In Europe, floods are linked to high fluctuations of atmospheric pressure. These variations are also known as the North Atlantic Oscillation. Stefan Zanardo and his colleagues at Risk Management Solutions, London, UK, analyzed historical records of severe floodings in Europe since 1870. They compared patterns of atmospheric pressure at the time of the floods. When the North Atlantic Oscillation is in a positive state, a depression over Iceland drives wind and storm throughout northern Europe. In a negative state, however, it makes southern Europe moister than usual. Normally, floods occur in northern Europe. They cause the most damage if the North Atlantic Oscillation was positive in winter. If enough rain has already fallen to saturate the soil, high risk conditions for flooding are met. Air pressure in Europe may change with global warming and public administrations should take this into account when assessing flood risk in a region, the researchers say.
This is important because flooding in Europe often causes loss of life, significant property damage , and business interruptions. Global warming will further worsen this situation. Risk distribution will change as well. The frequent occurrence of catastrophic flooding in recent years has sparked strong interest in this problem in both the public and private sectors. The public sector has been working to improve early warning systems. In fact, these early warning systems have economic benefits. In addition, various risk mitigating strategies have been implemented in European countries. These include flood protection, measures to increase risk awareness, and risk transfer through better dissemination of flood insurance. The fight against the root cause, global warming that is, however, is still far behind to what is needed.
Correlations between large-scale climate patterns, and in particular the North Atlantic Oscillation, and extreme events in the water cycle on the European continent have long been described in the literature. With with more severe and more often flooding as well as alarming global warming scenarios, raising concerns over future flood-related economic losses have become the focus of public attention. Although it is known that climatic patterns also control meteorological events, it is not always clear whether this link will affect the frequency and severeness fo flooding and the associated economic losses. In their study, the researchers relate the North Atlantic Oscillation to economic flood losses.
The researchers used recent data from flood databases as well as disaster models to establish this relation. The models allowed the quantification of the economic losses that ultimately caused by the North Atlantic Oscillation. These losses vary widely between the countries within the influence of the North Atlantic Oscillation. The study shows that the North Atlantic Oscillation can well predict the average losses in the long term. Based on the predictability of the North Atlantic Oscillation, the researchers argue that, in particular, the temporal variations of the flood risks caused by climate oscillations can be forecast. This can help to take encounter catastrophic flood events early on. As a result, flood damage can be minimized or even avoided. As scientists improve their predictions for the North Atlantic Oscillation, society will be better prepared for future flooding.
At Frontis Energy we have spent much thought on how to recycle CO2. While high value products such as polymers for medical applications are more profitable, customer demand for such products is too low to recycle CO2 in volumes required to decarbonize our atmosphere to pre-industrial levels. Biofuel, for example from field crops or algae has long been thought to be the solution. Unfortunately, they require too much arable land. On top of their land use, biochemical pathways are too complex to understand by the human brain. Therefore, we propose a different way to quickly reach the target of decarbonizing our planet. The procedure begins with a desired target fuel and suggests a microbial consortium to produce this fuel. In a second step, the consortium will be examined in a bio-electrical system (BES).
