Footprints – Edition 6

Solar Rooftop – Myths vs Reality was the theme for this edition of Footprints conducted on 29 June 2018 at WelcomHotel in Chennai. Sticking to Footprints\’ legacy of being a platform for sharing end-user experiences, this edition also featured participants and speakers from various sectors of the industry, with each organisation bringing in something to the table with regard to energy utilisation. The opening remarks were given by Mr. Bhoovarahan Thirumalai, Chairman, Energy Committee, SICCI, highlighting the importance of footprints and the need for industries to go for greener energy solutions for their manufacturing plants and at the same time the need to provide low costs energy solutions. The event was inaugurated by the Chief Guest, Ms. Mridula Ramesh, who gave a brilliant talk on the pertinent problem of Solar Energy utilisation, and its feasibility for industries. Ms. Mridula stared out her speech with a reminder of the issue of global warming and its impact on the global energy scenario. While India is a significant emitter of greenhouse gases, there is the larger problem of so-called developed countries emitting gases in disproportionately higher rates – an issue that has to be addressed. She also spoke on the need to look for alternatives source of energy – such as Solar Thermal which although are relatively unpopular are ideal for certain applications.   The event also featured a white paper released on the topic of Sustainability and Security in Industrial Energy Use: Hits and Misses on Solar Energy Integration by Prof Satyanarayan Seshadri, IIT- Madras. Prof Satya emphasized on the need to for the most ideal source of energy that would minimise the loss of energy. The end user experiences were shared by Mahindra & Mahindra Limited and TVS Motors. Mahindra had installed a 563 kW Solar PV in the Car parking area – and shared his experiences when installing the system. This reduced their reliance on the grid and reduce their costs significantly. The finance model they used for the installation is based on an ESCO model with the billing being done for the energy delivered to the plant. TVS shared their experience of installing a 225 kW Solar Thermal system for heating their Diesel Generator heads for quick start during cold conditions. The system\’s objective was to reduce the fuel energy costs incurred for heating. TVS turned towards Aspiration Energy for alternative energy sources for their heating needs and deciding on using Solar Thermal systems. They had a look into the working of Solar Thermal systems by a live case from the installation in Harita Seatings in Hosur. The challenges faced during the installation were also shared. The solar thermal has since been monitored constantly and has been proven to save around 60 percent of the energy costs. With this, the TVS motors have been able to reduce massive amounts of carbon emissions as well. But both the talks had a common theme of complexity involved when going green but needing to look at economics on installing the system. The event also witnessed a roundtable discussion that saw interactions among the participants and the speakers. In the end, one thing was sure – that everyone had taken back something from the event – for some it was new networking opportunities, and for some, it was great ideas that they could take back to their organisations to implement to yet again share a story to the world.

Heat Pump demo at UCAL Fuel Systems

UCAL Fuel systems had installed a heat pump in its plants as part of Aspiration Energy\’s rental demo installation to prove the savings of a heat pump. The duration of the demo was from the 21st of November to the 9th of December.   The demo showcased a 14 kW heat pump for one of its vacuum pump line washing machines. It has since proved a savings of 46 %, convincing UCAL that Heat pumps are the way to move forward in terms of sustainable industrial heating solutions for industrial washing machines.   UCAL Fuel Systems was established in 1985 by Carburetors Ltd. (pioneers in India in the manufacture of Carburetors and mechanical fuel pumps) as a joint venture company with Mikuni Corporation Japan – internationally renowned company for fuel management products and are in the business of providing holistic solutions in fuel management systems and is committed to producing products of consistent quality and timely delivery. Aspiration Energy and UCAL after a series of studies, agreed to install it for the vacuum pump line washing machine which perfectly fit our portfolio – with a temperature of 70 C and an actual load of around 7 kW. A brief summary of the demo is given below:   Heaters Units Consumption Average Energy Consumption in Heaters per hour = 6.34 kW Daily Units Consumption = 6.34 kW *24 Hours = 152 Units per day     Heat pump Units Consumption Average Energy Consumption in Heat Pump      = 3.54 kW Daily Units Consumption                                        = 3.54 kW * 24 Hours = 84.96 Units per day Savings Daily Units Savings per day                                    = 157.9 – 84.6                                                                                                                                                            = 73.3 Units Total Units to be saved per month                       = 67.04 x 26                                                                                                                                                                = 2,413 Units per month (For 2 washing machines units = 4,102 ) Total Cost saving per month                                  = Rs.16,894 per month (Cost Saving = 4,102 x 7 = Rs. 28,714) Investment Heat Pump Investment cost                                   = 6.5 Lakhs (Provision for 2 Washing machines) Return On Investment (ROI)                                   = 22.6 Months Accelerated Depreciation Claim                            = 40 % year on year for Energy Saving equipment After AD for 3 years ROI                                          = 16.6 months UCAL and Aspiration Energy now plan on to implement this technology to the rest of the washing machines in Maraimalai Nagar and to other plants thorough out India as well.   Success stories like these are what drives us towards making a greener and cleaner future.

7 Reasons to consider Roof Top Solar Thermal than Solar PV

  Solar Energy is most often implied as Solar Photovoltaic Energy with electric energy as the output.Solar thermal energy is not as predominant in the Solar Renewable energy scenario as Solar PV. Let us consider the current scenario around the world.  The total Solar Thermal Capacity being utilised in the world currently is 465 GigaWatts. This mostly is accounted by small scale and household utilisation. This, when compared to the solar photovoltaic base capacity installed – around 303 GW – is more than 50 percent higher.        Having said that, the industrial utilisation of Solar Heating systems remains paltry. 100 Million Tonnes of Oil is used in Industries for heating applications of which 15 million tonnes are used for below 250°C applications. This amounts to around 93 GW Solar Potential for under 250°C and approximately 20GW potential for under 100°C applications   This is huge in terms of unharnessed solar energy, potentially saving millions of rupees and carbon emissions. We shall now look into this disparity in terms of pragmatic factors.   The cost of Solar Thermal Solutions is more than 1 to 2 crores cheaper for every MW generated using Solar Power technologies. Space occupied by a solar heater is  3000 sq. m whereas 1 MW solar PV takes about 10000 sq. m.. Energy produced by solar heaters in a year also is often more than Solar PV. Why then is  Solar PV still more prevalent?     The reasons vary from low awareness on the potential Solar heating Technologies to the unappealing nature of  Solar Thermal Systems to Low Media coverage on its success.   With governments focusing on more and more sustainable energy solutions these forms also deserve the same attention, if not better, than the usual renewable energy solutions.   In the following series of blog posts posted every Thursday, we shall look into the 7 factors that make Solar thermal Solutions more feasible than Solar Photovoltaic systems and study the processes of implementing these systems.
