Power-to-Hydrogen and Hydrogen-to-X System Analysis of the techno-economic, legal and regulatory conditions: a new task of the IEA Hydrogen Implementing Agreement
Abstract
Energy systems are changing around the world due to a variety of factors:
- Increasing demand for energy in the world due to globalization and emerging countries;
- Increasing renewable share in the energy mix, especially in the electricity mix;
- Greenhouse gas constraints and CO$_2$ reduction in the energy sector;
- Local pollution constraints;
- Deregulation in the energy system, allowing new challengers to enter the market;
- Energy security constraints, reliable systems needed;
- Needs for decentralisation systems, and local production.
The balancing of the electricity grid is increasingly challenging as the installed renewable energy capacity is
increasing. Solutions like transmission super grid, smart grid and demand management, or back-up capacity
implementation could help overcoming this issue; but new measures that go beyond increasing transmission capacity
and flexible generation or consumption will have to be introduced to manage the grid as the level of renewable energy
sources is increased. Energy storage technologies, including hydrogen-electrolyser-fuel cell combinations will be a key
factor in this perspective.
