Biogas turns waste into value

Decarbonising energy systems requires solutions tailored to local conditions. While electrification is the preferred option for many applications, sectors such as high-temperature industrial processes still require renewable gaseous fuels. At the same time, agriculture produces large volumes of manu

Integrating power and gas systems through Power-to-Gas in Sønderborg

The growing share of electricity from wind and solar increases variability in energy supply. During periods of high production and low demand, renewable electricity cannot always be used, leading to curtailed wind turbines. At the same time, certain industries require stable, high-temperature energy

The electric farm that harvests energy and captures CO₂

Agriculture accounts for a significant share of global greenhouse gas emissions. Reducing emissions while maintaining food production is therefore a major challenge for the sector. At the same time, new policies are accelerating the need for change. Denmark will introduce a CO₂ tax on agriculture fr

Kwinana: Australia’s first waste-to-energy plant

22 January 2026

Australia generates more than 70 million tonnes of waste annually. While around 60% is recycled, the remaining 40% is typically sent to landfills, where it contributes to methane emissions and long-term environmental impacts. At the same time, Australia’s energy system remains heavily dependent on f

Urban air pollution

With urbanisation set to increase, air pollution will affect even more people in the future if no action is taken. Through strict environmental legislation and air quality monitoring, Denmark has reduced atmospheric pollution in most areas to less than one-fifth of the levels during the late 70s.

Climate change adaptation

Expanding mitigation to include adaptation in dealing with climate change, enables a holistic view that can combat previous negative social, environmental, and economic impacts and result in both climate resilient and more liveable places to live. Over the next 15-20 years, Denmark will spend more than EUR 5 billion on adapting its cities to climate changes.

Smart cities

As the pace of urbanisation quickens, cities face immense challenges related to waste management, mobility, climate adaptation and energy. However, as their political, economic, and technological power grows, cities can harness this trend to act as leaders in the green transition and drivers of the green economy. Cities need smart solutions to ensure that they are optimised for sustainable economic activity, energy consumption, and an improved environmental impact.

Urban mobility

Cities must be built for people to be sustainable, healthy, and liveable. Targeted policy-making with urban mobility in mind is a strong reinforcement of these objectives. The key is to acknowledge the importance of city space and city life as an attractive, informal, and democratic meeting place for the city residents.
