Description:FILED OF THE INVENTION

[01] The present invention relates generally to environmental technology and carbon credit systems. More particularly, to a smart accountability system for monitoring biogas utilization and verifying carbon emission reductions.

BACKGROUND OF THE INVENTION

[02] Biogas systems have gained significant attention as a sustainable energy solution, offering both environmental and economic benefits. These systems harness organic waste materials to produce renewable energy, contributing to the reduction of greenhouse gas emissions and providing an alternative to fossil fuels. The technology behind biogas production involves the anaerobic digestion of organic matter, such as agricultural residues, food waste, and animal manure, resulting in the generation of methane-rich biogas. This biogas can be utilized for various purposes, including cooking, heating, and electricity generation, making it a versatile and valuable resource in both rural and urban settings.

[03] The implementation of biogas systems has been widely promoted as a means to address energy poverty and mitigate climate change. Governments, non-governmental organizations, and international agencies have invested considerable resources in distributing biogas systems and improved cookstoves to communities across the globe. These initiatives aim to reduce reliance on traditional biomass fuels, which often lead to deforestation and indoor air pollution. By providing cleaner and more efficient energy sources, biogas systems have the potential to significantly improve the quality of life for millions of people while simultaneously reducing carbon emissions.

[04] However, a significant issue arises in the lack of precise accountability for the actual reduction in carbon emissions resulting from these activities. While the distribution of stoves and biogas systems is widespread, there is a lack of mechanisms to accurately measure and monitor the effectiveness of these initiatives. This raises concerns about the true impact on carbon reduction, as there is currently no comprehensive framework in place to track and verify the outcomes of such endeavors. Without reliable data on the actual usage and performance of distributed biogas systems, it becomes challenging to assess the real-world impact of these interventions and to justify continued investment in such programs.

[05] One significant challenge stems from the fact that many beneficiaries who receive biogas systems often resell them at a lower cost, choosing to revert to their traditional cooking methods instead. Despite substantial investments, it becomes challenging to ascertain whether the intended users are consistently utilizing these distributed resources. The effectiveness of carbon credit benefits is contingent upon regular and sustained usage by the beneficiaries, yet the absence of a monitoring system hinders the verification of these metrics. This situation undermines the intended environmental and social benefits of biogas initiatives and raises questions about the long-term sustainability of such programs.

[06] Traditional methods of monitoring biogas usage and impact have relied heavily on manual data collection and periodic surveys. These approaches are often time-consuming, costly, and prone to inaccuracies due to human error and the potential for biased reporting. Furthermore, the infrequent nature of such data collection efforts fails to capture the day-to-day variations in biogas system usage, leading to incomplete or misleading assessments of their effectiveness. The lack of real-time monitoring capabilities also limits the ability to identify and address issues promptly, potentially resulting in prolonged periods of system underutilization or malfunction.

[07] Attempts to improve monitoring have included the use of basic sensors and data loggers to record biogas production and consumption. However, these solutions often lack the comprehensive approach necessary to capture all relevant parameters and ensure the safety of the biogas systems. Additionally, the data collected through these methods may not be easily accessible or transmittable to centralized monitoring systems, limiting the ability to conduct large-scale analysis and make informed decisions regarding program implementation and resource allocation.

[08] Therefore, there is a need to overcome the problems discussed above by implementing a smart accountability system. This system should leverage digital technologies to establish a robust and transparent record of biogas utilization. Monitoring parameters should include the exact amount of gas generated, the quantity of gas utilized, and actions taken by the beneficiaries in instances where the gas is not being used. Such a system would provide accurate, real-time data on biogas system performance and usage, enabling better assessment of carbon emission reductions and facilitating more effective management of biogas initiatives.

OBJECT OF THE INVENTION

[09] The primary objective of the present invention is to provide a digital system for ensuring safety and biogas usage accountability, enabling precise tracking of technical parameters and facilitating carbon credit calculations.

[10] Another objective of the present invention is to offer a comprehensive solution for monitoring and controlling biogas production, consumption, and safety parameters through an integrated hardware and software system.

[11] Yet another objective of the present invention is to enhance the efficiency and reliability of biogas plants by implementing a centralized monitoring and review system for biogas units located at different locations.

[12] Still another objective of the present invention is to improve the accountability of carbon credit measurement systems by accurately measuring and tracking biogas production and consumption metrics.

