Why Does Denmark Face Gas Shortages Despite Renewable Energy?

Denmark, renowned for its renewable energy initiatives, remains dependent on natural gas as an essential part of its energy mix. However, the recent increase in gas prices and supply concerns have sparked debates in the country. The Danish government and energy agency are deeply concerned about potential disruptions in the gas supply, highlighting the challenges of integrating renewable energy into a complex energy ecosystem.

Integrating Renewable Energy with Backup Solutions

For countries like Denmark, renewable energy sources such as wind and solar play a crucial role in the overall energy mix. However, these sources are intermittent, meaning they may not always produce sufficient power, especially when the wind doesn't blow or the sun doesn't shine. To ensure a stable and reliable energy supply, Denmark and other nations need to have a backup power solution in place.

Taking a look at Denmark's energy supply, the graph breaks down the different sources: red for natural gas, brown for coal, orange for solar, teal for wind, blue for hydro, and dark brown-green for biomass. While Denmark has a significant amount of wind energy, it still relies heavily on imported hydroelectric power from neighboring Nordic countries in situations where there is a lack of wind or solar power.

Backup Hydroelectric Power from Nordic Countries

Denmark experiences peak demand for energy during winter, and the winter of 2022-2023 saw a particularly noticeable gap between supply and demand. This gap was filled by importing hydroelectric power from neighboring Nordic countries, indicated by the green portion of the graph above. This backup plan is critical for ensuring a stable grid, especially during periods of low wind or solar activity.

Despite its extensive wind power infrastructure, Denmark cannot completely rely on renewables due to their intermittent nature. The reliance on imported hydroelectric power underscores the necessity of diversified energy sources for maintaining a stable energy supply.

Renewable Energy and Domestic Gas Production

Denmark does generate a significant portion of its electricity from renewable sources. However, the country still lacks sufficient domestic natural gas production to meet all its needs. According to Kristoffer Bttzauw head of the Danish Energy Agency, “We still have gas in Denmark and consumers can still have gas delivered, but we have plans ready if the situation worsens.”

Daniel's energy profile includes natural gas for heating, with around 380,000 households using gas boilers for heating purposes. While Denmark has historically been a net exporter of natural gas, this is changing due to the renovation of its Tyra field in the North Sea, which is expected to reopen in mid-2023. Currently, Denmark imports about 75% of its gas consumption via Germany.

The Tilt Toward Renewable Energy and NUCLEAR Power Plant Closure

Denmark's energy strategy has traditionally included a mix of renewable and non-renewable energy sources. Before the recent shift towards renewable energy, the country heavily relied on the Barsebck nuclear power plant in Sweden, which supplied approximately one-third of Denmark's electricity. After concerns about radiation and public protests, the plant was closed.

The closure of the Barsebck nuclear plant highlighted the potential risks associated with non-renewable energy sources and the importance of diversifying the energy mix. The replacement of nuclear power with renewable energy sources has been a gradual process, requiring careful planning and coordination to ensure a stable and sustainable energy supply.

In conclusion, Denmark's energy landscape is a perfect example of the challenges faced by countries transitioning to renewable energy. The interplay between natural gas, renewable energy, and imported hydroelectric power highlights the importance of having a reliable backup plan. As the world continues to shift towards more sustainable energy solutions, countries like Denmark will need to balance the benefits of renewable energy with the practical necessity of ensuring a stable and reliable energy supply.
