The complex path to biofuel sustainability

Until a few years ago, working on biofuels called for constant justification in the face of electric vehicles (EVs) taking over the world. Today, while there is no doubt that EV adoption has amplified over the years, there is growing awareness of the fact that no decarbonisation strategy is trade-off-free. For instance, for a transition to EVs, existing internal combustion engine (ICE) vehicles and the supporting infrastructure need to be replaced entirely, which is capital intensive.

Can Hydrogen hasten the utilisation of alternative fuel resources in the cement industry?

In 2021, Hanson — a subsidiary of Heidelberg Cement in the United Kingdom — substituted 100% of thermal energy with energy from alternative fuels in one of its cement kilns by using a mixture of hydrogen (39%), glycerine (49%), and meat and bone meal (MBM; 12%) instead of coal. This is the world’s first usage of 100% climate-neutral fuel and one of the first demonstrations of hydrogen-based technology in the cement kiln. Such adaptations, comprising a climate-neutral fuel blend, in the Indian cement industry remain elusive, even in 5% of the plants.

Breathing New Life into Wind Energy: How High-Potential States Can Revive the Sector

India’s wind capacity target for 2030 is 140 GW, and the current wind installation achieved until April 2023 is 42.8 GW. To achieve the remaining 98 GW, considerable growth rate and comprehensive efforts are needed in the coming years. India has a total wind energy potential of 695GW at 120 metres (National Institute of Wind Energy), which is on par with the solar energy potential of 748GW (National Institute of Solar Energy).

How India can rejuvenate its Waste-to-Energy sector

India generates an enormous amount of waste, including municipal solid waste (MSW), industrial waste, hazardous waste, and biological waste. According to the State of India's Environment 2023 report, MSW generation in India is estimated to be around 150,000 tonne per day (TPD). To harness the energy potential of this waste and reduce reliance on landfills, waste-to-energy (WTE) processes are being explored across India.

Climate resilience must be built into infrastructure and social and political systems

Any development programme can foster climate adaptation and mitigation benefits; it must also, however, feature self-reflection and system assessments. The renowned ecologist C.S. Holling, who brought resilient thinking to the forefront of socio-ecological studies, asserted that systems must evolve while they build resilience. If the baseline system itself is fundamentally unjust and unsustainable, then evolving to a new system is preferable to belatedly attempting to add resilience.

eARTh: Our planet, Our art, Our ideas

CSTEP launched the eARTh Initiative on 14 October at the Bangalore International Centre, bringing art to the heart of climate action. The event brought together scientists, artists, conservationists, and citizens to explore how art and science can meet to trigger a positive change for the planet. 

 

Employing a Systems Thinking Approach in Climate Risk Assessments

The world is witnessing the increasing impacts of climate change at an alarming rate. Wildfires, floods, cyclones, and heatwaves have become uncomfortably common today. Current research in climate sciences tells us that even if we were to completely stop producing greenhouse gases today, we would still face the detrimental impacts of climate change due to historical emissions. Additionally, the impacts of climate change are not felt in isolation.

Report Launch: Jharkand

The Consortium including CSTEP and the Centre for Environment and Energy Development (CEED) completed emission inventory studies for six cities in Jharkhand. The Jharkhand State Pollution Control Board (JSPCB), CEED, and CSTEP jointly released the emission inventory reports related to air pollution scenarios of six cities in Jharkhand on 10 April 2023.

India committed to achieving net-zero by 2070; new tech to mitigate climate change

Intergovernmental Panel on Climate Change's Sixth Assessment Report has, for the first time in the three-decade history of its reports, dedicated an entire chapter to innovation and technological development. The immense potential of new technologies for climate adaptation and mitigation is being recognised by policymakers and investors alike.
