Overall, Denmark’s offshore wind resources provide good conditions for the production of green hydrogen, which require large amounts of green electricity.
This white paper provides a brief overview of the Danish hydrogen sector, upcoming projects and Danish capabilities.

Solution Provider: Siemens Gamesa
The Brande Hydrogen Project, built by Siemens Gamesa, is pioneering a solution where a 3MW wind turbine is directly connected to an electrolyser without a grid connection.
In addition to providing 50-70 taxis with 100% green fuel daily, this solution demonstrates that green hydrogen can be produced cost-efficiently, reliably, and effectively from wind power.

With plans on establishing the world’s first two energy islands by 2030, acting as a hub for electricity generation from multiple offshore wind farms, Denmark shows further intent to reach its targets on reducing CO2 emissions.
Being the largest infrastructure project in Danish history, the Danish energy islands will be examples of transnational cooperation and play a huge part in decarbonizing and meeting climate targets in Europe.

Green ammonia has huge potential in the global effort to substitute fossil fuels with sustainable alternatives. However, the cost of green ammonia is currently significantly higher than that of comparable ammonia from fossil fuels.
Expected to be operational in 2023, REDDAP – short for Renewable Dynamic Distributed Ammonia Plant – will be the first so-called dynamic green ammonia plant in the world. The project is a partnership of Danish industry leaders, including Topsoe, Vestas and Skovgaard Invest.
When finished, the plant will produce more than 5,000 tonnes of green ammonia from renewable energy annually. This production will prevent 8,200 tons of CO2 from being emitted into the atmosphere every year.

The Baltic Sea holds a substantial, but largely untapped potential for offshore wind power, which in the wake of the Russian invasion of Ukraine has proven yet more essential to utilise.
Published in the backdrop of the Baltic Sea Energy Security summit, hosted by Denmark, this white paper explores how to harness the Baltic Sea’s offshore energy potential.

Denmark is known for pioneering offshore wind power, having erected the first offshore wind farm back in 1991. Now the country is breaking new ground with plans to generate green energy that not only supplies the Danish electricity grid, but also its neighbours’ grids.
Located off the Danish coast in the Baltic Sea, Kriegers Flak is currently Denmark’s largest offshore wind farm with an installed capacity of 605 MW, provided from 72 Siemens Gamesa wind turbines. The wind farm became fully operational at the end of 2021, increasing Denmark’s wind production by 16 per cent.
Kriegers Flak is moreover the first project where an offshore power grid connects wind farms in both Denmark and Germany. With the Kriegers Flak Combined Grid Solution (CGS), the project cross links the national grids of Denmark and two German Baltic offshore wind farms, Baltic 1 and Baltic 2.

Green Fuels for Denmark is a unique partnership between Copenhagen Airports, A.P. Moller-Mærsk, DSV Panalpina, DFDS, SAS and Ørsted, with COWI as knowledge partner focused on developing ground-breaking hydrogen and green fuel production facilities.
The project aims to decarbonize heavy transportation by producing sustainable fuel, with the help from a established 1.3 GW electrolyser powered by 2-3 GW offshore wind.
The partnership will help decarbonise the partners’ business, while contributing significantly to Denmark’s goal of reducing CO₂ emissions by 70% by 2030, compared to 1990 levels. The fully scaled facility will reduce annual CO₂ emissions by 850,000 tons and spearhead the maturation of the technology.

Located in the city of Koege, the Braustein Breweries faced a huge challenge when they wished to accommodate their annual 15.000+ visitors with a visitor center, as well as their wish to ‘give back’ to the local community that has been very supportive of the micro brewery.
This resulted in the Braunstein Taphouse: A warehouse composed of a few sustainable materials, which has significantly reduced waste compared to similar construction projects.
The Taphouse is ‘designed for disassembly’ to make reuse of the building components a realistic option if the building cannot remain standing – either by rebuilding the whole building elsewhere or by using the materials as part of other projects.

Data centres produce a lot of waste heat, and if not taken advantage of, its potential savings are lost. That is why Nordea and Høje Taastrup District Heating wished to establish a project where a heat pump uses heat waste from Nordea’s data centre.
This resulted in a project, where Høje Taastrup District Heating establishes and operates a heat pump system which is placed in Nordea’s buildings and is connected to Nordea’s data centre. The waste heat from the data centrem which is otherwise ventilated through dry coolers, is instead increased in temperature by a heat pump and then the energy from the heat waste can be used for district heating.
This project demonstrates how it is possible to use waste heat effectively, with the heat pump to deliver district heating corresponding to approximately 700 households’ heat consumption.

Solution provider: ReMatch
While using artificial turf for sports pitches offers several benefits when compared to natural grass, disposing of it when it becomes worn out can create significant environmental issues.
Danish company Re-Match has developed a fully traceable way of recovering and separating the different materials used to produce artificial turf, making it possible to reuse the material, and providing a circular choice for sports pitches.
Every artificial turf pitch that is recycled by Re-Match results in a saving of 400 tonnes of CO2, as well as providing significant cost benefits.

In Denmark we use groundwater as the source for drinking water. This is a clean and available resource, but it can be polluted via the surface areas.
The solution to water scarcity is to preserve drinking water supplies. 3VAND represents utilities in the 3 largest cities in Denmark and offers different experiences in how to deal with water scarcity issues, including treatment of groundwater, protecting the source, and reducing water losses.
The methods used contributes to a sufficient and stable supply of high-quality drinking water in Denmark, while considering energy efficiency, environmental footprint and sustainability in general.

Solution provider: Aguardio
An estimated 5 to 8 % of all toilets worldwide leak clean freshwater down the drain. The amount of unnecessary water waste in toilets worldwide, is staggeringly high.
Aguardio has developed an easy plug and play sensor, which beeps when it detects a toilet leaking clean water.
Already within the first week of installing Leak Sensors, several running toilets are usually detected. The sensor’s potential to reduce water waste is therefore considered high.
