The Tooele Army Depot in Utah will become one of the first military bases to get a utility-sized renewable energy project as the Department of Defense moves closer to its goal of obtaining 25 percent of its electricity from renewable sources.

Infinia was chosen to build a farm of its unique solar dishes on vacant land at the base, which will include 430 Infinia Power Dishes, 22 feet in diameter, that revolve to track the sun throughout the day. The parabolic mirrors focus on the sun's rays, heating up a chamber of helium gas, which drives a piston to generated electricity. Those components will all be manufactured on the base.

"We want to be secure, we want, if the power grid goes down, we still want to be able to do business here," said Tooele Army Depot Business Development Specialist Raymond Torres to KSL.

Although only one windmill currently stands at the base, Rocky Mountain Power is building a high-voltage transmission line nearby and the Army plans to provide land to developers with renewable energy proposals. 

Infinia plans to begin construction later this year, generating electricity by November.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
