R&D Divisions

Assured biomass supply is most crucial for the success of any commercial bioenergy plant. Recognizing the importance of biomass resource management, the division is working on assessment of surplus biomass from agricultural activity based on an evaluation study conducted by ASCI on behest of MNRE, Govt of India in 2017-18. Using this report as the basis, further studies would be carried out using advanced data analytics for predicting the availability of biomass in the country and estimating the energy potential from surplus biomass. The division also works on life cycle assessment of different bioenergy systems.

In addition, the division is also working towards popularizing efficient biomass technologies by undertaking technology demonstration programs. In the first instance biomass cookstoves/combustors are planned to be demonstrated in the state of Punjab.

The priority topics of the division are:

Biomass characterization and generation of database
Technology demonstration and monitoring of improved cookstoves/combustors at selected sites for domestic, institutional and industrial end uses in the state of Punjab (jointly with Jain University).
Biomass Mapping using GIS Techniques
Biomass assessment using advanced analytics
Biomass conversion routes and pre-treatment techniques
Biomass Supply Chain Management modeling studies
Sustainability evaluation of bioenergy Systems

Scientists associated with the division

Dr Ashish Bohre. Scientist-D with expertise in catalytic conversion of lignocellulosic biomass into high-value chemicals and biofuels, catalysis and process technology.
Dr Vandit Vijay, Scientist-C with expertise in biogas and biodiesel production from different feedstocks and their utilization in IC engines for energy applications, biomass resource assessment, and carbon neutrality approaches including biochar.

The division is well equipped with necessary instrumentation and equipment to develop technologies based on the thermochemical conversion processes. The division has an established test facility for biomass cookstoves, where performance of cookstoves is carried out as per BIS standards. It has also taken up development and testing of biomass cookstoves of a range of power levels to suit different types of end requirements. It also houses a 10 kWe biomass gasifier with a diesel engine for testing of different feedstocks and also serves as a demonstration and training system.

With the recent signing of MoU with Jain university, the development and testing of biomass cookstoves and combustors is going to gain huge impetus and pave the way for collaborative work with them. The division envisages to take up both experimental and simulation work in near term with thrust areas as follows:

Modernization of biomass Cookstove Testing & Certification Centre and seeking NABL accreditation
Development of efficient, durable and affordable Improved Biomass Cookstoves on par with LPG Stove in terms of performance
Integration of Solar Energy and Bioenergy Systems for Performance Enhancement and Applications e.g. biomass-solar hybrid dryer for agricultural products.
R&D on torrefaction technology including energy recovery from MSW and hydrogen generation.
Biomass heat for integration with vapor absorption/adsorption chiller for cold storage application.
Densified biomass - paddy based pellets/briquettes, addressing issue of alkali and chlorine – power plants

The division is also executing three projects relating to biomass pellets and briquettes that are sponsored by CPRI, Bangalore and one project on use of biomass briquettes in gasifier that is sponsored by MNRE. For more details see page on on-going projects.

The division is fostering a multidisciplinary approach in order to develop a biorefinery concept and consolidated bioprocessing for the production of sustainable biofuels such as biogas, biohydrogen, bio-ethanol and bio-butanol from lignocellulosic biomass. The focus is on biological conversion of biomass, exploration and strain development of industrially important microorganisms, development of novel bio-catalysis (extremozymes) to degrade the biomass by implementing the advanced genomics, proteomics and molecular techniques. The division has necessary infrastructure to develop technologies based on biochemical conversion processes. Research Priorities of the division are as follows:

Process development for bioethanol, biobutanol and biohydrogen production from lignocellulosic biomass
Pilot scale studies and technology dissemination for biogas, bioethanol and biohydrogen production
Biogas upgradation to BioCNG
Value added products apart from liquid or gaseous fuels

The division is working on development of sustainable materials for electrochemical energy related applications. Lignocellulosic biomass is ideally suited as a base feedstock for the manufacture of such long lasting materials. The objective of the division is to generate cheap and sustainable materials from biomass, leading to improved performances in electrochemical applications. The division is therefore establishing a complete work station for fuel-cell system development work including membrane development, characterization, testing and performance improvement. The research priorities include:

Development of new composite membranes with varying inorganic fillers
