Renewable Energy from the Ocean and Tides: A Viable Renewable Energy Resource in Search of a Suitable Regulatory Framework
Over the past few years there has been significant international interest in the development of offshore wind energy as a source of renewable energy especially in Europe. However, the wind is not the only source of renewable energy in offshore areas. The broad suite of technologies collectively known as ocean energy are also beginning to emerge as a viable base-load source of renewable energy. Ocean energy technology involves a wide range of engineering technologies that are able to obtain energy from the ocean using a variety of conversion mechanisms including hydrokinetic energy (where the energy of ocean (or fluvial) currents and tides is captured by devices which are installed under the surface of the water); wave energy (where the energy of the surface wind waves is used to produce electricity by a variety of devices installed on the surface of the sea); ocean thermal energy or OTEC (which uses the temperature differential between cold water from the deep ocean and warm surface water) and; Osmotic energy (which relates to the pressure differential between salt and fresh water).
Ocean energy technology involves a range of engineering technologies that are able to obtain energy from the ocean using a variety of conversion mechanisms. Over the past few years there has been significant progress towards the development of commercial scale operations of ocean energy, especially hydrokinetic energy (where the energy of ocean (or fluvial) currents and tides is captured by devices which are installed under the surface of the water) and wave energy (where the energy of the surface wind waves is used to produce electricity by a variety of devices installed on the surface of the sea). Ocean energy is now on the threshold of providing a reliable base-load source of renewable energy on a commercial scale. While technological barriers are being overcome the lack of clear regulatory frameworks in many countries is now emerging as a barrier to wide-scale development of ocean energy. Regulatory frameworks need to be developed to more suitably deal with the relatively benign environmental impacts of ocean energy in particular. Where regulatory regimes do exist there is also a need for further streamlining of approval processes. The industry also needs feed-in tariffs to promote the widescale adoption of this technology.

Um die unbestritten notwendige Erhöhung des Anteils der Erneuerbaren Energien an der Stromerzeugung zu ermöglichen, ist ein massiver Ausbau der Speicher für elektrische Energie unabdingbar. Als geeignete Technologien für die benötigten Größenordnungen sind lediglich Pumpspeicherkraftwerke, Druckluftspeicher und chemische Energieträger einsetzbar.
Intelligente Gasnetze – Smart Gas Grids

Zukünftige Energiesysteme werden bestrebt sein, die Last mehr und mehr der durch Erneuerbare Energien geprägten Energieerzeugung nachzuführen. Hierbei werden Energiespeicher unterschiedlicher Kapazitäten von erheblicher Bedeutung sein und können sogenannte Systemdienstleistungen übernehmen. Smarte Gasnetze werden in Kooperation mit den Stromnetzen einen erheblichen Beitrag zur Schaffung von effizienten Energieinfrastrukturen leisten und somit die Integration erneuerbarer Energien unterstützen.
