What is hydrogen storage system well-to-wheels (WTW) energy analysis?

Energy Analysis: Coordinate hydrogen storage system well-to-wheels (WTW) energy analysis to evaluate off-board energy impacts with a focus on storage system parameters, vehicle performance, and refueling interface sensitivities.

Can electricity and heat storage help maintain hydrogen production and nominal operating temperatures?

Furthermore, as system capacity factor is often key to technological and economic feasibility, it would be promising to investigate the integration with electricity and heat storage technologies to maintain hydrogen production and nominal operating temperatures through periods of fluctuating or low DNI, or to enable 24-hour operation.

How does a solar energy system work?

The system utilizes a 6.8kW PV array and a 5kW electrolyzer powered by surplus solar power to produce hydrogen, which is then stored in a hydrogen tank via a compressor. In periods of high energy demand, when PV generation is not sufficient, the green fuel is used to produce electricity via a 1.24kW fuel cell system.

Can a solar hydrogen production plant co-generation a kilowatt-scale pilot plant?

Solar hydrogen production devices have demonstrated promising performance at the lab scale, but there are few large-scale on-sun demonstrations. Here the authors present a thermally integrated kilowatt-scale pilot plant, tested under real-world conditions, for the co-generation of hydrogen and heat.

Can a thermally integrated photoelectrochemical device co-generation hydrogen and heat?

Here we present the successful scaling of a thermally integrated photoelectrochemical device—utilizing concentrated solar irradiation—to a kW-scale pilot plant capable of co-generation of hydrogen and heat. A solar-to-hydrogen device-level efficiency of greater than 20% at an H2 production rate of >2.0 kW (>0.8 g min−1) is achieved.

Can solar irradiation be used for co-generation of hydrogen and heat?

Here we present the successful scaling of a thermally integrated photoelectrochemical device—utilizing concentrated solar irradiation—to a kW-scale pilot plant capable of co-generation of hydrogen and heat. A solar-to-hydrogen device-level efficiency of greater than 20% at an H 2 production rate of >2.0 kW (>0.8 g min −1) is achieved.
