パワー・トゥ・ガス市場規模、シェア、動向、予測、2026-2034年

世界のパワー・トゥ・ガス市場規模は、2025年に4,700万米ドルに達しました。IMARCグループは、今後、同市場が2034年までに1億370万米ドルに達し、2026年から2034年にかけて年平均成長率（CAGR）8.92%で成長すると予測しています。再生可能水素への需要の高まり、燃料電池電気自動車（FCEV）の利用拡大、電解槽技術への需要増加などが、市場を牽引する主な要因となっています。

パワー・トゥ・ガス（P2G）とは、電気エネルギーをガス生成によって化学エネルギーに変換するプロセスです。電気分解プロセスを利用して水素ガスを生成し、これを最終エネルギーキャリアとして直接使用したり、第2段階のプロセスでメタン、合成ガス、電力、液体燃料、または化学物質に変換したりします。再生可能エネルギーを天然ガスに変換し、既存の天然ガスインフラに貯蔵するのに役立ちます。また、風力発電所からの余剰電力を変換し、地域の送電網に供給したり、周辺の産業企業に送ったり、地域のガソリンスタンドに供給したりするのに役立っています。エネルギーを他の容易に貯蔵可能なエネルギーキャリアに変換することで長期間貯蔵し、運転を制御することで電力網への負荷を軽減します。さらに、微生物が有機物に分解されて燃料を生成する嫌気性消化プロセスも促進します。より環境に優しい天然ガスミックスへの移行に効果的な手段であるため、P2Gの需要は世界中で高まっています。

Report Overview

The global power-to-gas market size reached USD 47.0 Million in 2025. Looking forward, IMARC Group expects the market to reach USD 103.7 Million by 2034, exhibiting a growth rate (CAGR) of 8.92% during 2026-2034. The growing demand for renewable hydrogen, rising utilization of fuel cell electric vehicles (FCEVs), and the escalating demand for electrolyzer technology represent some of the key factors driving the market.

Power-to-gas (P2G) is a process wherein electrical energy is converted into chemical energy through gas production. It relies on the electrolysis process to produce hydrogen gas that can be used directly as a final energy carrier or converted to methane, synthesis gas, electricity, liquid fuels, or chemicals during the second stage process. It assists in converting renewable energy into natural gas and storing it in existing natural gas infrastructure. It also aids in transforming surplus power from wind farms, which can be fed into the local grid, delivered to surrounding industrial companies, or provided to regional filling stations. It stores energy for an extended period by converting it to other easily storable energy carriers while reducing the load on the electricity grid by controlling operations. It also facilitates the anaerobic digestion processes, where microorganisms are broken-down to organic matter to produce fuels. As it is an effective means of transitioning to a greener natural gas mix, the demand for P2G is rising across the globe.

Power-to-gas Market Trends:

At present, there is a rise in the demand for renewable hydrogen, which has the potential to decarbonize multiple sectors across the globe. This, along with the escalating demand for electrolyzer technology due to its cost-effectiveness, represents one of the key factors supporting the growth of the market. Besides this, there is an increase in the demand for hydrogen as a clean fuel in light vehicles, railways, and marine applications to reduce greenhouse gas emissions around the world. This, coupled with the growing utilization of fuel cell electric vehicles (FCEVs), which require high-purity hydrogen fuel, is positively influencing the market. In addition, various technological developments in hydrogen production technology and hydrogen engine technology are offering lucrative growth opportunities to industry investors. Moreover, the rising demand for P2G technology to use existing gas transmission infrastructure for transporting energy in the form of green hydrogen over long distances is propelling the growth of the market. Apart from this, various benefits offered by P2G technology over conventional energy storage technologies, such as higher power storage capacity and longer discharge times, are strengthening the growth of the market. Additionally, the increasing demand for P2G technology due to the falling costs of renewable energy technologies, such as solar and wind, is bolstering the growth of the market.
