California Revives 19th-Century Biofuel to Battle Climate Change: California is once again showing the world how innovation can drive environmental change. By turning to 19th-century biofuels, the state is stepping up its game to tackle climate change and reduce its dependence on fossil fuels. This may sound like something from the past, but it’s actually a forward-thinking approach to help reduce greenhouse gas emissions and promote a cleaner future. Let’s dive into this fascinating story of how California is breathing new life into biofuels—and how it could reshape the future of energy.
California Revives 19th-Century Biofuel to Battle Climate Change
California is once again proving why it’s a global leader in climate innovation. By embracing 19th-century biofuels, such as renewable natural gas, the state is taking a giant leap toward a sustainable future. With innovative technologies like the Cummins X15N engine and policies like the LCFS, California is not just cleaning up its air—it’s creating jobs, improving public health, and setting a standard for the world to follow. As the RNG industry continues to expand, it’s clear that biofuels have a significant role to play in our collective fight against climate change. By supporting policies that incentivize cleaner fuels and adopting new technologies, we can work together to create a cleaner, greener future for all.

Understanding the Revival of 19th-Century Biofuels
Before we get into the nuts and bolts of California’s ambitious plan to reduce its carbon footprint, let’s first take a step back and understand what biofuels are. In simple terms, biofuels are fuels made from living organisms or organic waste. While fossil fuels (like oil and coal) have been around for centuries, biofuels have a long history too—dating back to the early days of the industrial revolution.
In the 19th century, the idea of using organic matter for fuel wasn’t new. Early versions of biofuels powered early engines and vehicles, but fossil fuels soon took over because they were easier to access and more cost-effective. Fast forward to today, and California is looking to revive biofuels, particularly renewable natural gas (RNG), to help fight climate change.
The Role of RNG in Fighting Climate Change
So, what makes RNG different from regular natural gas? Traditional natural gas is made from fossil fuels like oil and coal, and burning it releases harmful carbon dioxide (CO2) into the atmosphere, contributing to global warming. RNG, however, is made from renewable sources like organic waste, such as food scraps, agricultural waste, and even manure from farms.
When these organic materials break down in landfills, they naturally release methane gas, which is a potent greenhouse gas. However, by capturing this methane and converting it into RNG, we can turn a harmful emission into a clean fuel source. This process can significantly reduce overall greenhouse gas emissions and help fight climate change.
California has long been a leader in environmental policy, and it’s no surprise that the state is leading the charge on RNG. In fact, RNG production is already one of the fastest-growing sectors of California’s renewable energy market. According to the California Air Resources Board, using RNG can reduce the carbon intensity of transportation fuels by up to 100%.
The X15N Engine: A Game-Changer
One of the most exciting developments in California’s RNG revival is the introduction of the Cummins X15N engine, a large natural gas engine designed to run on RNG. This engine offers a clean alternative to traditional diesel engines, which are known for emitting harmful pollutants like nitrogen oxide (NOx) and particulate matter (PM). The X15N, by comparison, emits almost no tailpipe pollution, making it an attractive option for businesses and government fleets.
Companies like UPS and Walmart have already adopted RNG-powered trucks in their fleets. These companies are seeing not only environmental benefits but also economic advantages, as RNG can be more cost-effective than diesel in the long run. By making the switch to RNG, these companies are not only helping to fight climate change but also positioning themselves as leaders in sustainability.
Key Policies Supporting California Revives 19th-Century Biofuel to Battle Climate Change
California’s Low Carbon Fuel Standard (LCFS) has played a significant role in encouraging the use of biofuels like RNG. Since its inception in 2013, the LCFS has required a reduction in the carbon intensity of transportation fuels used in the state. This policy incentivizes the development of low-carbon alternatives, like RNG, by offering credits to producers who meet carbon-reduction goals.
In fact, the LCFS has issued over $22 billion in credits to biofuel producers, with about 80% of those credits going to RNG. This policy has not only spurred innovation but also created a robust market for RNG, helping to develop infrastructure and support its widespread adoption.
However, there is some debate about the cost of this program and its potential impact on fuel prices. Critics argue that the incentives could drive up the cost of fuel, making it more expensive for consumers. But despite these concerns, the long-term benefits of using cleaner fuels—both for the environment and public health—are expected to outweigh the potential costs.
RNG’s Future: A Growing Industry
The future of RNG in California looks promising. Cummins plans to expand RNG production, with 250 plants already operational and another 100 under development. This expansion is essential to meeting the growing demand for RNG-powered vehicles and infrastructure.
RNG is not just a passing trend—it’s becoming a vital part of California’s overall climate strategy. The state’s goal is to achieve carbon neutrality by 2045, and RNG will play a critical role in helping the state reach this target. With a combination of innovation, policy support, and growing infrastructure, RNG could become a cornerstone of California’s fight against climate change.
Expanding RNG Infrastructure and Local Benefits
A significant aspect of California’s RNG revival is the expansion of RNG fueling stations and infrastructure. The state is investing heavily in building a network of public and private RNG fueling stations, making it easier for companies to adopt RNG-powered vehicles.
In addition to the environmental benefits, expanding RNG infrastructure also creates local jobs. From the construction of fueling stations to the operation of RNG plants, the growth of this sector provides economic opportunities in both rural and urban areas of California. The development of RNG infrastructure helps stimulate local economies, benefiting communities that have been traditionally reliant on fossil fuel industries.
How California’s RNG Revival is a Global Model
California has always been at the forefront of environmental innovation, and its push for RNG can set an example for other states and countries. As global leaders in sustainability, California’s example of integrating historical biofuel technology with modern innovations is a blueprint for the world. Other regions facing similar climate challenges can learn from California’s commitment to renewable energy and green technology.
Countries with large agricultural industries, like Brazil, India, and China, could benefit from a similar focus on RNG. By capturing the methane released from agricultural waste, these countries could significantly reduce their greenhouse gas emissions while fostering clean energy growth.
Practical Advice: How Can You Get Involved?
If you’re in California, or anywhere else looking to support clean energy, here are some practical ways to get involved:
- Adopt RNG in Your Fleet: If you’re a business owner with a fleet of vehicles, consider making the switch to RNG-powered trucks. Not only will you reduce your carbon footprint, but you may also qualify for financial incentives through California’s LCFS program.
- Support Biofuel Legislation: Advocate for policies that support the growth of the biofuel industry. Support bills that incentivize the production of renewable fuels like RNG, and push for more funding for infrastructure development.
- Invest in RNG Infrastructure: If you’re an investor or part of a company that supports renewable energy, look into funding projects that develop RNG production plants or fueling stations.
- Stay Informed: Keep up with developments in the biofuel industry. Follow organizations like the California Air Resources Board and Renewable Natural Gas Coalition to stay updated on policies, projects, and opportunities in RNG.
