Household Energy Efficiency
- Residential sector is one of the biggest consumer segments of power/energy in Bangladesh and the wastage of energy in this sector is very high. So, we need to develop some tools/ applications to increase energy efficiency in home.
- Presuming that 100% electrification will be achieved by 2021, the market penetration rates of electric appliances such as refrigerators, washing machines, ACs and microwave ovens will be very high. So, we have to suggest/ design energy efficient home appliance based on energy pattern.
- Once the population gets electricity & the home appliances are in place, you need to help users to improve ability for monitoring & managing one’s energy consumptions through easily accessible & low cost technology. Now, we need to design such a process to help the consumers to control their electricity usage.
- Integrate the IOT (internet of things) technology with our system to improve energy efficiency/ to enhance the user journey to control electricity usage.
- Introduce eco-friendly building structure to use natural resources such as sunlight/ wind for improving energy efficiency.
- The availability of gas supply is a burning question in these days & it is pointed out that newly built households will have limited access to gas supply. In this circumstances we need to develop some measures to reduce gas consumption.
- Integrating alternate energy sources to different energy source to improve energy efficiency can also be another way to a sustainable power solution. We have to find a way to use different power generation mechanism besides national grid.
- Encouraging user to change their uses behavior reduce the energy consumption. Only the behavioral changes can effectively reduce the consumption of energy in our household activities.
- Bangladesh established its sovereign rights through international court verdicts on more than 118,000 sq km of maritime territory. The Ocean offers enormous potential for the generation of renewable energy – wind, wave, tidal, biomass, thermal conversion and salinity gradients. Harnessing these resources is our main challenge towards a new dimension of power generation.
- We need to design a sustainable and efficient P&E generation process for one of the resources harnessed above.
- The marine energy resource depends on the weather largely. Hence the power generation varies on a daily basis. We need to find a way to integrate this variable power generation unit with the national grid while ensuring quality power.
- Wave resource utilization can be the new source of renewable energy. Once we used to deal with wave for generating power we will get endless opportunity to harness the power and energy.
- Offshore wind produce utilization could be another source of power and energy. Along with this challenge we need to consider that we need to find sustainable ways to reach electricity to the islands and such remote areas.
- Harnessing/ utilization of marine resources can deeply impact the marine life across the Bay of Bengal if we are not careful & can bring a catastrophic result for the whole coastal area. We have to design an environmental friendly process to generate electricity without hampering the natural ecosystem.
- Biomass resource utilization can be a very good option to generate electricity. Design an environmental friendly efficient process to use biomass resource for power generation.
- The data available currently for marine resources are inadequate for large scale power generation. We have to design some tools/ plans to extract data in the deep sea.
- We have to ensure proper surveillance/ security of the resources to protect them from potential misuse. We have to come up with a solid plan for this.
- The industry sector of Bangladesh is the second largest contributor to the GDP of the country, comprising an estimated 30.4% of its USD 226.7 billion GDP. Greater power generation as well as access to electricity is key to fueling the growth of not only key industries but also the growing appetites for the emerging foreign investments. But we have to integrate a modern technology in process engineering to effectively utilize available power.
- We have to check the feasibility of in house power generation to meet the demand in peak hours independent of the national grid. Designing a suitable in house power generation scheme is the main challenge here.
- We need to design a Eco friendly factory/ workplace that uses natural resources.
- Designing a demand- supply balancing techniques in peak & off- peak hours such as shift working can be a potential power utilization mechanism. But the cost effectiveness of this technique can be a prime concern. We have to come up with a cost effective demand- supply balance mechanism for large industries.
- According to various projections, by 2030 our natural gas reserve deplete out will completely which is an alarming concern for the industrial sector. Now the government is trying to diversify the energy mix of the industries with feasible substitutes. We have to design a standard waste management policy to recycle or use for power generation
- We have to have a regulatory body for controlling impact/installation of machinery that draws a large amount of power/ inefficient use. Design such a regulatory policy to enhance the efficiency.
- Power theft is a huge concern for developing countries like ours. Effective distribution of the generated power can reduce power theft/ misconduct. We need to design a topology to monitor the grid power flow.
Clean Cook Stove
- In Bangladesh, Approximately 86% of the population still rely primarily on solid fuels as a domestic source of energy. These fuels are harmful for both the people & nature. So, we need to design an efficient solar cooker or double burner ICS or Biomass stove or hybrid cooker.
- Using alternate fuel (i.e BioGas, easily accessible pellets, solar power) for same stove can increase fuel utilization. Hence, we have to design a stove that can use multiple fuels.
- Design a process to increase stove heat efficiency by generating electricity from the waste heat.
