Air Source Heat Pumps and Water Source Heat Pumps – What Are They and How To Choose One?

/

[et_pb_section admin_label=\”section\”] [et_pb_row admin_label=\”row\”] [et_pb_column type=\”4_4\”][et_pb_text admin_label=\”Text\”] What are Air-Source Heat Pumps (ASHPs) and Water-Source Heat Pumps (WSHPs)? Air-Source Heat Pumps (ASHPs) and Water-Source Heat Pumps (WSHPs)follow the same thermodynamic cycle called the ‘Vapour Compression Cycle’. (Please watch our ‘Heat Pump Knowledge Series’ to learn more about the thermodynamic cycle). How To Choose Between Air-Source and Water-Source Heat Pumps? The air source heat pump takes the input of electricity, extracts the heat from the ambient air, and gives hot water up to 90 degrees Celsius. Due to the extraction of heat from the ambient air, the ambient gets cooler. So, if there is a requirement for both hot water and cold air, then the air source heat pump is the solution. Water source heat pump takes the input of electricity, extracts heat from ambient water or process return water from industrial processes, and gives hot water up to 90 degrees Celsius. Due to the extraction of heat from the water, the water gets cooled in the range 7 to 30 degrees Celsius and this temperature is dependent on the temperature required for hot water. If there is a  requirement for both hot water and cold water, then the water source heat pump is the solution. (Click here to find out how the cost of heat pumps compare with the cost of other heating sources) Get Both Heating and Cooling Hot water is generally used in industries for degreasing, for pre-treatment, or for washing machines. In the commercial sector,  it can be used for bathing purposes or in kitchens. Coldwater can be used to reduce the load on chillers and cold air can be used for space cooling where the room temperature has to be brought down. Check out Aspiration Energy\’s heat pump solutions. Environmental and Financial Payback As both the heat pump types run on the same principle, both run with almost the same efficiency. Both the heat pumps are useful to reduce the CO2 emissions and help industries to reduce their energy bills. Return on investment is high if the existing system is an electric heater or a hot water generator. If you replace them with the heat pump, then the payback period will be less than 1.5 years.

How Much Is ‘Not Replacing The Diesel Boiler In Your Hotel’ Costing You Every Day? This Case of a 4-Star Hotel Has The Answer!

/

[et_pb_section admin_label=\”section\”] [et_pb_row admin_label=\”row\”] [et_pb_column type=\”4_4\”][et_pb_text admin_label=\”Text\”] A heat pump is considered as a passive solar thermal system that can save up to half of what you usually spend for the diesel boiler. Let us consider this very simple example. A 4-star hotel was using a diesel boiler that consumed 40 liters of diesel, running  8 hours a day for the generation of hot water at 80 degrees centigrade. Now, let\’s see what difference it would make if we replace the diesel boiler with a heat pump. Calculating Boiler Capacity Installed First of all, we will calculate the heating capacity of a diesel boiler installed in the hotel using the formula where m is the fuel consumption rate. i.e., 40 liters for 8 hours a day CV is the calorific value of the diesel. i.e., 9500 kilocalories per liter n is the efficiency of diesel boiler i.e., 80%, calculating which gives the value of installed capacity of the boiler as 44 kilowatts. Calculating Heat Pump Capacity Needed The next step is the selection of heat pumps. If we use our standard model of 28-kilowatt heat pump, whose power input is 10 kilowatts, we should select two numbers to get the desired heating output of 44 kilowatts. In addition to this, we have to add the auxiliary load consumption by the circulation pumps which usually ranges from 1 to 1.5 kilowatts. So, the total power input could be 20 kilowatts + 1.5 kilowatts which is 21.5 kilowatts. Now let’s move to the savings part. Comparing Running Costs of Diesel Boiler With Heat Pump First of all, we will calculate the operating cost of the diesel boiler for one day. i.e., 40 liters of diesel used per day x cost of diesel per liter i.e., 70 rupees, which gives the value of 2800 rupees. Now calculating the operating cost of heat pump for one day i.e 21.5 kilowatts x  8 hours of operation x 8.5 rupees i.e, the unit cost of electricity, which gives a value of 1460 rupees. The difference between these two values, i.e, 1340 rupees, is our savings per day! Payback Period, Financial and Environmental Savings If you calculate the savings for one year by multiplying it with 360 days, their annual saving would be 4,82,400 rupees. Finally, if they start using heat pumps right now, the return of investment would be 1.5 to 2 years. By using a heat pump, they not only save the money but also reduce the emission of carbon dioxide to the atmosphere. Contact Us to Get Started Thank you.

