Renewable energy

Around 16% of the world’s energy consumption comes from renewable resources such as biomass, hydro, wind, solar and geothermal. Renewable sources of energy have been the driver of much of the growth in the global clean energy sector for the past 25 years, and today at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply.

Ramboll is a leading engineering consultancy in AD and biogas, and has been involved with AD and biogas projects for over a decade. Our work includes establishing major modern facilities dealing with a variety of feedstocks,  gas production for direct energy generation, as well as compression and fuel supply.


Ramboll is one of the most experienced engineering consultancies in the field of biomass, with a track record of delivering over 60 biomass power, heat and CHP facilities, using a full spectrum of fuel types.  We specialise in reliable and high efficiency facilities, with some of the resulting plants using advanced energy recovery systems that allow them to even claim energy efficiency rates of more than 100 percent.

Hydro power

Over the years Ramboll has become a well-known hydro power consultant, particularly on the Swedish market. Ramboll works to innovate and streamline hydro plants. By utilising the latest technology and optimisation solutions, we optimise the power stations to raise the efficiency of existing units. We design, monitor and assure the quality of investments, both retrofits and new hydro power plants.

Our project references include the establishment of 15 of the largest solar heating plants in Scandinavia, including the world's largest plant, which is located in Marstal in Denmark. Over the last four years we have also been involved in photovoltaic solar energy projects with electrical outputs of up to 46,300 kWh annually.

Tidal & wave

Ramboll has a long track record of inventive and innovative design in the marine environment and for taking advantage of the repeatability of structure for the renewable sector, including tidal & wave installations. Ramboll is currently working on a 10MW tidal test array from concept study to detailed design for both foundation design and installation methodology.

Geothermal energy

Ramboll has over 10 years of experience within the field of geothermal energy. This includes areas such as seismic, geological and geophysical studies and investigations including modeling and reservoir hydraulic calculations and evaluation. Furthermore Ramboll has specific knowledge within the field of well site layout/infrastructure and permissions, and follow up on operation and maintenance.
