While renewables like hydro, solar and wind power are widely known, an energy source gaining momentum as a highly versatile energy source of tomorrow is hydrogen, particularly green hydrogen. 'Renewables plus hydrogen' - almost all that we need. Hydrogen from renewable power is technically viable today, says the International Renewable Energy Agency (IRENA), noting that its price will … It can be produced as a gas or liquid, or made part of other materials, and has many uses such as fuel for transport or heating, a way to store electricity, or a raw material in industrial processes.
Falling costs for hydrogen produced with renewable energy, combined with the urgency of cutting greenhouse-gas emissions, has given clean hydrogen unprecedented political and business momentum. About the author: Dale Gardner is the associate laboratory director for Renewable Fuels & Vehicle Systems at the National Renewable Energy Laboratory (NREL), a US Department of Energy laboratory located in Golden, Colorado, USA.His research, development, and demonstration technology portfolio at the lab includes biofuels, hydrogen and fuel cells, and advanced vehicle technologies. Renewable hydrogen can be introduced in small amounts, displacing only a fraction of the plant's natural gas consumption but demonstrating and de-risking the technologies. : the gas grid, the storage tanks of hydrogen refuelling stations, and salt caverns). Renewable hydrogen is renewable energy - solar and wind, tidal and wave energy - stored safely in the form of hydrogen gas, made from water. Then, the renewable energy farms and electrolyzers can be scaled-up in stages, eventually replacing all the natural gas requirements and completing the conversion of a fossil asset to a renewable asset. Indeed, producing hydrogen via renewable energy is not a new idea. Hydrogen is incredibly versatile and, as either a feedstock or an energy vector, green hydrogen offers ways to decarbonize a range of sectors – including long-haul transport, space heating and industry (particularly fertilizer and steel). direct electrification to enable the ambitious roll-out of renewables in the next decade, across all energy vectors and key sectors of the economy. by using hydrogen as substitute for natural gas by feeding it into existing pipelines, as fuel for fuel-cell vehicles or power plants, or as feedstock for the hydrogen processing industry. However, it can’t carry all the world’s energy demand on its shoulders, writes Frank Wouters . Accelerate . Why green hydrogen is key to the global energy transition Renewable electricity has a critical role in cleaning up our energy system. Power-to-Hydrogen technologies in a high-RES power system can operate throughout long periods of excess renewable energy by feeding hydrogen into one or more energy sinks (e.g. This was an unconventional assertion to make as little as six mos ago. ‘Green’ hydrogen, i.e. The Renewable Energy Directive establishes an overall policy for the production and promotion of energy from renewable sources in the European Union.
