Summary of IRENA's 2013 Report on "Road Transport: The Cost of Renewable Solutions"

The International Renewable Energy Agency's (IRENA) 2013 report on renewable solutions for road transport examines conventional and advanced biofuels, biomethane, and electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). The analysis concludes that, with stronger policy support, these technologies could compete with fossil fuels by 2020.

Key Findings:

Conventional Biofuels:
- Ethanol and biodiesel costs are highly sensitive to feedstock prices. Between 2012 and 2020, costs may increase slightly due to food price trends, though ethanol from sugarcane in Brazil showed some stability.
- Conventional ethanol production costs averaged USD 0.8-1.1/LGE, while biodiesel ranged from USD 1.0 to USD 1.3 per liter of diesel equivalent in 2012.
Advanced Biofuels & Electrification:
- Advanced biofuels (cellulosic ethanol, biodiesel, Fischer-Tropsch) face high initial costs but show strong potential for reduction by 2020 due to scale, efficiency gains, and R&D.
- PHEVs and EVs demonstrate competitiveness in certain markets, with EVs potentially cost-effective by 2030 in some scenarios, though battery costs remain a major factor.
Biomethane:
- Biogas-to-methane technology is mature, though upgrading costs pose barriers. Feedstock-cost reductions through waste utilization can enhance competitiveness.
- By 2020, costs could range from USD 0.55 to USD 0.75/LGE for biomethane from wastes.

Challenges & Policy Importance:

High production costs for advanced solutions, limited deployment scale, and technological risks hinder broader adoption.
Policy support and investments in R&D, infrastructure, and deployment are crucial to unlocking cost reductions by 2020.

Practical Implications: Renewable transport fuels require synergy between technology innovation, supportive policies, and scalable infrastructure to achieve cost parity with fossil fuels.
