BP’s Archaea
Energy just announced the commissioning of its first modular landfill gas-to-renewable
natural gas (RNG) plant. I like to keep track of modular energy developments
since modularity often means efficiency and solutions that tend to work well.
This new plant is in Medora, Indiana, adjacent to a landfill owned by waste
management company Rumpke. Archaea’s proprietary Archaea Modular Design
(AMD)—is equipped to capture and process 3,200 cu ft/min. of landfill biogas
into RNG, according to BP. That equates to 4.6MMCF/day of capturing and processing
power if operating at 100% for 24 hours, which is unlikely since downtime can
be significant. Archaea’s design allows plants to be built on skids with
interchangeable components. They plan to put several more of these modular plants
online this year and increase their LNG production by more than six times by
2030. BPO purchased Archaea Energy in October 2022 for $4.1 billion. Below is an
image from an Archaea investor presentation before BP’s purchase showing
modular components.

RNG is
processed biogas. Biogas can be processed to varying degrees and RNG is the
most processed so that it becomes pipeline quality. It is much more expensive
to produce and process than fossil natural gas due to impurities and difficulty
of capture. Since it is captured from sources being generated into the
atmosphere its capturing is considered to be mitigation of otherwise vented methane.
As of the beginning of 2022 it was estimated by Wood MacKenzie that the U.S.
was producing 212 MMCF/day of RNG. That amounts to just 0.2% of U.S. natural
gas production. Since RNG is captured and considered to serve the function of
mitigating a major greenhouse gas it commands premium prices. Those high prices
are needed to make capturing and processing economical. Through the past few
years to early 2022 RNG pricing averaged from $7 to $25 per MCF while fossil
natural gas averaged from $2.50 to $3.50 per MCF. Thus, the premium above
fossil gas probably averages about 3 to 6 times it. Estimates are that RNG
production will increase by 10 times by 2040, but even then, it probably won’t
make up much more than 1-1.5% total U.S. natural gas production, although some
estimates are as high as 3%. It is desirable as a means of carbon offsetting so
companies will continue to purchase it at premiums for this purpose. State
mandates are also a factor. The EPA periodically sets values for RINs, renewable
energy credits which are traded. Thus, the economics of RNG fluctuate in a
number of ways. Different sources of RNG have different carbon intensities but
also differing costs to produce. For example, RNG made from manure has very low
carbon intensity, much lower than RNG from landfill gas, but is much more
costly to produce.

As the
following graphs show, landfill gas makes up the vast majority of feedstocks
for RNG and that will likely continue to be the case going forward. Other
sources include agriculture & livestock, food waste, and wastewater at
treatment plants. Landfills are a major source of vented methane, producing about
17% of methane emissions according to the EPA. This may be a significant
underestimation according to some sources. Landfills also emit significant
amounts of CO2. Landfill gas is often roughly 50% methane and 40-50% CO2, with
small amounts of other gases, some of them toxic. The high CO2 content makes it
attractive for CCS since the CO2 is already captured and separated. All that is
left is to transport it and sequester it. Archaea is interested in this as well
as using RNG as a feedstock for blue hydrogen where the CO2 from pre-combusted RNG
during steam reforming would be captured and sequestered as well.
