Hydrogen could account for a third of energy use by 2050, the Government has said as it publishes a strategy for boosting use of the low carbon fuel, but will it push up bills for consumers? Potentially. Subsidies for new technology such as offshore wind went on to consumer electricity bills and the Government is considering a similar approach for hydrogen. Hydrogen has a number of end users and would be replacing different fuels such as diesel in vehicles or natural gas in power and industry, so would have impacts on different sectors and consumers. How to pay for the transition to clean energy, and who bears the cost, is a key focus of the Government at the moment.
