Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050.

New catalyst synthesis method for solar water splitting to produce hydrogen

Green Car Congress

A research team led by Daegu Gyeongbuk Institute Of Science And Technology (DGIST) Professor Jong-Sung Yu in Korea, with colleagues at UC Berkeley and Xi’an Jiaotong University in China, has successfully developed a new catalyst synthesis method that can efficiently decompose water into oxygen and hydrogen using solar light.

New protocol to enhance photosynthetic production of hydrogen from green algae

Green Car Congress

A research group from the University of Turku, Finland, has developed a new protocol to deliver sustained hydrogen photoproduction in green algae under a train of strong white light pulses interrupted by longer dark phases. This led to techniques such as sulfur-deprivation to extend hydrogen production.

Monash “artificial photosynthesis” system achieves in excess of 22% efficiency for production of hydrogen from water

Green Car Congress

A team at Monash University (Australia) has developed an “artificial photosynthesis” system that delivers the highest efficiency reported to date—in excess of 22%—for the solar-driven conversion of water to hydrogen. A paper on the researchers’s work is published in the RSC journal Energy & Environmental Science.

Lehigh team uses single-enzyme biomineralization process to create photocatalyst for H2 production

Green Car Congress

Engineers at Lehigh University are the first to utilize a single enzyme biomineralization process to create a quantum confined CdS/reduced graphene oxide (CdS/rGO) catalyst that uses the energy of captured sunlight to split water molecules to produce hydrogen. The synthesis process—catalyzed by the single enzyme cystathionine ?-lyase
