By Shalini Nagar


The future of energy generation is a critical topic that requires our immediate attention.  As the global population continues to increase so does the demand for energy. According to our projections, there will be a rise in global electricity generation by 2050 ranging from 30% to 76% compared to the levels of 2022.

Over fifty years, there has been a consistent growth in electricity consumption worldwide reaching approximately 25,500 terawatt hours in 2022. However, we must recognize that traditional energy sources like fossil fuels are not sustainable and have negative impacts, on the environment. Therefore, it is crucial that we prioritize finding efficient solutions to fulfill our energy requirements.

Renewable Energy: What We Need


Solar bio-gas hybrid power systems represent an advancement in the field of energy generation. Through the fusion of energy and bio-gas, these systems provide an environmentally friendly and effective solution to the ever-increasing global energy needs. It has been observed that in 2021 the combined production of bio-gas and biomethane yielded an amount of 196 TWh or 18.4 bcm of energy in 2022.

Solar power, derived from the sun, is a clean and sustainable form of energy. It is captured using photovoltaic panels that convert sunlight into electricity. As per the International Energy Agency’s predictions, solar power will experience growth in the next five years and is expected to generate an additional 1,200 GW of electricity by 2025.

On the other hand, biogas is a renewable energy source created through the decomposition of organic matter like agricultural waste, food waste, and sewage. It can be used for purposes such as heating, cooking, and generating electricity. It was observed that the global installed capacity for biogas reached 22 gigawatts in 2022.

The combination of energy and biogas in hybrid power systems offers numerous advantages. Firstly it ensures a consistent and reliable energy supply compared to standalone solar or biogas systems since solar energy can be harnessed during daylight hours while biogas production can be continuous. Secondly, integrating these two sources enhances efficiency and reduces dependence, on fossil fuels.

Lastly, hybrid systems that utilize both power and biogas contribute to reducing greenhouse gas emissions and promoting a greener and more sustainable future. According to the National Renewable Energy Laboratory solar energy has the potential to decrease carbon emissions by 1.5 gigatons annually by the year 2050. This reduction is equivalent to the annual emissions produced by, around 360 million cars.

The Technology Behind Solar Power Generation


Solar power generation is the process of converting sunlight into electricity through the use of photovoltaic (PV) cells. These cells, typically made of semiconductor materials like silicon, which absorb photons from the sun and release electrons. These free electrons then generate a current, which can be harnessed to power homes, businesses, and even entire cities.

A solar power system consists of key components; PV panels, inverters, and a battery storage system. PV panels are usually installed on rooftops or in solar farms to capture sunlight effectively.

Inverters play a role by converting the direct current (DC) electricity produced by the PV panels into alternating current (AC) enabling it to power electrical appliances. Lastly, a battery storage system allows for excess electricity generated during periods to be stored for later use during cloudy days or, at night.

Solar Bio-gas Hybrid Power Systems


Solar bio-gas hybrid power systems are a combination of energy generation and bio-gas production. These systems include solar panels, bio-gas generators, and energy storage units. Operating such systems necessitates thoughtful contemplation of various aspects, including system components, integration, with current power grids, and the environmental consequences.

Hybrid Power System Design 


Combining the solar and power generation of bio-gas in a hybrid system is a way to maximize energy production and ensure reliability. By integrating and optimizing the operation of these two systems, it can create a stable and sustainable source of energy. The research findings indicate that adopting this approach can meet, up to 57% of the load using renewable resources. The maximum fraction of energy is found to be 0.600 with a maximum penetration rate of 810%.

System Integration

Integrating solar and bio-gas power systems involves the connection and compatibility of both systems. This encompasses the creation of a hybrid controller responsible for managing the flow of power between the two sources as well, as the storage and distribution of energy.

Optimization of Operation

To maximize the efficiency and performance of a hybrid power system and make it work efficiently it is important to optimize how it operates. This involves figuring out the balance between solar and bio-gas power generation considering factors like the amount of sunlight available the capacity to produce bio-gas and the demand for energy.

Moreover, sophisticated control algorithms can be used to regulate the power output, from each source in real time guaranteeing a steady and dependable supply of energy.

System Performance

A well-designed hybrid power system has benefits in terms of energy production and dependability. By integrating bio-gas and power generation, it can leverage the unique advantages of each source while addressing their respective limitations.

During daylight hours solar power can deliver renewable energy whereas bio-gas power can provide a consistent and dependable energy supply regardless of weather conditions. This combination ensures a reliable and sustainable energy source reducing dependence on a single power source and enhancing the overall resilience of the system.

Innovative Approaches to Enhancing Bio-gas Hybrid Power Systems
