Airier: Biomass Pellets, Stove & Burner in India

  • Tuesday, 26 May 2015
  • by
  • Rajesh K
  • I met the representatives of Airier Natura Private Ltd, during the recent Green Summit 2015 renewable energy expo at Bangalore. They are the manufacturers of Biomass Pellets, Biomass Stove & Biomass Burners in India.

    What are Biomass Pellets?

    Biomass Pellets are a type of fuel that releases heat energy when burned. These are packed densely and have a low moisture content (less than 10%), hence they can burn with high efficiency. Biomass pellets are available in different sizes like 6mm, 8mm, 10mm, 20mm, etc. 

    They are generally made from compacted/compressed biomass like sawdust, wastes from wood products manufacturing, left over tree felling, palm kernel shells, groundnut shells, coffee husk, etc. Different types of biomass pellets are available for commercial and industrial applications.

    Biomass Pellet Stove:

    The Biomass pellet stove burns biomass pellets in a more efficient manner. There are two types: Natural Draft, Forced Draft (that use fans, etc.) There are different biomass stoves for different applications like domestic & commercial, respectively.

    Biomass Pellet Burner:

    Biomass pellet burner uses biomass pellets as fuel and is intended to replace oils and fossil fuels to provide energy to boilers and furnaces in a variety of industries. There are different types of biomass burners, depending on the application.

  • Rajesh K
  • During the recently concluded HYREX 2015 in Hyderabad, I visited the stall of a company called Sukhila Power Electronics. They had displayed their Hybrid UPS there, and I noted their company website to get more information on their solar products. When I visited their website, I found an interesting product that could be useful to renewable energy installations that use batteries to store energy: Battery Health Monitor!

    Their website says that their Battery Health Monitor can monitor up to three strings of VRLA, Lead-Acid, and LMLA Batteries, each string supporting up to 24 batteries/cells. It seems this is a micro-controller based system that can test and display various battery parameters manually or automatically (at programmed intervals). It can monitor each battery, and can identify failing/failed batteries so that they can be replaced. There is also an auto monitoring mode through MCM (Monitoring and Control Module) and remote monitoring. 

    The system can read and display battery parameters like voltage, temperature, conductance, string voltage, current, etc. 

    For further details, refer to Sukhila Power Electronics Product page.

    Land Mark Solar: Solar Petrol Pumps in Telangana & AP

  • Wednesday, 8 April 2015
  • by
  • Rajesh K
  • During the recently concluded HYREX 2015 Renewable Energy Expo at Hyderabad, I met the representatives of Land Mark Solar, the suppliers for Solar Petrol Pumps in Telangana & Andhra Pradesh. They also offer other services in the renewable energy segment like EPC, Solar Panel solution for organizations, etc. In this article, let's focus on their Solar Petrol Pump solution. 

    Petrol pumps are located everywhere - both in rural and urban areas. But they may not get adequate power through the grid always as long power cuts are common in areas outside the big cities. They generally employ diesel generators to compensate for these power cuts, but even for petrol pumps, that can be an expensive proposition on the long run!

    Hence it maybe a good idea to install solar panels to power petrol/Diesel pumps.

    Following is the summary of the Solar Petrol Pump solution offered by Land Mark Solar. (They provide Solar Panels made by HBL Solar, the large Govt. PSU.)

    Petrol/Diesel Pump Type: 2 Nozzles, 1 Petrol and 1 Diesel, 0.75 HP Pump ::: Solar Power plant of capacity 1440Wp size with 4 hours battery back up; Suitable PCU with high crest ratio & module mounting structure. 

    Petrol/Diesel Pump Type: 4 Nozzles, 2 Petrol and 2 Diesel, 0.75 HP Pump ::: Solar Power plant of capacity 2400Wp size with 4 hours battery back up; Suitable PCU with high crest ratio & module mounting structure. 

    Petrol/Diesel Pump Type: 2 Nozzles, 1 Petrol and 1 Diesel, 1 HP Pump ::: Solar Power plant of capacity 1440Wp size with 4 hours battery back up; Suitable PCU with high crest ratio & module mounting structure. 

    Petrol/Diesel Pump Type: 4 Nozzles, 2 Petrol and 2 Diesel, 1 HP Pump ::: Solar Power plant of capacity 2400Wp size with 4 hours battery back up; Suitable PCU with high crest ratio & module mounting structure.

    They told me that they have completed a few solar petrol pump projects in Telangana & AP. So if you are interested to power your petrol/solar pumps through solar energy, and you are located in this region, you might want to consider Land Mark Solar for your project.

    Concentrated Photovoltaic (CPV) in India: Chroma Energy

  • Wednesday, 1 April 2015
  • by
  • Rajesh K
  • Chroma Energy is trying to make Concentrated Photovoltaic (CPV) Technology available in India. This, when combined with solar trackers, can dramatically improve the efficiency of solar cells/solar systems, they say.

    The two dominant technologies to generate solar power today are Crystalline and Thin Film Solar PV. Solar Thermal is also there, but the adoption/efficiency is lower. CPV is a relatively new technology that uses optics to concentrate sunlight on small and efficient solar cells. These systems are not only smaller, but their energy conversion ratio/efficiency is significantly more than silicon-based PV technologies. The technology brief is here.

