The solar-photovoltaic- (PV-) powered project, being enforced for the Dubai Electricity and Water Authority (Dewa), entails electrolyzing water into chemical element and hydrogen using solar-generated electricity. Varied uses for the hydrogen are piloted throughout the project.
Speaking to a visiting international contingent of journalists at Siemens’ offices at the Masdar town sustainability-focused precinct on Sunday, Siemens geographic area senior VP for strategy and business development Manuel Kuehn averred that green hydrogen production had become commercially viable, given the decline within the value of each intermittent and continuous renewable energy over the past decade. The levelised value of utility-scale solar PV, as an example, had fallen from concerning $394/MWh in 2009 to a median of $40/MWh in 2018, whereas Chile, Mexico and Saudi Arabia had achieved levels as low as $21.50/MWh, $19.70/MWh and $17.90/MWh severally by 2017, Kuehn said. Owing to the declining value, solar PV installations worldwide had enlarged from 15 GW in 2008 to 391 GW in 2017.
Kuehn aforementioned the levelised value of wind-generated electricity had conjointly declined sharply – from as high as $169/MWh in 2009 to as low as $29/MWh – prompting a surge in international installations from 115 GW in 2008 to 514 GW in 2017.
The falling costs of wind- and solar-generated electricity – yet as of continuous renewables like geothermic, biomass and electricity – had motor-assisted in facilitating the industrial viability of manufacturing inexperienced hydrogen for varied uses.
