Lisbon Locks In a 9.1% Biomethane Quota for 2030 — Government Adds €20M to the €400M PRR Pot, Forty-Two Projects Wait at DGEG and Sixteen Already Have Public Money

Environment and Energy Minister Maria da Graça Carvalho on Friday, 24 April 2026 set the most concrete biomethane target Lisbon has yet committed to: 9.1% of national natural-gas consumption — roughly 2.7 TWh — must come from biomethane by 2030, climbing to 18.6% (5.8 TWh) by 2040. The announcement, made at a Lisbon market session alongside Secretary of State for Energy Jean Barroca, also unlocks an additional €20 million from the latest PRR reprogramming, layered on top of an existing portfolio of more than €400 million earmarked for renewable gases under the Recovery and Resilience Plan.

The Quotas, Sector by Sector

Carvalho confirmed the obligation will be enforced through sectoral incorporation quotas. Industry must blend 1.5% biomethane in 2027, rising to 9% in 2030. Large gas retailers face a softer ramp — 2% in 2028, climbing to 6% by the end of the decade. The transport file is already tighter: renewable fuels in road transport must reach 13% in 2026 and 28% in 2030, a target locked in by the transposition of the EU's revised Renewable Energy Directive.

The headline 9.1% number is the aggregate that emerges when the sectoral quotas are summed and weighted by consumption. It is also the number Brussels will measure Portugal against under its updated National Energy and Climate Plan submission.

Forty-Two Projects, Sixteen Already Funded

The pipeline at the Direção-Geral de Energia e Geologia (DGEG) stands at 42 registered biomethane projects, of which 16 already have public financing committed and the remainder are queueing for prior environmental licensing or grid-injection authorisations. The bottleneck has not been money — it has been licensing speed and grid availability.

The Government's answer is a four-stage licensing guide that consolidates what was previously a scattered set of approvals across DGEG, the regional CCDRs and the Agência Portuguesa do Ambiente. Two new tools were unveiled alongside the targets: a Biomethane Portal for project promoters and a Biomethane Atlas — a geospatial platform built jointly with DGEG and LNEG that maps feedstock potential across continental Portugal at the parish level.

Where the Methane Comes From

Biomethane is chemically identical to natural gas, but it is produced from organic waste — livestock effluent, municipal solid waste, wastewater treatment sludge, and agro-industrial and forestry residues. It can be injected into the existing gas grid without modification, which is why Floene — the operator of Portugal's low- and medium-pressure distribution network — is the critical infrastructure node. Floene has previously reported about 200 active requests to inject biomethane and hydrogen into its grid, a backlog the new licensing guide is meant to clear.

The political logic is straightforward. Portugal imports nearly all of its natural gas, and biomethane is the only renewable molecule that can substitute that gas in industrial processes — ceramics, cement, glass — that cannot economically electrify. The decarbonisation case is reinforced by a strategic-autonomy case: every TWh of biomethane is a TWh that does not have to ship through Sines as LNG.

The Numbers Skeptics Will Watch

The targets are ambitious. Portugal currently produces almost no commercial biomethane — most of the upcoming volume is engineering paper, not steel in the ground. The 2027 industrial quota of 1.5% gives promoters less than two years to commission plants, secure feedstock contracts and complete grid-injection works. The €420M PRR envelope must be deployed before the August 2026 PRR national execution deadline, which means the next four months are when the schedule either holds or breaks.