Today’s atmospheric CO2 imbalance is a consequence of fossil carbon combustion. This reality requires quick and pragmatic solutions if further CO2 accumulation is to be prevented. Direct air capture of CO2 is moving closer to economic feasibility, avoiding the use of arable land to grow fuel crops. Producing combustible fuel from CO2 is the most promising intermediate solution because such fuel integrates seamlessly into existing urban infrastructure. Biofuels have been explored intensively in recent years, in particular within the emerging field of synthetic biology. However tempting the application of genetically modified organisms (GMOs) appears, non-GMO technology is easier and faster to implement as the required microbial strains already exist. Avoiding GMOs, CO2 can be used in BES to produce C1 fuels like methane and precursors like formic acid or syngas, as well as C1+ compounds like acetate, 2-oxybutyrate, butyrate, ethanol, and butanol. At the same time, BES integrate well into urban infrastructure without the need for arable land. However, except for methane, none of these fuels are readily combustible in their pure form. While electromethane is a commercially available alternative to fossil natural gas, its volumetric energy density of 40-80 MJ/m3 is lower than that of gasoline with 35-45 GJ/m3. This, the necessary technical modifications, and the psychological barrier of tanking a gaseous fuel make methane hard to sell to automobilists. To produce liquid fuel, carbon chains need to be elongated with alcohols or better, hydrocarbons as final products. To this end, syngas (CO + H2) is theoretically a viable option in the Fischer-Tropsch process. In reality, syngas precursors are either fossil fuels (e.g. coal, natural gas, methanol) or biomass. While the former is obviously not CO2-neutral, the latter competes for arable land. The direct conversion of CO2 and electrolytic H2 to C1+ fuels, in turn, is catalyzed out by electroactive microbes in the dark (see title figure), avoiding food crop competition for sun-lit land. Unfortunately, little research has been undertaken beyond proof of concept of few electroactive strains. In stark contrast, a plethora of metabolicstudies in non-BES is available. These studies often propose the use of GMOs or complex organic substrates as precursors. We propose to systematically identify metabolic strategies for liquid bio-electrically engineered fuel (BEEF) production. The fastest approach should start by screening metabolic databases using established methods of metabolic modeling, followed by high throughput hypothesis testing in BES. Since H2 is the intermediate in bio-electrosynthesis, the most efficient strategy is to focus on CO2 and H2 as direct precursors with as few intermediate steps as possible. Scalability and energy efficiency, economic feasibility that is, are pivotal elements.
Yeasts are among the microorganisms with the greatest potential for liquid biofuel production. Baker’s yeast, (Saccharomyces cerevisiae) is the most prominent example. While known for ethanol fermentation, yeasts also produce fusel oils such as butane, phenyl, and amyl derivate aldehydes and alcohols. Unlike ethanol, which is formed via sugar fermentation, fusel oil is synthesized in branched-off amino acid pathways followed by aldehyde reduction. Many enzymes involved in the reduction of aldehydes have been identified, with alcohol dehydrogenases being the most commonly observed. The corresponding reduction reactions require reduced NADH but it is not known whether H2 produced on cathodes of BES can be involved.
Clostridia, for example Clostridium acetobutylicum and C. carboxidivorans, can produce alcohols like butanol, isopropanol, hexanol, and ketones like acetone from complex substrates (starch, whey, cellulose, etc. ) or from syngas. Clostridialmetabolism has been clarified some time ago and is different from yeast. It does not necessarily require complex precursors for NAD+ reduction and it was shown that H2, CO, and cathodes can donate electrons for alcohol production. CO2 and H2 were used in a GMO clostridium to produce high titers of isobutanol. Typical representatives for acetate production from CO2 and H2 are C. ljungdahlii, C. aceticum, and Butyribacterium methylotrophicum. Sporomusa sphaeroides produces acetate in BES. Clostridia also dominated mixed culture BESs converting CO2 to butyrate. They are therefore prime targets for low cost biofuel production. Alcohols in clostridia are produced from acetyl-CoA. This reaction is reversible, allowing acetate to serve as substrate for biofuel production with extracellular energy supply. Then, energy conservation, ATP synthesis that is, can be achieved from ethanol electron bifurcation or H2 oxidation via respiration. While possible in anaerobic clostridia, it is hitherto unknown whether electron bifurcation or respiration are linked to alcohols or ketone synthesis.
Phototrophs like Botryococcus produce C1+ biofuels as well. They synthesize a number of different hydrocarbons including high value alkanes and alkenes as well as terpenes. However, high titers were achieved by only means of genetic engineering, which is economically not feasible in many countries due to regulatory constrains. Moreover, aldehyde dehydration/deformylation to alkanes or alkenes requires molecular oxygen to be present. Also the olefin pathway of Synechococcus depends on molecular oxygen with the cytochrome P450 involved in fatty acid decarboxylation. The presence of molecular oxygen affects BES performance due to immediate product degradation and unwanted cathodic oxygen reduction. In contrast, our own preliminary experiments (see title photo) and a corrosion experiment show that algae can live in the dark using electrons from a cathode. While the enzymes involved in the production of some algal biofuels are known (such as olefin and aldehyde deformylation), it is not known whether these pathways are connected to H2 utilization (perhaps via ferredoxins). Such a connection would be a promising indicator for the possibility of growing hydrocarbon producing cyanobacteria on cathodes of BES and should be examined in future research.
