Terrestrial Energy USA, an organization that’s creating a fourth-generation molten salt nuclear reactor, has joined forces with Southern Co. and several other U.S. Department of Energy (DOE) nationwide labs, in a analysis and improvement (R&D) challenge that seeks to pin down whether or not its reactor know-how can produce hydrogen effectively utilizing nuclear warmth and energy. 

The two-year-long challenge will study how effectively and economically Terrestial’s Integral Molten Salt Reactor (IMSR) energy plant can produce industrial-scale hydrogen. It will check a hybrid sulfur course of, which is a carbon-free technique of producing hydrogen from water and “could also be extra environment friendly than high-temperature steam electrolysis,” Terrestrial mentioned in an announcement on September 5. 

Essentially, the challenge “intends to exhibit the industrial and industrial-scale viability of pairing the hybrid sulfur course of with an IMSR energy plant for large-scale manufacturing of hydrogen with zero greenhouse-gas emissions,” it famous. 

The R&D demonstration follows 20 years of analysis on the DOE’s Savannah River National Laboratory (SRNL). Sandia National Laboratories and Idaho National Laboratory will even collaborate on the challenge. 

Hydrogen’s Game-Changing Potential

The use of hydrogen as an power provider has gained great consideration lately owing largely to the aspect’s excessive flexibility. Hydrogen—probably the most ample and lightest of parts—is odorless and unhazardous, and it has the best power content material of widespread fuels by weight, which implies it may be utilized in a full vary of functions, from energy technology to transportation and trade. 

However, it isn’t discovered freely in nature and have to be extracted (produced, or “reformed”) by way of a separate power supply (equivalent to energy, warmth, or mild). The bulk of hydrogen is in the present day produced utilizing fossil power, largely by steam methane reforming of pure fuel. Other widespread hydrogen-producing processes embody partial oxidation and autothermal reforming. 

Several consultants on the World Gas Conference in Washington, D.C., this June famous hydrogen’s rising—and doubtlessly “game-changing”—use for storage of renewable electrical energy (transformed by way of water electrolysis). In that course of, hydrogen could be transformed to energy and energy transformed to hydrogen. Hydrogen might additionally change fossil fuels within the chemical trade, if captured carbon is mixed with the aspect and used as chemical feedstock. Some consultants famous that hydrogen will also be used to impress functions that at present use diesel, and the place batteries aren’t a viable resolution, equivalent to to energy heavy-duty transport—equivalent to non-electrified trains or maritime transport. Others mentioned that hydrogen may be used for decentralized energy manufacturing in a future power system. 

As Terrestial famous on Wednesday, by 2020, the hydrogen market is predicted to succeed in $200 billion. 

The Promise of Molten Salt Reactors 

Interest in molten salt reactor know-how has additionally kicked up of late. Molten salt reactors into consideration for future licensing by the Office of New Reactors, an arm of the U.S. Nuclear Regulatory Commission (NRC), use both strong gas or liquid gas (gas combined with molten salt). The NRC notes that at the least 4 molten-salt reactor designs are below improvement—Flibe Energy’s 600-MWth LFTR (liquid-fluoride thorium reactor), Martingale’s 557-MWth ThorCon, Transatomic Power’s 1,250-MWth TAP (Transatomic Power), and Terrestial’s 400-MWth IMSR. “The thermal spectrum liquid gas reactors use a fluoride salt and a few make use of on-line removing of fission merchandise and presumably actinides. Some have distinctive methods of including fissile and fertile materials,” notes an April 2018 report from Brookhaven National Laboratory’s Nuclear Science and Technology Department.
