Our services

Innovative projects

  • We have a strong background in engineering consultancy, often applied to large R&D projects funded at e.g. EU level. Such tradition allows us to be constantly aligned with state-of-the-art topics, engineering solutions and methods. 

  • Our experience ranges from technical support to project management. As an example, we have been directly involved in multiple H2020 projects, with a total amount of funding exceeding €20m.

  • In research projects, Yavin Four Consultants usually gets involved at the project’s inception – supporting the proposal creation process. Typically, we are partners in the project – meaning we believe in the project and will stay involved until its completion. 

Engineering design

  • At our core, we are engineers and designers. Combined, such characteristics have allowed us to be involved in flagship projects in our sector – and we are constantly eager for opportunities to apply our skillset in novel projects.

  • We can be involved at any design stage – from concept to detailed level. 

  • Our engineering expertise is primarily linked to technology design - but it is also related to project development. Commercial and strategic topics, such as site assessments and LCOE modelling, are examples of frequent projects. 

Strategic advice

  • Throughout the years, we have specialised in providing strategic advice to a range of clients (national governments, investors, project and technology developers) on both technical and commercial topics.

  • Our 100% independent nature allows us to advise our clients in an impartial way, whether in a due diligence advisory capacity and / or in road mapping / strategic positioning exercises.
