Largest ZEBREX? system in the world and the first fuel ethanol plantinstallation in North America; Mitsubishi ZEBREX? technology reduces costs andincreases revenues by an estimated $5 million per year at the Aemetis Low CarbonEthanol Facility in Keyes,CA.

作為世界上較大的ZEBREX?系統(tǒng)和在北美建設(shè)的第一個(gè)燃料乙醇工廠，在加利福尼亞州Keyes的Aemetis低碳乙醇工廠使用了三菱ZEBREX?技術(shù)，該技術(shù)每年可降低生產(chǎn)成本并增加收益約500萬美元。

CUPERTINO, Calif. – August 31, 2022 – Aemetis, Inc. (NASDAQ: AMTX), a renewable naturalgas (RNG) and renewable fuels company focused on negative carbon intensity products, completedthe installation and commissioning at the Keyes ethanol plant in California of the firstMitsubishi ZEBREX? system in North America, reducing overall energy use and lowering the carbon intensityof ethanol. The system is now fully operational, reducing energy costs and increasing biofuel value by more than $5 million per year.

加利福尼亞州CUPERTINO——2022年8月31日——Aemetis，Inc.（納斯達(dá)克：AMTX），一家專注于負(fù)碳強(qiáng)度產(chǎn)品的可再生天然氣（RNG）和可再生燃料公司，在加利福尼亞州的Keyes乙醇工廠完成了北美首個(gè)三菱ZEBREX?系統(tǒng)的安裝和調(diào)試，減少了總體能源使用并降低了乙醇的碳強(qiáng)度。該系統(tǒng)現(xiàn)已全面運(yùn)行，降低了能源成本，每年增加生物燃料價(jià)值超過500萬美元。

The cost of equipment, engineering and installation of the Mitsubishi ZEBREX? systemwas approximately $10 million. Aemetis expects to receive more than $1 million of grant funding fromthe PG&E and CPUC Energy Efficiency Program in support of theproject.

三菱ZEBREX?系統(tǒng)的設(shè)備、工程和安裝費(fèi)用約為1000萬美元。Aemetis預(yù)計(jì)將從PG&E和CPUC能源效率計(jì)劃獲得超過100萬美元的贈(zèng)款，以支持該項(xiàng)目。

The Mitsubishi Chemical Corporation ZEBREX? ethanol dehydration system was commissionedafter several years of engineering design, fabrication, installation and testing at the Aemetis 65 milliongallon per year, low carbon ethanol plant. The patented ZEBREX? technology replaces theenergy-intensive molecular sieve ethanol dehydration process used by most fuel ethanol plants in the world. TheAemetis plant upgrade is the largest implementation of the ZEBREX? systemworldwide.

三菱化學(xué)株式會(huì)社ZEBREX?乙醇脫水系統(tǒng)經(jīng)過多年的工程設(shè)計(jì)、制造、安裝和測試，在Aemetis 6500萬加侖/年低碳乙醇工廠投入使用。ZEBREX?技術(shù)取代了世界上大多數(shù)燃料乙醇工廠使用的能源密集型的分子篩乙醇脫水工藝。Aemetis工廠升級(jí)實(shí)施的是全球最大的ZEBREX?系統(tǒng)。

The upgrade from the traditional Pressure Swing Adsorption (PSA) ethanol dehydration process tothe ZEBREX? system has reduced petroleum natural gas consumption at the Keyes facility by morethan 20%, which is estimated to provide energy savings of approximately $3.4 million peryear.

從傳統(tǒng)的變壓吸附（PSA）乙醇脫水工藝升級(jí)為ZEBREX?系統(tǒng)，使Keyes工廠的石油天然氣消耗量減少了20%以上，預(yù)計(jì)每年可節(jié)約能源約340萬美元。

Additionally, by reducing the amount of fossil fuel energy used in the production process,Aemetis expects to receive a lower carbon intensity (CI) score for the fuel ethanol produced at the Keyesplant, which will increase revenue for each gallon of fuel ethanolsold.

