Ambition and progress beyond state of the art 


H2HEAT will contribute substantially to advancing the concept of green H2 for heating (and O2) both in terms of “idea to application” and “lab to market“.

Electrolyser Advances

Alkaline based electrolysers are more mature when compared with proton (PEM) or anion (AEM) exchange membrane electrolysers. However, they typically employ expensive electrode precious metal materials resulting in cost inefficiencies and likely increasing future costs.


Stargate Hydrogen is developing advanced alkaline electrolysers based on nanoceramic active materials. The use of novel materials allows Stargate to achieve performance that is on par with widely used precious metal-based electrolysers (both PEM and precious metal-based alkaline), yet without the use of precious metals. It will be demonstrated that the materials that Stargate utilizes in its novel cells and stacks can achieve electric power consumption of 45 kWh/kg H2 at the high-efficiency operating point. Quantitatively, Stargate electrodes will demonstrate electrolysis current ≥50x higher than for IrO2 electrodes per EUR invested.


H2-CHP ADVANCES

There are currently no 100% H2-CHP installations in most European countries. There are none in the Canary Islands. An alternative are 100% H2 boilers, but they too at R&I stage. EU funded BIG HIT combined 12 5kW domestic H2 boilers to heat 2 schools. Progress is being made on blend-certified condensing boilers (typically 20% H2 with natural gas) which will eventually be replaced by pure hydrogen. Another route being pursued is the hydrogen hybrid heating system that combines a H2 boiler and heat pump e.g. trials at Port of Milford Haven.

The H2HEAT 100% H2-CHP developed by partner 2G will be the first real commercial scale H2-CHP.

H2-CHP by partner 2G

The key innovations include:

  • It is the first CHP to work with H2 stably, with high efficiency.
  • Due to the fact that hydrogen has a very high detonation capacity, the mixture will take place inside the combustion chamber, so the gas will be injected through the Hoebiger injection valve, while the air will be compressed with the turbocharger. The process has to be very precise, therefore the injection valves will be electronically correlated with the cylinder head valves.

  • It is essential to be able to control the production of electricity, and enable it quickly adapt to the consumer requirements.  The 2G H2-CHP will be able to start, stop and work at part load. It will to be able to work in island mode and achieve the maximum load possible in the minimum time.
  • The CHP from 2G can operate with varying levels of gas purity compared to fuel cells which require pure H2.

The H2HEAT project is grabbing attention by showcasing creative ways to harness renewable energy and transform it into renewable energy carriers in the fight for a better, more sustainable future. With a focus on cost-effectiveness, energy efficiency, and environmental sustainability, this revolutionary effort aims to revolutionise the energy landscape.

Green Hydrogen Production

H2HEAT will showcase the production of hydrogen (H2) through the conversion of renewable energy (RE) supplied by Esteyco Offshore Wind (OSW). This transformation will be achieved using cutting-edge technology, particularly the Stargate electrolyser installed in a dedicated H2 facility. Key Performance Indicators (KPIs) related to wind energy efficiencies, cabling infrastructure, energy loss reduction, and H2 production will be rigorously tested in Work Package 4 (WP4). The integration of a sophisticated control system developed by NeoDyne will ensure maximum efficiency by accounting for RE variability and demand/supply balancing.

Sustainable Heating Solution

In an effort to reduce carbon emissions and enhance energy efficiency, H2HEAT will demonstrate the use of hydrogen (H2) for heating applications at the CHIUMI hospital. This hospital currently consumes a substantial 5000MW/year for heating purposes. By substituting traditional heating fuels with H2 from a combined Heat and Power (CHP) system or Heat Pump, the hospital aims to achieve up to 90% reduction in its heating fuel consumption. WP4 will evaluate the combustion efficiency and other key specifications.

Environmental Sustainability

One of the primary goals of the H2HEAT project is to achieve near-zero carbon emissions throughout the end-to-end green H2 heating process. Drawing on the extensive experience of our partner organizations in implementing green energy solutions, we are committed to adhering to European Environmental and Social standards and taxonomy principles. Environmental and Social Impact Assessments (ESIA) will be conducted, along with comprehensive Life Cycle Analysis.

WP1 will closely monitor the entire project, supply chains, and value chains, focusing on pollution prevention, biodiversity, climate change, and ecosystems. Copernicus data and products will be leveraged for in-depth environmental impact analysis.

