Thermoelectric Material Inverse Perovskites Generate Power
January 17, 2024 | Leave a Comment
Tokyo Institute of Technology scientists report in a new study environmentally benign inverse-perovskites with high energy conversion efficiency have potential for practical application as thermoelectric materials (TEMs). The recent study published in Advanced Science, the researchers presented “inverse”-perovskite-based high ZT TEMs with the chemical formula Ba3BO, where B refers to silicon (Si) and germanium (Ge). […]

Thermochemical Hydrogen Idea Harnesses Solar To Split Water
October 17, 2023 | Leave a Comment
Massachusetts Institute of Technology engineers have designed a system that can efficiently produce ‘solar thermochemical hydrogen.’ It harnesses the sun’s heat to split water and generate hydrogen – a clean fuel that emits no greenhouse gas emissions. In a study appearing in Solar Energy Journal, the engineers lay out the conceptual design for a system […]

Research Shows A New Thermoelectric Twice As Productive
September 28, 2023 | Leave a Comment
Researchers at the Vienna University of Technology discovered excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy. The researchers have published their results in the journal Science Advances. Thermoelectrics enable the direct conversion of heat into electrical energy – and vice versa. This makes them interesting for […]
