The cost of producing hydrogen gas from renewables is forecast to fall sharply over the next decade, providing an affordable fuel to decarbonise the energy and transport sectors. In Germany and Texas, RES hydrogen costs could fall to $1.40 a kilogram by 2030 from the current range of $2.50 to $6.80, according to research published in Nature Energy.
Siemens, the state of Saxony and the Fraunhofer Institute have signed a ‘future pact for Görlitz’ and committed to invest around €30 million to develop a competence center for hydrogen technologies. The initiative is meant to ease the effects of region’s structural transformation which has been hit by Siemens’ closure of a long-running turbine manufacturing site.
Power system flexibility is a prerequisite of the clean energy transformation. Fossil power plants were for long deemed vital to ensure flexible supply and system inertia, but “if modern wind and solar power plants are technically able to provide frequency regulation, they should be allowed access to ancillary services, as was done in Spain,” said Enrique Gutierrez, energy analyst at the International Energy Agency (IEA).
