as red power generation
serves as a critical bridge in
the energy transition, provid-
ing controllable, eible, and reli-
able energy today, while supporting
the ongoing epansion of renew-
ables. Reducing CO
2
emissions
from these plants, however, remains
important.
Carbon capture, utilisation stor-
age (CCS) is emerging as a key
technology for a low-carbon energy
future. Driven by stricter regulations,
rising CO
2
prices, and corporate cli-
mate pledges, CCS especially in
modular gas engine plants offers a
commercially viable, mature solu-
tion to cut emissions by up to 9 per
cent while ensuring reliable power
supply.
In August, following three years
of construction, a carbon capture
and utilisation project has begun
commercial operations. The ork-
sop plant in Nottinghamshire, ,
is a demonstration of the patented
FlePower Plus
®
concept. Devel-
oped by Landmark Power oldings
(LMP) in collaboration with ic-
tory ill, Rolls-Royce Power Sys-
tems and Asco Carbon Dioide
(Asco) the facility delivers M
of electricity, while producing food-
grade CO
2
for industrial use.
Ralph Spring, CEO, Asco Carbon
Dioide Ltd, noted “Revenue di-
versication is always a key driver
for businesses. As CO
2
pricing rises
and net ero targets tighten, CCS
as a sustainable strategy is a timely
and valuable solution.”
as red power plants with CCS
provide operational eibility, reli-
ability, and geographic adaptability.
They can integrate effectively with
variable renewable generation, stabi-
lising the grid during periods of low
solar or wind output and while green
hydrogen and biomethane are poten-
tial long-term decarbonisation op-
tions, their current availability and
cost limitations make CCS the
only commercially mature solution
capable of delivering immediate re-
ductions in CO
2
emissions from gas
red generation. Additionally, cap-
tured CO
2
is an industrial commodi-
ty with a wide range of applications.
“Carbon dioide can be used in
mineralisation processes for con-
struction materials such as cement
or concrete, in the production of
synthetic fuels, or as a chemical
feedstock, providing an additional
revenue stream beyond electricity
sales,” said Spring. “CO
2
is also wide-
ly used in the food and beverage in-
dustry for eample in carbonated
drinks, refrigeration, and packaging
as well as in other sectors such as
horticulture for greenhouse enrich-
ment and water treatment.”
Forecasts suggest annual new
CCS capacity currently in the
double-digit M range could
reach several hundred M by 2,
totalling gigawatts cumulatively.
Economic drivers include carbon
credit revenues, lower E ETS com-
pliance costs, and infrastructure syn-
ergies (e.g., access to eisting stor-
age in Northern Europe). The
modular, scalable design (from tens
to hundreds of M) enables cost-ef-
fective, eible CO
2
reduction. ith
rising CO
2
prices and supportive
E policies, these plants offer a
compelling near-term investment to
accelerate decarbonisation.
In the , the Net ero Innova-
tion Portfolio (NIP) funds pilot
projects, while the Cluster Sequenc-
ing Model backs regional infrastruc-
ture, fostering coordinated industrial
and energy cluster deployment. New
mechanisms like Dispatchable Pow-
er Agreements (DPAs) and low-
emission electricity incentives aim
to boost project viability and attract
private investment, positioning
CCS plants as reliable mid-merit
assets in the ’s 2 decarboni-
sation strategy. At the E level, the
Innovation Fund supports large-
scale decarbonisation, though target-
ed backing for engine-based CCS
is still developing.
The orksop project integrates
multiple technologies to maimise
energy efciency, combining high-
efciency mtu gas engines, Organic
Rankine Cycle Turbines (ORCs),
and Asco carbon capture modules in
a eible, modular design.
The plant’s power generation is
based on si mtu Series LF-
NER gas engines, selected for their
high efciency, rapid load response,
and reliable performance under
varying grid conditions. Compared
to large gas turbines, gas engines
provide compact, scalable designs
with faster deployment, making
them ideal for small to medium-
sied plants and complementing re-
newables and hydrogen in the tran-
sition to net ero.
These compact, standardised en-
gines are designed for modular,
containerised deployment, which
simplies commissioning and al-
lows eible operation. eat from
the engine jacket water is recovered
by four low-temperature ORCs,
each directly coupled to an individ-
ual engine, to generate additional
electricity.
In future iterations, a ring main
conguration will enable the ORCs
to draw heat collectively. This
means that if one ORC is ofine for
maintenance, the others can in-
crease their output. It also opens the
opportunity to capture heat from ad-
ditional sources, including the car-
bon capture process, further en-
hancing overall plant efciency.
