Part of solving the global challenge of securing sustainable energy for all is to match demand with supply. Matching consumption with production becomes a more acute challenge in a sustainable energy system with increasing amounts of renewable energy that offer fluctuations and unpredictability. For example, in windy periods, providing large amounts of clean energy is a relatively simple task and in times with little wind, we have limited or zero access to clean energy.
To successfully match energy demand with supply, a smart energy system that offers high amounts of flexibility to accommodate fluctuations in the energy supply is needed. A smart and flexible energy system can be achieved in a number of ways depending on a country’s resources and context, and no single technology can do the trick alone.
Innovative energy storage: 600-degree hot stones are used to store green electric power
A test model of a new type of energy storage has been inaugurated at DTU Risoe, Denmark. The innovative technology has a large potential for storing wind and solar energy. NIRAS consulted on the model’s design.
Flexible power plants increase the share of renewable energy in China
A Danish-Chinese energy partnership supports China in increasing the flexibility of its coal-fired power plants. This has resulted in more green energy in the electricity system, corresponding to nine 800 MW offshore wind farms, and reduced CO2 emissions by 22 million tonnes, equivalent to 63 per cent of the CO2 emissions from the Danish energy consumption.
EnergyLab Nordhavn – New Urban Energy Infrastructures The project utilizes Copenhagen’s Nordhavn as a full-scale smart city energy lab and demonstrates how electricity and heating, energy-efficient buildings and electric transport can be integrated into an intelligent, flexible and optimized energy system. The project participants are: DTU, City of Copenhagen, CPH City & Port Development, HOFOR, Radius, […]
ECOGRID 2.0: Flexible electricity consumption in private households
In a future where energy comes from renewable energy sources, we need to be able to control the electricity consumption, taking into account the fluctuating electricity production. Here, it is an advantage that consumers can actively turn down their electricity consumption or move it to periods when more electricity is produced. Remote controlling of heat […]
Cobra unleashes green energy flows between Denmark and Holland
For many years, the Danish electricity system has been connected to Norway, Sweden and Germany. As of midnight Sunday, the Netherlands can also be added to the list. Power from Danish wind turbines and solar cells can be now supply Dutch consumers directly via the so-called Cobra cable.
From Policy to Action – Implementation of the European Energy Union
When looking at the global climate challenges, the energy system is one of the biggest obstacles towards a carbon-free and net-zero future. The European Union has set ambitious objectives for an energy system, which integrates renewable energy and energy efficiency, as well as enabling a well-functioning energy market. These elements in combination can support a […]
Three ways to huge CO2 reductions in Denmark
Utilising linkages between sectors to best use renewable energy has a huge potential in the reduction of CO2 emissions. Digitised and energy efficient consumption, electrification and a comprehensive renewable energy system are all variables in the quest for huge CO2 reductions.
Delivering a carbon neutral Europe by 2050: the role of offshore wind energy takes centre stage in Copenhagen
Under the theme of ‘Our energy, our future’, Copenhagen is hosting the WindEurope Offshore 2019 congress, which sets the role of offshore wind energy in decarbonising Europe in the spotlight. Nine thousand guests and 450 exhibitors will visit the Danish capital this week as part of the event.
Danish Minister: we are obligated to help countries turn growth into green growth
Yesterday, the Danish Minister for Climate, Energy and Utilities met the international press at State of Green in Copenhagen to discuss the green transition, climate ambitions and Denmark’s international role in mitigating the effects of climate change.
Danish-German partnership in green spotlight: German minister visiting Denmark for green solutions
Denmark has the experience and technology to help lift the big promises made at the several green summits during the autumn. The determination to live up to these promises is clearly marked by the visit to Denmark by the minister of the Environment, Climate and the Energy Sector from the German state Baden-Württemberg. The visit will showcase concrete Danish green approaches and solutions.
From Coal to Biomass at Avedøre Power Station
Ramboll works innovatively with the transformation of the energy sector from fossil fuels to renewable energy. At Avedøre Power Station (in English: Avedore Power Station) in Copenhagen, Ramboll is assisting Ørsted in converting power station units from coal to biomass. The plant itself is unique in its efficient use of fuel and its ability to produce heat […]
Sustainable Combined Heat and Power
The most valuable form of energy is electricity. Unfortunately, large scale storage is difficult and electric power must be produced when used. A base load in the electric system from wind power, hydro power or other renewable resources delivers electrical energy whereas thermal plants (nuclear or combustion based) supply electricity at a specified power and […]
Offshore wind to be integrated in the energy network
There is in fact more wind energy resources than we need, and the largest wind turbines can produce electricity at a competitive price. However there are problems: the onshore resources are limited for environmental reasons the electricity is generated as the wind blows – sometimes when it is not needed and it can not be […]
Offshore Windfarm, Anholt Denmark, Detailed design
Ramboll performs Detailed Foundation Design, Design of Substation Platform, Environmental Impact Assessment (EIA) and Telecom for The Anholt Offshore Windfarm which is one of the largest offshore windfarms in the world today. The customer of the project is Energinet.dk (Substation platform, EIA and Telecom) and Ørsted (Detailed Foundation Design). Energinet.dk is an independent public company owned […]
Wind energy moving ahead
This white paper takes you through all the elements of the success story of wind energy in Denmark. From the starting point and what we now consider small-scale wind turbines to the projects and technologies that push the bar and the ambitions for wind energy as a source of renewable energy. We hope you will be inspired.
District Energy holds a vast potential for energy efficiency in urban areas. This White Paper highlights the key elements for success in district heating and cooling. It covers aspects from regulation and planning, efficient production of thermal energy, to storage, distribution and end user solutions.