Will Heat Pumps perform better for Automobile Engine Head Washing?

/

Are heat pumps more cost-effective and efficient than electrical heaters in a hot water application for the manufacturing industry? Case of an Automobile Manufacturer Let\’s talk about a customer – Automobile  Manufacturer. The application they used hot water for is Engine Head Washing and the capacity of operation is around 28 kilowatts. Their temperature requirement is 50 to 60 degrees Celsius and they were running two shifts of operation. Results of the intervention We visited them to understand this application and gave an exact 28 kilowatts heat pump to meet that temperature requirement. You can see the installation photograph (below).   Before the installation of a heat pump, their average electrical consumption per hour was around 24 units. After the installation of the heat pump, it drastically reduced to 12 units per hour and they were able to save 86000 units per year. Not only that, but they were also able to reduce their carbon emissions. So, the heat pumps are not only cost-effective and efficient but also renewable and sustainable. How did heat pump make this achievement possible? How was that drastic reduction in the number of units even possible? The answer to this question lies in the ambient. Yes, the Ambient! A Heat Pump uses ambient temperature heat along with the heat generated with the usage of electricity. It converts that heat and transfers the heat energy from the ambient to the required heat output. So, the 2 kilowatt of ambient heat along with the 1 kilowatt of the electrical unit gives out around 3 to 4 units of heat energy output. So, this is the working principle and in summary, this heat pump is going to save around  5.5 lakh rupees for the customer, for that particular application. Can you achieve the same? If you are using electrical heaters for your hot water application, please feel free to call us on 96777 63170 for a demo of our heat pump. Looking forward to hearing from you. Thank you.

Calculating and Comparing Levelised Cost Of Heat (LCH) Or True Cost of Heat in Rs./kWhth Of Commonly Used Heating Sources