At Frontis Energy we believe that a number of other microorganisms show potential for BEEF production and these deserve further investigation. To avoid GMOs, BES compatible co-cultures must be identified via in silico metabolic reconstruction from existing databases. Possible inter-species intermediates are unknown but are prerequisite for successful BES operation. Finally, a techno-economical assessment of BEEF production, with and without carbon taxes, and compared with chemical methods, will direct future research.
In Germany, we seem to remember White Christmas from fairy tales only. Now there is also scientific evidence that winter snow cover in Europe is thinning. Thanks to global warming, the snow cover decrease accelerated
The research group behind Dr. Fontrodona Bach of the Royal Netherlands Meteorological Institute in De Bilt analyzed snow cover and climate data from six decades from thousands of weather stations across Europe. The researchers found that the mean snow depth, with the exception of some local extremely cold spots, has been decreasing since 1951 at 12% per decade. The researchers recently published their research results in the journal Geophysical Research Letters. The amount of “extreme” snow cover affecting local infrastructure has declined more slowly.
The observed decline, which accelerated after the 80s, is the result of a combination of rising temperatures and the impact of climate change on precipitation. The decreasing snow cover can reduce the availability of fresh water during the spring melt, the authors noted.
The ancient, arid landscapes of Australia are not only fertile soil for huge forests and arable land. The sun shines more than in any other country. Strong winds hit the south and west coast. All in all, Australia has a renewable energy capacity of 25 terawatts, one of the highest in the world and about four times higher than the world’s installed power generation capacity. The low population density allows only little energy storage and electricity export is difficult due to the isolated location.
The volumetric energy density of ammonia is almost twice as high than that of liquid hydrogen. At the same time ammonia can be transported and stored easier and faster. Researchers around the world are pursuing the same vision of an “ammonia economy.” In Australia, which has long been exporting coal and natural gas, this is particularly important. This year, Australia’s Renewable Energy Agency is providing 20 million Australian dollars in funding.
Last year, an international consortium announced plans to build a $10 billion combined wind and solar plant. Although most of the 9 terawatts in the project would go through a submarine cable, part of this energy could be used to produce ammonia for long-haul transport. The process could replace the Haber-Bosch process.
Such an ammonia factories are cities of pipes and tanks and are usually situated where natural gas is available. In the Western Australian Pilbara Desert, where ferruginous rocks and the ocean meet, there is such an ammonia city. It is one of the largest and most modern ammonia plants in the world. But at the core, it’s still the same steel reactors that work after the 100 years-old ammonia recipe.
By 1909, nitrogen-fixing bacteria produced most of the ammonia on Earth. In the same year, the German scientist Fritz Haber discovered a reaction that could split the strong chemical bond of the nitrogen, (N2) with the aid of iron catalysts (magnetite) and subsequently bond the atoms with hydrogen to form ammonia. In the large, narrow steel reactors, the reaction produces 250 times the atmospheric pressure. The process was first industrialized by the German chemist Carl Bosch at BASF. It has become more efficient over time. About 60% of the introduced energy is stored in the ammonia bonds. Today, a single plant produces and delivers up to 1 million tons of ammonia per year.
Most of it is used as fertilizer. Plants use nitrogen, which is used to build up proteins and DNA, and ammonia delivers it in a bioavailable form. It is estimated that at least half of the nitrogen in the human body is synthetic ammonia.
Haber-Bosch led to a green revolution, but the process is anything but green. It requires hydrogen gas (H2), which is obtained from pressurized, heated steam from natural gas or coal. Carbon dioxide (CO2) remains behind and accounts for about half of the emissions. The second source material, N2, is recovered from the air. But the pressure needed to fuse hydrogen and nitrogen in the reactors is energy intensive, which in turn means more CO2. The emissions add up: global ammonia production consumes about 2% of energy and produces 1% of our CO2 emissions.
