Several energy scenario studies consider concentrated solar power (CSP) plants as an important technology option to reduce the world's CO2 emissions to a level required for not letting the global average temperature exceed a threshold of 2–2.4 °C. A global ramp up of CSP technologies offers great economic opportunities for technology providers as CSP technologies include highly specialised components. This paper analyses possible value creation effects resulting from a global deployment of CSP until 2050 as projected in scenarios of the International Energy Agency (IEA) and Greenpeace International. The analysis focuses on the economic opportunities of German technology providers since companies such as Schott Solar, Flabeg or Solar Millennium are among the leading suppliers of CSP technologies on the global market.
This study provides insight into the feasibility of a CO2 trunkline from the Netherlands to the Utsira formation in the Norwegian part of the North Sea, which is a large geological storage reservoir for CO2. The feasibility is investigated in competition with CO2 storage in onshore and near-offshore sinks in the Netherlands. Least-cost modelling with a MARKAL model in combination with ArcGIS was used to assess the cost-effectiveness of the trunkline as part of aDutch greenhouse gas emission reduction strategy for the Dutch electricity sector and CO2 intensive industry. The results show that under the condition that a CO2 permit price increases from €25 per tCO2 in 2010 to €60 per tCO2 in 2030, and remains at this level up to 2050, CO2 emissions in the Netherlands could reduce with 67% in 2050 compared to 1990, and investment in the Utsira trunkline may be cost-effective from 2020–2030 provided that Belgian and German CO2 is transported and stored via the Netherlands as well. In this case, by 2050 more than 2.1 GtCO2 would have been transported from the Netherlands to the Utsira formation. However, if the Utsira trunkline is not used for transportation of CO2 from Belgium and Germany, it may become cost-effective 10 years later, and less than 1.3 GtCO2 from the Netherlands would have been stored in the Utsiraformation by 2050. On the short term, CO2 storage in Dutch fields appears more cost-effective than in the Utsira formation, but as yet there are major uncertainties related to the timing and effective exploitation of the Dutch offshore storage opportunities.
Considering the traditional coal-based energy infrastructure in the German state North Rhine-Westphalia the question arises how to face the needs of embanking climate change. To reduce greenhouse gas intensive electricity generation in the Ruhr area, the introduction of carbon capture and storage (CCS) is an option of particular relevance. The paper investigates and discusses possibilities of setting up a CCS infrastructure in NRW. It shall clarify whether, and possibly how, highly efficient conventional fossil fired power plants could be refitted with CO2 capture to flexibly react to potentially changing climate policy conditions and to keep up with the market.
Ende Dezember 2008 wurde im Europäischen Parlament die "Richtlinie über die geologische Speicherung von CO2" (auch als CCS-Richtlinie bezeichnet) verabschiedet, die eine Schlüsselrolle für die Entwicklung und die Umsetzung von Projekten der CO2-Abscheidung und -Speicherung (CCS) spielt. Der Artikel erläutert den Zusammenhang der CCS-Richtlinie mit dem Energie- und Klimapaket der EU, stellt die wesentlichen Inhalte der Richtlinie vor, zeigt die energiewirtschaftlichen Implikationen auf und arbeitet heraus, welche Regelungen zur Umsetzung der Richtlinie nun vom deutschen Gesetzgeber erfolgen müssen.