/

Do you know it could be more than 3 TIMES CHEAPER to produce the same amount of heat through Heat Pumps than through a Diesel Boiler or an Electric Heater? In this video – in order to make a fair comparison – Levelised Cost of Heat or True Cost of Heat in Rupees per kilowatt-hour thermal (Rs./kWhth) is obtained for a variety of commonly used heating sources. Are you using diesel or LPG for heating water up to 90 degrees C? Now, the government talks about electrification of heat which means replacing diesel or LPG with electricity. But when you are comparing the operating cost of diesel and LPG with electricity, is it even comparable? Let’s find out. kCal vs kWh How do we compare the operating costs of diesel or LPG driven hot water generator and electricity? First of all, we have to understand kCal vs kWh. Are they very different from each other? Both are units of energy. 860 kCal is nothing but 1 kWh from units of energy perspective. Now when you are converting kCal to kWh or kWh into kCal what comes into the picture is nothing but the efficiency. In the case of a generator or a power generator, the efficiency of a generator comes into the picture. That’s why people do not compare kCal and kWh that easily. But in a hot water generator, the kCal is converted into heat and in an electricity generator, the electricity consumed in kWh is consumed into water delivery in terms of kCal and that kCal can be easily converted into kWh just by taking kCal and dividing by 860. This is the first thing that we need to understand. Typical Boiler Efficiency What is boiler efficiency? What goes into the boiler in terms of kCal supplied, in terms of the fuel’s calorific content gets converted into heat by burning and then gets out as kCal output of the hot water, that is being converted from the cold stage to the hot stage. That’s basically what is happening in the boiler. Then, what is efficiency? Efficiency is in the terms of the losses that take place in the flue gases or any other heat losses that are in an enclosure etc. What is the usual efficiency of the boiler? Boiler manufacturers will say 95% or 90% and whatnot. But boiler efficiency usually is in 70% or 75% range. Particularly if you operate the boiler at the low capacity, the boiler efficiency is more in the 50 to 60% range. Then what is the true kCal delivered as hot water from the kCal input as the fuel? Let’s find out! Converting Calorific Values to Cost of Heat So, what are the calorific values of some of the fuels? Here is the table that shows you what are the different calorific values. Now if you take 1 liter of diesel and take the calorific value and divide by 860, that is the number of kWh contained in 1 liter of diesel. Now here is a table that shows what is per kg and per liter calorific value of many of the fuels. Table Comparing True Cost of Heat from Various Fuels Fuel​ Calorific Value​ Litre/kg​ Boiler Efficiency​ kW​ Litre/kg​ Fuel Price​ Cost of Energy Spent per kWh ​(Rs)​ ​ kCal​ kW​ ​ ​ ​ ​ ​ ​ Furnace oil​ 9454.84​ 11.00 ​ per liter​ 60%​ 6.6​ per liter​ 36​ 5.45 ​ Diesel (HSD)​ 9422.3​ 11.00 ​ per liter​ 60%​ 6.6​ per liter​ 63​ 9.55 ​ SKO​ 8833.3​ 10.30 ​ per liter​ 60%​ 6.18​ per liter​ 50​ 8.09 ​ LPG​ 11017.9​ 13.00 ​ per kg​ 60%​ 7.8​ per kg​ 43​ 5.51 ​ Propane​ 12033.7​ 14.00 ​ per kg​ 60%​ 8.4​ per kg​ 42​ 5.00 ​ Coal/Coke​ 5250​ 6.00 ​ per kg​ 60%​ 3.6​ per kg​ 8​ 2.22 ​ Briquettes (Sugarcane husk)​ 3996​ 4.65 ​ per kg​ 60%​ 2.79​ per kg​ 4.5​ 1.61 ​ Electricity​ 860​ 1​ per unit​ 95%​ 0.95​ per unit​ 8​ 8.42 ​ Heat Pump​ 860​ 3​ Per unit​ 300% *​ 3​ Per unit​ 8​ 2.67​ Now to find the true cost of the energy delivered, multiply the calorific values by the efficiency of the boiler. Let’s assume it as 70%, what happens to the cost? What is the cost per kWh so that you can compare it directly? Nothing else but the calorific value of the fuel multiplied by efficiency divided by 860 and multiplied by the cost of fuel will give you the true cost. So, if you take a diesel-based hot water generator, as you can see the table, that the calorific value of 9400 approximately kCal per liter, it delivers about 11 kWh per liter and if you take only the 60% efficiency, every liter will be able to deliver 6.6 kWh. If you take 66 rupees per liter of diesel – the current diesel price is slightly higher than this – you will find that per kWh price of running a diesel-based hot water generator is 10 rupees. Now is your electricity being as expensive as your 10 rupees per kWh, actually may not be. So, it doesn’t make sense for you to run a diesel-based hot water generator even if your electricity price is directly or anything less than 10 rupees per kWh. But look at the last row – heat pumps! How do Heat Pumps compare to others? Heat pumps absorb heat from the atmosphere and deliver more heat for every unit of electricity supplied. For every kWh of electricity supplied, heat pumps are able to deliver up to 3 kWh of heat energy. So, what it means is even if your kWh of electricity, the cost is 10 rupees – since it generates 3 units of energy – per kWh cost of running a heat pump for delivering hot water is less than 3 rupees. So, if you have a diesel boiler, diesel-based hot water generator, or any other fuel, I have made a table that compares all the fuels and their cost per kWh based on these numbers. If you know what your efficiency is, you can work out what is the kWh of delivered heat for your existing hot water generator. We will be happy to help you with this exercise and make a decision on choosing the right hot water source for your business. Please contact us.

