Modeling and analysis of solar thermal and biomass hybrid power plants

  • Modeling was performed for solar thermal-biomass hybridization for power generation.

  • Increment in capacity reduces the solar collector area per MW to 5,000 m2 (20 MW).

  • Annual biomass requirement per MW reduced to 1600 tonnes at 20 MW scale.

  • Hybrid mode of operation increases the plant capacity utilization from 23% to 47%.

  • Cost of electricity by the hybrid plant is INR 6/kWh for plant capacities >5 MW.

Visual Communication in Think Tanks

In think tanks, visual communication happens at multiple levels and in various forms, for example, process diagrams, graphs, progress reports, and infographics. However, researchers face several challenges in incorporating such visual elements in their documents. For example, the researcher might find it difficult to strike a balance between text and visual content; the process might be time consuming because it has to be outsourced; the researcher might not be convinced of the design.

A 'concrete' idea for stubble burning

Burning the generated straw in a closed system like a cement kiln, where the exhaust gas adheres to pollution norms, can significantly curb the woes of stubble burning. Every kilogram of rice produced implies 0.7-1.4 kg of rice straw, which means 4-8 million tonnes of straw being burnt on the fields in Punjab and Haryana collectively. The straw can produce as much as 50-100 petajoules (PJ) of energy. This can be used in cement kilns to meet the thermal energy demand for producing cement.

Modeling of Solar and Biomass Hybrid Power Generation—a Techno-Economic Case Study

Solar power plants are expected to play a significant role in India’s power sector. The country plans to achieve an installed capacity of 100 GW by 2022. However, in a stand-alone mode, solar power plants are not able to deliver a consistent power supply, as per the demand requirement, to Electricity Supply Companies (ESCOMs). This is mainly because of the nature of intermittency associated with solar energy.

Developing a Comprehensive Emission Inventory for Bengaluru

CAPS is developing an emissions inventory for Bengaluru by estimating the emissions load from different sectors contributing to air pollution and analysing the spatio-temporal distribution of the emissions load. The emission inventory will estimate emissions from various sources in the airshed area of Bengaluru (60 km X 60 km).  

The study has the following key objectives:

Maintenance - An underrated piece in the solar energy puzzle

The maintenance aspect of solar installation is currently a shy topic and not adequately discussed. To make solar energy a success story, we must embrace its nature completely and support it the right way to make it a sustainable solution. Even a simple step such as cleaning the modules the right way could support a bigger idea of an effective clean energy solution.

Solar Energy Integration

This chapter covers the integrated analysis component of the program, which provided a critical resource to help define the optimal research agenda. This work includes assessing the solar resource across the various climate zones in India and a coupling of this to the technology roadmaps in India and the United States. The analysis was coupled with mapping optimal site selections for diverse applications of photovoltaics (PV) and concentrated solar power (CSP) from village power to national grid.
