BBC Inside Science: Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

BBC Radio 4 - BBC Inside Science, Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano.

Halfway to net zero in the UK; hydrogen to replace fossil fuels; Fagradalsfjall, Iceland’s active volcanic system.
Presented by Gaia Vince.

The UK is reportedly halfway towards meeting its 2050 target of "net zero" carbon emissions. How did we get there and how will we achieve the next stage? 

‘UK greenhouse gas emissions in 2020 were 51% below 1990 levels, according to a new Carbon Brief analysis. This means the UK is now halfway to meeting its target of “net-zero” emissions by 2050.’ Simon Evans explains his predictions from the report, outlines how we define net zero and what is required from the next few decades to ensure that the UK meets its 2050 goal. 

Much of Europe is attempting to replace fossil fuels, transforming transport and domestic heating to run on electrical alternatives, such as batteries and heat pumps. But where electrification isn’t possible or cost effective, such as in many homes, an alternative is still needed. Natural gas is responsible for over 30% of the UK’s total carbon emissions. Hydrogen would, theoretically, appear to be the perfect alternative, as combustion only produces water as a by product. Gaia discusses the options with hydrogen strategist, Dr Jenifer Baxter, and Dr Angela Needle of Cadent explains the pilot projects the company is carrying out to introduce 20% hydrogen into gas going into our homes. 

Last Friday, Fragradalsfjall began erupting for the first time in 800 years. The volcanic system is located in the West of Iceland close to the capital city of Reyjkavik. Dr Evgenia Ilynskaya of Leeds University has been out measuring the gases emitted by the eruption and she describes the experience of working on an active volcanic system.

Intelligent speech, the most insightful journalism, the wittiest comedy, the most fascinating features and the most compelling drama and readings anywhere in UK radio.
