I went to attend a conference at the Jinnah Convention Center Islamabad last year, where a government university proudly presented a model to deal with the energy crisis and a Pakistani government institution donated a huge amount of money for this research. Had also issued
Upon my inquiry, the proponent stated that the project attempted to generate electricity by utilizing the heat extracted from the factory fireplace.
I realized that this is not an effective and sustainable project. So instead of researching photovoltaic and voltage storage I wanted to know the reason why I preferred the proposed project, which I could not find a satisfactory answer.
Similarly, a German scientist with a patent is trying to promote thermal solar technology in Pakistan. And an important government agency in Pakistan is engaged in research. The scientist has also set up a MW power plant in India with the help of thermal solar. Only one megawatt !!! An energy expert working in a cement company in Germany told me that thermal solar is a rejected technology. And the energy sector of Cement has shrunk back to billions of rupees. According to the same expert now working on thermal solar, a new market has been discovered in the sub-continent. Accordingly, this technology has several limitations that make it unable to offer an effective solution to the energy crisis.
A similar effort is also being made with regard to biomass energy (in which electricity is generated by burning the remains of plants and animals). Biomass energy advocates say the technology may play a significant role in the energy crisis, but social scientists have several concerns. In our rural system, the farmer will not prefer to produce electricity by burning any biomass. If he burns wheat straw or straw, where will he get the straw for the animals? In the same way, cotton sticks are used to burn stoves in homes in rural areas. This is the case with other remains. For a moment, even if we assume that the farmer will agree to burn the rest, the question is how much electricity can he produce? That’s the question I asked a PhD scholar doing biomass research. He told me that if we utilize all the agricultural biomass produced in Pakistan and generate electricity, more than four thousand megawatts of electricity will be generated. Agricultural biomass of entire Paksan and only four thousand MW? So brother, why do you need so much?
The Beau gas case is no different. Although the Punjab Government is particularly committed in this regard and has allocated a large sum of money for the promotion of biogas tube wells, but I am concerned that this capital will not be sank. A recent social research has revealed that home-grown biogas plants in the villages suffer from lack of sufficient dung. I am afraid that the farmer will soon be able to overtake this technique by being fed up with the hard work of collecting, folding and reversing it. Additionally, the gas produced is extremely inaccessible to the generator. If this gas purification plant was set up, it would have become an expensive and complicated project, which is a major obstacle to the adoption of this technology.
So the question is, what is the solution to this crisis and what should be our research direction?
The solution to this, in my view, is that our research should focus on solar energy, hydro energy and wind energy.
There is a sustainable solution to solar energy, but there are two aspects to this. Number 1 Create a solar cell that is compatible with our climate. That is, when the temperature is high, its capacity to generate electricity should increase rather than decrease. It should be noted that there is a defect in the current solar cell that when the temperature rises, its production capacity decreases.
Develop an inexpensive and sustainable energy storage technology. The question of energy storage is a big challenge for energy experts right now. Many government and non-governmental organizations have been researching it at the international level, but no breaks have been made in this regard.
Existing energy storage techniques are extremely expensive and unsustainable.
This can be said of both liquid and dry batteries. Of course, lithium-ion batteries (battery technology used in mobiles) are long lasting but they are very expensive. Research should be done to make it cheaper.
If we use the existing storage system, it will increase the cost of electricity. This is exactly what we did at Quaid-e-Azam Solar Park, where the cost of electricity is estimated to be about Rs. 20 per unit.
But even if we are able to build cheap and climate-compatible solar cells, there may be a breakthrough in the energy crisis, despite the lack of effective storage systems, as Australia and European countries have done. Instead of storing them directly in the grid line. This will provide very cheap electricity at a time of scorching heat and the other common man can sell solar power to the government by installing solar panels at the domestic level. The government has decided in principle to adopt this procedure
