Summary The hydrogen production over the combination of nuclear fusion and biomass conversion technologies achieves the carbon‐negative effect by employing carbon capture and storage technology. Techno‐economic analysis on the fusion‐biomass hybrid system is performed to understand the hydrogen cost and the cost competitiveness as compared to other existing technologies. Cellulose, hemicellulose, and lignin for biomass are chosen for the techno‐economic analysis in addition to the municipal solid waste as another feedstock. Stoichiometric calculation for biomass conversion to hydrogen is employed. Nuclear fusion thermal heat capacity and its heat cost are selected based on literature survey. Gasification plant for hydrogen production is assumed to employ the bubbling fluidized bed gasifier, fed by 20.6 MJ/kg of biomass. The result shows that total syngas capacity is 203 PJ and 137 PJ of hydrogen is produced through a ceramic membrane for H2 separation. The levelized cost of hydrogen is $2.45/kg and the estimated 90% confidence interval of the LCOH ranges from $1.87 to $3.24/kg. The LCOH locates at a competitive position among the existing technologies. The LCOH can further decreased with the development of carbon pricing by the time of fusion commercialization in 2050.

“…The study considered k peak = 1 instead of conventional peaking factors k peak ⩾ 1 linked to modular non planar stellarator coils with large toroidal excursions [8,19,20], due to the assumed patterned wide HTS coil architecture combined with current developments of coil winding surface optimization which have been shown to allow for reduced magnetic field peaking factors [7,59]. Appendix A investigates increased peaking factors k peak = 1, 1.2, and 1.5 as seen in modular nonplanar stellarator coils.…”

“…A single heating system was considered in this analysis for simplification although electron cyclotron heating (ECH) could also be used in conjunction with NNBI, provided that gyrotrons of sufficiently high power and frequency can be developed to operate in high magnetic field environments (10 T and above) [70]. Other heating systems such as ion cyclotron heating (ICH), heating by lower hybrid (LH) waves, or helicon heating were not considered due to the complex plasma boundary shape of stellarators, the reduced need for current drive, or their lower technology readiness level [8,19,71,72].…”

“…It also isolates trends, regions of interest in the design space and principal design parameters affecting the cost of the reactor and cost of electricity (COE). This will serve as a basis for further, 3D studies and refinements in a smaller parameter-space by system-design codes such as PROCESS [4,21], TREND [22], BLUEPRINT [23] or ASC [19]. Due to the limits of 0D analyses and the technological assumptions, absolute estimates are therefore only indicative, but relative arguments are reliable, e.g.…”

High Temperature Superconductors expand the design space of stellarator power-plants toward high magnetic fields B, enabling compact major radii $R$. The present paper scans the space of B, R and other design parameters, finding solutions that are promising from a physics and engineering standpoint, while minimizing the capital cost of the power-plant and the levelized cost of fusion electricity. Similarly, it identifies minimum-cost design points for next-step burning plasma stellarator experiments of fusion gain 1 < Q < 10. The study assumes advanced stellarator configurations of reduced aspect ratio, heated by Neutral Beam Injection. Plasma-facing, flowing liquid metal walls protect it from high heat and neutron fluxes. The study relies on analytical first-principle calculations, and established zero-dimensional empirical scaling laws. Power flows are illustrated by Sankey diagrams. Plasma operating contours are used to determine the reactor’s start-up path. Sensitivity analyses are conducted to identify the most critical reactor parameters within physics, engineering and costing, quantifying their influence on the economics of the power plants. Such 0D study suggests that the assumed next generation HTS, flowing liquid metal walls, and advances in compact plasma configurations could lead to an ignited stellarator power-plant of aspect ratio A ~ 4, R ≤ 4 m, B > 9 T, and normalized plasma pressure β ~ 5 % would minimize both the cost of electricity and capital cost while achieving a net electric power of about 1 GW.
