Task 41: Data and Modelling
Task 41 is the successor to Task 38 (Power-To-Hydrogen and Hydrogen-To-X) and Task 30 (Global Hydrogen Systems Analysis). The Task has four subtasks, each contributing to the overall goal of providing updated parameters describing Hydrogen technologies, as well as to develop knowledge of how to model Hydrogen in the value chain.
The experts have two meetings per year.
The main objectives of this Task are to provide an updated and updatable long-lasting database on Hydrogen technologies allowing improved modelling, understanding and decision making. Additionally, the Task aims to establish a closer collaboration between the Hydrogen TCP and the ETSAP analysis community. The IEA is expected to be a major beneficiary of this Task.
Subtask a: “Data consolidation of parameters describing hydrogen technologies”
This Task complements Subtask b as it aims at establishing the data structure and the acquisition process supporting a sustainable database to fuel the relevant models for Hydrogen in the value chain. This Task is two-fold.
- It aims first at establishing a database and its underlying infrastructure. Such a database shall enable the techno-economic description of the different process steps of a supply chain as well as the market/end-use for hydrogen.
- It aims then at populating the database with up-to-date data sets and, in parallel, structuring a sustainable acquisition process. Such a process will rely on a structured methodology that will ensure the validation of data prior to its addition to the database.
The Scope will cover various hydrogen value chains focusing on generation/processing, storage, distribution and market/end-use. Both conventional (i.e. fossil fuels) and renewable sources will be covered. When applicable, data from task 30 and task 38 will be used, and if relevant, dialogue with other TCP tasks will be carried out.
Subtask b: “Develop knowledge of how to model Hydrogen in the value chain and improve current methods”.
The objective of this subtask is to obtain knowledge regarding the features of an ideal hydrogen modelling tool. This involves how to appropriately represent technologies and inter-sectoral connectivity in an optimal way. We want to study how various groups model hydrogen technologies. The main focus will be on TIMES models, but the aim is to include other model approaches as well. Advantages/disadvantages with various model approaches will be described. We want to answer what components of the “ideal” framework can realistically be included in TIMES (and possibly other model approaches). Issues to be discussed include temporal and spatial resolution, technologies and inter-sectoral connectivity and consumer behaviour. Model transparency and user-friendliness will be covered as well.
Subtask c: “Collaboration with analysts in IEA HQ Analytics and the ETSAP community”
The objective of this Subtask is that the modelling experts in ETSAP and in the Hydrogen TCP cooperate on the collection and handling of data, and to give guidelines on how to improve the modelling of hydrogen technologies. Today, the level of modelling detail for hydrogen technologies varies widely between different (TIMES) models, where most models contain a basic set of technologies. Only a few models consider more advanced technologies.
Subtask d: “Review reports from IEA”.
The objective of this Subtask is to review draft reports from IEA where the topic is related to hydrogen. Examples of such draft IEA reports include Energy Technology Perspectives and the World Energy Outlook.