“At the orksop plant, a high-
temperature ORC currently uses e-
haust gas heat to generate additional
electricity. In future projects, this
ehaust heat will be redirected to
produce steam for the CC system,
simplifying operations, enhancing
overall CP (combined heat and
power) efciency, and reducing op-
erating costs,” said Ollie Fergusson,
ead of Project Development,
Landmark Power oldings.
The Asco carbon capture modules
manage the separation, purication,
and liquefaction of CO
2
, with the
plant achieving a total annual CO
2
capture capacity of tons.
The plant layout, shaped by its evo-
lution from a peaking site to a high-
efciency power plant and nally to
a CCS-integrated facility, pro-
vides valuable insights for future
sites. These lessons will allow clos-
er integration of power generation
and CC units, optimising ue gas
routing and CO
2
handling.
Additional benets of the modular
conguration include the ability to
continue operations during mainte-
nance and the ease of replicating
similar plants in other locations. y
combining proven gas engine tech-
nology with ORC heat recovery and
carbon capture, orksop demon-
strates that small-to-medium-scale
plants can deliver tangible environ-
mental and economic benets.
The development of the orksop
plant followed a phased approach,
demonstrating how modular CCS
plants can progress from concept to
full operation. This timeline high-
lights the importance of robust proj-
ect management, eibility, and
close supplier collaboration, partic-
ularly when navigating comple in-
tegrated systems. In parallel, key in-
tellectual property milestones
illustrate the innovative technolo-
gies underpinning the project.

This roadmap showcases how care-
ful planning, adaptability, strong
supplier relationships, and concur-
rent innovation through patented
technologies enable comple proj-
ects to move from planning to suc-
cessful operation, even in the face of
unepected challenges.
Despite the challenges posed by
the EPC contractor’s insolvency, the
project was successfully completed
thanks to strong partnerships with
key suppliers, including Rolls-Royce
Power Systems, Asco, Climeon, and
Turboden. LMP’s direct manage-
ment of contracts allowed the project
to maintain momentum, although
with an unavoidable delay.
The absence of a pre-FEED study
and incomplete EPC design re-
quired on-the-y modications dur-
ing construction, including adjust-
ments to the Turboden hot oil
system, absorberdesorber spray
noles, and the scrubber cooling
system. Future projects will prioritise
complete design packages and de-
tailed construction and commission-
ing schedules prior to construction.
The plant’s modular conguration
allowed operational eibility dur-
ing redesign activities and will con-
tinue to do so during operational
maintenance, reinforcing the value
of eible layouts for both current
operations and future epansion.
These lessons provide a roadmap
for future modular CCS projects,
emphasiing risk mitigation, suppli-
er collaboration, and operational
optimisation.
“Our factory-validated, fast-to-
market modular mtu gas container
solutions align perfectly with As-
co’s epertise in delivering turnkey
carbon capture systems. Together,
under Landmark’s FlePower Plus
concept, we provide maimum ef-
ciency and reliability to meet any
customer requirement,” said Mi-
chael Stipa, Senior ice President

lutions, Rolls-Royce Power Sys-
tems
The planned investment for ork-
sop was approimately . million
per M installed, although costs
were affected by EPC disruptions.
“The project is epected to deliv-
er returns of around 2 per cent,
based on multiple revenue streams,
including electricity sales to the
grid, capacity market contracts, and
CO
2
offtake agreements,” said Mi-
chael Avison, CEO, Landmark
Power oldings. “Private wire
sales to a nearby industrial custom-
er will further enhance the return
on investment.”
The modular design also enables
integration with microgrids and be-
hind-the-meter supply for industrial
clients. The combination of electric-
ity and CO
2
revenues demonstrates
the commercial viability of modular
CCS plants.
The project has strategic signi-
cance and market prospects are
promising.
“The orksop plant’s success val-
idates the potential for eible,
modular gas engine CCS systems
to meet growing demand for low-
emission power in the , Europe,
and the SA,” said Stipa. “Its com-
bination of technical maturity, scal-
able design, and diversied revenue
streams demonstrates that small-to-
medium plants can achieve measur-
able emissions reductions while re-
maining commercially viable, offer-
ing a bridge between intermittent
renewables, grid stability require-
ments, and the decarbonisation of
hard-to-electrify sectors.”
ey market opportunities include
electricity sales (both grid-connect-
ed and private wire) and CO
2
off-
take for industrial, or synthetic fuel
applications. Additional opportuni-
ties include co-locating plants with
industrial users, microgrid solu-
tions, and sustainable aviation fuel
(SAF) production. Rising CO
2
pric-
es, supportive energy policy,
and growing demand for reliable
low-carbon power further strength-
en the commercial case. Together,
these factors position orksop and
future FlePower Plus sites as cor-
nerstones of the energy transition,
delivering both environmental and
commercial value at scale.
