Delivering carbon negative electricity, heat and hydrogen with BECCS – Comparing the options

Biomass can be converted into a range of different end-products; and when combined with carbon capture storage (CCS), these processes provide negative CO 2 emissions. conversion technologies differ in terms costs, system efficiency value, e.g. services provided, market demand product price. The aim this study is to comparatively assess combination BECCS pathways identify the applications which offer most valuable outcome, i.e. maximum removal at minimum cost, ensuring that resources sustainable biomass are utilised efficiently. Three bioenergy evaluated study: (i) pulverised biomass-fired power plants generate electricity (BECCS), (ii) biomass-fuelled heat (BE-CHP-CCS) both electricity, (iii) biomass-derived hydrogen production CCS (BHCCS). design optimisation supply chain network using Modelling Optimisation Negative Emissions Technology framework for UK (MONET-UK), integrates biogeophysical constraints wide feedstocks. results show indigenous sources remove up 56 Mt /yr from atmosphere without need import biomass. Regardless pathway, Bio-CCS deployment could materially contribute towards meeting national target substantial contribution national-scale energy system. Finally, it was more cost-effective deploy all three (BECCS, BE-CHP-CCS BHCCS) rather than individually. • Indigenous MtCO2 emissions per year. All (electricity, heat, hydrogen) provides UK. It combination, BHCCS. cost-optimal function H , Capital cost savings (e.g. retrofit existing plants) high rates enhance deployment.