此外，通過減少生產(chǎn)過程中化石燃料使用量，Aemetis預(yù)計(jì)Keyes工廠生產(chǎn)的燃料乙醇將獲得較低的碳強(qiáng)度（CI）分?jǐn)?shù)，這將增加每加侖燃料乙醇的銷售收入。

“Implementation of the Mitsubishi ZEBREX? technology at the Aemetis Keyes plant completesanother significant project as we transition our ethanol production process from petroleum-based energysources to renewable electricity,” said Andy Foster, President of Aemetis Advanced Fuels Keyes, Inc.“Our engineering team worked closely with Mitsubishi in Japan to customize the design of the systemfor large-scale fuel ethanol production. The ZEBREX? technology is delivering as promised andMitsubishi has been an outstanding partner throughout this multi-year process,” addedFoster.

Aemetis Advanced Fuels Keyes總裁安迪·福斯特（Andy Foster）表示：“隨著我們將乙醇生產(chǎn)工藝從石油基轉(zhuǎn)變?yōu)榭稍偕茉矗珹emetis Keyes工廠采用的三菱ZEBREX?技術(shù)完成了另一個(gè)重要項(xiàng)目”。“我們的工程團(tuán)隊(duì)與日本三菱密切合作，為客戶定制設(shè)計(jì)大規(guī)模燃料乙醇生產(chǎn)系統(tǒng)。ZEBREX?技術(shù)實(shí)現(xiàn)了承諾，三菱在這一多年過程中一直是一個(gè)出色的合作伙伴”，F(xiàn)oster補(bǔ)充道。

The Aemetis carbon intensity reduction projects at the Keyes ethanol plant include a 1.9-megawattsolar microgrid with battery backup that will produce zero carbon electricity to reduce natural gas usage, anda Mechanical Vapor Recompression (MVR) system using electric motors furthers the transitiontorenewableelectricity.

Aemetis Keyes乙醇工廠的碳強(qiáng)度降低項(xiàng)目包括一個(gè)1.9兆瓦的太陽能微電網(wǎng)，配備電池備用，將產(chǎn)生零碳電力，以減少天然氣的使用，以及一個(gè)使用電機(jī)的機(jī)械蒸汽再壓縮（MVR）系統(tǒng)，進(jìn)一步向可再生電能過渡。

Combined, the Aemetis carbon reduction projects are expected to reduce the use of petroleum naturalgas at the Keyes biofuel facility by 85%, which will save the company more than $1 million per monthinnatural gas costs and provide a significant increase in the value of the ethanol produced at theplant.

綜上所述，Aemetis的碳減排項(xiàng)目預(yù)計(jì)將Keyes生物燃料工廠石油天然氣的使用量減少85%，這將為公司每月節(jié)省超過100萬美元的天然氣成本，并大幅提高該工廠生產(chǎn)的乙醇價(jià)值。

Aemetis is focused on producing below zero carbon intensity renewable fuels, including negativecarbon intensity renewable natural gas (RNG), sustainable aviation fuel (SAF), renewable diesel (RD),and bioethanol. Aemetis projects maximize the use of agricultural waste or by-products as lowcarbon feedstocks to produce renewable fuels, while leveraging the value of federal and state carbonreduction programs. Aemetis is developing two carbon capture and sequestration (CCS) wells near itsbiofuel facilities in Central California that are expected to store about 2 million metric tonnes per year ofCO2.

Aemetis專注于生產(chǎn)負(fù)碳強(qiáng)度的可再生燃料，包括負(fù)碳強(qiáng)度可再生天然氣（RNG）、可持續(xù)航空燃料（SAF）、可再生柴油（RD）和生物乙醇。Aemetis項(xiàng)目最大限度地利用農(nóng)業(yè)廢物或副產(chǎn)品作為低碳原料生產(chǎn)可再生燃料，同時(shí)利用聯(lián)邦和州的碳減排計(jì)劃的價(jià)值。Aemetis正在加州中部生物燃料設(shè)施附近開發(fā)兩口碳捕獲和封存（CCS）井，預(yù)計(jì)每年可儲(chǔ)存約200萬公噸的二氧化碳。
