经过两年的努力,Terraform 的开创性团队成功展示了他们通过先进的电转气 (PtG) 技术将阳光和空气转化为合成天然气的能力。 他们的创新系统利用尖端的氢电解、直接空气捕获和甲烷化子系统,将电力和空气转化为经济实惠的无化石燃料。 这一突破标志着该技术发展的关键飞跃,并有助于利用来自可再生能源的丰富、廉价和可靠的能源实现可持续的未来,同时最大限度地减少对生态和气候的影响。 Terraform 的独特方法在于采用现有的工业技术来创建专为可再生能源使用而定制的高效且具有成本效益的解决方案。 他们革命性的技术进步显着降低了氢气和大气二氧化碳捕获的生产成本,使合成天然气的价格可与传统方法相媲美。 通过将超廉价太阳能与低成本绿色氢和二氧化碳捕获相结合,Terraform 为创造具有市场竞争力的商品级电燃料替代品铺平了道路。 他们技术精湛的工程团队不断突破界限,以实现绿色氢气和直接空气捕获成本的大幅降低。 通过实施针对可变可再生能源优化的已知工业流程,他们削减了创新电解槽(<100 美元/千瓦)、太阳能发电(<20 美元/兆瓦时)和直接空气捕获系统(<600 美元/吨)的资本支出-Year-CO2),代表了行业标准的显着改进。 Terraform 专注于快速适应和内部生产,旨在彻底改变能源行业,并为持续增长、繁荣和环境管理奠定基础。 他们首次生产的 Terraformers 的预订正在接受中,因为他们准备增加产量以满足不断增长的需求。

在英国,发电正在转向可再生能源,特别是风能和太阳能。 然而,这种转变带来了挑战,因为这些来源的间歇性导致供应过剩期间的负定价和赤字情况下的高价格,尽管不可再生替代品的成本不断增加。 目前,国家电网每年支付约 10 亿英镑,用于在供应过剩期间关闭风电场,并大力投资建设天然气峰值发电厂,该发电厂受法律限制每年最多只能运行 10 天。 预计情况会进一步恶化,预计每年的削减费用将达到 40 亿英镑。 拟议的解决方案涉及整合 TERRAFORM Energy 先进的绿色氢系统,该系统可以在电价较低或为负值时产生氢气,并以氢气的形式出口能源。 这些系统还可以接受减少的可再生能源而不是关闭,从而缓解可再生能源过剩的问题。 此外,他们可以利用多余的天然气基础设施进行储存和运输,从而有可能完全消除燃烧天然气的需要。 尽管由于气候寒冷,电池不太适合英国市场,与温暖地区相比需要更多的能量存储,但 TerraForm Energy 的替代解决方案在解决可再生能源间歇性挑战方面表现出了希望。

We did it! After two years of hard work we hold in our hands hard proof that the incredible team at Terraform can make synthetic natural gas from sunlight and air, as reported in TechCrunch.

Last Wednesday March 27, 2024, we commissioned our integrated power-to-gas demonstrator. The system converts electricity and air into affordable fossil-free natural gas using proprietary subsystems, developed in-house, for hydrogen electrolysis, direct air capture, and methanation. This marks a major milestone in the technical and commercial development of our technology and another step on the path to our positive vision for the future where everyone has access to plentiful cheap, reliable energy, harvested from renewable carbon and power, with lower ecological and climate impact.

Our core innovation is the utilization of proven and well-understood industrial processes implemented within innovatively simple and cost-effective proprietary technology systems adapted to the daily variations of renewable power for producing cheap sustainable natural gas from sunlight and air. These design and process innovations are responsible for driving production costs down for both their green hydrogen and atmospheric CO2 capture to levels previously thought unattainable. Combining super-cheap solar power with low-cost green hydrogen and CO2 capture are the key to producing commodity-grade electro-fuel alternatives at competitive commodity prices.

Our elite team of engineers have made significant progress towards our stated goals of radically cheaper green hydrogen and direct air capture CO2. We follow a simple playbook. Adapt a known industrial process to ultra-cheap solar power by a) radically reducing capex to compensate for lowered utilization and b) developing processes that are robust to variations in power due to weather, as well as diurnal and seasonal power shifts.

First, our innovative electrolyzer converts cheap solar power into hydrogen with current production costs at less than $2.50 per kg of H2. How? To first order, our electrolyzer capex costs <$100/kW, and we’re currently baselining solar PV DC electricity at $20/MWh. There is no hand waving about economies of scale or subsidies here, though we are eligible for the full IRA 45V green hydrogen tax credit, worth $3/kg-H2.

Second, the proprietary direct air capture (DAC) system concentrates CO2 in the atmosphere today for less than $250 per ton. How? Our DAC capex costs <$600/T-year-CO2. Like the electrolyzer, this represents a substantial improvement on the state of the art.

Finally, our in-house multistage Sabatier chemical reactor ingests hydrogen and CO2, producing pipeline grade natural gas, which is >97% methane (CH4). Our reactor uses no rare or expensive catalysts nor cherry-picked data – it handily operates for hours in steady state.

The Terraformer combines these three subsystems into one modular chemical plant, skid-mounted for deployment alongside a solar PV array.

It is particularly cool to develop and build all three of our sub-systems in our castle in Burbank, CA, right across from the long-time home of the fabled Lockheed Skunk Works. In-house production & manufacturing enables faster iteration, lowered supply chain risk, and the successful demonstration of the complete techno-economic model for producing cost-effective fossil-free natural gas.

While I generally prefer understatement, it is hard to overstate the significance of this achievement, which has been two years in the making. Humanity today depends on traditional oil and gas to provide them with a cheap and easily transportable source of energy-dense hydrocarbons, to the tune of 100 million barrels per day, which unfortunately also generates ~50 gigatons per year of CO2 emissions.

The Terraformer unlocks an industrial-scale source of renewable hydrocarbons that breaks our dependence on fossil fuels and lays the foundation for another century of spectacular growth, broad-based wealth creation, and global environmental restoration.

What’s next? We’re taking reservations for our first production Terraformers, and ramping production to meet demand.
