他们的业务
Ohmium专注于通过先进的质子交换膜(PEM)电解槽生产绿色氢气。这些电解槽利用水和可再生能源生成高纯度氢气,而不依赖化石燃料(来源:ohmium.com)。他们的旗舰产品Lotus Mark 2电解槽具有超模块化设计,包括集中式水净化单元、基于乙二醇的冷却系统和专有电力电子设备,所有这些都集成在一个紧凑的占地面积内,允许垂直堆叠并在各种气候条件下部署(来源:ohmium.com)。该公司提供全球远程监控和维护等服务,确保从兆瓦到吉瓦级别的可扩展性,通过在印度制造的标准化设计(来源:ohmium.com)。目标市场包括工业应用、电力生产和运输燃料,重点关注在美国、欧洲、印度和中东等地区难以脱碳的行业(来源:ohmium.com)。Ohmium的竞争优势在于其高电流密度、动态升降能力和优越的铱利用率,使其在与ITM Power和西门子能源等行业竞争对手的竞争中处于有利地位(来源:ohmium.com)。
项目与业绩
Ohmium已建立超过2吉瓦的强大全球项目管道,证明其在极端条件下的可靠性(来源:ohmium.com)。其中一个显著项目是为克罗地亚INA里耶卡炼油厂提供10兆瓦PEM电解槽,旨在实现运营和燃料运输的脱碳,得到欧盟复苏与韧性基金的支持(来源:advancedbiofuelsusa.info)。在西班牙,Ohmium承诺每年提供多达52吨的绿色氢气,用于EFFI SOLAR GREENH2 PORTUARIO项目,该项目将替代气焰中的甲烷,显著减少二氧化碳排放(来源:ohmium.com)。此外,该公司还签署了一份300兆瓦PEM电解槽的条款清单,用于南欧的OFFSET海上浮动绿色氢气和氨项目,预计到2029年开始生产(来源:canvasbusinessmodel.com)。Ohmium的合作伙伴包括与Invenergy在纳尔逊能源中心进行涡轮冷却的合作,以及参与印度首个绿色甲醇工厂(来源:cbinsights.com)。
近期发展
在2023年,Ohmium成功筹集了2.5亿美元的C轮融资,由TPG Rise Climate主导,旨在将制造能力扩大到每年2吉瓦,并扩大研发工作(来源:esgtoday.com)。这紧随其后的是2022年4月的4500万美元B轮融资,使总融资额到2025年底达到3.112亿美元(来源:cbinsights.com)。该公司还在印度启用了PEM电解槽的千兆工厂,预计每年将减少400万吨二氧化碳排放(来源:ohmium.com)。在2024年,Ohmium获得了南欧300兆瓦项目的条款清单,并与印度首个绿色甲醇工厂达成合作,展示了其在绿色氢气领域扩展足迹的承诺(来源:canvasbusinessmodel.com)。到2025年,Ohmium获得了UL Solutions对使用水电解的氢气发生器的首个工业认证,进一步巩固了其在市场中的地位(来源:ohmium.com)。
在这里工作
Ohmium提供多样化的职位,包括工程、制造、运营、研发、合规和高管职位,吸引来自电解槽和燃料电池技术等各个行业的人才(来源:ohmium.com)。该公司主要在其位于加利福尼亚州弗里蒙特的总部招聘,同时还提供与其在印度的千兆工厂及美国、欧洲和中东的项目相关的机会(来源:builtin.com)。Ohmium的文化强调创新问题解决、快速执行和对人权合规的承诺,反映了其推动高效PEM技术的使命(来源:ohmium.com)。虽然具体的员工福利没有公开记录,但该公司通过全球远程监控和性能保证的角色促进运营福利(来源:ohmium.com)。求职者被鼓励访问他们的职业页面以获取当前职位信息(来源:ohmium.com)。