Our microbial electrolysis reactors convert the ammonia directly into methane gas − without the detour via hydrogen. The patent pending process is particularly suitable for removing ammonia from wastewater. Microbes living in wastewater directly oxidize the ammonia dissolved in ammonia and feed the released electrons into an electric circuit. The electricity can be collected directly, but it is more economical to produce methane gas from CO2. Using our technology, part of the CO2 is returned to the carbon cycle and contaminated wastewater is purified:
Global warming is – as the name already suggests – a global concern. It causes problems such as sea level rise, more frequent and more severe strms, and longer droughts. Thus, it global warming concerns all of us. To best fight global warming, adopting green energy in your life is the best viable solution.
Green energy is getting more attention today. It helps to reduce our carbon footprint and thus curbing the global warming. Increasing carbon footprint is the main cause for rising temperatures. Moreover, investing in green energy is also a business case generating steady revenue stream without marginal costs. Hence, many governments promote the use of green energy by providing subsidies and teaching people its benefits in their life.
There are many ways green energy is produced, for example, solar energy, wind energy, the energy produced through bio-waste. Fuel cells are a major breakthrough in this regard. They have impacted the production green energy in many ways. They are also convenient to use. As their fuel (hydrogen, methane …) is produced by using electrical energy, they can use a wide range of green sources to produce energy.
What Are Fuel Cells?
A fuel cells is a device that converts chemical energy into electrical energy. The process combines hydrogen and oxygen to produce water& electricity as main products. Fuel cells are somewhat similar batteries. The main difference is that a fuel is supplied without a charge-discharge cycle. Like batteries, fuel cells are portable and can be used with a variety of fuels like ethanol, methanol, methane, and more.
There are different types of fuel cells. But the most popular ones are hydrogen fuel cells that provide a wide range with only some of advantages as follows:
The cells are more efficient than conventional methods used to produce energy.
They are quiet – unlike, for example combustion engines or turbines
Fuel cells eliminate pollution by using hydrogen instead of burning of fossil fuels.
Fuel cells have a longer lifespan than batteries because fresh fuel is supplied constantly
They use chemical fuels that can be recycled or produced using renewable energy which makes them environmentally friendly.
Hydrogen fuel cells are grid-independent and can be used anywhere.
How Do Fuel Cells Work?
A fuel cell produces power by transforming chemical energy into electrical energy in reduction-oxidation processes, much like batteries do. However, unlike batteries, they produce electricity from external supplies of fuel to the anode and oxidants to the cathode. Fuel cells are capable of producing energy as long as the fuel required to produce energy is supplied. Main components of fuel cells are electrolytes that allow for ion exchange. They aid the electro chemical reaction.
Hydrogen, ethanol, methanol, and methane are used as a source of energy. Methane, which is extracted from the subsurface, can be transformed into hydrogen rich stream. With an abundance of the hydrogen in nature, fuel cells seem to be the most viable technology that helps to produce green energy at large scale and at the most affordable cost.
Fuel cells are all set to become the most reliable source of green energy in the near future. They are fuel efficient, so businesses can make the best use of them. At Frontis Energy, we offer a unique selection that helps you build and improve your own fuel cells – be it for research and development or for production.
Fuel cells are the devices that convert chemical energy directly into electrical energy. The process combines hydrogen and oxygen produce water& electricity as main products. Fuel cells are similar to batteries in that they produce electricity but also different in that a fuel is supplied without a charge-discharge cycle. Like batteries, they are portable and developed by technological experts. The cells can be used with a variety of fuels like ethanol, methanol, methane, and more.
Here are the advantages of hydrogen fuel cells –
The cells are efficient when compared to the conventional forms of producing energy.
Hydrogen fuel cells operate silently.
Fuel cells eliminate pollution by switching from burning of fossil fuels to hydrogen.
Fuel cells last longer than batteries because they use chemical fuels to produce energy.
Hydrogen fuel cells are grid-independent and can be used anywhere.
Components of Fuel Cells. A fuel cell converts chemical energy into electrical energy, much like a battery. But unlike batteries, they produce electricity from external supplies of fuels to the anode and oxidants to the cathode. Fuel cells can operate virtually continuously as long as the necessary fuel is supplied. Electrolytes are the major components of the fuel cells and keep that allow ion exchange. Fuel cells also have electrodes that are catalysts of the electrical chemical reaction.