Socioeconomic Sustainability

H2HEAT recognizes the importance of socioeconomic sustainability in its heating supply and value chains. This will be achieved through a Quadruple Helix approach in Objective 5 (WP7), emphasizing public engagement, community involvement, and responsible research and innovation (RRI) principles. Collaboration with the local community and Gran Canaria authorities will be initiated at an early stage. The project will also prioritize the use of local materials, services, and labor whenever possible. Education and knowledge transfer activities will ensure that the Las Palmas and wider Gran Canaria community is informed, educated, and actively participates in the Green Energy Valley concept and H2HEAT.

Achieving Technology Readiness Level 7

The H2HEAT project aims to achieve Technology Readiness Level 7 (TRL7) by the end of the project duration. This milestone will be reached through the comprehensive demonstration of the H2HEAT technology in WP4 within Gran Canaria’s operational environment. The project will undergo rigorous monitoring for a 24-month period, ensuring that all objectives are met and that the technology is ready for real-world applications. WP3 will develop a detailed test strategy, covering Factory, Site, and Demonstration Acceptance testing.

Cross-cutting Priorities: Artificial Intelligence and Digital Agenda

H2HEAT will lead the way in designing and implementing a full control system, including a smart Energy Management System (EMS), Demand Side Management (DSM) system, and Supervisory Control and Data Acquisition (SCADA) system. This integrated approach will facilitate demand response, modeling, and forecasting, ensuring energy efficiency in the face of variable energy supply. The system will also enable digital monitoring, analysis, and reporting during the demonstration phase, positioning H2HEAT at the forefront of the digital agenda.

The H2HEAT project represents a significant step toward a sustainable and eco-friendly future, where renewable energy is harnessed efficiently, and innovative solutions are implemented to address our heating needs. Stay tuned for updates as H2HEAT paves the way for a cleaner, greener energy landscape.

Mitigating Risks through Measures

Hydrogen Sensors and Leak Detection

Sensors promptly detect leaks in homes and industries, triggering alarms or system shutdowns if hydrogen levels become unsafe.

Purpose: Hydrogen sensors are devices designed to monitor the concentration of hydrogen gas in the air. They play a critical role in detecting leaks promptly to prevent potential hazards.

Hydrogen sensors typically employ various detection methods, such as semiconductor sensors, which change their electrical conductivity in the presence of hydrogen gas. When hydrogen levels rise beyond safe limits, these sensors trigger alarms or activate safety protocols.


In residential and industrial settings, hydrogen sensors are installed in areas where hydrogen is stored or used. If a leak occurs, the sensor detects the increase in hydrogen concentration and sends signals to warning systems or control units to initiate safety measures. These measures can include activating ventilation systems, shutting down equipment, or alerting personnel.

Storage Safety

Purpose: Ensuring safe hydrogen storage is crucial to prevent leaks, explosions, or accidents.

Advancements in Materials: Innovative materials and design techniques are employed to create robust hydrogen storage systems. These materials are selected for their compatibility with hydrogen and their ability to withstand high-pressure conditions.

Types of Storage: Hydrogen can be stored in various forms, including compressed gas, liquefied hydrogen, and solid-state storage materials. Each type comes with its own safety considerations, which are addressed through materials and engineering solutions.

Safety Features: Storage systems are equipped with safety features such as pressure relief valves and double-walled containers to minimize the risk of leaks or ruptures.

Application: Secure hydrogen storage is essential in industrial facilities, where large quantities of hydrogen are often stored, as well as in residential settings where hydrogen-powered heating systems are becoming more prevalent.

Training and Education

Proper training and education ensure that personnel and users understand the properties of hydrogen, safe handling procedures, and appropriate responses in case of emergencies.

Training programs cover topics such as the flammability and behavior of hydrogen gas, safe storage and transportation practices, and protocols for responding to leaks or accidents.

Education is a fundamental aspect of hydrogen safety, as informed individuals are better equipped to prevent accidents and respond effectively if a safety issue arises.

Training is provided to employees working with hydrogen in industrial settings and individuals using hydrogen-powered systems in residential applications.

Research and Development (R&D):

Ongoing R&D efforts focus on advancing hydrogen system safety through various means, including materials development and the creation of advanced sensors.

R&D activities aim to develop materials that are more resistant to hydrogen embrittlement and degradation, enhancing the integrity of storage and transport systems.

Advanced sensors are designed to improve the accuracy and speed of hydrogen leak detection, enabling quicker response times.
