EW Origin SDK and new EW Zero app supporting renewables markets around the world

Digitizing Renewable Energy Procurement

In the past, markets for energy attribute certificates (EACs) around the world have been criticized for being analog, opaque, and cumbersome in an era of digital convenience and transparency. But now with the support of our EW Origin SDK, we’re seeing fast-growing momentum behind digitized renewable energy markets from the Americas to Europe to Asia—now with the recently launched EW Zero app to connect them and make digitally sourcing renewables globally even easier.

From the beginning, making renewable energy procurement faster and easier for buyers and sellers alike has been a core use case for the Energy Web tech stack—and the motivation behind our flagship SDK, EW Origin, to support applications and renewable energy markets around the world. When TEO: The Energy Origin—incubated within French multinational energy company, long-time Energy Web member, and EW Chain validator node host Engie—became the first application to migrate onto the Energy Web Chain during the second half of 2019, it further cemented renewables’ place in the ecosystem.

Then 2020 brought Release C to EW Origin, the first major release since the EW Chain launched 9 months earlier, followed by several smaller releases. One big upgrade was the adoption of a multitoken standard for EACs, with a non-fungible token for permanent attributes such as generation type and location and fungible tokens for ‘tradeable’ attributes such as a particular megawatt-hour of renewable generation from that asset.

In tandem, 2020 saw a significant expansion in the potential for digitized, blockchain-based renewable energy markets. As corporate renewable energy buyers continued their procurement evolution, they began looking beyond emissionality and locationality for better ‘proof of impact’ solutions. Electric vehicles took center stage as the next dominant class of renewable energy buyers. ‘Green blockchains’ gained industry attention. While green hydrogen burst onto the scene.

Along the way, more than half a dozen projects announced across four continents saw renewable energy markets globally take a big step toward digitization, leveraging EW Origin.

Sonnen Group Leverages EW Chain, EW Origin for Virtual Power Plant That Saves Wind Energy, Reduces Grid Congestion
sonnen unveiled a new virtual power plant (VPP) in northeastern Germany that leverages the EW Chain and EW Origin SDKs. A network of distributed residential energy storage systems comprise the VPP, which is used to absorb surplus wind generation and thus avoid curtailment of renewable energy by charging the batteries when wind energy is abundant. An application built using EW Origin matches forecasted wind energy oversupply with available storage capacity in the VPP. Financial settlement occurs on the EW Chain using EW Dai, a stablecoin digital currency that mirrors conventional Dai on Ethereum.
“With a flexibility market for renewable energies and the automatic exchange of supply and demand via the digital exchange ‘EW Origin,’ we are realising the next step towards a smart grid that can deal much more flexibly with fluctuations from renewable energy.”

Central American Electricity Retailer Mercados Eléctricos Completes First Stage of Digital I-REC Trading Platform Built with EW Origin
MERELEC built a pilot marketplace platform aligned with The International Renewable Energy Certificate (I-REC) Standard and onboarded about 20 renewable energy devices in El Salvador onto the pilot platform to trade I-RECs from verified renewables generation. Up to 200 devices in El Salvador with a total capacity of more than 1.3 GW are planned to be added to this pilot platform in the near future before onboarding more assets from across the region. Assets range from small-scale solar PV and micro-hydro systems to utility-scale renewable facilities such as large hydro, geothermal, and biogas/biomass. MERELEC’s platform was built using the EW Chain and EW Origin SDKs.
“We expect that this platform will ultimately help us grow our renewable energy business and help our customers obtain the most profitable and resilient economic prospects for their renewable systems by selling renewables directly to buyers in a lower-cost, more-efficient way.” 

—Carlos Chávez, Director of Projects & Investments, MERELEC

Foton Launches EW Chain-based I-REC Marketplace in Turkey
Foton’s digital, blockchain-based platform for tracking and trading international renewable energy certificates (I-RECs) aligns with The International REC Standard, the EAC standard in more than 30 countries across the globe, and represents a first-of-its-kind commercial pilot for renewable energy trading in Turkey. Foton became Turkey’s official I-REC issuer in 2020. The renewable energy trading platform integrates with the open Energy Exchange Istanbul (EXIST) platform to securely access accurate power generation data.
“We are a proud member of Energy Web and believe strongly that digital technologies will help energy transition accelerate. As Turkey’s local I-REC issuer, Foton works actively to register DERs; being a marketplace operator, Foton enables corporate consumers to reach transparent bids and offers.”

