Energy efficiency and renewable energy firm Ameresco has completed its McCarty Road landfill gas-to-RNG plant in Houston, Texas.
Developed with Republic Services and U.S. Gain, the facility has a gross installed capacity of more than 1.1 million Dekatherms (1.099 British thermal units) per year and is capable of processing 4,500 standard cubic feet per metre of raw landfill gas.
Ameresco broke ground on the project in the second quarter of 2020 and reached ‘mechanical completion’ in early December while navigating the construction challenges and equipment delays associated with the pandemic and an active hurricane season.
“We are proud of this innovative partnership because it allows us to utilise a natural by-product of the landfill to create low-carbon transportation fuels and other forms of renewable energy,” said Pete Keller, vice-president of recycling and sustainability at Republic Services, which owns and operates McCarty Road Landfill.
“Last year, Republic Service set a long-term sustainability goal to send 50% more landfill gas to beneficial reuse by 2030. This project not only creates additional clean energy resources in the regional economy but also reduces greenhouse gas emissions and helps us meet that goal.”
This long-term, collaborative partnership will result in a reduction of more than 61,000 tons of CO2, equivalent to removing 103,000 passenger cars from the roads.
Ameresco’s executive vice-president, Mike Bakas, said: “This complex RNG facility was swiftly constructed amid incredibly challenging conditions due to the steadfast execution by the dedicated, on-site Ameresco team and our project partners.
“By leveraging advanced technologies to transform the raw feedstock into a readily available renewable fuel source, clean energy can be made available to further reduce our country’s reliance on fossil fuel. We are fortunate to have partnered with Republic Services on a project that amplifies the green energy infrastructure of the future.”
“As a leading distributor of sustainable energy solutions, we’re honoured to work with Ameresco on the McCarty Road Landfill project, taking gas produced to some of the most forward-thinking organisations throughout the nation,” said Mike Koel, president of U.S. Gain.
“Demand for RNG from the transport sector has steadily risen for the past several years and we anticipate this to continue into the future because of the positive impact it offers.
“Organisations using RNG reduce transport-related emissions in support of sustainability goals and lower fuel spend thanks to economic benefits like environmental and tax credits. Despite challenges experienced in 2020, we applaud Ameresco on the progress of this landfill project and look forward to future collaboration.”
The project is expected to be operational in early 2021.
