16 May 2019 Economic and sustainability impacts of an aviation tax: New variants
In 2018 CE Delft carried out a study on the economic and sustainability impacts of a number of variants of an aviation tax (CE Delft, 2018). After the report was completed, the Ministry of Finance indicated it would like several new variants to be examined in which the tax would cover not only passenger departures but also cargo aircraft. The present report analyses the economic and sustainability impacts of these variants. It also recalculates the impacts of two of the earlier variants, as a new version of the AEOLUS model is now available.
3 May 2019 - Press release Shipping emissions: International measures needed to cut operational greenhouse gas emissions of existing fleet by 2030
The international shipping sector needs to quickly adopt short-term policy measures to cut operational greenhouse gas (GHG) emissions of the existing fleet, according to a new study. The study concludes that only a subset of potential policy options, namely those that mandate changes in how the existing fleet is operated can achieve the significant effect required to meet the sector’s emission reduction objectives. Examples of these policies are speed limits or mandatory limits on operational efficiency or shaft power.
The study out today led by CE Delft and UMAS, funded by the European Commission, analyses potential short-term measures listed in the International Maritime Organization’s (IMO) initial strategy on the reduction of GHG emissions from ships.
The strategy, adopted in April 2018, includes commitments to peak emissions as soon as possible, to improve the carbon intensity of international shipping by at least 40% by 2030 (compared to 2008), and to reduce the total annual emissions by at least 50% by 2050 (compared to 2008).
The specific policy measures that can turn those commitments into practice are being considered by the IMO and will be discussed as part of the IMO negotiations in London next week. The measures considered in the study are those that could enter into force imminently and help to control GHG emissions over the period between now and 2030.
As requested by the IMO Marine Environment Protection Committee in October last year (MEPC 73), several countries have submitted concrete proposals for reduction measures. These include proposals for speed limits, for the improvement of ship’s operational efficiency as well as a proposal for a shaft power limit. All proposals are assessed in the study to be compatible with the IMO’s objectives, if they are sufficiently strict.
The study also considered options for non-mandatory limits that use existing policy (Ship Energy Efficiency Management Plan, SEEMP) to incentivise greater efficiency. Such non-mandatory limits were deemed ineffective, as they would reduce GHG emissions by not more than 2% from the expected business-as-usual levels.
The IMO meeting in May will also discuss options to further strengthen the current internationally agreed energy efficiency rules under the Energy Efficiency Design Index (EEDI) regulation. The study analysed the emissions reduction impacts of further increasing the stringency of this regulation.
The study found that these changes would not bring about any significant GHG reductions by 2030. However, they would achieve more impact further into the future.
Press release - Feasibility study into blue hydrogen
Today, 29-8-2018, CE Delft publishes the report Feasibility study into blue hydrogen . The study identifies blue hydrogen as a technical feasible, industrial scale CO2-reduction measure. We want to inform you about the publications, share contact details for further contact and offer the possibility that CE Delft presents these results and additional information on (blue) hydrogen. The main conclusions of the report are that blue hydrogen has a low CO2 -footprint and the chain is technically feasible.
An greenhouse gas emission analysis has been performed on steam reforming processes (SMR and ATR) and electrolysis processes, for both 2018 and 2030 state-of-the-art technology. The CO2 footprint for blue hydrogen is determined to be lower than green hydrogen produced from Norwegian electricity (17 g CO2/kWh), 0,82-1,14 and 1,13 kg CO2/kg H2 respectively. This influences the debate regarding the sustainability assessment of blue and green hydrogen.
The research is a system analysis on the five process steps: production via steam reforming, carbon capture and storage, transport in pipelines, daily and seasonal storage and industrial applications. The chain is viable and can guarantee industrial volume and economic attractive production many years before green hydrogen. Blue hydrogen offers the potential of solving downstream hydrogen challenges regarding transport and applications now, enabling the transition towards green hydrogen in the future.
