Energy 'hidden champion' map: biodiesel leaders — Zhuoyue New Energy, Jiaao Environmental Protection, and Shangao Environment & Energy

Jiaao Environmental Protection — Revenue for the first three quarters of 2025 amounted to RMB 3.005 billion, representing a year-on-year increase of 189.39%; net profit attributable to shareholders was -RMB 0.25 billion, up by 81.14% year-on-year. Shangao Environment & Energy — Revenue for the first three quarters of 2025 totaled RMB 1.036 billion, down 0.499% year-on-year; net profit attributable to shareholders was RMB 0.526 billion, soaring 546.9% year-on-year. The historical development of biodiesel has passed through the following stages: Stage I: Incubation Period (late 19th century–1970s) — This phase remained largely confined to laboratory research, with no large-scale application yet. In 1853, two British scientists, Patrick and J. Duffy, first conducted transesterification between vegetable oil and ethanol, synthesizing fatty acid esters—the chemical precursor to modern biodiesel production. In 1893, German engineer Rudolf Diesel invented the diesel engine. At the 1900 Paris Exposition, he publicly demonstrated an engine powered by peanut oil, proving the feasibility of vegetable oils as fuel. In 1937, Belgian scientist G. Chavanne filed a patent for the 'vegetable oil transesterification' process—the first explicit application of transesterification technology to improve fuel properties of vegetable oils, aimed at addressing energy supply challenges in Africa’s colonial territories. Stage II: Technological and Prototype Establishment (1970s–early 1990s) — The oil crises of the 1970s served as a powerful external catalyst for technological advancement. The two oil shocks drove global oil prices sharply upward, spurring efforts to identify petroleum alternatives. In 1979, South Africa’s state-funded Coal, Oil and Gas Corporation (Sasol) systematically researched transesterification of vegetable oils to produce diesel substitutes and established a small-scale pilot plant. Stage III: Industrialization and Policy-Driven Growth (1990s–2000s) — During this period, environmental protection—particularly climate change mitigation—emerged as a stronger driver than energy security alone. In the 1990s, the European Union and the United States introduced robust supportive policies. Representative measures included mandatory blending mandates requiring fixed proportions of biodiesel in conventional diesel, and tax incentives and subsidies that significantly enhanced the market competitiveness of biodiesel. Stage IV: Diversified Feedstocks and Sustainable Development (late 2000s–2010s) — Early concerns over food-vs-fuel competition intensified, prompting industry-wide shifts toward non-food feedstocks. The 2007–2008 global food price crisis triggered widespread criticism and ethical debates regarding food-based biofuels. The EU Renewable Energy Directive began emphasizing second-generation biodiesel and mandated minimum greenhouse gas emission reduction thresholds for biofuels, encouraging utilization of waste resources. Waste cooking oil and animal fats thus became highly favored feedstocks—producing biodiesel with superior carbon-reduction benefits and zero competition with food supplies. Stage V: Technological Innovation (2010s–present) — This stage focuses on achieving lower costs, higher efficiency, and superior product quality, while exploring disruptive technologies. For example, the commercialization of hydroprocessed biodiesel (also known as renewable diesel). This is not based on transesterification, but rather employs hydrotreating of oils to produce a fuel chemically identical to petroleum diesel.
