Renewable energy systems are relevant in all industries and activities which require energy. This can span from heavy duty industrial processes to the electricity used in your home. To achieve efficient systems natural resource availability and stability needs to be assessed, this will allow for optimal and reliable production. With variable energy sources it is crucial to obtain energy balance in the system to create predictability for the costumer and the energy market. By using hydrogen or other energy carriers, it is possible to store energy for peaks and contribute to energy balance.
Another important factor in a renewable energy system is the end user. In addition to producing electricity or heat from the natural energy sources, we need to ensure efficient use of the energy produced and reduce waste. This is especially relevant in the construction industry where old buildings without proper insulation and energy distribution systems are wasting energy continually. There is a constant need to increase efficiency of energy consuming processes to obtain optimal energy systems.
Power-to-X is an example of how one can utilise excess renewable energy to create energy carriers. This will play a major role in the future of renewable energy systems.
In the future, it is expected to be a wide variety of energy sources in the energy mix, such as renewable, oil, gas, coal and nuclear. To achieve our global climate goals renewable energy needs to be front and center in this mix.
