Research finds hydrogen could play key role in decarbonising UK power system

Aurora Energy Research has said hydrogen can play a key role in the decarbonisation of the UK’s power system, offering a low-carbon alternative to gas-fired generation.

According to its latest research, the UK could produce all of the hydrogen needed to fire peaking plants by 2035 by using renewable and nuclear electricity, where 8TWh of renewable generation would be curtailed, under the researcher’s base case.

By Aurora’s estimations, electrolysers would need 13TWh of input electricity to produce the amount of hydrogen needed to fire peaking plants instead of gas. Under its base case, curtailment falls 5TWh short.

However, by installing an additional 7.5% of renewable and nuclear capacity by 20305, relative to the 8TWh base case, the UK could enable enough curtailed generation to meet peak plant hydrogen demand.