Heat Pump Knowledge Series Part 2: Components of Heat Pump System

/

Ever wondered what\’s inside a heat pump system that makes it efficiently extract and transfer heat for your use? Watch this second video of our \’Heat Pump Knowledge Series\’ to find out what the four essential components of a heat pump are and their roles in heat pump operation. WELCOME TO EPISODE 2 Hello all, Welcome back to the ‘Heat Pump Knowledge Series’ presented to you by Aspiration Energy in collaboration with IIT Madras. In this episode, we will be looking into the heat pump system components and what it takes to build a great heat pump. THE FOUR KEY COMPONENTS OF HEAT PUMP For any good heat pump system, there are four key components that govern the design of the system. The first one is the Compressor which is the heart of the system and there are various choices for compressors which we will look into more detail. The second one is the Condenser from where the heat is removed and delivered to your process. So we will look into the various choices you have and how each one fits into the application that you have in your mind. The third one is, of course, the Expansion valve, which is one of the critical components in the refrigeration cycle and which allows how effective the system is. And the fourth one is your Evaporator. The choice of evaporator depends on what kind of heat pump design you have and the sources of heat. Of course, all of this is governed by a Controller. There are many choices for a controller which we will briefly look in to and see what their differences are. COMPRESSOR AND ITS TYPES When we move on to the Compressor, there are many choices. The first and foremost and the most common one that is used in the heat pump system is the Scroll Compressors. These are available for commercial AC systems which are now being developed for heat pump systems as well. In the range, it is available from 5 tonnes to about 40 tonnes of refrigeration and for heat pumps, single compressor systems are available up to 50 kW of heating and even up to temperatures of 95 degrees C. For this, the second type of compressors we have is Screw Compressors which are typically a large compressor which are available from a 200kW up to an MW in size and the temperatures of 60 degrees C and these systems become very expensive especially when you start looking at small applications. The third is the Reciprocating Compressors which are very commonly available in Refrigerators and are very small systems typically about 100s of Watts but reciprocating compressors are also available in open shaft design. The image that you see here is the Hermetic design which will be also available in open shaft design which can go up to 100s of kilowatts but nevertheless for the kind of application we are dealing with, reciprocating compressors are seldom used because of its complexity and the number of moving parts. And the last one is the Rotary Compressor which is now becoming popular in the refrigeration circles because of its capacity of up to 5 tonnes and its ability to handle temperatures up to 60 degrees C. In the heat pumps, it is not commonly found. Some of the common manufacturers of the system that you know are the Copelon Scroll from Emerson which makes the scroll compressor. They are world leaders in Scroll compressors and in the reciprocating compressors, one of the biggest manufacturers is the Danfoss company which provides from 100s of watts to a couple of kilowatts in size. In the Screw compressor, the screw is typically very complex machine and it is manufactured by very few companies in the world and one of them is Bitzer which has a manufacturing plant in China and it is a German-based company which manufactures the screw compressors and of course, Highly is basically a Hitachi company which manufactures these rotary compressors in Gujarat and this is one of the popular compressors for air conditioning which is currently being evaluated for heat pump applications too. So, we are going into more detail about the selection of compressors for applications, a little later in the video series, but for today, we will look into what the other components of the heat pump system are, to give you a general overview on what makes a good system. CONDENSERS AND ITS TYPES The next in series is the Condenser. Of course, there are various options for the condensers just like you have various options for compressors. The Popular one is called Shell Coil. Because it can be easily built and it is also typically tolerant to a lot of impurities in water. It is typically designed for temperatures less than 60 degrees C just like the Swimming Pool Heat Pumps and also where the direct water is used inside the heat pump system. The second and more popular option for the heat pump, primarily for the high-temperature application and also for handling a low approach temperature to give you the most effect out of the heat pump, is the Tube-in-Tube condenser where the twisted coil is inserted into another tube as shown in the figure here and because of the turbulence inflow you can achieve very very high efficiency in heat transfer. However, these systems are quite expensive and also are prone to clogging. So, they are typically recommended only when the impurities in the water can be controlled but nevertheless compared to the Shell coil – which is very compact – Tube-in-Tube can provide an equivalent amount of heat transfer. So, it is very efficient in terms of footprint. The third kind of heat exchanger which is very common in an industrial process is the Shell and Tube which is maintenance-friendly and it can tolerate all kinds of dirty fluids and it can handle large volumes so it can also act as a buffer tank rather than

Heat Pump Over LPG Boiler For Hot Water In Hotels – A Case Study of a 4 Star Hotel

