Among the arsenal of solutions at humanity's disposal, perennial biomass power stands out as a promising force in the transition towards clean, renewable energy. The utilization of perennial biomass feedstock has the potential to displace fossil fuels, thereby reducing carbon emissions significantly and contributing to a more sustainable future.

Perennial biomass power holds immense promise as a 'bridge' to a renewable energy future, effectively substituting conventional coal, oil, and natural gas for the generation of both heat and electricity. This transformative shift hinges on the exclusive utilization of perennial bioenergy feedstocks and excludes annuals, waste materials, and forest resources. By adhering to these criteria, biomass power presents an opportunity to mitigate 2.62–3.59 gigatons of carbon dioxide equivalent emissions by 2050. This remarkable achievement comes with associated marginal first costs ranging between US$75.81 billion and US$87.23 billion. However, it is imperative to recognize that the viability of biomass power may diminish as flexible grids and clean wind and solar energy, coupled with energy storage solutions, become more accessible in various regions.

Our biomass power solution leverages the use of perennial biomass to produce electricity and heat. This process is based on a carbon cycling principle, where carbon moves from the atmosphere into plants and subsequently returns to the atmosphere. Consequently, biomass energy generates net-zero new emissions, contingent on the establishment and maintenance of a delicate equilibrium. In practice, this solution effectively supersedes conventional electricity-generating technologies, such as coal, oil, and natural gas power plants.

Perennial biomass, constituting plants with lifespans exceeding three years, is a pivotal element in this solution. Research has consistently shown that annual bioenergy crops, like corn, offer negligible advantages over fossil fuels regarding their climate and energy impact. In contrast, perennial grasses, characterized by their natural productivity, lower chemical and water requirements, and non-food crop status, have gained favor as the future of energy farming systems. This estimation is grounded in a comprehensive analysis of data from various sources, attributing 20.2 percent of biomass to perennials.

Our projection for the total addressable market for the Biomass Power solution is founded on anticipated global electricity generation from 2020 to 2050. We derived the figure of 148,912 from comprehensive data encompassing solid biofuels and biogas (IRENA, 2022), supported by the synthesis of information from authoritative sources (El Bassam, 2010; NREL, 2011; Turconi et al., 2013).

Capital and operating costs have been meticulously deduced from peer-reviewed sources, incorporating data from the Drawdown analysis. Our assumptions take into account the average installation cost of US$4,402 per kilowatt, with a learning rate of 8 percent. This learning rate leads to a projected cost of US$3,806 per kilowatt in 2030 and US$3,540 in 2050, as opposed to the weighted average of US$2,322 per kilowatt for conventional fuels like coal, natural gas, and oil. The average capacity factor for biomass stands at 69 percent, a notable improvement compared to the 57 percent achieved by conventional fuels. Operation and maintenance costs, inflation-adjusted from Drawdown, are estimated at US$0.02 per kilowatt-hour, with fixed costs pegged at US$118.82 per kilowatt, compared to US$0.01 and US$45.11, respectively, for conventional fuels. Biomass fuel costs, on average, amount to US$0.02 per kilowatt-hour, a significant reduction in comparison to the weighted average of US$0.06 for conventional fuels.

Net first costs for implementing a medium growth trajectory, derived from the biomass and waste electricity generation projections of IEA (2023) Energy Technology Perspectives 2DS and B2DS scenarios, are projected at US$70.83 billion from 2020 to 2050, with an impressive lifetime savings of US$284.51 billion. In adherence to this scenario, the Biomass Power solution could potentially mitigate 2.62 gigatons of carbon dioxide equivalent greenhouse gas emissions between 2020 and 2050.

It is crucial to recognize that biomass energy operates as a transitional solution. It complements the intermittent nature of wind and solar power until energy storage technology matures, and grid flexibility improves. The management of potential drawbacks associated with biomass energy, such as land use and feedstock sustainability, necessitates vigilant regulation.

While the carbon savings realized from biomass power are commendable, it is essential to acknowledge that the analysis presented here does not account for technologies that incorporate carbon capture and storage. Furthermore, the wide array of electricity-generating technologies and biomass fuels, along with uncertainties regarding the share of perennial crops, introduce significant variability into the equation.

The deployment of perennial biomass power is a pivotal step in our mission to achieve carbon neutrality. This solution, meticulously assessed and founded on robust data, has the potential to substantially reduce carbon emissions while fostering a more sustainable energy future. However, it is imperative that we remain attentive to emerging technologies and regulatory frameworks to harness the full potential of biomass energy in our journey towards a carbon-neutral world.
