The facility will use the steam methane reforming method to break natural gas into hydrogen and carbon dioxide which will be captured and stored permanently. Notably, hydrogen is considered clean when produced from natural gas.
The facility, which is expected to become a major supplier of alternative fuels for the marine shipping industry, fits with the Norwegian government's strategy to develop hydrogen and create long-term value from the country's energy resources.
"Hydrogen will play a vital role to accelerate decarbonisation. It has the potential to close as much as 50 percent of the gap in CO2 emissions required to achieve the 2-degree scenario, by replacing fossil feed-stock and fuel through clean hydrogen and ammonia production and thus reducing the carbon footprint of industrial companies and in the shipping sector", according to the Aker Clean Hysdrogen website.

Green hydrogen is produced by using renewable energy -- such as combining wave energy with solar -- to power electrolysis that splits water into its constituent parts. It is regarded as a leading approach in the journey to decarbonise emission-intensive industries and transport sectors. A $2/kg price is widely believed to represent a potential tipping point that will make green hydrogen and its derivative fuels the energy source of choice across multiple sectors, which includes steel manufacturing, fertilizer production, power generation, and shipping where vast near-term demand exists across Europe and internationally.
Green ammonia, a derivative of green hydrogen, is also being assessed as a way to displace fossil fuels in thermal power generation, greatly decreasing the emissions intensity of existing energy infrastructure.
The growth in green hydrogen production using wave energy could potentially be a cost-effective solution in reaching the world's latest hydrogen goals, according to the AW-Energy release.

Nine projects will focus on thermal energy storage, including mature options such as molten salt that can offer near-term deployment opportunities.
Energy storage technologies will be integrated with a range of fossil assets, including coal power plants, natural gas combined cycles, and combustion turbines. Applications include power generation utilities, petrochemical complexes, microgrids, university campuses, and repowering retired coal power plants. Many of the applications are envisioned to include fuel switching (hydrogen or ammonia) or carbon capture and storage to mitigate carbon emissions and leverage the energy storage technology to increase flexibility, reduce cycling damage, and time-shift energy to enhance grid support and asset utilisation.

It can also be used in power generation and can be burned on its own or blended with natural gas to heat residential and commercial buildings or provide high-grade heat for industrial processes. Hydrogen is also commonly used as feedstock for industrial processes such as petroleum refining, bitumen upgrading and the production of ammonia, methanol and steel.

Many biorefineries consume one, or sometimes two, feedstocks grown and harvested nearby. The feedstock contains lignocellulose. That chemical is processed and fermented into biofuels or bioproducts. Accepting a variety of feedstocks could improve the refinery's environmental footprint, economics, and logistics. The team's study showed that a lignocellulosic refinery could be relatively agnostic in terms of the feedstocks used.
Refineries to convert biomass into fuels often rely on just one feedstock. If the refineries could accept more than one feedstock, it would greatly benefit refinery operation. Scientists investigated how five different feedstocks affected process and field-scale ethanol yields. Two annual crops (corn stover and energy sorghum) and three perennial crops (switchgrass, miscanthus, and restored prairie) were pretreated using ammonia fiber expansion, hydrolyzed, and fermented separately using yeast or bacteria.
Researchers found that both biomass quality and biomass yield affected the amount of ethanol each acre produces. However, the effect differed. Biomass quality was the main driver for the ethanol yields for high-yielding crops, such as switchgrass. Biomass yield was the main driver for the ethanol yields for low-productivity crops, such as corn stover. Therefore, to increase ethanol yield for high-yielding crops, focusing efforts on improving biomass quality or conversion efficiency may be prudent.
For low-yielding crops, focusing on increasing biomass yield may be the best strategy. When measuring the amount of ethanol produced during fermentation, most feedstocks fell within a similar range, especially when scientists used bacteria to ferment the biomass. In total, the results of this study suggest that a lignocellulosic refinery may use a variety of feedstocks with a range of quality without a major negative impact on field-scale ethanol yields.