Utility NV Energy and Blockchains LLC Announce EW Chain Pilot for Nevada’s Residential Solar Market
NV Energy, a public utility serving more than 1.4 million customers throughout Nevada, and Blockchains LLC announced the Portfolio Energy Credit (PEC) Trading Pilot Project. Whereas typical EACs are generated and tracked at the megawatt-hour (MWh) level, Nevada’s PECs are created at the much smaller kilowatt-hour (kWh) level, making them well-matched to the output from residential solar PV systems. The pilot was expected to show how a blockchain-based solution running on the EW Chain can support the entire PEC lifecycle: the registration of renewable energy assets (e.g., rooftop solar systems) and their owners; the certification of PECs; PEC tracking; and finally the sale, transfer, and retirement of PECs.
“NV Energy is excited to implement this pilot in partnership with Energy Web and Blockchains LLC. This experience will give us a better understanding of how open-source blockchain technologies can create value for our customers, reduce our internal costs, and provide access to portfolio energy credit value to more customers who generate renewable energy across Nevada.”

Deutsche ErdWärme Joins Energy Web, Brings Carbon-free Geothermal Energy to Germany’s Energy Transition
Founded in 2015, Deutsche ErdWärme (DEW) has quickly become Germany’s largest private developer of geothermal energy plants, spanning heat, electricity, and combined heat-and-power projects. DEW’s geothermal development is focused on the Upper Rhine Valley in southwest Germany, along the border with France, a region with some of the best geothermal potential not only in Germany, but also all of mainland Europe.
“Geothermal energy is a unique renewable energy as it provides baseload energy. Our plants can both produce heat and electricity and are therefore highly flexible. This flexibility is something we also expect and need from a decentralized future energy system. In order for this to succeed, we want to be actively involved in the solutions and see Energy Web as an excellent platform.”

EW Zero: The Digital Gateway to Zero-Carbon Renewable Energy

During the second half of 2020, we unveiled EW Zero, an application to find and digitally source verified, emissions-free renewable energy globally. EW Zero came into the world with a bang. We teamed up with the XRP Ledger Foundation and Ripple to decarbonize the XRP Ledger. It marked the first ever widespread decarbonization of a public blockchain, addressing a significant environmental challenge for blockchain technologies around the world.

“The crypto industry, with its questionable carbon footprint, now has a convenient way to showcase its green cred on a verified (rather than trusted) basis,” declared CoinDesk. “This is a step in the right direction for a relatively young industry that could become one of the first to be carbon-neutral.”

“We’re proud to partner with Energy Web on an initiative with such a positive upside for climate action and clean energy, not just as co-developer of the technological solution, but also as one of its first adopters. Energy Web and its ecosystem of more than 100 major energy companies globally to make ‘green blockchains’ the new de facto standard for the distributed ledger industry will play a key role in building a sustainable future for all.” 
—Brad Garlinghouse, CEO, Ripple
Following on the heels of the EW Zero launch and joint announcement with Ripple, the Good Energies Foundation awarded Energy Web a grant to commercialize EW Zero. The grant will enable Energy Web to bring EW Zero to market over the next year by commercializing the software and releasing tools that enable suppliers (e.g., renewable energy developers, owners, and operators) to post renewables for sale on EW Zero. Such integration protocols will enable companies to connect commercial renewable energy platforms — including but not limited to the various marketplace platforms built over the past two years with various Energy Web member organizations such as PTT, Foton, and Mercados Eléctricos — to ensure sufficient renewable supply is made available for buyers.

“We are excited to support Energy Web for a project with transformational potential for global renewable energy markets. We hope our grant for EW Zero will help scale investments in new renewable energy projects, particularly in developing countries, by reducing market friction and streamlining I-REC and other energy attribute certificate transactions between buyers and sellers to expand clean energy access to more communities across the globe.”