/

As hotels across the country are struggling with low occupancy rates and trying hard to reduce their operational expenses, one smart hotel owner figured out a simple solution that saves 70% on their energy bill. Curious about what that solution is? Watch the short video below by our CEO answering just that!  TRANSCRIPT OF THE VIDEO Are Heat Pumps for Hot Water Bathing Applications Really Safer, More Economical and Environmentally Friendly For Hotels? We are talking about a 4-star hotel in Chennai where they were using LPG. They were consuming 35-50 kgs of LPG a day for hot water to cater to the bathing needs of the guests.  The increasing LPG cost was affecting their bottom line and what was more bothersome was the handling of LPG. The found it to be a safety hazard and found it more difficult to handle LPG. What is the solution? We gave a Heat Pump system – a more energy-efficient and safer product.  And we said we don’t need that much modification for the existing system; we integrated with the existing clarifier tank. It was also needing to handle variable heating needs from 40 degrees to 90 degrees Centigrade.  They also wanted a fool-proof system because it was critical to provide hot water at all times to the guests. So they wanted a monitoring mechanism to be an error-free mechanism.  We gave a 28kW Heat Pump system to them; We integrated it; We installed it on the rooftop that was extremely challenging.  We integrated with their existing hot water calorifier. We did it in three days. The integration was direct because the water quality was good. We didn’t need to install an extra heater, heat exchanger, extra circulation pump, or any of that. The cost was very low because of that.  With the 28kW heat pump system, we also gave a thermal energy monitoring system. What we actually did was to give it on the rental because they were not very sure that this heat pump will work for them, will it save for them, will it cater to all their needs, will it be reliable.  So, we gave the Heat Pump on rental to them. They looked at the savings; they monitored the savings using our heat monitoring system. We gave them our monitoring system as well. By looking at the savings they were so happy that they were willing to buy the system and convert the Rental into a CapEx.   The energy system replaced 35 to 50 kgs of LPG per day that cost about Rs.2500 every day for them and replaced it with electricity. Since the COP of the heat pump system was about 3, it consumed 1 unit of electricity to produce 3 units of heat and hence they spend only 900 Rs. a day and get their heating requirement for all their bathing water applications satisfied with only 900 Rs. a day.  Their payback period was less than 16 months.. less than 1 and a half years. This is how the installation looked on their rooftop.  Technically, this was a safer system..easier to operate..easy to monitor and control.  Financially, it saves 70% of their energy costs. They had a payback period of less than 16 months. Environmentally, although they were using a cleaner fuel like LPG, because the consumption was reduced one-third, because the heat pump was absorbing heat from the atmosphere and giving out as heat, the savings on CO2 in terms of environmental damage avoided was also about 11000 kgs over the period of last few months that we have operated the heat pump system. So, not only was it economical this was also ecological. So, overall this heat pump is going to save Rs.6.5 lakhs per annum for the customer.  If you are using any other thing other than a heat pump for heating, for bathing application or washing application in your hotel, we will be happy to suggest a heat pump system which can be safer, more economical, ecological…If you have any questions about whether it will work or not, you can always rent a system..you can try it out for a few months – see if it works for you and then convert into CapEx.  BUY IT AFTER YOU TRY IT!!! We look forward to hearing from you…Thank you.

Direct or Indirect process heat integration?

/

[et_pb_section fb_built=\”1\” _builder_version=\”3.22\” collapsed=\”off\”][et_pb_row _builder_version=\”4.6.5\” _module_preset=\”default\”][et_pb_column type=\”4_4\” _builder_version=\”4.6.5\” _module_preset=\”default\”][et_pb_text _builder_version=\”4.6.5\” _module_preset=\”default\”] When it comes to installation of Heat Pump (or Solar Thermal) Systems, one of the key decisions ourcustomers have to take is whether they should go for direct or indirect integration of the Heat Pump (orSolar Thermal) system with the existing heat generation system (eg. Diesel Boilers). The obvious advantageof an indirect process heat integration is that since there is no mixing of fluids, maintenance is easy.However, the downside is that it is more expensive. Before getting into more details, let us look at what adirect and an indirect integration means. In a direct integration system, the heat transfer takes place between hot and cold fluids. There are noseparating walls between the fluids. Properties of process fluids such as viscosity, thermal conductivity,specific heat reaction on the metal in contact are essential to determine the pumping thermal requirementand material of construction.Even though the direct integration of a heat pump with process tank looks simple and has higher efficiency,the cost-effectiveness depends on the type of process that requires heat.For example, the hot water generation through direct integration of a heat pump with centralized hot waterstorage tank in hotels will have more cost benefits than the pre-treatment applications in manufacturingindustries. Because in the pre-treatment process, the acidic and alkali solutions are used to treat the metalcomponents by dipping it through a series of process tanks. These solutions are corrosive and colloidal innature requires stainless steel of higher grade as the material of construction for piping components and heatexchanger.In hotels, only raw water is used as a heating medium, which is not corrosive, and scale formed by dissolvedsalts in raw water can be easily cleaned periodically with suitable inhibited acids. However, for using directintegration in a pre-treatment process application, the maintenance cost for frequent cleaning of heatexchangers, strainers and filters will overshoot the indirect integration cost down the road.The direct integration is best suited for hotels, canteens and some industrial applications where rawwater/RO water needs to be heated.

