Renewable hydrogen production

Furthermore, two technology-driven scenarios have been developed. In the first scenario, it is assumed that renewable hydrogen production must have a share of at least 50% from 2020 onwards ( REN ). In the second scenario, CCS technologies are additionally available ( REN-CCS ). 

Based on the framework of economic development, energy prices, hydrogen car penetration and the structure of renewable hydrogen production described in the previous sections, the hydrogen car s high-penetration scenario of HyWays is simulated with the ASTRA model and the results are compared with the BAU scenario.

Renewable electrolysis can help overcome one of the key barriers to realizing a hydrogen based economy by replacing the carbon intensive one that exists today. There is an excellent opportunity for research in renewable hydrogen production both in terms of understanding the operation of the electrolyzer under variable sources and optimizing, in terms of efficiency, cost, and robustness, the link between a renewable source and electrolyzer stack.

The HYDROSOL process represents the world s first closed, solar-thermochemical cycle in operation that is capable of continuous, pure renewable hydrogen production. It is expected that deployment of the HYDROSOL process will proceed with the ongoing cotnmercialization of solar thermal power plants. 

Distributed production of hydrogen from natural gas is another example of a near term solution that helps reduce pollution, while building the infrastructure for renewable hydrogen production methods that are still in development. 

A collaboration of the National Renewable Energy Laboratory and the University of California at Berkeley unveiled an experimental renewable hydrogen-production technique based on the action of green algae.
