Since the low-carbon technology fusion energy is scheduled to be commercialized beyond 2050, the late-mover needs to flexibly and strategically operate for sustainable cash flow responding to the future market mechanism. Carbon sequestration of the fusion–biomass hybrid system by using low-temperature heat is proposed under the two preconditions: the establishment of the deregulated electricity market, and the emission trading market. When the price is above the breakeven price, the hybrid system generates electricity; otherwise, charcoal production is performed. Charcoal production is a stable solid form of carbon capture, and can possibly be traded on the emission credit market to secure profit. The experimental result shows that it is possible to produce charcoal at low temperature of 280 °C, indicating that any type of blanket design is applicable in the hybrid system concept. The carbon sequestration cost is 39 $/tCO 2 at the default parameter of net electric output of 4000 $/kW e for the fusion power plant, and 60% of charcoal yield from experimental result. Comparison between the hybrid system and the fusion power plant proves that the fusion–biomass hybrid system prevents further loss, by setting two-track income structures in the various market mechanisms.

未来市场机制中融合-生物质混合系统脱碳策略的经济分析

由于低碳技术聚变能源计划在2050年以后实现商业化,后发者需要灵活、战略性地运作,以应对未来市场机制的可持续现金流。在两个前提下提出了利用低温热的聚变-生物质混合系统固碳:建立放松管制的电力市场和排放交易市场。当价格高于盈亏平衡价格时,混合动力系统发电;否则,进行木炭生产。木炭生产是一种稳定的固体碳捕获形式,可以在排放信用市场上进行交易以确保利润。实验结果表明,可以在280℃的低温下生产木炭,表明任何类型的毯子设计都适用于混合系统概念。在聚变电厂净电力输出为 4000 美元/kW e 的默认参数下,碳封存成本为 39 美元/tCO 2 ,​​实验结果为木炭产量的 60%。混合动力系统和聚变电厂之间的比较证明,聚变-生物质混合动力系统通过在各种市场机制中设置双轨收入结构来防止进一步损失。