Fuel for Fuel Cells.Fuel cells can operate using a variety of fuels like hydrogen, ethanol, methanol, and methane. Fossil fuels like methane are extracted from underground and converted into a hydrogen rich stream. There is also a huge abundant amount of hydrogen in water which can be used for the hydrogen power supply .For higher voltages, fuel cells can be stacked. Fuel cells can power anything from microchips to buses, boats, and buildings.
Fuel Cell Efficiency. The fuel cells are much more efficient than conventional power generation. This is because conventional power is generated be converting chemical energy into heat, mechanical energy and lastly into electrical energy. Fuel cells are converting energy directly into electrical energy and are much more efficient.
Fuels cells are a promising technology and already a source of electricity for buildings and vehicles. The devices operate best with pure hydrogen. In contrast, fossil fuel reserves are in limited and the energy future of the world needs to include several renewable alternatives to our declining resources. Hydrogen is the most abundant element present in the universe and serves as the fuel for nuclear fusion in the sun. Due to this abundance, hydrogen fuel cells are the best green energy source.
Today’s companies are developing innovative techniques to use green energy such as fuel cells. There are different types of fuel cells under development, each with its own advantages, limitations, and potential applications. The classification is determined by the kind of electro chemical reactions taking place in the cell, the required kind of catalyst, the temperature range in which the cells operate, the required fuel, and other different factors.
Frontis Energy is an industry expert in fuel cells and electrolysis storage with more than 20 years of experience. We develop innovative environmental technology products and services. Our specialty is bio-fuels and wastewater with innovative solutions at competitive prices.
Fuel cells are clean, reliable, and portable
A fuel cell is a device that uses a source of fuel like hydrogen and an oxidant for creating electricity through electro chemical processes. It converts chemical energy into electrical energy like batteries found under the hoods of automobiles or in flashlights. The basic build-up is very simple. There are in principle two types of configurations which refer to the electrolyte and the two electrodes.
Many combinations of fuels and oxidants are possible in fuel cells. The fuel can be hydrogen, diesel, methanol, natural, etc., and the oxidants can be air, chlorine, or chlorine dioxide, and so forth. But most of today’s fuel cells are using hydrogen. The hydrogen used in fuel cells can be produced by a variety of fuels, including natural gas. A fuel cell splits hydrogen into electrons and protons. Fuel cells have several advantages over other common forms of power. They are cleaner, more efficient, and quiet.
There is no doubt that fuel cells are among the most efficient ways of green energy today. They are a decentralized and Eco-friendly alternative to conventional energy production. As the cost of centralized power rises, the cost of decentralized power continues to fall. Some power professionals believe the days of centralized power are numbered. Today, fuel cells are the best device to convert chemical energy into electrical energy.
Currently, we are using coal, oil, and gas as our energy resource. They are known as fossil fuels and when burned, they release heat energy that can be turned into electricity. Unfortunately, they cannot be replenished. This form of energy can also be harmful for the health and also a degrading factor for the entire health of the world. People today are turning towards the use of renewable energy for it is an energy source that is less harmful for the environment and for our health.
There are different renewable sources of energy in use today like solar, wind, and hydroelectric power. Wind turbines and solar panels are becoming an increasingly common sight to be used as energy resource. Some of the other forms of clean energies are geothermal, and energy from biomass. These are effective solutions for avoiding, minimizing, and mitigating the use of fossil fuels.
Here are the best benefits of a renewable energy source –
It ensures less global warming
Different human activities are overloading the atmosphere with various harmful gases and other emissions. These gases act like a blanket that result in a web of significant harmful impacts. Increasing the supply of renewable energy would allows the replacement of carbon intensive energy sources with to reduce green house gas emissions.
It improves the public health
Air pollution from using coal and oil is linked with breathing problems, heart attacks, cancer and neurological damage. Most of the negative impacts come from the air and water pollution. Wind, solar, and hydroelectric systems will generate electricity with no associated air pollution emissions.
It is better to use the inexhaustible energy
Strong winds, sunny skies, heat from underground water, and abundant plant matter will provide constant supply of energy. Renewable energy provides a significant share of electric needs, even after accounting for potential constraints.
