Gastech 2023 — LNG supply security, hydrogen, and the energy transition in Milan
Gastech 2023 convened in Milan eighteen months after Europe's energy crisis forced a rapid pivot to LNG. With new European regasification terminals still ramping up and global LNG supply tight, the central question was whether the world could build enough liquefaction capacity to prevent a repeat — and whether long-term gas contracts were compatible with net-zero commitments.
LNG as bridge fuel: the post-Ukraine calculus
By September 2023 Europe had largely solved its immediate gas supply crisis by contracting record volumes of US and Qatari LNG and filling storage to over 90 % ahead of winter. But the cost had been enormous: European industrial gas prices averaged five to eight times pre-crisis levels during winter 2022/23, triggering the largest gas-to-oil switching event since the 1970s oil shocks. That switching — energy-intensive industries and power plants burning fuel oil rather than expensive gas — directly elevated diesel crack spreads and contributed to record European diesel prices in 2022.
At Gastech 2023, European utilities and government delegates were clear: the continent needed 10–15 years of LNG import capacity as insurance, regardless of climate policy. This created a direct tension with the IEA's Net Zero by 2050 roadmap, which calls for no new fossil fuel supply projects beyond those already approved. The debate about whether LNG is a bridge or a lock-in dominated the opening sessions.

The new supply pipeline
The Gastech floor reflected a surge of new project announcements driven by the European demand signal. US Gulf Coast projects dominated: Venture Global, NextDecade's Rio Grande LNG, Sempra's Port Arthur LNG, and expansions at Sabine Pass and Corpus Christi were all prominently featured. Qatar's North Field expansion — adding 48 million tonnes per annum (mtpa) by 2026–2027 — was the single largest supply story, with QatarEnergy signing long-term agreements with European and Asian buyers in back-to-back announcements.
Critics at the conference, including representatives from the IEA and several European climate NGOs, warned that the combined new capacity — roughly 200 mtpa of announced US and Qatari projects — would materially overshoot demand under a 1.5 °C scenario, risking stranded assets and locking in decades of methane emissions. Proponents countered that Asian demand growth, particularly from China, India, and Southeast Asia, justified long-term contracts well into the 2040s.
Hydrogen: blue vs green economics
Hydrogen featured heavily — Gastech rebranded itself as "the global conference for gas and energy" partly to signal this shift. The main debate was not whether hydrogen had a future in hard-to-abate sectors (broad consensus: yes) but whether the production pathway would be blue (natural gas + carbon capture and storage, or CCS) or green (electrolysis powered by renewables).
Shell, TotalEnergies, and Equinor all outlined blue hydrogen projects anchored to their existing upstream gas infrastructure in Norway, the Gulf, and North America. The cost advantage of blue hydrogen — roughly USD 1.5–2.5/kg vs USD 3.5–6/kg for green in 2023 — was cited as the near-term commercial reality. Green hydrogen advocates at the conference, including representatives from IRENA, argued electrolyser costs were falling on a trajectory analogous to solar panels and would reach cost parity before 2030 in high-renewables markets.

Methane regulation tightens
A recurring undercurrent at Gastech 2023 was the tightening global methane regulatory environment. The EU methane regulation for the energy sector — requiring operators to measure, report, and verify methane emissions, and eventually imposing intensity limits on imported LNG — was advancing through the legislative process. For US LNG exporters, this created a new compliance dimension: buyers in Europe were starting to request methane intensity certificates alongside supply contracts.
The Oil and Gas Methane Partnership 2.0 (OGMP 2.0) standard, which requires bottom-up measurement rather than estimation, saw several new signatories announced at Gastech 2023, including a number of national oil companies. Critics noted that self-certification remained the norm and that independent satellite-based detection (via systems like Kayrros or MethaneSAT) consistently found higher emissions than reported values.
Gas demand outlook
The IEA's presentation at Gastech 2023 projected global gas demand peaking in the late 2020s under its Announced Pledges Scenario, while acknowledging it could plateau rather than fall sharply if Asian economies remained gas-hungry. The IEA Gas Market Report Q3 2023 provided the detailed supply-demand backdrop.
For transport fuels, the gas story connects to prices through two channels: CNG vehicle economics (see our CNG glossary entry) and the gas-to-oil switching effect on diesel markets. Both channels suggest that a well-supplied global LNG market — which Gastech 2023 suggested was coming by 2026–2027 as new capacity arrives — would moderate the risk of future diesel price spikes driven by gas shortages. The OPEC International Seminar 2024 captured a similar tension on the oil side.
Frequently asked questions
What is Gastech?
Gastech is one of the world's largest annual conferences for the gas and LNG industry. It brings together executives from national oil companies, LNG producers, utilities, equipment suppliers, and governments to discuss supply, trade, technology, and policy.
What was the main theme at Gastech 2023?
The dominant theme was LNG as a bridge fuel: how the post-Ukraine energy crisis had accelerated European LNG import infrastructure and whether long-term supply contracts could justify new liquefaction capacity while still meeting climate commitments.
How does gas and LNG relate to pump petrol prices?
LNG infrastructure shapes the gas-to-oil switching calculation. When gas prices spike, industrial and power users switch to oil products, raising diesel and fuel oil demand and lifting crack spreads. LNG supply security therefore indirectly affects what drivers pay at the pump.
What hydrogen commitments were announced at Gastech 2023?
Several major producers including Saudi Aramco, Shell, and TotalEnergies outlined blue hydrogen production targets tied to their existing gas infrastructure, with the focus on carbon capture and storage cost reduction rather than electrolytic green hydrogen.
