Research review (peer-reviewed)abstract
- Phasing out fossil fuels requires destabilizing incumbent regimes while protecting vulnerable groups negatively affected by fossil fuel decline. We argue that sequencing destabilization and just transition policies addresses three policy problems: phasing out fossil fuels, transforming affected industries, and ensuring socio-economic recovery in fossil resource-dependent regions. We identify the key mechanisms shaping the evolution of the three systems associated with these policy problems: (i) transformations of technological systems addressed by the socio-technical transitions literature, (ii) responses of firms and industries addressed by the management and business literature and (iii) regional strategies for socio-economic recovery addressed by the regional geography and economics literatures. We then draw on Elinor Ostrom’s approach to synthesize these different bodies of knowledge into a diagnostic tool that enables scholars to identify the phase of decline for each system, within which the nature and importance of different risks to sustained fossil fuel decline varies. The main risk in the first phase is lock-in or persistence of status quo. In the second phase, the main risk is backlash from affected companies and workers. In the third phase, the main risk is regional despondence. We illustrate our diagnostic tool with three empirical cases of phases of coal decline: South Africa (Phase 1), the USA (Phase 2) and the Netherlands (Phase 3). Our review contributes to developing effective policy sequencing for phasing out fossil fuels.

Pathway to a land-neutral expansion of Brazilian renewable fuel production

Journal article (peer-reviewed)abstract
- Biofuels are currently the only available bulk renewable fuel. They have, however, limited expansion potential due to high land requirements and associated risks for biodiversity, food security, and land conflicts. We therefore propose to increase output from ethanol refineries in a land-neutral methanol pathway: surplus CO2-streams from fermentation are combined with H2 from renewably powered electrolysis to synthesize methanol. We illustrate this pathway with the Brazilian sugarcane ethanol industry using a spatio-temporal model. The fuel output of existing ethanol generation facilities can be increased by 43%–49% or ~100 TWh without using additional land. This amount is sufficient to cover projected growth in Brazilian biofuel demand in 2030. We identify a trade-off between renewable energy generation technologies: wind power requires the least amount of land whereas a mix of wind and solar costs the least. In the cheapest scenario, green methanol is competitive to fossil methanol at an average carbon price of 95€ tCO2−1.
