Scientists at NTU in Singapore developed a process converting discarded shrimp shells into carbon-negative hydrogen fuel, aquaculture protein, and calcium carbonate. This lab-scale technology aims to reduce waste and offer cleaner alternatives to fossil-based energy and industrial materials, though commercial scaling faces efficiency and economic hurdles.
Scientists in Singapore have developed a process to convert shrimp shells and other organic waste into hydrogen fuel, protein for aquaculture feed, and calcium carbonate for construction. The technology, developed at Nanyang Technological University, aims to be carbon-negative by removing more CO2 than it produces, offering a dual solution for waste reduction and cleaner energy.
Delhi's new Electric Vehicle Policy 2026 includes provisions for hydrogen fuel-based vehicles within four years. The Delhi Transport Corporation will introduce two hydrogen-powered buses in collaboration with NTPC, aiming to reduce vehicular emissions.
China plans to reduce terminal hydrogen prices to below 25 yuan/kg by 2030, aiming for 100,000 fuel cell vehicles. Current prices exceed 35 yuan/kg. Key challenges include reducing green electricity costs for hydrogen production and improving storage density. The industry is transitioning towards commercialization.
