Special Issue Information

Dear Colleagues,

Innovations in hybrid renewable energy technologies are a response to the challenges of climate change, energy costs, energy security and the need to create sustainable societies. Renewable energy is a constantly evolving sector, and one that will play a key role in shaping the future of energy. Progress and research enable the use of PV modules or heat pumps in various atmospheric conditions and on various scales. Trends in wind energy also indicate the dynamic growth of this sector: wind turbines have become more efficient and economical, and innovative offshore projects are expanding the potential of wind farms into deep sea areas. Modern hybrid technologies combining various sources of renewable energy enable the optimal use of these resources depending on weather conditions and energy needs.

We are seeing the integration of energy systems in our homes, for instance through the electrification of heating systems and electromobility, using V2G technology. It is becoming increasingly necessary to implement energy storage technology based on classic warehouses and hydrogen techniques.

The aim of this Special Issue is to collect the latest interesting and original research that demonstrates the energy, environmental, economic and social benefits resulting from the use of integrated renewable energy systems in residential buildings and industry. Taking into account the need to apply RES systems in systems subject to thermal modernization, it is also necessary to integrate RES systems not only with each other, but also with classic installations based on fossil sources in the transition period.

Manuscripts presenting research, case studies as well as reviews exploring the state of the art are welcome in this Special Issue. Its scope covers (but is not limited to) the following topics:

  • Hybrid energy systems;
  • Hydrogen systems;
  • Home and industry heat pumps with innovative lower heat sources;
  • Biomass and biogas technology;
  • Wind and water energy technology;
  • Photovoltaic and solar installations;
  • Energy management in buildings, homes and industry;
  • Electromobility integrated with renewable energy systems.

The above list is not exhaustive, and, in any case, works on areas not listed, but interesting for the Special Issue, are invited.

Green hydrogen is crucial for achieving climate neutrality and replacing fossil fuels in processes that are hard to electrify. Wind farms producing electricity and hydrogen can help mitigate stress on electricity grids and enable new markets for operators. While optimizing wind farms for electricity production is well-established, optimizing combined wind–hydrogen systems is a relatively new research field. This study examines the potential profit of wind–hydrogen systems by conducting a case study of an onshore wind farm near the North Sea. Varying turbine types from high wind-speed turbines (with high annual energy production) to low wind-speed turbines (with high full-load hours) are examined. Findings indicate that in a combined hydrogen system, the low wind-speed turbines, which are sub-optimal for mere electricity production, yield lower levelized costs of hydrogen at a higher hydrogen production. Although high wind-speed turbines generate higher profits under current market conditions, at high hydrogen prices and low electricity prices, low wind-speed turbines can yield higher total profit at this site. Therefore, an integrated optimization approach of wind–hydrogen systems can, in certain cases, lead to better results compared to an isolated, sequential optimization of each individual system.
