The rise of green hydrogen-as-a-service: How AI digital twins are powering the net-zero future
As green hydrogen scales from pilot projects to industrial supply chains, the organizations that pair AI-powered digital twins with green hydrogen-as-a-service (GHaaS) commercial structures will be best positioned to deliver clean hydrogen at competitive cost and speed.
Perovskite–silicon tandem solar cells using zinc-doped tin oxide achieve comparable performance to indium tin oxide counterparts
Fraunhofer ISE-led researchers demonstrated zinc-doped tin oxide (ZTO) as an indium-free alternative to indium tin oxide (ITO) for recombination layers in fully textured perovskite–silicon tandem solar cells. ZTO delivers comparable device efficiencies of 27–28% under current-matching conditions, offering a scalable, indium-free pathway for high-performance tandem photovoltaics without efficiency loss.
From LPG uncertainty to energy resilience: Why Indian industry is turning to cleaner, more dependable fuel systems
India’s industrial sector is entering a pivotal phase in its energy transition. What was once a routine fuel procurement decision is now becoming a strategic imperative. Rising LPG costs, supply unpredictability, and increasing operational risks are prompting businesses to rethink how they power their operations — not just for efficiency, but for resilience.
