IHI：火力発電からCO2半減：アンモニア活用技術（動画）：
IHI: CO2 halved from thermal power generation: Ammonia technology：
IHI：火力发电减少了一半的二氧化碳：氨利用技术
IHI：
アンモニアを活用して、火力発電からの二酸化炭素の排出を半分以下に抑えます。
新技術を、機械メーカーIHIが開発しました。
二酸化炭素の排出削減につながる方法として、期待を集めそうです。
天然ガスとアンモニアを混焼：
IHIは、天然ガスとアンモニアを、一緒に燃やして発電する混焼という方法を使っています。
2000キロワットの発電設備：
アンモニアの比率を60％に高めても安定的に発電できる技術を開発しました。
アンモニアの特徴：
アンモニアは燃やしても二酸化炭素が出ないという特徴があります。
今回開発された技術
天然ガスだけを燃料にした場合と比べて二酸化炭素の排出を40％に抑えることができる。
IHIは工場での自家発電などとして実用化を目指す方針です。
日本のNEDO：
比較的大きな発電設備で、アンモニアの比率を60％まで高めた技術は、世界で初めてだということです。
脱炭素社会の実現：
政府の実行計画でアンモニアは「有効な燃料」とされ、新たな技術は排出削減につながる方法として期待を集めそうです。

IHI Yokohama Facility to Initiate World’s First Blue Ammonia-Fueled Gas Turbine Tests
in Keeping with Joint Oil Producing Nation and User Efforts to Build Eco-Friendly Ammonia Value Chain｜
October 23, 2020- press
IHI Corporation
announced today that a 2,000-kilowatt-class gas turbine at its Yokohama Works will begin co-firing tests on October 26 to employ blue ammonia as a fuel.
the Saudi Aramco Oil Company
This initiative will be a world first with gas turbines.
IHI is collaborating with a program that the Institute of Energy Economics, Japan, and the Saudi Aramco Oil Company
are undertaking to demonstrate the feasibility of the blue ammonia supply chain (see note 1).
ammonia is called “blue”
This ammonia is called “blue” as it is carbon-neutral.
That is because the process for producing ammonia from natural gas
entails capturing carbon dioxide emissions using them for enhanced oil recovery and for carbon capture and utilization.
IHI is undertaking research and development
to improve ammonia co-firing technology for gas turbines and coal-fired burners.
This is under a project that Japan’s New Energy and Industrial Technology Development Organization (see note 2)
commissioned to develop and commercialize advanced thermal power technologies and conduct advanced research into ammonia co-firing technology for such facilities.
This project
aims to raise the ammonia co-firing ratio to more than 50% on a calorific value basis.
IHI is also employing blue ammonia in co-firing tests with pulverized coal at a large-capacity combustion test facility within its Aioi Works in Hyogo Prefecture.
This is incidentally the world’s first blue ammonia and coal co-firing test.

Saudi Arabia Sends Blue Ammonia to Japan in World-First Shipment
Japan will use fuel to create electricity, Saudi Aramco says
Asian country wants to be a world-leader in hydrogen fuels
Blue ammonia
is a feedstock for blue hydrogen, a version of the fuel made from fossil fuels with a process that captures and stores C02 emissions.
Hydrogen from renewable energy that creates no emissions is known as green hydrogen.
Saudi Arabia, the world’s biggest oil exporter,
is increasingly trying to counter its reputation for producing dirty energy. In recent months,
Aramco
has highlighted the low volume of greenhouse gases emitted from pumping Saudi crude, programs to boost gas production and plans to grow carbon-absorbing mangroves.
