White Summit Capital has agreed to buy a majority stake in Ferbgas Renewable, a Lisbon biomethane developer. The deal is described as making White Summit a key independent player in Portugal's emerging biomethane industry. Ferbgas does not yet have a plant in operation. What White Summit is buying is a pipeline, a team, and a large bill still to be paid.
Key takeaways
- White Summit Capital announced on 20 May 2024 that it had agreed to acquire a majority stake in Ferbgas Renewable, a Portugal-based biomethane producer founded in 2019 and headquartered in Lisbon, for an undisclosed price.
- Ferbgas Renewable holds a biomethane project pipeline expected to produce about 500 GWh a year, or about 1,706,071 MMBtu, with the first two projects expected to start operating by 2026.
- The Ferbgas Renewable pipeline requires about $217.3 million of investment, and Ferbgas plans to fund up to 100 percent of project capex with White Summit Capital's support.
- Ferbgas Renewable's planned production represents about 15 percent of Portugal's estimated biomethane production by 2030 and is expected to lower Portugal's emissions by about 100,000 tonnes of CO2 by reducing natural gas consumption.
- The White Summit Capital and Ferbgas Renewable deal is the only Portuguese bio-fuel M&A transaction among 31 European bio-fuel deals Enerdatics recorded in 2024.
What is biomethane, and what does Ferbgas do?
Biomethane is gas produced from organic material such as farm waste, food waste or manure, then cleaned until it matches the quality of natural gas. Once upgraded, it can be injected into the ordinary gas grid and burned in the same boilers and industrial plants. Output is measured in energy per year, so a 500 GWh pipeline means plants that together produce about that much gas energy annually.
Ferbgas covers the whole production cycle: finding sites and feedstock, developing and building plants, and then operating and maintaining them. It works on both greenfield sites, built from scratch, and brownfield sites, where existing facilities are adapted. That matters for a buyer, because a biomethane business depends on local feedstock contracts as much as on engineering. Owning the team that secures those contracts is as valuable as owning any single plant.
What is White Summit actually buying?
A development platform at an early stage. Leap classes the deal as early-stage, with the assets under development, and the first two projects are not expected to operate until 2026. There is no production yet to value, which may be one reason the price was not disclosed.
The more telling number is the cost of building what Ferbgas plans. The pipeline needs about $217.3 million of investment for about 500 GWh a year of output. That is roughly $0.43 million of capital per GWh of annual production. Ferbgas intends to fund up to all of that capex itself, backed by White Summit, rather than bringing in co-investors at project level. In effect, the majority stake is a commitment to finance a build programme whose cost has been disclosed even though the share price has not.
Leap also links the deal to White Summit's January 2024 fundraising record, in which the European Investment Fund committed $164.12 million to White Summit's Decarbonisation Infrastructure Fund II. That fund has a target size of $547 million and plans to invest in about ten companies. Biomethane sits within its decarbonisation of industries theme, alongside earlier White Summit investments in Senda, Rainergy and Zunder. Ferbgas fits that pattern of backing mid-market platforms, though the deal record does not state which White Summit vehicle made the acquisition.
How does the build cost compare with other biomethane deals?
It sits in the range of what Leap shows for Iberian and Dutch plants. Genia Bioenergy, in which Repsol agreed to take 40 percent the month before, began building a plant in Tortosa and Campredo in Catalonia with a direct investment of $16 million for 93 GWh a year, about $0.17 million per GWh. Genia's second Salamanca plant, at Machacon, carries an investment of $27 million for about 70 GWh a year, about $0.39 million per GWh. Enerdatics has covered Repsol's 40 percent stake in Genia in detail.
On the acquisition side, ENGIE bought two operating Dutch plants in April 2024 with about 137 GWh a year of combined capacity, for which Leap records a value of $67 million, about $0.49 million per GWh. Enerdatics looked at the expansion headroom built into ENGIE's Dutch biomethane purchase.
Ferbgas' planned $0.43 million per GWh sits between Genia's two plants and below what ENGIE paid for running capacity. The comparison is loose, because build costs vary with plant size, feedstock and grid connection, and a purchase price includes a premium for production that already exists. But it suggests the Ferbgas budget is neither an outlier nor obviously optimistic.
Enerdatics records 31 bio-fuel M&A transactions in Europe announced in 2024, and only nine carry a disclosed value. White Summit's purchase of Ferbgas is the only one of the 31 in Portugal. Most of the activity sits in Spain, Italy and the UK, where buyers including Repsol, Verdalia Bioenergy, Future Biogas and RWE were active.
What does the deal signal for Portuguese biomethane?
It signals that Portugal's biomethane market is still at the stage where a single platform can account for a large share of the national estimate. If Ferbgas' 500 GWh a year is about 15 percent of the country's estimated 2030 production, the implied national figure is around 3.3 TWh. One developer's pipeline is a meaningful part of that.
It also signals what kind of investor moves first in a young market. Utilities and oil majors have bought operating plants and established developers in Spain, the Netherlands and the UK. In Portugal, the first recorded move comes from a mid-market infrastructure fund willing to fund construction from the ground up. That carries more development risk, and the reward is an early position in a market with few established players.
For anyone watching the Iberian biomethane market, the key questions now are execution and offtake. The record does not say who will buy Ferbgas' gas or on what terms. Until the first two plants are running in 2026, the platform's value rests on its pipeline and on White Summit's willingness to fund it.
