Project description

Green hydrogen produced with clean electricity is seen as one of the critical enablers for the global transition to sustainable energy and net-zero emissions economies. Consequently, a significant increase in the utilisation of electrolysis technologies is predicted.

Recently, several electrolyser projects in many countries have been announced and huge growth in the number of projects is expected. Additionally, the size of the projects is expected to grow significantly. With the increased size of the electrolysers the power electronics used in them have become one of the key elements for affordable clean hydrogen production. With large plant sizes in the range of 100 MVA and up, the interconnection of the electrical power converter with the power grid becomes essential. Furthermore, power electronics enabling high efficiency and low capital cost are required.

In ComElCo power electronics converters for electrolyzers with improved efficiency, low cost, and provisions for grid services are developed.

The green fuel value chain and cross-cutting themes

Resource procurement (Input)
Identification, sourcing, and supply of biomass, CO₂, green electricity, or waste materials (feedstock) used as input for fuel production.
Fuel production
Processes that transform the basic energy resources into primary energy carriers (e.g. hydrogen).
Refining and upgrading
Processes that purify, enhance or synthesize fuels/hydrogen to meet specific quality and performance standards.
Storage
Technologies and systems for containing larger quantities of fuels (methanol, ammonia, hydrogen, SAF) over time.
Transport
Logistics and infrastructure for moving fuels from production to consumption sites, covering pipelines, trucks, ships, etc.
Distribution
End-point delivery for supplying fuels to users (e.g. fuelling stations, industrial supply lines, on-site storage).
Utilisation
Application of the fuels in end-use sectors such as heavy transport, aviation, shipping, and power generation in industry. The end-user is responsible for sourcing of energy/fuels, as well as new technologies and assets capable of utilising these, often with the purpose of reducing GHG emissions and environmental impact. Furthermore, end-users are also responsible for meeting new regulatory requirements and handling all technical and commercial risks related to the application of new and more expensive energy, following the energy transition. Utilisation includes extensive field testing of new technologies and fuels to overcome technical challenges and test production and supply chain infrastructure.
Post-treatment and recycling
Handling of byproducts, residues or emissions, and processes for material recovery or environmental management.
Safety and standardisation
Development and application of safety protocols, technical standards and certifications to ensure secure handling and interoperability.
Systems integration / sector coupling
Linking fuel production and use with other energy systems and sectors (e.g. power-to-x, grid balancing, industrial symbiosis) to optimise efficiency and resilience. Primarily an analytical focus.
Community work and stakeholder involvement
Engagement of local actors, citizens and industry stakeholders to support implementation, acceptability and social sustainability.
Structural frameworks, regulation, and markets
Analysis, development and test of policy, regulatory structures, incentive mechanisms, and market models to enable deployment and scaling.
