What if we never run out of oil? From certainty of "peak oil" to "peak demand".

The COVID-19 pandemic sent the oil industry into turmoil on a scale not seen since the 1970s. While the sector appears to be recovering, questions remain about the extent to which the pandemic has offered a glimpse into the possible future of the industry. This future is critical to the success of climate change mitigation, which requires significant cuts to the carbon dioxide emissions from using oil for energy.

The greenhouse gas emissions performance of cellulosic ethanol supply chains in Europe.

Background: Calculating the greenhouse gas savings that may be attributed to biofuels is problematic because production systems are inherently complex and methods used to quantify savings are subjective. Differing approaches and interpretations have fuelled a debate about the environmental merit of biofuels, and consequently about the level of policy support that can be justified. This paper estimates and compares emissions from plausible supply chains for lignocellulosic ethanol production, exemplified using data specific to the UK and Sweden.

New improvements for lignocellulosic ethanol.

The use of lignocellulosic biomass for the production of biofuels will be unavoidable if liquid fossil fuels are to be replaced by renewable and sustainable alternatives. Ethanol accounts for the majority of biofuel use worldwide, and the prospect of its biological production from abundant lignocellulosic feedstocks is attractive. The recalcitrance of these raw materials still renders proposed processes complex and costly, but there are grounds for optimism.

The commercial performance of cellulosic ethanol supply-chains in Europe.

Background: The production of fuel-grade ethanol from lignocellulosic biomass resources has the potential to increase biofuel production capacity whilst minimising the negative environmental impacts. These benefits will only be realised if lignocellulosic ethanol production can compete on price with conventional fossil fuels and if it can be produced commercially at scale. This paper focuses on lignocellulosic ethanol production in Europe.
