Forms and Benefits of Grid Storage of Energy

on 19/06/2023

The amount of electricity produced fluctuates depending on the time of day, moon phase, season, and uncontrollable variables like the weather. Energy derived from solar, tidal, and wind source naturally varies on time scales ranging from minutes to weeks or longer. Therefore, renewable poses unique difficulties for electric utilities in the absence of storage. While connecting numerous independent wind sources helps lessen overall unpredictability, solar power is invariably unavailable at night and tidal power fluctuates with the moon, resulting in four times per day of slack tides. Coal, biomass, natural gas, and nuclear power generation that relies on energy stored in fuels must be ramped up and down in an electrical grid without energy storage to keep up with the rise and fall of electrical production from intermittent sources (see load following power plant). Nuclear and coal power facilities have a very long time to adjust to load, whereas hydroelectric and natural gas power plants may be quickly scaled up or down to follow the wind. Demand management, grid interconnections, or pricey pumped storage are therefore more frequently used by utilities with lower levels of natural gas or hydroelectric power.
The ability to store energy at peak output, release it during peak demand, and use it when production unexpectedly drops has made commercially feasible projects possible. This gives time for slower-responding resources to be brought online. Peaking power plants and demand response, which shifts load to other times, are two alternatives to grid storage. The unpredictability of wind energy has had regional effects that have increased the requirement for interactive demand response, where the utility interacts with the demand. Historically, only large industrial customers were involved, but this practice may now be used for entire grids.
For grid-scale applications, a variety of energy storage technologies (such as pumped-storage hydroelectricity, electric batteries, flow batteries, flywheel energy storage, and supercapacitors) are suitable, although they have different properties. For instance, because of their large capacities and power capabilities, pumped-hydro stations are suitable for applications involving bulk load management. However, there aren’t many ideal places, and when dealing with concerns with localized power quality, their value wanes. Flywheels and capacitors, on the other hand, are the best at preserving power quality but do not have enough storage space to be used in bigger applications. The applicability of the storage is naturally constrained by these restrictions. In the early days of direct current electric power, battery storage was utilized. Isolated lighting plants powered by internal combustion engines or wind turbines provided lights and power to tiny motors in areas where AC grid electricity was not easily accessible. When the wind was quiet or when the engine wasn’t running, the load could be powered by the battery system. Lamps were lit, and an engine was started to replenish a bank of lead-acid batteries that were housed in glass jars. For more recent lithium-ion devices, battery storage technology is typically between 80% and more than 90% efficient.
Power distribution networks have been stabilized using battery systems coupled with massive solid-state converters. A few grid batteries are situated near renewable energy sources, either to smooth the erratic power from wind or solar production or to shift the power output to other times of the day when the renewable source cannot directly supply power.
Technologies used in the automotive industry rely on solid electrodes, which have a high energy density but expensive manufacturing processes. Since they don’t require any processing, liquid electrodes are a less expensive and dense option.

CLIMATE ISSUES IN PAKISTAN
Pakistan is a country that is vulnerable to various climate issues due to its geographic location and socio-economic conditions. The 2022 Pakistan floods mainly caused by increased precipitation and glaciers melting fueled by climate change, destroyed around 50% of the crops of Pakistan which can lead to food shortages. Some of the major climate issues in Pakistan are:
Water scarcity: Pakistan is a water-stressed country, and climate change is exacerbating the situation. The country heavily relies on its rivers and glaciers for its water needs, but due to global warming, the glaciers are melting at an alarming rate, which is leading to a reduction in the water flow of rivers.
Floods: Pakistan is also prone to frequent and severe floods, which can cause widespread devastation. Floods are becoming more frequent and intense due to climate change, and they can result in the loss of lives, infrastructure damage, and displacement of people.
Heatwaves: Pakistan is experiencing more frequent and intense heatwaves due to climate change. These heatwaves can cause heatstroke, dehydration, and even death, particularly among vulnerable groups such as the elderly, children, and outdoor workers.
Droughts: Droughts are becoming more common in Pakistan due to changes in precipitation patterns, which are causing water scarcity and affecting agriculture. This can result in food insecurity and economic losses for farmers.
Glacial retreat: Pakistan has one of the largest glaciers outside the polar regions, and these glaciers are melting at an alarming rate. This melting is causing the formation of glacial lakes, which can burst and cause floods downstream.
Sea level rise: Pakistan has a long coastline, and rising sea levels due to climate change can cause coastal erosion, loss of land, and damage to infrastructure.
The government of Pakistan is taking steps to address these climate issues, such as developing climate policies and implementing adaptation measures. However, more needs to be done to address the root causes of climate change and reduce its impacts on the country.
ACTIONS TO REDUCE IMPACT OF CLIMATE CHANGE
Several actions can be taken to address climate issues in Pakistan. Here are a few examples:
Promote renewable energy: Pakistan can invest in renewable energy sources such as solar, wind, and hydropower. This can help reduce its reliance on fossil fuels and lower greenhouse gas emissions.
Increase forest cover: Pakistan can increase its forest cover by planting more trees, which can help sequester carbon and reduce the impact of climate change. This can also help reduce soil erosion, improve air quality, and provide habitats for wildlife.
Improve water management: Pakistan can improve its water management by promoting water conservation, building water storage infrastructure, and implementing efficient irrigation practices. This can help address water scarcity and reduce the impact of floods and droughts.
Promote sustainable agriculture: Pakistan can promote sustainable agriculture practices such as conservation farming, crop rotation, and organic farming. This can help reduce greenhouse gas emissions, improve soil health, and increase food security.
Build climate-resilient infrastructure: Pakistan can build infrastructure that is designed to withstand the impacts of climate change, such as floods and sea level rise. This can include building flood barriers, improving drainage systems, and relocating vulnerable communities.
Raise public awareness: Pakistan can raise public awareness about the impact of climate change and promote actions that individuals can take to reduce their carbon footprint. This can include promoting energy conservation, reducing waste, and using public transportation.
These actions require a collaborative effort between the government, private sector, and civil society to address climate change in Pakistan.
