The EU’s ReFuelEU Aviation and the UK’s SAF Mandate place requirements on fuel suppliers to bring alternative aviation fuels to market. In parallel, financial support for alternative fuels comes from the EU’s reimbursement scheme, which subsidises some fraction of the cost difference paid by airlines, and the UK’s guaranteed strike price (GSP), which shields SAF […]
Environmental impacts of expanding the supply of maritime biofuels for the International Maritime Organisation targets The UN’s International Maritime Organisation (IMO) is in the process of evaluating proposals for binding targets aimed at decarbonising international shipping. Whatever the ultimate form of this regulation, there will likely be significant implications for the production of biofuels for […]
How e-fuels can mitigate biodiversity risk in EU aviation and maritime policy This report, commissioned by Opportunity Green on behalf of the Skies and Seas Hydrogen-fuels Accelerator Coalition (SASHA), explores the biodiversity risks associated with the EU’s efforts to decarbonise aviation and maritime transport. The ReFuelEU Aviation and FuelEU Maritime regulations aim to engender a […]
In this paper for the International Council on Clean Transportation we consider the industrial development implications of the targets for alternative aviation fuel supply that are being introduced throught he UK’s SAF Mandate.
Cerulogy worked with the Clean Air Task Force to develop an online tool to allow users to explore the lifecycle emissions of conventional and renewable hydrogen production. It allows users to review the full lifecycle emissions of hydrogen while changing a number of assumptions, including the methane leakage rate for natural gas supply, the electricity […]
This report for Transport and Environment, written in partnership with David Calderbank Consulting, considers options for the development of alternative transport energy policy in the UK under the Renewable Transport Fuel Obligation (RTFO). It discusses issues including adding renewable transport fuel obligations on aviation and marine fuel use, crediting renewable electricity use by electric vehicles, […]
Within the European Union’s recast Renewable Energy Directive support is available not only to biofuels but also to ‘renewable fuels of non-biological origin’ (electrofuels) and to ‘recycled carbon fuels’ (fuels produced taking advantage of fossil energy in solid and gaseous waste streams). This report for the International Council on Clean Transportation provides an introduction to […]
In this report for FuelsEurope we present a proposal to use a fuel decarbonisation credit added to the heavy duty efficiency vehicle efficiency standard to accelerate deployment of advanced alternative fuels and of green hydrogen use and CCS at refineries.
