HyperSolar Inc., developer of renewable hydrogen (H2) technology using sunlight and water, has demonstrated significant cost reductions to green H2 by replacing expensive platinum material compounds with new, low-cost ruthenium/carbon/nitrogen-based H2 evolution catalyst.
With help from Professor Jong-Beom Baek and his research group at Ulsan National Institute of Science and Technology (UNIST) based in South Korea, HyperSolar developed a new catalyst that is 20x cheaper than the current platinum one and equally functional.
HyperSolar integrated this ruthenium-based catalyst for H2 evolution with its proprietary low-cost catalyst for oxygen evolution onto a triple junction silicon solar cell. The HyperSolar device clearly demonstrated the production of copious amounts of H2 and oxygen bubbles under water within a minute of exposure to simulated sunlight.
