Operating Agents: Dr. Luis Correas, Fundacio n Para el Desarollo Tecnologas del Hidrogeno in Aragon (firstname.lastname@example.org) and Mr. Fernando Carpintero, Gamesa Energa
Term: Task 24 was approved in 2006 with a four year term of operation.
Purpose and Objectives:
Background: There is broad interest in hydrogen production by means of renewable energy sources, as hydrogen is expected to be one of the main energy carriers in the near future. From the perspective of technical and economic feasibility, water electrolysis by wind energy ranks high among renewable energy sources for hydrogen production as a competitor to fossil fuel. However, water electrolysis technologies were not conceived for the variable input conditions inherent to wind resources. Therefore, the current state of the art must be upgraded, largely to avoid redundant electronics.
The fully integrated wind and hydrogen application connects wind technology with various hydrogen related technologies such as electrolyzers (for production), hydrogen to electricity converters (for utilization) and storage systems. If wind farms can be coupled to energy storage systems, wind energy will become available to offset the growth in network capacity. Furthermore, wind farms would become multi-purpose, decentralized producers of either electricity or hydrogen for fuel when the automotive industry enters mass production of hydrogen-fuelled vehicles. Off-grid systems relying solely on renewable energy sources constitute an important niche market.
Description: Task 24 has four subtasks, which are listed and described below:
Subtask A - State of the Art
Subtask A will conduct an in-depth review of the current state of the art in wind turbines, electrolysers, and intermediate equipment, as well as a survey of market and electrical system regulation.
Subtask B - Needed Improvements & System Integration Technology Development on Main Equipment and System Integration Concepts
This subtask is focused on two main components for hydrogen production?the wind turbine and the electrolyzer, including the intermediate components. The subtask goal is to develop proper specifications. To do so, it must consider the following issues:
Subtask C - Business Concept Development
Subtask C will deal with the following issues:
Subtask D: Applications, Emphasis on Wind Energy ManagementThis subtask will consider near-term applications for the wind-generated hydrogen with a special focus on one of the main application specified in Subtask C, wind energy management within the wind and hydrogen full integration concept. An analysis similar to those undertaken in tasks A to C will be performed for relevant components not previously taken into account. These components include hydrogen to electricity converters such as fuel cells, internal combustion engines and gas turbines.
The current task participant list includes:
The kickoff meeting for this task was in April, 2007 in Walqa Technology Park, Huesca, Spain. The work plan for each subtask is on schedule.