    Some benefits of CPV:
    • CPV requires less land than Solar PV (for the same capacity).
    • CPV is not water intensive. 
    • CPV has a lower energy payback period.
    • Since they are high-mounted structures, land below them can still be used for other purposes.
    • Suitable for countries like India that have high irradiation levels at many places. 
    • If manufactured in India, which has the capacity and the ecosystem, a number of jobs and ancillary industries will be supported. 
    Let's hope the company will bring CPV technology to India; start producing and generating electricity through CPV panels, soon. This technology looks exciting and promising to me.

    Single Axis Solar Trackers in India: Scorpius Trackers

  • Tuesday, 31 March 2015
  • by
  • Rajesh K
  • Single Axis Solar Trackers from Scorpius Trackers in India, Introductory Video:



    Scorpius Trackers, based out of Pune - India, is the manufacturer of Single Axis Solar Trackers that automatically and continuously track the sun, and rotate solar panels to face the direction where sunlight exposure is maximum, from morning to evening. Solar trackers increases the energy generated (per panel) and hence decreases the land required for a solar plant project. The company claims that energy output over fixed PV increases by 18 - 25%, for a corresponding increase of 9 - 12% Capex per MW. I met the company officials during the recently concluded HYREX 2015 Renewable Energy exhibition at Hyderabad. 

    According to their brochure, their solar tracker system calculates the position of the sun using various algorithms and determines the optimum rotation angle every minute. It also adjusts the tracker tilt based on the Solar AZIMUTH, and back tracking tries to avoid shading of the rows of PV modules on the shaded side. When the tracker detects high wind speed it can reduce its presented cross section to the wind, hence reducing the force on the mechanical structure. This is called tracker stowing.

    The tracking system can be operated using an AC source (Grid) or using the power generated by the Solar modules themselves. They say one 250W module is sufficient to power a 250 kW tracker block. Also, the integrated battery in the controller maybe sufficient for tracker movement for up to 5 days, in case of temporary non-availability of external power. The company says that the pay back on tracker investment is less than 3 years. 

    Scorpius Trackers manufactures single axis trackers with 100% frictionless pivots, no bearings, no bushes, no lubricants - hence reducing maintenance requirements. The solar trackers are mostly used in large solar plants, but can also be used for stand alone ground-mounted/roof-top installation like trackers for solar pumps. 

    Further Information/Company Website: Scorpius Trackers.

    Disclaimer: This website is not associated with the above mentioned company in anyway. Readers are encouraged to do proper research and evaluation of both the company and their products before deciding to buy them.

    Turn your Kitchen Waste into Biogas for Cooking!

  • Wednesday, 25 March 2015
  • by
  • Rajesh K
  • In the kitchen (and sometimes outside it) we produce a lot of organic waste. When we mix this waste with plastics, metal, chemical waste and send it to a landfill, it not only creates a lot of pollution but also makes it difficult to separate and recycle waste. All the smell from the dustbins/landfills are caused due to this organic waste from kitchen, mostly. 

    So can we do anything about it?

    Yes. We can collect organic waste (food waste, vegetable peels, fruit leftovers, cooked meal leftovers, etc.) and inorganic waste (plastic, metal, etc.) in separate dustbins and deposit only the inorganic waste in the dustbins/dumps. 

    But what do we do with the Organic waste?

    Turn it into money! You can generate both biogas for cooking and compost for plants in the garden if you deposit the organic waste into a biogas digester plant.

    But aren't the biogas digester plants very big & require a lot of space?

    Some are, not all. There are small biogas digester units for homes/families too. For example, a 1m3 (one meter cube) biogas digester plant requires a space of 4 x 5 feet only. It generates 1m3 of biogas when 6 - 10 Kgs of organic waste is digested by it, which gives a continuous flame for 2 hours. The biogas stove/burner is separate from (but similar to) the normal LPG stove/burner and requires simple piping system for carrying the gas. It may not replace LPG cylinders but can reduce the no. of LPG cylinders required for a family. 

    What about Compost?

    After organic material is digested, compost will come out of the digester (as a byproduct) which is mixed with water and can be used as manure for home/kitchen garden. Note that this byproduct may induce some smell and hence need to be stored in closed containers. However, there will be no smell coming from the main unit unless there is a leak. There is no need to buy or make compost for your garden/kitchen garden if you have this system.

    Can I Install it in my House?

    Yes, if you have some space - preferably open space exposed to sunlight - you can install this unit in your house/terrace. 

    Of course, there are separate (larger) biogas plants for organizations like eateries, hotels, etc. that generate a lot of organic waste. 

    If you live in Chennai, have a look at B-Sustain who offer Biogas Digester plants in varying capacities. Or you can contact Vibrant Marketing if you have any sales enquiries.

    Please note: This website is not affiliated with the above mentioned companies in anyway. I am just trying to help spread the word as the product generates biogas, which is renewable energy. Readers are requested to verify & evaluate the products and services offered thoroughly before buying.

    In this blog, I am taking baby steps to enable myself (and others) to adopt renewable energy technologies. Only if we know all the options available to us, we will be able to take informed and meaningful decisions, right?

    Let us learn what renewable energy technology options we have, who provides them and at what cost.

    Frankly, renewable energy in India (and perhaps the world) is still in its adolescence - Let us help it become a confident Man/Woman! And in the process, let us debate, analyze, form opinions and break them so that we can achieve the Utopian dream of Energy Security through Renewable Energy. Are you with me?