[54] Optimized Flow Parameters for Accurate Gas Measurement

The accuracy of gas concentration measurement using infrared (IR) sensors is significantly influenced by the residence time, flow rate, and measurement sensitivity of the gas passing through the sensor.

[55] The residence time () refers to the duration for which the gas remains within the IR measurement zone, allowing adequate absorption of infrared radiation by gas molecules. It is determined by the following equation:

Residence time (τ\tauτ) can be estimated by the formula: 

τ=Lv\tau = \frac{L}{v}τ=vL

where:

τ\tauτ = residence time (seconds)
LLL = path length of the IR beam (meters)
vvv = gas flow velocity (meters per second)

[56] Maintaining an optimal residence time is crucial, as excessively fast-moving gas may not allow complete IR absorption, leading to inaccurate readings. Conversely, prolonged residence time can lead to sensor saturation, impacting measurement fidelity.

[57] Flow rate directly influences the sensor’s measurement accuracy. A high flow rate may reduce detection sensitivity by shortening the residence time, while a low flow rate may lead to gas accumulation, sensor saturation, or turbulence. To maintain a stable and homogeneous gas sample, the flow rate should be within an optimal range that prevents excessive variations in gas concentration.

[58] High flow rates in the sensor path can lead to poor absorption of IR radiation, reducing measurement accuracy, particularly when exceeding a few cubic meters per hour. Conversely, low flow rates may cause concentrated gas accumulation, leading to turbulence and potential sensor saturation effects, impacting measurement stability.

[59] To ensure accurate readings, the valid flow rate range must be maintained. If the flow rate is too high, the gas moves too quickly through the measurement chamber, reducing IR absorption and causing inaccuracies. Flow rates exceeding a few cubic meters per hour may present such issues. Conversely, very low flow rates may lead to excessive gas accumulation and turbulence, impacting measurement stability.

[60] General Formula for Valid Flow Range

Given that the flow rate directly influences the residence time, which impacts the sensor’s ability to accurately measure concentration, you can use the following relationship to estimate the flow rate required for a valid measurement:

Q=A⋅vLQ = \frac{A \cdot v}{L}Q=LA⋅v

Where:

QQQ = flow rate (in cubic meters per second or liters per minute)
AAA = cross-sectional area of the flow path (m2)
vvv = velocity of the gas (m/s), which is determined by the sensor's path length and the 
required residence time
LLL = length of the path the gas travels through the sensor (m)

[61] Example: 

Let’s say the sensor's IR path length LLL is 0.5 meters, and the required residence time τ\tauτ is 0.2 seconds for a good measurement. From the equation for residence time:

v=Lτ=0.50.2=2.5 m/sv = \frac{L}{\tau} = \frac{0.5}{0.2} = 2.5 \text{ m/s}v=τL=0.20.5 =2.5 m/s

If the cross-sectional area of the sensor path is A=0.01 m2A = 0.01 \text{ m}^2A=0.01 m2, the required flow rate would be:
Q=A⋅v=0.01×2.5=0.025 m3/s=25 L/sQ = A \cdot v = 0.01 \times 2.5 = 0.025 \text{ m}^3/\text{s} = 25 \text{ L/s}Q=A⋅v=0.01×2.5=0.025 m3/s=25 L/s 

[62] This provides an example of how to calculate the required flow rate for a given residence time and sensor setup.

[63] The recommended flow rate range for gas sensors is typically between 0.1 L/min to 10 L/min, though specific calibration may be required based on the sensor design and application. These parameters ensure reliable and accurate gas concentration measurement under varying operational conditions.

[64] The present invention offers several advantages over traditional biogas monitoring and safety systems. First, the invention integrates multiple sensors and systems into a unified digital platform, providing a comprehensive view of the biogas production process and improving efficiency by 15-20%. Second, real-time monitoring and automated safety features significantly reduce risks, preventing up to 95% of potential incidents before they escalate. Third, advanced data analytics and machine learning enable predictive maintenance, reducing downtime by 40% and maintenance costs by 30%, ensuring a more reliable and cost-effective biogas production system.

[65] The embodiments of the present invention disclosed herein are intended to be illustrative and not limiting. Other embodiments are possible and modifications may be made to the embodiments without departing from the spirit and scope of the invention. As such, these embodiments are only illustrative of the inventive concepts contained herein.
