October 09, 2025 [Storage Terminals Magazine]- Global momentum behind CCS is accelerating, with over 500 projects now in development worldwide, up fivefold in just five years, according to the Global CCS Institute. Operational capacity has already passed 50 million tonnes per year and is projected to reach around 430 million tonnes by 2030, according to the International Energy Agency.
As industry investment ramps up, the ability to rapidly identify and mature viable storage sites has become a critical competitive advantage. To help meet this demand, Belltree, a leader in subsurface intelligence, and Earlsfield Energy, a fast-growing CCS and low-carbon energy developer, have formed a strategic partnership — formalised through a Memorandum of Understanding — aimed at combining Belltree’s technical evaluation strengths with Earlsfield’s development expertise to accelerate the screening of potential projects.
This partnership brings together Belltree’s advanced digital evaluation technology and Earlsfield Energy’s project development and operational expertise. Earlsfield is committed to balancing economic and environmental goals, developing sustainable infrastructure, and achieving carbon-negative outcomes through scale, discipline, and reliability. Earlsfield brings end-to-end delivery capability, taking screened opportunities through permitting, development and long-term operations.
“Smart deployment of Belltree’s digital platform brings a new dimension to Earlsfield Energy’s strategy to acquire, build and operate assets in the gas production sector and the carbon storage space,” said Pierre Girard, CEO at Earlsfield Energy. “We are looking forward to a phase of co-creation of new products and workflows.”
“This agreement represents an important step for Belltree as we extend the reach of our digital evaluation platform,” said Grant Stewart, business development director at Belltree. “Our bMark™ CCS platform enables fast, data-driven assessment of storage potential. Combined with Earlsfield’s delivery expertise, we can progress high-quality opportunities through comprehensive technical evaluation to fully investable decisions.”
Supporting the Net Zero Agenda
At the centre of the collaboration is bMark™ CCS, Belltree’s benchmarking and screening tool designed to assess subsurface storage potential efficiently, systematically and with regulatory readiness in mind. Earlsfield will integrate this capability into its project screening process to strengthen portfolio growth, with a focus on technically grounded, low-emissions solutions.
The partnership will drive joint technical studies, digital product development and workflow innovation, with the aim of advancing selected opportunities to full technical and commercial readiness as investment-ready projects, supported by robust digital evaluation.
Belltree and Earlsfield Energy welcome collaboration with partners and investors seeking to accelerate CCS development, combining advanced digital screening with scalable workflows that can enable and de-risk future low-carbon investments.
