomass manufacturer, Nexterra)

A Profitable, Clean Tech Solution to Grid Congestion in China
Boston,MA United States
Angstrom Advanced Inc has paid a lot of attention to what is going on in China, especially the renewable energy section. The leading magazine “Energy Digital” recently published an article from Verde about this market opportunity:
“As China’s economy rapidly grows, the energy sector faces two major challenges: an imbalance of supply and demand and a lack of distribution and transmission infrastructure.
As by far the largest wind power market in the world (with 63 GW installed capacity), China gets more than 30% of its wind market’s revenue from federal subsidies—an exceptional amount of support from the government that has adversely caused a massive oversupply issue. In 2011, abandoned wind power amounted to over 10 billion KWh, exceeding 50 percent of the industry’s profit. Much of that energy was wasted, mostly positioned near farms lacking sufficient distribution/transmission infrastructure capable of moving excess energy to areas of higher demand. ”

The leading clean energy magazine “Distributed Energy” has recently published an article about the cutting-edge technology Angstrom Advanced has developed to specially serve the Distributed Renewable Energy market: “Hydrogen is a very valuable alternative to fossil fuel for distributed energy generation, delivering a high-powered solution with minimal environmental and safety concerns. Green businesses, telecomm providers, governments, and renewable energy advocates can now produce on-demand energy for their assets, at minimal cost and using commercially available equipment. This article will look at the benefits associated with hydrogen and fuel cell energy systems compared to fossil fuel and chemical alternatives as well as the inherent costs associated with a fuel cell on-demand generator. This analysis will show that it is not only technically feasible to use hydrogen for on-demand energy in certain, but also that it can be more economic than the alternatives. Diesel generators are valuable when used only for applications that have short run times (less than eight hours per day) and where they are in proximity to a low-cost fuel source. For longer run times, and when used in more remote and extreme conditions, renewable hydrogen generators are an ideal solution for providing on-demand energy…

| In this setup, compressed air is pumped through a compressor filter, along with polymer membrane filters. Due to variable solubility and proliferation factors, different gasses in the air penetrate the membrane at different rates, allowing for their separation. Based on their diffusion rates, the gasses in the air are then placed into one of two categories: “rapid gas” or “slow gas.” After being compacted and purified (to remove oil, water, and dust), the air will be passed through the membrane in order to create a separation of the gasses. The “rapid gasses,” oxygen, carbon dioxide, and some vapors, will be the first to infiltrate the membrane wall, and exit through a discharge port via air pressure. Because nitrogen is characterized as a “slow gas,” it will flow from the gas collector at the end of the pressure box, and finally enter a buffer tank where it will be stored. |