Properties of process fluids such as viscosity, thermal conductivity, specific heat reaction on the metal in contact are essential to determine the pumping thermal requirement and material of construction. Indirect process heat integration differs from direct process heat integration in that an intermediate circuit is used for transferring heat between the two process streams. The transfer medium (water) absorbs heat in one part of the plant and releases it in another. This approach is used when: Direct contact between heat source and heat sink is not allowed. The intermediate circuit works as a safety barrier and leakages can be detected in the loop, before the process fluids mix. Process heat is supplied from long distant Centralized Heating System. Flexibility and reduced interdependence is required. Equipping the intermediate circuit with standby coolers and heaters makes it easier to disconnect a unit operation for maintenance, avoiding interdependence between plants. One heat sink requires multiple heat sources. Indirect process heat integration opens up a vast range of possibilities. Some common applications are: Heating Pre-treatment tanks (Surface Cleaning and Coating Process Tanks) Component Washing Application DG Pre-heating system Any Multi-tank centralized heating system.

Some of the advantages and disadvantages of indirect integration system are listed below:     Conclusion Because of the number of technical and practical constraints in integrating Air/Water Source heat pump with existing heating system, the notion of this talk is to understand all economically and technically feasible opportunities for direct/indirect integration system and then compare them to select the optimal integration solution. The selection of integration type primarily depends on the properties of process fluid and number of tanks to be integrated. Here are some of the common applications that requires heat with best-suited integration system: The following flow chart will give brief idea on selecting proper integration system for heat pump:   Integration Flowchart [/et_pb_text][/et_pb_column][/et_pb_row][et_pb_row _builder_version=\”4.6.5\” _module_preset=\”default\”][et_pb_column type=\”4_4\” _builder_version=\”4.6.5\” _module_preset=\”default\”][et_pb_image src=\”https://aspirationenergy.com/wp-content/uploads/2020/11/flowchart.jpg\” alt=\”Heat pump Integration Flowchart\” title_text=\”Integration flowchart\” _builder_version=\”4.6.5\” _module_preset=\”default\”][/et_pb_image][/et_pb_column][/et_pb_row][et_pb_row _builder_version=\”4.6.5\” _module_preset=\”default\”][et_pb_column type=\”4_4\” _builder_version=\”4.6.5\” _module_preset=\”default\”][/et_pb_column][/et_pb_row][/et_pb_section]

Smart Cities – the new way forward 

/

By 2050, 70 percent of the global population will be city dwellers. This means we need more cities, smart cities at that. Urbanisation although usually a has negative impact on the environment, does not need to be that way. Raj Cherubal, the CEO of Chennai Smart City in the regional WWF Climate Solver organised by Aspiration Energy  talked about the various ways the smart cities are using innovative technologies to help address issues concerning climate change. He discussed a number of planned initiatives that could help move towards sustainability in cities: Parallel Parking Systems   The aim of this project is to provide information on the parking spaces available in the city, and enable neat and and trouble-free parking. This will use IoT to track the availability of some 12,000 parking slots.  Although this system is not intuitively a climate change solution, it can be majorly effective in reducing the number of cars on road – and thereby reducing pollution    Cycle Sharing   Cycles will be made available for rental throughout Chennai,   allowing the people both  the benefits of a healthy lifestyle and also a eco-friendly mode of transport. The cycles will be fit with GPS enables trackers that will be help the people know the availability of these vehicles in their locality. Read more about the initiative here as part of Chennai being a C40 city.    Command and control  This system will help MTC buses ply efficiently thorough the help of intelligent traffic systems. Users can also get the information of the buses in their area and the would suggest the most optimum way to travel to the users.    Clean Sewage  The fourth initiative is to clean sewage under the bridge that are open and near residential areas and convert them into clean water sources and parks for the public   Smart Grids  Smart grids are the systems that could redefine the supply and distribution of both renewable and non- renewable sources of energy. As part of this the charging stations would be installed to enable charging of electric vehicles. TANGEDGO will be able regulate tariffs and play the role of present day petroleum companies.    These systems once in place can significantly help us tackle social, environmental and economical issues on a global level.
