Marine renewables are technologies that generate electricity from tide and wave motion. They produce electricity without greenhouse gases, and could provide economic benefits for the UK. However, the technologies have been slow to develop, despite previous projections of growth. This POSTnote examines the causes of this delay and how the sector might develop.

Nuclear fusion (239 KB, PDF)
Since the first hydrogen bomb test showed that the sun’s fusion energy processes could be reproduced on earth, governments and others have funded research into harnessing fusion to produce electricity. Over 30 years later, many national and international research efforts are about to be coordinated into a global project on nuclear fusion – the International Thermonuclear Experimental Reactor (ITER).
This POSTnote examines the international progress towards power from nuclear fusion and its future prospects.

Key infrastructure areas such as transport, energy, water and telecoms are vital to society and the economy. Evidence suggests that climate change is increasing the frequency and severity of extreme weather events, posing a risk to infrastructure systems. This POSTnote looks at the main climate-related risks to the UK’s economic infrastructure, measures to reduce these risks and the main challenges to implementing resilience measures.

According to global climate and economic models, removing greenhouse gases from the atmosphere will be necessary to limit global warming to 1.5˚C. Among Greenhouse Gas Removal (GGR) techniques, these models assume that Bioenergy with Carbon Capture and Storage (BECCS) could play a prominent role. This POSTnote summarises why BECCS has been included in the models, outlines the challenges and trade-offs of deploying at scale, and considers policy options for supporting its development.
