Industrial trade unions in Europe and North America often struggle to develop a coherent strategy on climate change and overcoming fossil fuel production patterns. Trade union policy in the German steel industry is an interesting example of this: the "green" restructuring is firmly in favour, as...

On 11 April 2024 the European Parliament adopted the Renewable and Natural Gases and Hydrogen (RNGH) Directive and the RNGH Regulation – otherwise known as the Decarbonised Gas and Hydrogen Package – and published both documents on 12 April 2024. Once approved by the Council and published in...

Contracts for Difference (“CfDs”), previously mainly known as financial hedging instruments, are increasingly seen as the method of choice for incentivising investment in clean energy technologies. In the power sector, the CfD mechanism has emerged as the preferred arrangement to provide the...

This paper examines the viability of green ammonia (NH3) as a marine fuel in the transition to decarbonized shipping. While there is no singular solution for achieving decarbonization, there is increasing recognition on the pivotal role of green ammonia in decarbonizing the shipping sector. The...

The iron/steel industry is one of the highest emitting sectors, contributing 7-9% of overall global emissions. As population and economic growth will demand more steel as a key building block of society, the need to decarbonize the sector is critical. This paper assesses the financing...

Hydrogen produced with minimal or no carbon emissions is often expected to become an important tool for meeting climate objectives and decarbonising national economies that currently mostly rely on fossil fuels. Despite initial expectations, it seems unlikely that clean hydrogen will be used by...

Low carbon hydrogen (whether based on renewable or nuclear electricity, or fossil fuels with carbon capture) is a means to decarbonise sectors of the economy which are hard to electrify. Its business model is heavily dependent on government intervention (e.g. mandatory targets, subsidies,...

This policy brief addresses the critical issue of phasing out diesel subsidies in Colombia and underscores the urgent need for coordinated action and strategic planning. The Colombian government views the sub­sidy phase-out as part of its energy transition strategy, proposing investments in...

As the power sector is the largest GHG emitter, it is important to investigate the fuels used in this sector. In 2023, coal was the primary source of electricity supply, accounting for 35.9%. Natural gas came in second, representing 23%. Asia has the largest number of coal plants in operation,...

The Oxford Institute for Energy Studies started researching the role of hydrogen in the energy transition in 2020. Since then the interest in hydrogen has continued to grow globally across the energy industry. A key research question has been the extent to which clean hydrogen can be scaled up...

The transition to a hydrogen-based economy is gaining momentum in both Germany and the European Union (EU). Used as an energy carrier, hydrogen holds the promise of freeing hard-to-decarbonise sectors like heavy industry, aviation, and maritime trade from their emissions. At the same time,...