Hydrogen on the Rise: A renewable energy based storage solution
A new application of hydrogen is being deployed that’s helping solve humanity’s ever-evolving energy woes. Traditionally, hydrogen has a large number of applications, used in everything from industrial products to food packaging. It’s also a primary component in ammonia. Ammonia used in fertilizer and industrial processes amounted to 160 million-tons worldwide in 2011 alone.
Not surprisingly, the market demand for new, less expensive sources of hydrogen is driven heavily by fertilizer and manufacturing processes. However, a new market demand is emerging for hydrogen in another sector: energy. Power plants in Germany and in Canada (using wind and natural gas, respectively) are today supplementing their primary electrical generators with advanced configurations of hydrogen technologies. These retrofits help plants save money by smoothing supply, and converting excess electricity generated into storable hydrogen gas, which can be returned to electricity using a turbine generator or a fuel cell.
For natural gas-fired plants, there are enormous expenses associated with starting the generators from scratch—from the amount of fuel it takes to the time it takes to gain momentum. To mitigate this concern, operators often continuously run their turbines, regardless of electricity demands. Fuel and energy are, therefore, wasted, as the additional electricity generated is more than the plant will be paid for or is expected to supply.
Wind farms face a similar supply-demand problem. Although wind is free (unlike natural gas), it’s often generated at times when there isn’t a demand for the electricity (off-peak hours). As a result, there tends to be an abundant supply of low-cost, renewable energy that goes unused, and never paid for.
The hydrogen solution
To cut costs and expand margins, the hydrogen power plant strategy is simple: store extra electricity supply as high-energy hydrogen gas, and deliver it later as electricity, when it’s not only in demand but also revenue-generating.
In the last two years, there’s been a lot of public and private attention directed at hydrogen technologies, especially in distributed generation and renewable hydrogen energy. To be clear, hydrogen is an energy carrier, not a source, as it doesn’t actually make energy. It needs the reaction with a catalyst and oxygen to release its contained energy, which often occurs in a fuel cell. Hydrogen is not naturally occurring anywhere on earth, such as oil or coal or even sunlight. Rather, hydrogen must be obtained from processes like electrolysis (running direct current through water to make H2), or reforming natural gas (which contains hydrogen). As this first method demands energy usually derived from fossil fuel, and the latter is derived directly from a fossil fuel, it’s seems reasonable to question hydrogen as a clean energy solution.
Hydrogen produces only pure water when used for energy, so if it takes carbon-intensive fuels to make the hydrogen, then why explore it as a source of clean energy? Fortunately, there are many sources of energy in the world that don’t contain fossil fuels. Indeed, hydrogen can—and has been—created through electrolysis powered by clean energy, and more projects combining renewable energy and hydrogen are being developed right now.
Hydrogen & wind
In no industry are the benefits of supplemental hydrogen systems more apparent than for wind energy. Diminishing tax credits and subsidies have encouraged developers, operators, and owners to explore new ways to increase margins on current and developing wind projects. Additionally, in the wind industry, everyone knows and fears the concept of “curtailment”—the forced shutdown of renewable energy infrastructure by utilities or other PPA recipients. Curtailment occurs when the grid is overloaded by electrical supply, and utilities have contracts with suppliers other than renewable wind and solar. When curtailment occurs, wind turbines and solar panels lay idle. During curtailment, renewable energy operators’ assets sit and depreciate, generating little or no revenue. In certain regions, like Texas and Oklahoma, curtailment occurs as often as 50% of generating time.
A hydrogen-based energy storage system provides operators of wind-generation assets a solution to the issues of curtailment and diminished returns from generating during off-peak hours. Storing less valuable energy generated in curtailment or off-peak periods, wind farm operators can return the energy to the grid in higher value, on-peak times, using a hydrogen fuel cell. The differences in tariff prices written into wind farm PPAs is often considerable enough to consider storage, and many inherent characteristics of fuel cell technology make it a front-runner for future energy storage projects.
Hydrogen & energy storage
In a commercial sense, the hydrogen debate has been gridlocked for years, without much attention in political and business agendas because of the perceived high costs of the technology. Today, new technologies and unique business models present a strong case for implementing hydrogen-based energy storage—especially when paired with intermittent renewable energy sources. Compared to alternate energy storage methods, hydrogen has real advantages that all consummate cost reduction and margin expansion.
For one, the cost of electrolyzers (what makes hydrogen from electricity) has decreased 25% in the last 10 years, and new innovations in fuel cell technology have made the systems more efficient. Consider that the average US coal-fired power plants are 40% efficient. And, the round-trip efficiency of hydrogen storage systems (“round-trip” referring to the energy loop of electricity-to-hydrogen-to-electricity again) has now reached 45% efficiency. Electrolysis techniques have reduced the need for additional transformers, so systems can adapt to the current and voltage of wind turbines and transmission facilities. This reduces capital cost for additional transformers and increases system efficiency due to the system losses associated with transformer technology.
Secondly, fuel cells are a much more suitable storage technology for grid applications because they provide a constant level of energy, as opposed to alternative methods such as batteries or compressed air, which decrease in output over time.
Niche markets appear to be fully embracing the potential of hydrogen. Germany already has hydrogen-power plants, and a new transportation project that’s building 50 new refueling stations to supply hydrogen-powered vehicles. In the US, hydrogen buses are in operation in Austin, Birmingham, Cleveland, and several other cities. There’s also a large bus fleet in Reykjavik, Iceland where there’s a vast supply of renewable energy to cheaply create hydrogen fuel. OEM are already predicting an energy market transformation with a planned rollout of hydrogen, fuel cell vehicles starting in 2014 from Mercedes Benz, BMW, Toyota, General Motors, Nissan, Honda, and Ford. Hydrogen energy, it seems, is no longer an idyllic power solution but, rather, a market-based clean energy solution.

Main Principle of a Hydrogen Generator by Methanol
The mixed gas after reaction is passed though the heat exchanger to have the heat exchanged with feed gas in order to recover part of heat and then fed further into the gas-liquid separation buffer to separate the unreacted methanol and water, prior to passing to the condenser and cooling gas dryer for condensation in order to ensure the methanol in the reforming gas to meet the specified quality. The liquid from condensation and separation is the mixture of methanol and water, which are returned back to the feedstock tank for reuse. The reformed gas enters a set of PSA system, which separates all impurities through the adsorption and separation in one time. The hydrogen purification through Angstrom Advanced PSA is adopted in the manner of 4-1-2/P and desorption at the atmospheric pressure (4 absorbers, one absorber is in adsorption, 2 times of pressure equalization). Each adsorber in a cycle undergoes adsorption (A); equalized pressure-drop for the first time (E1D); equalized pressure-drop for the second time (E2D); cis-exhale (PP), inverse purge (D); flushing (P); equalized pressure increase for the second time (E2R); equalized pressure increase for the first time (E1R) and the final pressurisation (FR). The four adsorbers shift regularly, alternating between adsorption and regeneration, according to the arranged program in a closed loop. In this way raw gas feeds and hydrogen withdraws continuously. There are a small amount of carbon monoxide and about 35%(v/v) hydrogen in the desorbed off gas. If it is recovered and used as fuel, it brings the benefit of saving energy and minimizing the pollution. With the best rates and a highly trained staff, we guarantee to meet your needs and work with you to obtain your project goals.

Nitrogen Generating Plant (Angstrom Advanced Knowledge base)
The technology of air-to-nitrogen production with the use of adsorption processes in nitrogen generators is well studied and widely applied at industrial facilities for the recovery of high-purity nitrogen. The operating principle of a nitrogen generator utilizing the adsorption technology is based on the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, Pressure swing adsorption (PSA) plants have found the broadest application world-wide. The system’s design is based on the regulation of gas adsorption and adsorbent regeneration by means of changing pressures in two adsorber–adsorbent-containing vessels. This process requires constant temperature, close to ambient. With this process, nitrogen is produced by the plant at the above-atmospheric pressure, while the adsorbent regeneration is accomplished at below-atmospheric pressure. The swing adsorption process in each of the two adsorbers consists of two stages running for a few minutes. At the adsorption stage the adsorbent serves to adsorb predominantly one of the gas mixture components with the recovery of product nitrogen. At the regeneration stage the adsorbed component is released from the adsorbent and is vented in the atmosphere.
