10 US BUSINESS NEWS / 2019 Business Elite Awards , Dairy Renewable Natural Gas Producer Announces Expansion of California Facility RNG is already helping eliminate emissions from trucks and buses. Over the last five years, RNG use as a transportation fuel has increased 577 percent, helping displace over seven million tons of carbon dioxide equivalent (how GHG emissions are measured). That’s equal to the emissions from more than a million homes’ electricity use for one year. Research shows that replacing about 20 percent of California’s traditional natural gas supply with RNG would lower emissions equal to retrofitting every building in the state to run on electric only energy and at a fraction of the cost. Using RNG in buildings can be two to three times less expen- sive than any all-electric strategy and does not require families or businesses to purchase new appliances or take on costly construction projects. In recent years, energy providers across the country and around the world are capturing meth- ane emissions—from farms, wastewater treatment plants, and landfills—to create renewable energy that displaces traditional natural gas. For example: • Dominion Energy and Van- guard Renewables recently announced a $200 million Calgren Dairy Fuels and Southern Cali- fornia Gas Co. (So- CalGas) announced that four additional Central Valley dairies have started sending methane produced from cow ma- nure to Calgren’s biogas operation in Pixley, where it is processed into high-quality, renewable nat- ural gas (RNG) and injected into SoCalGas’ system. The Calgren facility now collects methane— a potent greenhouse gas that would otherwise escape to the atmos- phere and contribute to climate change—from more than 66,000 cows at 10 area dairy farms. The additional dairies are projected to nearly double the amount of RNG produced at the facility, further re- ducing greenhouse gas emissions and displacing more traditional natural gas. Calgren partnered with Maas Energy Works to develop these four new dairy digesters as well as the previous six dairy digesters that have been operating since 2018. “Over the last five years, re- newable natural gas use in the transportation sector has grown by almost 600 percent,” said Sharon Tomkins, SoCalGas vice president and chief environmen- tal officer. “We’re looking to build on that success by delivering Growing supplies of renewable natural gas key to reducing emissions from trucks and buildings. Experts estimate that 4,450 Trillion Btus of renewable natural gas will be available by 2040, about 90%of the nation’s current natural gas consumption. more renewable energy options to our customers, including renewable natural gas pro- duced at farms, hydrogen made from surplus solar energy, and advanced fuel cell systems that can provide energy in extreme weather events. Each of these technologies will be essential to promoting the long-term reliability of our energy systems and to meeting California’s ambitious climate goals affordably.” “Calgren is leading efforts in California on this front, working with both dairies and SoCalGas to mitigate emissions,” said Lyle Schlyer, president of Calgren Renewable Fuels. “This facility alone will eventually capture methane produced from the ma- nure of more than 75,000 cows, preventing about 130,000 tons of greenhouse gas emissions from entering the atmosphere each year, the equivalent of taking more than 25,000 passenger cars off the road annually.” Renewable natural gas can rapidly cut greenhouse gas emis- sions (GHGs) because it takes more climate pollution out of the air than it emits as an energy source. The RNG produced at Calgren’s facility today is used as a carbon-negative fuel for heavy-duty vehicles like transit buses and long-haul trucks. RNG can also be delivered to custom- ers to generate clean electricity and heat homes and businesses. Last year, SoCalGas committed to delivering 20 percent of the natural gas it buys for homes and businesses from renewable sources by 2030. More than 80 percent of all methane emissions in California come from organic sources like wastewater treatment plants, landfills, food and green waste and farms. In California, a 2016 law requires a 40 percent reduc- tion of methane emissions from waste sources such as landfills and dairies, with provisions to deliver that energy to customers. The law is expected to bolster the supply of RNG that is already growing rapidly as cities and towns across the country look to divert organic waste from land- fills. Scientists at the University of California, Davis estimate that the state’s existing waste could produce enough RNG to meet the needs of 2.3 million homes. Na- tionally, a just-released study by ICF estimates that 4,450 Trillion Btus of renewable natural gas will be available by 2040, about 90% of the nation’s current residential natural gas consumption.