- Designing the ICS is not enough to solve the problem. If we cannot deliver the stoves to our rural people, all the efforts will go in vain. We need to come up with a plan to create demand creation of ICS in both rural & city area in an affordable price.
- We need to design an easy ignition process of stove to make this popular among the mass population.
- Creating pellet in easy & cost effective way is another challenge. If the users do not have affordable pellet availability, they will most likely not to be interested in buying the stove in the first place. So, we have to design a simple, cost effective way to create the pellets for the stove.
- In many rural areas, wood, agricultural waste remains the main fuel. But over 8,500 children die every year in Bangladesh from diseases cause by household air pollution. In this case we need to design some low cost tools/filters to prevent the harmful elements from getting exposed in the environment.
- Solar thermal based hybrid cooker for reducing the consumption of other energy sources.
- Design energy efficient Pot so that heat, steam both can have an efficient cooking mechanism. This pot must be cos effective, preferably very low cost.
- A smart grid may be defined as an electricity delivery system from point of generation to point of consumption integrated with ICT for enhanced grid operations, customer services and environmental benefits. We need to design a system to integrate small scale power generators with the national grid which will automatically sense the power flow variations & take measures.
- To implement a smart grid we need major restructuring of our generation & distribution system to work in sync. We need to design a cost effective restructured model which will have minimum impact on the existing infrastructure.
- The smart grid consists of various components to maintain quality power from the point of generation to the consumer’s end. We already have SCADA implemented in our system but it is inefficient without the supporting devices. We need to design components like automated frequency management or smart meter etc.
- We need to develop some tools/ applications for the consumers to control their power usage.
- In the big data server, all the usage pattern of a particular user will be available. We need to find a way to analyze these behavioral load patterns & our generation need to be matched accordingly.
- In this smart grid all the data of all consumers will be stored in a centralized server. Any kind of breach in this server can lead to a catastrophic result. We need to develop a system to ensure the information/ cyber security of our data.
- We have to design some smart appliances for the system. These appliances should be sensitive to power flow variation & able to adjust them accordingly.
- The government of Bangladesh is planning to generate 220 megawatts of electricity for around 6 million households by 2017 through the solar home system programme. We need to design a solar panel system with improved efficiency.
- DC appliances have low loss mechanism & hence is more efficient. But the production of DC appliances is very challenging. So, we need to have a plan for development of cost effective local manufacturing process for DC appliances.
- The conventional battery storage system of a solar powered system has a very high loss & is also hazardous for our environment. We need to design an environmental energy storage facility.
- We need to look for alternate energy sources for power generation. Check the feasibility of wind or biomass or wave/ tidal energy project.
- In many rural and hilly areas, it is very difficult to set up distribution infrastructure. In these cases, we need to develop decentralized projects depending on locally available renewable energy resources.
- Karnaphuli hydroelectric power plant is one of the major generation source in our country. We need to check the feasibility of installing modern technologies to increase it’s efficiency.
- The government has determined targets of 1370 MW of wind power by 2021. We need to design a cost effective technology to meet this target.
- Improving revenue collection through better technology so that it ensures the collection of revenue in proper time and manner and all the users pay accordingly.
- Developing solutions to overcome land limitations since Bangladesh is having lots of rivers, chor areas and hill tracks where reaching power is still a challenge. The 20% of population who are not getting the benefit of electricity are mostly because of this scenario. So we must have solutions to overcome land limitations.
Affordable access to electricity
- To date, the power generation capacity is 15000 megawatts. 80 percent of the country’s population has access to electricity. We need to innovate a new technology to bring the other 20 percent under the privilege of electricity.
- The government has set a target to bring the 20 percent population under the privilege of electricity in 2 years. We have to design a cost effective infrastructure model for electricity providers in rural areas with minimum impact on the existing infrastructure.
- In many rural and hilly areas, it is very difficult to set up distribution infrastructure. In these cases, we need to develop decentralized projects depending on locally available energy resources.
- Recycling waste to produce electricity is both efficient & environment friendly. So, we need to design a waste management for energy production so that we can meet the demand of the hardly accessible locality by the local wastes.
- Small power generation unit can be an effective way to deliver electricity to the rural area. But cost & efficiency are the main challenges in this solution. We need to development some means of local manufactured small scale power generation unit so that the rural people can afford them.
- The government of Bangladesh has taken initiative to facilitate electricity to the 20 percent rural population that are still out of electric facility in the next 2 years. To do that we have to set up a distribution system in those are to deliver electricity from the national grid. So, we need to design a low cost distribution system for remote areas.
- In many rural areas, maintenance work in the distribution system is very tedious & difficult due to underdeveloped road network. As a result, in case of a fault, many localities are cut out of electricity for days. An automated fault detection & prevention system can come in very handy in this type of scenario. So, we need to design an automated fault detection & prevention system for our distribution network.
