Storage solutions that can hold energy for days and weeks are urgently needed the world over The arithmetic of the energy transition is increasingly clear. Solar and wind can now generate electricity at prices that rival, and even undercut, fossil fuels. “The business case for renewables is now stronger than ever,” as the International Renewable Energy Agency  noted  this year.   Yet grids across the world are still  curtailing large volumes  of clean power because they have

Industrial decarbonisation demands more than renewable energy installations. It requires fundamental improvements in how factories, vehicles, and buildings use energy. Among the least celebrated yet highly effective interventions is thermal insulation — a technology where materials science innovations could deliver outsize climate benefits.   Energy efficiency  remains an overlooked  but critical component of climate action. The International Energy Agency  estimates  that im

India's ambitious push into green hydrogen production is creating substantial opportunities for domestic deep-tech startups, with companies like Newtrace demonstrating how innovative engineering can address cost barriers that have limited clean hydrogen adoption.   The government's National Green Hydrogen Mission, launched in January 2023 with close to Rs. 20,000 crore in funding,  aims to produce  five million tonnes annually by 2030. Recent policy developments have accelera

Optimism and investment are rising, more breakthroughs are anticipated, and a commercial reactor is expected as early as the next 10-15 years. It’s time for Indian startups, too, to step up.
