They show that concentrated GI as a large urban park, with partial use of reflective pavements, are effective in reducing temperatures at much lower costs compared to other configurations.

Using Computational Fluid Dynamics, they numerically model heat flows in hypothetical urban blocks under the meteorological conditions of Ahmedabad.

The authors study different configurations of GI and reflective pavement combinations to minimise initial and maintenance costs while offering effective cooling.

UHI can be combated by Green Infrastructure (GI), such as street tree cover and urban parks, and reflective pavements, which can reflect solar radiation and absorb less heat.

Metropolitan areas experience much warmer temperatures than their adjacent rural areas, in a phenomenon known as the Urban Heat Island (UHI) effect.

Cellegant Energy Systems and ESRL are working on projects for the Defence Research and Development Organisation (DRDO) and have secured grants from NIDHI PRAYAS and the Government of Gujarat.

The indigenous development of these technologies by ESRL and Cellegant can significantly reduce dependencies on exports in the defence and energy sectors, while being sustainable and contributing to India’s net-zero commitments.

Their advancements in fuel cell technology can multiply the range of UAVs and drones to hours, making them a strong contender to be used in defence and surveillance applications.

This expands the accessibility of hydrogen in remote areas where compressed hydrogen is not available, while also significantly mitigating the safety challenges with hydrogen.

Compact and lightweight on-board hydrogen generators can cut the weight of hydrogen carriage by half relative to compressed hydrogen storage, according to Prof Bhargav.

In addition to compressed hydrogen, the lab and startup are developing systems that use solid, liquid or gaseous hydrogen-carriers with on-board hydrogen generation.

In addition, these systems have been tested to work efficiently in different climatic conditions and temperatures, breaking ground in high-altitude UAV applications.

Their recent innovations in these subsystems can drastically improve system efficiency while reducing their weight and volume, which is extremely important for aerospace and marine systems.

The laboratory facility is equipped to test hydrogen fuel cell power packs and their subsystems, such as fuel and oxidant supply, thermal management and humidity management, which are essential for the efficient functioning of fuel cells.

This collaboration has made strides in hydrogen fuel cell technology, developing power packs and safe energy carriers for Unmanned Aerial Vehicles (UAVs) and other niche applications.

Cellegant Energy Systems, an IITGN startup founded by Prof Bhargav, which is currently incubated at the IIEC takes innovations in the laboratory to market.

“Our lab and startup focus on designing and building next-generation ultra-high efficiency hydrogen fuel cell systems that will power aerospace, marine and terrestrial mobility platforms,” says Prof Atul Bhargav, who leads the Energy Systems Research Laboratory (ESRL) at IITGN.
