IRENA sees renewable hydrogen at least cost-possible within decade

Green Car Congress

Hydrogen produced with renewable electricity could compete on costs with fossil fuel alternatives by 2030, according to a new report from the International Renewable Energy Agency (IRENA). The report— Green Hydrogen Cost Reduction: scaling up electrolyzers to meet the 1.5

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

The results from this study suggested a cost of hydrogen as low as ¥17 to ¥27/Nm 3 (US$0.16 - $0.25) using a combination of technologies and the achievement of ambitious individual cost targets for batteries, PV, and electrolyzers. This approximately converts to US$1.92 to US$3.00/kg Credit: NIMS. 2018.11.119 ).

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen’s AI-enabled concentrated solar energy system is designed to create carbon-free steam, electricity, and heat from abundant and renewable sunlight. When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Consequently they maintain peak discharge power for less than an hour before they are drained, and are therefore ill-suited to store intermittent renewables.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Methane derived from CO 2 and renewable H 2 sources is an attractive fuel, and it has great potential as a renewable hydrogen carrier as an environmentally responsible carbon capture and utilization approach. The authors’ assessment identified further cost savings, in that CO 2 captured by EEMPA can be converted to methane on site.

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

A team led by Dr. Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Jingshan Luo, post-doctoral researcher, explains how. Credit: EPFL.