There are many of economic benefits
Renewable energy is supporting thousands of jobs. Solar panels need workers to install them; wind farms need technicians for maintenance.
There are a lot of reasons for moving towards the use of renewable energy for now and in the future. But there are some limitations also with the use of such energy resources. It is thus advisable to contact the support experts of professionals dealing with the use of green house gases for energy production.
Together with water, energy is the most valuable resource we have. It powers different industries. Energy provides a system with the ability to perform work and without it, industries cannot function. Using green energy for manufacturing in growing economies is not only more sustainable but can also save money. Green energy is the energy that can be harnessed without harming the environment. This source of energy is environmentally friendly releasing very little toxic compounds into our atmosphere.
Green energy is defined as renewable energy since it is not exhausted at the source. It is also referred to as a clean energy due to the lack of negative impacts on the environment. To keep the planet clean it is important to use such alternative energy sources. One prominent example is the energy obtained from the processing of waste materials to make the environment cleaner. These materials normally pollute the environment by increasing the amount of waste material and toxic substances on the Earth’s surface.
Why use renewable energy?
It is critical to use renewable energy for reducing the global carbon emissions. Investments into such green energy have increased gradually as the cost of technologies fall and efficiency continues to rise. These are the reasons why renewable are rapidly making their way up the agenda –
Growing Price Competitiveness
Non-renewable sources of energies like fossil gas, oil, or coal, threaten power plant operators & end users, because of the insecurity of marginal costs. The price of gas fluctuates across regions, in a cyclical, though unpredictable fashion.
Renewable energy prices, on the contrary, have been continually decreasing. There have been significant price drops in solar over the last decade and the prices for onshore wind also drop significantly.
Renewable have been heavily encouraged by policy makers and direct as well as indirect subsidies. This has driven down the costs during early deployment. The wind or solar farms are usually constructed for up to 25 to 30 years of operation, and even longer for hydro power plants. Thus, renewable continues to generate electricity for a very long time while their efficiency continues to increase.
The majority of non-renewable sources are concentrated in certain regions, whereas renewable energy can be domestic. This helps nations to reduce their dependencies on imported sources. The energy independence thus plays a significant role in addressing our energy needs by replacing foreign energy imports with clean electricity.
It is important to manage diminishing fossil fuel reserves and climate change is the biggest challenge the world is facing today. People are moving from non-renewable energy use to green energy to save the world for the future but also to save money. Clean energy development is vital to combat global warming and to limit its most devastating effects.
Fuel cell technology is one of the best alternatives to fossil fuel combustion because it reduces air pollution affecting the health of millions. Fuel cells use hydrogen and oxygen from air to produce electricity with water being the final product. While the fuel, hydrogen, can be obtained from water, engineers use natural gas to produce most of today’s hydrogen. Nonetheless, a global hydrogen initiative of scientists and engineers has plans to look into renewable and environmental-friendly ways of producing hydrogen in the future.
Fuel cells have various advantages compared to conventional power sources like the internal combustion engines or batteries.
These are the benefits of fuel cells –
Fuel cells have higher efficiency than diesel or gas engines.
Fuel cells work silently and they are ideally suited for use within buildings like commercial constructions.
Fuel cells such as hydrogen fuel cells eliminate pollution caused by burning fossil fuels.
Fuel cell also eliminates greenhouse gases for example, when clean electrolysis of water is used.
Fuel cells do not require conventional fuels like oil or gas (though they can use them) and thus reduce the economic dependence on oil-producing countries.
Fuel cells generate electricity that can be distributed and be grid-dependent.
Stationary fuel cells can be used to generate power at the point of use for small and medium decentralized power grids.
High temperature fuel cells produce process heat that is suited to co-generation applications.
Unlike in batteries, the operation time of fuel cells can be extended by increasing the amount of fuel.
Like a battery, a fuel cell has two electrodes which carry charges from one electrode to the other. The reaction in a single fuel cell produces only about 0.7 volts. However, if the cells are stacked and connected in in series, their voltage increases and they can be used in cars. Scientists and engineers are developing fuel cells that run on wastewater. These so-called microbial fuel cells use microbes to break down organic matter in the wastewater. This fuel cell technology is still requires cost optimization and performance improvements to become fully competitive.
