NEDO initiates program for using hydrogen in steelmaking

The steel industry emits as much as 40% of Japan’s industrial sector’s CO2 during the manufacturing process. The blast furnace method, which is currently used in steel mills in Japan, uses mainly coke (coal) to reduce iron ore to produce steel, leading to CO2 emissions. NEDO has been working on a hydrogen reduction process technology […]

Japan’s NEDO initiates program on fuel ammonia supply chain

As ammonia, like hydrogen, does not emit CO2 when burned, it is expected to be used as a decarbonized fuel for power generation and ships to achieve carbon neutrality. In particular, ammonia is expected to replace conventional fossil fuels in power generation, thereby promoting the decarbonization of thermal power generation. Ammonia can also be used […]

NEDO will reduce CO2 emissions in the concrete and cement industries

https://www.nedo.go.jp/news/press/AA5_101510.html The Japanese Ministry of Economy is financing a ten-year joint project with JP¥ 55 billion (approx. € 390 million) to reduce CO2 emissions in concrete construction in a cost-neutral manner and to recover CO2 from limestone. The CO2 is then to be reprocessed into carbonates and these into cement. Seven Japanese companies and two […]

Mitsui Chemicals begins manufacturing bio-polypropylene (bio-PP) from biomass naphtha

The biomass naphtha prepared from vegetable oil waste and residual oil is supplied from Finland’s Neste. Mitsui Chemicals studies since many years a bio-based process for the production of isopropanol from biomass, using recombinant E. coli as a catalyst. Isopropanol is then further processed to bio-PP. The process is currently run at 1500 L scale […]

18-11 Green Earth Institute uses Corynebacterium resting cells to prepare green chemicals from formaldehyde

In an artificial metabolic system, the formaldehyde is added via aldolase, to appropriate cosubstrates forming 2,4-dihydroxybutyric acid (DHB), homoserine (hSer), and 1,3-propanediol (PDO). As an aldolase, hpal from Escherichia coli was used. It accepts also other aldehydes. The study is considered a proof of principle that high-cell density cultures of resting cells of C. glutamicum […]

5-11 NEDO launches R&D program for hydrogen aircrafts

The project aims to increase the ratio of participation in international joint development of airframes and engines (currently about 20-30%) by maximizing the strengths of Japan’s elemental technologies, such as hydrogen and materials. The project will also contribute to the decarbonization of the aviation sector. Implementation period: FY2021 – FY2030  Budget: 21.08 billion yen (scale […]
