NEWPORT BEACH, Calif.--(BUSINESS WIRE)--Sep 16, 2025--
Clean Energy Fuels Corp. (NASDAQ: CLNE ) has announced it has broken ground on three renewable natural gas (RNG) production facilities under its development agreement with Maas Energy Works. These projects span six dairies located in South Dakota, Georgia, Florida and New Mexico, and are expected to produce approximately three million gallons of RNG annually once fully operational.

Capturing methane from a combined herd of 24,300 dairy cows, preventing harmful emissions from entering the atmosphere, the RNG produced will be used to power heavy-duty trucking, transit and vocational fleets nationwide – providing a reliable supply of negative-carbon fuel to Clean Energy’s network of over 600 stations.
“Partnering with an industry leader like Maas Energy Works on these projects will enable us to quickly bring meaningful volumes of ultraclean fuel to the transportation market,” said Clay Corbus, senior vice president of renewables at Clean Energy. “We’re seeing rising demand for RNG from fleets looking to decarbonize, and breaking ground on these production facilities is a significant step forward in meeting that need.”
Maas Energy Works brings a unique approach to RNG production through its covered lagoon system. Unlike traditional anaerobic digester tanks which are more costly to build and operate, Maas Energy’s method involves capturing methane from manure stored in large, tarp covered lagoon digesters. This technique offers a cost-effective and efficient alternative for manure collection and RNG production.
Clean Energy has elected to move forward with three RNG projects with Maas Energy Works after finalizing diligence. All demonstrating strong economic viability, the projects are forecasted to cost $80 million and are on track for completion in 2026.
Clean Energy still has the rights to develop the other remaining projects at a later date as market conditions and project economics evolve.
Agriculture accounts for nearly 10 percent of U.S. GHG emissions and the transportation sector accounts for another 28%, according to the U.S. Environmental Protection Agency. Capturing methane from farm waste lowers these emissions. RNG, produced by that captured methane and used as a transportation fuel, significantly lowers GHG emissions on a lifecycle basis when compared to diesel. This allows RNG to be one of the only fuels to receive a negative carbon-intensity score based on the reduction of emissions at the source and at the vehicle.

NUUK, Greenland (AP) — Troops from several European countries continued to arrive in Greenland on Thursday in a show of support for Denmark as talks between representatives of Denmark, Greenland and the U.S. highlighted “fundamental disagreement” over the future of the Arctic island.
Denmark announced it would increase its military presence in Greenland on Wednesday as foreign ministers from Denmark and Greenland were preparing to meet with White House representatives in Washington. Several European partners — including France, Germany, the U.K., Norway, Sweden and the Netherlands — started sending symbolic numbers of troops already on Wednesday or promised to do so in the following days.
The troop movements were intended to portray unity among Europeans and send a signal to President Donald Trump that an American takeover of Greenland is not necessary as NATO together can safeguard the security of the Arctic region amid rising Russian and Chinese interest.
“The first French military elements are already en route” and “others will follow,” French President Emmanuel Macron announced Wednesday, as French authorities said about 15 soldiers from the mountain infantry unit were already in Nuuk for a military exercise.
Germany will deploy a reconnaissance team of 13 personnel to Greenland on Thursday, the Defense Ministry said.
On Thursday, Danish Defense Minister Troels Lund Poulsen said the intention was “to establish a more permanent military presence with a larger Danish contribution,” according to Danish broadcaster DR. He said soldiers from several NATO countries will be in Greenland on a rotation system.
Danish Foreign Minister Lars Løkke Rasmussen, flanked by his Greenlandic counterpart Vivian Motzfeldt, said Wednesday that a “fundamental disagreement” over Greenland remains with Trump after they held highly anticipated talks at the White House with Vice President JD Vance and Secretary of State Marco Rubio.
Rasmussen added that it remains “clear that the president has this wish of conquering over Greenland” but that dialogue with the U.S. would continue at a high level over the following weeks.
Inhabitants of Greenland and Denmark reacted with anxiety but also some relief that negotiations with the U.S. would go on and European support was becoming visible.
Greenland's Prime Minister Jens-Frederik Nielsen welcomed the continuation of “dialogue and diplomacy.”
“Greenland is not for sale,” he said Thursday. “Greenland does not want to be owned by the United States. Greenland does not want to be governed from the United States. Greenland does not want to be part of the United States.”
In Greenland’s capital, Nuuk, local residents told The Associated Press they were glad the first meeting between Greenlandic, Danish and American officials had taken place but suggested it left more questions than answers.
Several people said they viewed Denmark’s decision to send more troops, and promises of support from other NATO allies, as protection against possible U.S. military action. But European military officials have not suggested the goal is to deter a U.S. move against the island.
Maya Martinsen, 21, said it was “comforting to know that the Nordic countries are sending reinforcements” because Greenland is a part of Denmark and NATO.
The dispute, she said, is not about “national security” but rather about “the oils and minerals that we have that are untouched.”
On Wednesday, Poulsen announced a stepped-up military presence in the Arctic “in close cooperation with our allies,” calling it a necessity in a security environment in which “no one can predict what will happen tomorrow.”
“This means that from today and in the coming time there will be an increased military presence in and around Greenland of aircraft, ships and soldiers, including from other NATO allies,” Poulsen said.
Asked whether the European troop movements were coordinated with NATO or what role the U.S.-led military alliance might play in the exercises, NATO referred all questions to the Danish authorities. However, NATO is currently studying ways to bolster security in the Arctic.
The Russian embassy in Brussels on Thursday lambasted what it called the West's “bellicose plans” in response to “phantom threats that they generate themselves”. It said the planned military actions were part of an “anti-Russian and anti-Chinese agenda” by NATO.
“Russia has consistently maintained that the Arctic should remain a territory of peace, dialogue and equal cooperation," the embassy said.
Rasmussen announced the creation of a working group with the Americans to discuss ways to work through differences.
“The group, in our view, should focus on how to address the American security concerns, while at the same time respecting the red lines of the Kingdom of Denmark,” he said.
Commenting on the outcome of the Washington meeting on Thursday, Poulsen said the working group was “better than no working group” and “a step in the right direction.” He added nevertheless that the dialogue with the U.S. did not mean “the danger has passed.”
Speaking on Thursday, Danish Prime Minister Mette Frederiksen said the American ambition to take over Greenland remains intact despite the Washington meeting, but she welcomed the creation of the working group.
The most important thing for Greenlanders is that they were directly represented at the meeting in the White House and that “the diplomatic dialogue has begun now,” Juno Berthelsen, a lawmaker for the pro-independence Naleraq opposition party, told AP.
A relationship with the U.S. is beneficial for Greenlanders and Americans and is “vital to the security and stability of the Arctic and the Western Alliance,” Berthelsen said. He suggested the U.S. could be involved in the creation of a coastguard for Greenland, providing funding and creating jobs for local people who can help to patrol the Arctic.
Line McGee, 38, from Copenhagen, told AP that she was glad to see some diplomatic progress. “I don’t think the threat has gone away,” she said. “But I feel slightly better than I did yesterday.”
Trump, in his Oval Office meeting with reporters, said: “We’ll see how it all works out. I think something will work out.”
